Abstract: A system for providing situational awareness to a cyclist or other user of a micromobility vehicle comprises a stereo camera assembly and processing logic configured to determine, based on images acquired by the stereo camera assembly, a distance between the cyclist and an object of interest (e.g., a vehicle). The system is configured to determine a threat level of the object based one or more factors such as, e.g., a speed of the object and/or a category of the object. In some examples, the system includes a display and/or an audio indicator to convey information to the cyclist about detected threats. In some examples, the system is configured to produce an audio indication in response to a threat exceeding a threshold threat level. A software platform may be configured to store and/or process micromobility data gathered from one or more users.

Abstract: Disclosed herein is an autonomous solar panel for use in winter conditions. The panel includes at least one energy transfer member associated with the solar panel. A sensor is in communication with the energy transfer member. A power supply is connected to the energy transfer member. A network interconnects the energy transfer member, the sensor, and the power supply, and is configured so that when the sensor senses an accumulation of winter precipitation on the solar panel, a portion of stored power in the power supply activates the energy transfer member and the winter precipitation is removed from the solar panel.

Abstract: A reflective materials sensor for detecting remotely located reflective material. The reflective materials sensor includes a transparent window with two window surfaces, an amount of reflective material that is remotely located away from one window surface. An operating parameters sensor located adjacent to the transparent window, a radiation detector located away from the other window surface; and two spaced apart radiation emitters located on either side of the radiation detector, and away from the second window surface. Each radiation emitter is configured to emit radiation along one axis through the transparent window towards the reflective material and towards a common focal point. The radiation detector is located to receive reflected radiation from the reflective material along another axis. The first axis of the radiation emitters is angled towards the other axis of the reflected radiation.
