Oh, patents! Pedestrian-safety signpost

 Copyright © Françoise Herrmann

Invented by a former paramedic, with experience responding to more than one emergency involving a pedestrian at a crosswalk, the JLS pedestrian safety signpost is precisely designed to prevent crosswalk accidents. The JLS signpost uses infrared sensors to detect the presence of humans and animals via temperature, which in turn triggers means of signaling pedestrians to traffic, using flashing lights and lighting of a pedestrian sign, as well as active video recording of the crosswalk. Infrared sensors are used to make sure that falling leaves and insects do not trigger the signaling system.

The JLS pedestrian safety signpost invention is recited in the European patent application, EP3886077A1, titled System and method for detecting and signaling use of a pedestrian crossing, and filed on March 3, 2021. The inventor, Jérôme Saez, hails from the Southeast of France. The European patent application was filed in French, one of the three official languages of the European Patent Organization. The original French title of this pedestrian safety invention is Système et procédé pour la détection et le signalement de l’engagement d’un passage piéton.

Below, the patent Figure 1, together with an image of the marketed pedestrian safety signpost. The patent Figure 1 depicts a pedestrian detection and signaling system (1) at a crosswalk (2), with an “obstacle” (3). The "obstacle" (3) is shown in this case as a pedestrian, but otherwise could also be an animal. The patent Figure 1 also shows electric power supply means (7), comprising photovoltaic (PV) panels (19), and an undepicted accumulator (17), or a wired electrical supply in other embodiments of the invention. The patent Figure 1 also depicts an always-on, obstacle (3) detection module (5), preferably infrared so that human and animal temperature might be detected, although other sonar, radar, visual and analog detection devices might also be used. Finally, the patent Figure 1 also comprises signaling means (9) to alert road users to the presence of a pedestrian. The signaling means comprise strips of electroluminescent (LED) lights (12), so that the signpost (11) might become visible. Low lighting means (10), illuminating the crosswalk (2) and sidewalk, are also shown. Camera recording means are undepicted.




The translated abstract of the invention is included below.
The invention relates to a method for detecting and signaling presence of an obstacle on a pedestrian crossing (2) and its implementation system, comprising the following steps:
- S1: detecting the presence of an obstacle at the pedestrian crossing, and its immediate environment via a module for detecting the presence (5) of an obstacle (3);
-S12: Measuring the temperature of the obstacle (3) in the zone of the pedestrian crossing (2) thus detected;
- S13: determining the nature of the obstacle (3) based on temperature, using a table of known value ranges characteristic of potential obstacles;
-S14: If the measured temperature corresponds to the temperature range of a type of obstacle to be signaled, implementing the steps comprising:
S2: signaling to road users the presence of an obstacle on the pedestrian crossing via the activation of signaling means (9), comprising the activation of a low lighting element (10), suitable for illuminating the roadway and the pedestrian crossing (2), and at least one other signaling element (9) intended for road users;
S3: Activating a video recording of the pedestrian crossing and the immediate environment of the pedestrian crossing, as soon as the presence of an obstacle is detected on the pedestrian crossing via a camera (25). [Abstract EP3866077A1]
