Oh, patents! Purrble™

 Copyright © Françoise Herrmann

Precipitated by a concern for the increased stress that children were experiencing during long lockdown periods, within the context of the COVID 19 pandemic, Purrble™, masterminded by Sproutel Inc., in collaboration with the Committee for Children®, is an animatronic toy, designed to teach children how to self-regulate their emotions. As for the previous Sproutel Inc., toys, such as Jerry the Bear®, targeting children with Type 1 diabetes, and My Special Aflac Duck®, designed for children undergoing cancer treatment, the researched idea, informing the design of the toys, is that, if children are able to care for their special toys, they will not only learn about the ailments that they share with their toys, they will better understand their own treatments, and be able to better cope, with less fear, and anxiety.

With Purrble™, this means learning how to soothe-down-to-a-purr the racing heartbeat of a small, plush, koala-looking toy, called the Purrble™. The assumption is that the experience of soothing Purrble™ will assist children in calming their own emotions. Different from Jerry the Bear® and My Special Aflac Duck®, Purrble™ was designed to be used mostly at home, or at school, outside of medical and hospital contexts. The “live animal” boxes in which Purrbles™ are packaged were even conceived for possible use as little play beds or houses for the plush toy. Made of cardboard, the boxes can also be decorated.  But Purrble™ is much more than a battery-operated plush toy.

With sensors responsive to both calming caress, or fidgeting, coupled to internal controllers for vibration of the accelerating or decelerating heartbeat, and a speaker to produce purring sounds, and simple grunts, sighs and giggles, Purrble™ falls well within the scope of the far more complex animatronic toys, designed and patented by Sproutel Inc., in collaboration with companies such as The American Family Life Assurance Company (AFLAC). In any event, much like its predecessors in the medical domain, Purrble™ took the market by storm, enchanting the 3+ crowd, cooped up in lockdowns with emotions on edge, while promising that potential gains in emotional regulation are “a determinant of lifelong success, being linked to improved graduation rates […]”. (About Purrble)

Below, an image is included of the cute marketed Purrble™ products, no two of which are completely alike. Also included, a short YouTube video, featuring Sproutel Inc., founder and CEO, Aaron Horowitz, and Kate Gallo, Consultant for Product Management at the Committee for Children®

Time Magazine selected the Purrble™ as one of the 100 best inventions of 2021.

World Health Day

Copyright © Françoise Herrmann

The theme for the United Nation’s (UN) World Health Organization (WHO) World Health Day celebrations this year is Build a fairer, healthier world. For this purpose the WHO suggests:

  • ·        Working together
  • ·        Collecting reliable data
  • ·        Tackling inequities
  • ·        Acting beyond borders

A platform with amplified significance in the midst of the COVID-19 pandemic, affecting 131,487,572 people worldwide, as of April 6, 2021, with a global death toll of almost 3 million people (Who COVID 19 Dashboards).  

The WHO COVID19 Dashboards are also posting figures on the status of the global COVID 19 vaccination campaign. As of April 5, 2021, 604,032,357 doses have been delivered. A figure that echoes the 2021 UN WHO World Health Day theme, as global vaccine distribution is also arising in the of midst distribution inequities. Inequities, unsurprising to experts at the UN, such as UNAIDS Executive Director Winnie Byanyima, who perhaps best captured the already emerging controversies with the term vaccine apartheid (Byanyima, 2021; O'Neill, 2021).

 In any event, the observance of World Health Day, in the year 2021, feels more like a Get Well World card, than a celebration of world health, especially when such a tiny microorganism as the CoV2 has so cruelly robbed the world of one of its most powerful tools for healing.

FDA Advisory Committee-recommended! The Pfizer-BioNTech COVID-19 vaccine

 Copyright © Françoise Herrmann

On December 10, 2020, the US Federal Drug Administration (FDA) Vaccine Advisory Committee recommended an Emergency Use Authorization (EUA) for the COVID-19 BNT162b2 vaccine, developed and manufactured by Pfizer-BioNTech, in Germany. Thus, the BNT162b2 vaccine has cleared a major hurdle to become the first, long-awaited, FDA-authorized vaccine in the US, designed for the prevention of COVID-19, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).  A virus that has infected, to date, close to 70 million people worldwide (1.5 million in the US), claiming more than 1.5 million lives worldwide (close to 300 thousand in the US) (WHO Dashboard; JohnHopkins CoV Resource Center). A virus, now raging a second time, that is also paralyzing world economies.

The FDA Vaccine Advisory Committee recommendation comes exactly one week after the United Kingdom authorized the same vaccine for a mass vaccination campaign, on December 3rd; and one day after authorization in Canada, on December 9th. The votes, recommending emergency vaccine use in the US, cast by 17 of the 23 expert scientists on the FDA Vaccine Advisory Committee, kickstarts the FDA authorization process. A process that escalates the Advisory Committee recommendation to the FDA Commissioner, Stephen Hall, who has to sign off on the authorization for emergency use, before US Marshal-escorted shipments of the vaccine, from Germany to every US State, can begin, and Operation Warp Speed kicks off. Vaccinations would then be administered approximately 96 hours, following FDA authorization (Smith & Rahhal, Dec 10, 2020).

The Pfizer-BioNtech COVID-19 vaccine is a nucleoside-modified messenger ribonucleic acid (modRNA) type vaccine (FDA - Pfizer-BioNTech). This means that to produce the vaccine an mRNA strand was modified to code for the coronavirus spike glyco-protein (S). The spike viral glycoprotein S is the red tentacle-like glycoprotein, represented on the surface the SARS coronavirus-2, that gives the virus its unique profile (see image). Once engineered, and covered with protective lipid nanoparticle (NP) carriers, the modRNA strands are then injected into the human body, where the message to produce (harmless) glyco-protein spikes is delivered within human cells. The production of spike glyco-proteins is then believed to trigger an immune response, where the human body creates antibodies against the (harmless) intruding glyco-protein spikes. Antibodies, which will then circulate, ready to mount an attack, in case a person is actually infected with the SARS coronavirus 2, since the antibodies will be able to recognize the glyco-protein spikes, attached to the surface of the (dangerous ) virus, for the purposes of binding to the virus and preventing its replication (extrapolated from Weintraub & Padilla, June 21 2020).

The Pfizer-BioNTech vaccine is supplied in a multi-dose (5-dose) vial stored at extremely low temperature, between -80°C to -60°C (- 112°F to -76°F)].  Once thawed and diluted into five, 0.3 mL, doses, the vaccine has to be injected within 6 hours. Thus, the vaccine’s temperature storage requirements make it difficult to transport and deliver, not to mention almost impossible to use in Third World countries where facilities for such extremely cold storage might not be readily available. The vaccine is otherwise administered as a series of two, 30 µg (0.3 mL) doses, via intramuscular injection, 21 days apart (FDA - Pfizer-BioNTech). Another FDA Advisory Committee recommended that vaccinations in the US begin with health care workers, the elderly in nursing homes, and the staff taking care of them.  

Different sorts of bio-engineering technologies are invoked in the Pfizer-BioNTech vaccine. The Lipid nanoparticle (NP) carrier technology for the modRNA strands is, for example, recited in the following US utility patent applications and patents, granted to BioNtech.

  • US2020/0155671 – Particles comprising a shell with RNA.
  • US2018/0263907 - Lipid Particle Formulations for Delivery of RNA and Water-Soluble Therapeutically Effective Compounds to a Target Cell.
  • US2017/0273907 – Stable formulations of lipids and liposomes.
  • US10576146 – Particles comprising a shell with RNA.
  • US10485884 – RNA formulation for immunotherapy.
  • US9950065 – Particle comprising a shell with RNA.

Oh, patents! EKO System AI-powered assisted diagnosis (5)

 Copyright © Françoise Herrmann

EKO’s wireless auscultation stethoscope and cardiac sensor not only capture body sounds that are transcribed by proprietary software into readable graphs and numeric data. The EKO System also comprises a patented AI-powered method of analyzing the sounds captured and transcribed, in view of assisting physician diagnosis. 

The EKO System AI-powered method of diagnosis assistance consists in comparing the body sounds recorded and transcribed from a patient with those stored in a database of prerecorded health conditions, using a combination of neural-network technology and proprietary machine-learning algorithms designed to update the database. Thus, the EKO System not only enables remote diagnosis within the anticipated context of telemedicine, for cost-effective delivery and continuity of care to remote and underserved populations, and within the unexpected conditions of the COVID-19 pandemic, it also sets itself apart by providing analysis of the sounds captured and transcribed wirelessly. An analysis of sounds captured and recorded, which returns a list of potential conditions, matching specific sample health conditions stored in the database. A list of conditions, including “regular”, presented in their order of likelihood, with or without the matching sound graphs extracted from the database, which the physician, in turn, can use to inform his or her diagnosis. 

The AI-powered  EKO System invention is recited in the utility patent US9973847B2, titled Mobile device-based stethoscope system. The invention recites the hardware and software components of the system, as well as the database architecture and segmentation of sounds, that together comprise the mobile-based stethoscope system, designed “to serve as a decision-support tool for physicians”. 

The matching database sounds are specifically recited for patient heart sounds. However, the scope of the invention extends to other body sounds captured by a stethoscope, such as respiratory or digestive sounds, which would then be compared and matched to a different and corresponding set of pre-recorded conditions, populating the database.

For anyone interested in listening to a variety of body sound conditions, the following videos are extracted from the EKO System sound Libary. The videos respectively provide sounds for heart and lung conditions, in particular: normal heart sound, atrial fibrillation and pericardial rub for heart conditions recorded via EKO Digital Stethoscope; crackles, wheezes and egophony for lung conditions recorded via  EKO Core Digital Stethoscope

Heart sound 




Lung sounds



The abstract of the EKO System AI-powered diagnosis assistance invention is included below.

A mobile device-based stethoscope system that transmits, records, and analyzes sounds to generate a list of matching conditions and facilitates easy attachment across various electronic medical record platforms and other means of communication. The invention is configured to allow the use of either an integrated wireless stethoscope, or an in-line adapter for a conventional stethoscope. Patient sounds are sent from the selected stethoscope head to the mobile device having a software application that allows for the analysis, attachment, and further manipulation of the data.

Terminology - The second (curfew) lockdown (reconfinement sous couvre-feu)

 Copyright © Françoise Herrmann

Beginning November 21, 2020 through December 21, 2020, California is on a curfew lockdown.  A curfew lockdown is a limited form of stay-at-home order where everyone, except essential workers, residing in the Widespread tier Purple-Alert counties has been ordered to stay-at-home, from 10 pm to 5 am the next morning (California All). Curfew lockdown measures were declared by Governor Gavin Newson on November 19, 2020, in an effort to beat the second rising curve of alarmingly high rates of COVID-19 infections, in California, and throughout the USA. Purple tier-alert counties are those counties where COVID-19 is widespread, measured as more than 7.0 cases recorded daily per 100k people, and more than 8% of the population is infected, in the whole county (California All).

In Europe, French President Emmanuel Macron ordered a new national lockdown on Oct. 28 through December 1, 2020 (Macron, Oct. 28, 2020). On the same day, October 28, in Germany, Chancellor Angela Merkel defended new “soft” lockdown measures, effective November 2, for 1 month (Staff, DW, Oct. 28, 2020). Speaking on behalf of the coronavirus and to the coronavirus, the German Chancellor stated:

COVID-19 - ‘I’ve got the perfect host here. These people live all over the planet. They are globally networked and are social creatures, they can’t live without social contacts. They have a hedonistic inclination, they like to party, it couldn’t be any better.’

Humanity – ‘No, virus, have you learnt nothing from evolution? We humans have shown again and again that we are damned good at adjusting to difficult circumstances. We’ll show you that you have chosen the wrong host.’ (Merkel, quoted in Polternam, Oct. 29, 2020.)

In Italy and Spain, where respectively 46,464 and 41,688 deaths have been recorded,  new lockdown measures have also been ordered in an effort to slow the spread of the second wave of the COVID-19 pandemic (Tondo & Jones, Nov. 17, 2020).

On this day, November 22, 2020, The WHO Coronavirus Disease (COVID-19) dashboard is posting a global pandemic infection rate of 57,882,183 confirmed infections, and 1,377,395 deaths.

On this day, in the USA,, the John Hopkins University Coronavirus Resource Center Dashboard is posting, 1,384,651 confirmed cases, and more than a quarter million deaths, specifically 256,163 (JHU CoronaVirus Resource Center).

Oh, patents! Eko DUO wireless stethoscope + ECG for telemedicine (4)

Copyright © Françoise Herrmann


The EKO DUO combines stethoscope + ECG (Electrocardiogram) into a single palm-held device. In a nutshell, the EKO DUO combines a cartful of complicated medical devices into the palm of a user’s hand – not only the clinician’s hand, but most importantly a patient’s hand, within the context of telemedicine.

If cost-effectiveness and the continuity of specialty care, together with other diagnostic and monitoring benefits of telemedicine, were steadily emerging in such contexts as remote and underserved populations, prior to the COVID 19 pandemic, the pandemic abruptly drove mass migration to telemedicine of both urgent and non-urgent care. For example, Mann, et al.,(2020) reported in a study of the NYU Langone Health system that: "Between March 2 and April 14, 2020, telemedicine visits increased from 102.4 daily to 801.6 daily. (683% increase) in urgent care after the system-wide expansion of virtual urgent care staff in response to COVID-19.” Similarly, Mann, et al. reported that non-urgent care ambulatory care visits across specialties, <50 prior to March 19, increased to >1000 video call visits on March 19, and to >7000 in the 10 subsequent days (representing >70% of all ambulatory volume). They stated: “Over an approximately 6-week period, there were 144 940 video visits conducted, involving 115 789 unique patients and 2656 unique providers.“ The only constant reported was the mean satisfaction level (for both patients and providers) which remained 4.38/5 before, and after, the quantum increase in video call visits.

Although the horrific circumstances of the COVID 19 pandemic in NYC were unanticipated (1), indeed unimaginable and still unspeakable, the delivery of care via telemedicine is precisely the sort of context for which the EKO Duo stethoscope + ECG was invented. Recited in the US utility patent US20200107745A1 titled Wireless cardiac sensor, filed on April 9, 2020, the wireless EKO Duo device is designed for patients to use on themselves, at home or in other non-clinical settings. The device is even designed for single-hand patient operation, using a button on the back surface of the device to initiate recordings. (See the image of the back of the Eko Duo sensor, next to a smartphone display of the recorded data, included to the right.)

Heart and lung sounds, and ECG data, are simultaneously captured, respectively via audio transducer and ECG transducer electrodes within the sensor, and wirelessly transmitted to a personal electronic device, such as a smartphone, tablet, or personal computer, using a Bluetooth® link. The personal electronic device is equipped with downloadable software to process the recorded data (e.g.; to display, analyze, store, and/or send the data), and to give instructions to the user on positioning and initiating the recording. In turn, both the captured ECG and phonogram data are then forwarded, via wide-area network, to a healthcare provider, or to a centralized server.

The abstract of the Eko Duo stethoscope + ECG wireless device is included below, together with the Figure 1 drawing of the wireless device, extracted from the patent. The patent Figure 1 shows a front perspective view of the EKO Duo cardiac sensor device 100, comprising the housing 105 for the device circuitry, the ECG transducer electrodes 110A and 110B, positioned on each side of an acoustic transducer 112. When correctly positioned, on the left pectoral region of a user’s chest, the two electrodes 110A and 110B capture the “electrical signals on a person's skin resulting from depolarization of the person's heart muscle during each heartbeat”. Likewise, the acoustic transducer 112, positioned between the two electrodes 110A and 110B, captures the user’s heart and lung sounds. Together the electrodes 110A and 110B, and acoustic sensor 112, capture both mechanical and electrical characteristics of the user's heart. The absence of lead wires for the electrodes prevents entanglement. The EKO Duo cardiac sensor design is further optimized to provide: 1. gripping comfort, 2. secure use against all body types, 3. adequate distance between electrodes for providing accurate signal quality, and 4. sufficient diameter of the audio transducer to provide optimal detection of heart and lung sounds.

A wireless cardiac sensor is provided. The sensor may be utilized by a patient, on themselves, in an at home or other non - clinical environment. A sensor housing contains ECG electrodes and an audio transducer to simultaneously capture heart sound and ECG data with a single device. The ECG electrodes may be positioned on opposite sides of, and preferably adjacent to, an audio transducer sensor, for placement against a user's chest. The wireless cardiac sensor may include a button on a surface opposite the ECG electrodes and audio sensor, facilitating one - handed operation by a patient. The sensor transmits acquired data to a personal electronic device, such as a smartphone, via a wireless communication link. The personal electronic device may in turn transmit data to a centralized server and/or health care provider devices, via a wide area network. [Abstract US20200107745A1]

Oh, patents! Cordless stethoscopes for safe auscultation (1)

Copyright © Françoise Herrmann

Prior to the COVID 19 pandemic, electronic stethoscopes (e.g.; Eko Core, Thinklabs One or Littman 3200) were primarily known and touted for their superior sound quality, sound filtering possibilities (ie.; ambient noise reduction), the benefits of recorded digital data that can be streamed, shared, compared, annotated, forwarded and stored in medical records, and the general portability of the devices with no bulky tubing or earpieces, including their stylish design.

Within the context of the COVID 19 pandemic, Bluetooth-enabled, wireless digital stethoscopes became vital instruments of safety that enabled medical personnel to retain the full protection of their hazmat equipment, while auscultating patients that were infected, or potentially infected.

Interestingly, the following patent US7182733B2, filed Aug. 20, 2003, granted Feb. 27, 2007, titled Cordless stethoscope for hazardous material environments anticipated such threats as contagious diseases spreading through international air travel, coupled with threats of biological and chemical terrorism. Responding to the specific problematic situations of contagious or more generally hazardous environments that require working in hazmat suits, the invention offers safe auscultation, using a cordless stethoscope, equipped with magnetic induction coils for the transmission of auscultatory sounds, and in a later abandoned patent application US20070049838A1 also using radio frequencies. Thus, the inventive auscultation device, whether using magnetic induction or a combination of magnetic induction and radio frequencies, might be used wearing hazmat suits, without breaking any of the protection afforded by the suits, in highly contagious situations. The inventor, Keith Sauerland, specifically states:

It has come to my attention during  preparedness training for dealing with these threats that it is impossible for medical personnel to use a standard stethoscope when wearing a HAZMAT suit without compromising the integrity of the suit. Breaking the protective barrier of the HAZMAT suit defeats the purpose of wearing the suit and places medical personnel at risk.

As illustrated in the patent Figure 3 below, the invention stethoscope hardly looks like a conventional stethoscope. However, it is specifically designed for medical personnel wearing hazmat suits (as illustrated to the right with staff using the Spanish eKuore stethoscope). Specifically, the invention stethoscope is equipped with means for sending and transmitting sounds from an auscultation head to receivers within earpieces, or to a receiver clipped inside the hazmat suit. The preferred mode of transmission and reception is magnetic induction. The housing of the auscultation head is of a shape that compensates for any loss of fine motor skills associated with the use of heavy hazmat suit gloves, and it is fluid-tight so that it can be easily decontaminated. The cordless stethoscope is used outside of the hazmat suit to sense and transmit sounds, from the patient’s body, to a receiving device inside the hazmat suit, which converts the sounds into audible sounds that the user of the cordless stethoscope can interpret. Optionally, the cordless stethoscope may also include a microphone designed to capture voiced communication from the patient, which might otherwise not be heard through a hazmat suit. 

Below the abstract of this invention, together with the patent Figure 3, showing a cross-sectional view of the sound sensing device 20. In particular the patent Figure 3 illustrates the stethoscope head 30, the fluid-tight casing 70,  a power source 80, preferably a dry-cell battery located within the sound sensing device, a transmitter 120, an activation switch 100, inside an activator switch opening 170, with indicator light 210 and indicator light opening 200. The housing 70 has an opening 160 for receiving the stethoscope head 30, comprising a diaphragm 220, and an auscultation bell 230, a low-frequency response microphone 260 for sensing auscultatory sounds produced by the patient, a first fluid-tight cover 240 and fluid-tight members 250 connecting the stethoscope head 30 and opening 160 to maintain the fluid integrity of the housing 70, while also acting to as shock absorbers for the stethoscope head 30. The stethoscope head 30 is connected via circuits to the switch 100 and the transmitter 120.  When the switch 100 is pressed, the microphone 260 is activated. The outside of the housing provides a nonslip grip. A small ring 150 enables to attach the device via a wrist or neck strap (not illustrated in the patent figure) to prevent accidental drop damage. 

A cordless stethoscope for use in hazardous material environments comprising a fluid tight hand held sound sensing device having a stethoscope head for sensing auscultatory sounds, a transmitter for transmitting sounds sensed by the device, a receiver for receiving transmissions from the transmitter and an ear piece for converting the received transmissions into audible sound. The housing is sized and shaped for being grasped by a gloved hand and is fluid tight for decontamination purposes. The sound sensing device may further comprise a microphone for sensing otherwise inaudible voice communications from a patient. The transmitter and receiver preferably uses magnetic induction transmissions to transmit sounds through barriers such as hazardous material suits that may be worn by clinicians during treatment of patients in possible hazardous material situations.

International Day of the Girl Child

 Copyright © Françoise Herrmann

On October. 11, 2020, UN Women celebrates The International Day of the Girl Child, a day dedicated to recognizing girls' rights to fulfill their potential and the tremendous challenges they must face to overcome the barriers of discrimination, prejudice and violence that systematically hold them back. This year’s celebration pays tribute to 25 years since the Beijing Declaration and Platform for Action, a roadmap and plan for achieving gender equality that was drafted, and adopted, by 189 Member States of the UN, meeting during The Fourth World Women Conference, held on Sept 4-15, 1995, in Beijing, China. In particular, the commemoration of The Beijing Platform  targets  the provisions of Chapter IV, Section L dedicated to the “The girl-child”.  

The theme My voice, our equal futureselected for this year’s celebration of The International Day of the Girl Child, also echoes the new UN Women campaign Generation Equality,  launched April 24-26, 2019 in Tunis, to bring together younger generations of women and men, feminists and activists fighting for gender equality. A campaign designed precisely to align younger generations with the visionaries of The 1995 Beijing Platform, for the purposes of realizing the Women’s Rights movement of an equal future, while leaving no one behind.

However, this year’s celebrations are also marred by the devastating impact of the COVID19 pandemic worldwide, and on women and young girls in particular (UN Women, COVID 19). An impact that has generally served to bring out, and intensify, structural inequalities of health, economy, security and social protection. Specifically, an impact that is estimated to have set the clocks back on small but significant economic development gains, particularly in the domain of education. Indeed 89% of the world’s children and youth were estimated out of school as of March 2020, with the transition to online education only serving to widen the divide between  lo-tech or no-tech populations on the one hand, and the tech-empowered on the other. 

Thus, significant gains in primary education for girls, and the narrowing of gender differences in secondary and tertiary education (goals #2 and #3 respectively), observed and reported in the UN Millenium Development Goals Report in 2015, are already estimated severely impacted. Likewise, UN Women also estimates that the COVID-19 pandemic will result in increased girl-child marriages for the purposes of alleviating economic strife, thus canceling small steps in the direction of protecting girls from marriages, dangerous to both their physical and mental health.

Similarly, UN Women,advocating on behalf of the Girl Child, estimates COVID 19 pandemic-related increases in (1):

  • violence directed at women and girls, variously due to security and health issues, cramped living conditions, restrictions on movement,  deserted public places and living with an abuser;
  • domestic violence, citing a 30% increase in calls, in countries such as France and Cyprus, 33% in Singapore, 25% in Argentina.
  • the COVID-19 infection rates of women healthcare workers vs male healthcare worker infection rates, for example: 75.5% female vs. 24.5% male in Spain; 69% women vs. 31% in Italy.
  • the number of maternal deaths and corollary increases in infant deaths within the year following the mother's death, already staggering prior to the pandemic since 810 women are estimated to die each day from preventable causes related to pregnancy and childbirth. An estimated COVID19-related increase in maternal deaths, arising  in part because 40% of the world population (3 billion people) do not have handwashing facilities at home with soap and water, now also deemed crucial to preventing the spread of the pandemic.
  • the economic strife of women and girls, who are generally less able to absorb the shock of economic hardship, since their position is more vulnerable prior to catastrophic events, man-made or not. Indeed, women earn less, save less, have more jobs in the informal economy, and therefore no social protection, and form the majority of single-parent households.
  • conflicts that strain, or completely wipe-out medical infrastructures, not only making it impossible to handle health crises like the COVID 19 pandemic, but also eliminating whatever might have existed to handle reproductive health. Thus, for  this reason also, maternal deaths are expected to soar, especially in countries like Yemen and Syria.
  • unpaid domestic and childcare work, with women and girls shouldering the effects of school closures and overburdened healthcare systems, resulting in more obstacles to seeking non-remote employment, and in girls permanently dropping out of school.   

Considering the above dampening of 2020 celebrations, the cautious hope is that such exacerbation and highlighting of the plight of women and girls will serve to illuminate a path to re-building better, and more sustainable, futures, where indeed the impatient voices of women and girls, calling for gender equality, will finally be heard.

Oh, patents! The Robomart™

Copyright © Françoise Herrmann

Back to robots, their expanded role within the context of the pandemic and re-opening of economies. The Robomart™ is a driverless autonomous mini-market on wheels. Already in operation, prior to the pandemic, the Robomart™ offered a mobile-driven mini-market, wherever customers ordered it to drive by. The Robomart™ was successful because it was not just saving customers time, going to the grocery store, it raised the bar on the experience of online shopping, allowing customers to see, and choose the produce they were buying, wherever they were located. Advantages that became amplified during the pandemic, when everyone was confined, and the demand for online shopping skyrocketed. 

Indeed, the Robomart™ became especially attractive, since it offered contactless delivery of produce, via a robotic operator that never got sick. As an autonomous vehicle, the Robomart™ delivery van is equipped with all the standard AI self-driving technology, such as LiDAR, radar and cameras, CAN motion-control system, robotic route-planning and obstacle-avoidance software, enabling various levels of autonomy from a human operator. 

The video below shows The Robomart™ in action. After viewing the video you might legitimately wonder how it is that the Robomart™ knows which merchandise has been selected, “checked-out”, and debited to your credit card. This question has a patented answer.


The Robomart invention recited in US20180349872 is titled One tap/command grocery ordering via self-driving mini-marts and seamless checkout-free technology. The abstract, together with the patent Figure 3, are included below.

The present disclosure generally relates to an application for obtaining groceries or other merchandise and, more particularly, a one tap/command grocery ordering via self-driving mini marts and seamless checkout-free technology. The method is implemented in a computer infrastructure having computer executable code tangibly embodied on a computer readable storage medium having programming instructions and is operable to: deploy an autonomous vehicle which carries consumer merchandise to a consumer; determine which merchandise has been taken from the autonomous vehicle by the consumer; calculate a cost for the merchandise taken from the autonomous vehicle by the consumer; and provide a receipt to the consumer for the merchandise taken from the autonomous vehicle by the consumer. [Abstract US20180349872]

 

US20180349872

The invention recites a system that advantageously combines the convenience of online delivery with the comfort of picking out produce yourself. An invention that also promises cost savings, passed on to customers, resulting from the fully automated system. The patent further discloses that an entire mini store is brought to the consumer vs. just an order of groceries. Thus, the Robomart™ is effectively able to compete with delivery bots and drones, as it offers a much larger selection of produce and groceries. 

According to the disclosure of the invention, the user taps on the Robomart™ app to dispatch the closest Robomart™ van 100, from a store, to their location. On its way, the Robomart™ van 100 will be tracked by the user. When the Robomart™ van 100 arrives, the user opens the compartment doors and selects items. A seamless check out system is invoked as tagged selections are recorded by sensors 105, on the racks, while prices and costs are displayed on a smart glass panel 110 of the van compartment doors, together with the customer’s name. Once the purchase is completed, debited using POS (Point-of-Sale) means from the user’s saved credit card, time-stamped according to the opening and closing of the van compartment doors, and processed using the Stripe platform on the backend, the Robomart™ van 100 moves on to the next customer, or to a replenishment center for refilling the racks, all of which can be tracked variously by users and managers, equipped with the Robomart™ app.

Receipt of purchased items might be itemized in various ways, depending on the embodiments of the invention. For example, items purchased might be listed, or they might include images. The information displayed on the smart glass compartment 110 might also be displayed simultaneously on the Robomart™ app.


The patent additionally recites various levels of self-driving vehicle technology i.e., radar and LIDAR; other cameras or backup Radio-Frequency Identification (RFID) systems for computation of items removed or added to shelves; other sensors (motion, proximity and infrared); modems for connectivity; a speaker for communication with the customer, and a cooling system for refrigeration. The patent further includes a description of the system architecture, as well as a description of real-time mapping, and tracking technology, the restocking depots and vehicle communications technology, and the on-demand summoning technology.
