The invention relates to a dynamic signaling system of the evolution of the braking maneuver that has visual proportionality with respect to the loss of speed of the vehicle, with fixed or programmed response sensitivity of the system in each braking maneuver, which enables visual proportionality and dynamic unambiguous representation of the variation of speed of the vehicle during braking. It can be applied with advantages to any type of vehicle, with an electric or hybrid combustion engine, with manual or automatic transmission. The system can be applied to both brake lights and the third brake light (high-mount brake light) indistinctly or jointly, further reinforcing the dynamic effect of attention and the transmission of information.

Electronic device comprising an electronic circuit that receives signals from a sensor and which are processed by a microcontroller, such that if an increase or decrease of time is detected between the signals sent by the sensor, they will be interpreted as an acceleration or deceleration respectively, being activated the acceleration or deceleration lighting devices as appropriate.

A rear light unit of a vehicle is provided. The rear light unit includes an array of first light sources, arranged angularly offset along a first inner circumferential arrangement region, and an array of second light sources, arranged angularly offset at least along a second outer circumferential arrangement region concentric to the first inner circumferential arrangement region of the first light sources. The first and second light sources are made by one or more light-emitting diodes with which a light diffusing body is associated, the first light sources having a diffuser body in the form of a prismatic pinnacle, and the second light sources having a blade-shaped diffuser body along whose median axis emerges orthogonally a septum which enters the first inner circumferential arrangement region of the first light sources according to radial directions inserted between two successive light sources.

A system for implementing strobing of existing vehicle hazard lights including an interface to a vehicle wiring harness configured to receive input to an existing vehicle flasher module, and a strobing circuit that responds to an activation signal from the vehicle wiring harness that is indicative of a hazard flasher deployment event by producing an electrical output through the interface to the vehicle wiring harness that causes a strobing of existing vehicle hazard lamps.

A lighting system enables a lighting pattern to be displayed on a vehicle when the vehicle is in motion. A lighting pattern may include lights that fluctuate (with respect to luminosity) or lights that stay, that is, are solid, at the same luminosity. The length of time that a light, such as an LED lamp, is powered on may vary. Similarly, the amount of time between two adjacent lights are powered off and powered on may also vary. As such, the lighting sequence is flexible and can be customized so that all lights are not on for the same length of time and the time between two lights being powered may vary. A vehicle front alert system allows for improved perception of speed of an approaching vehicle, human, or object.

A system for implementing strobing of existing vehicle hazard lights including an interface to a vehicle wiring harness configured to receive input to an existing vehicle flasher module, and a strobing circuit that responds to an activation signal from the vehicle wiring harness that is indicative of a hazard flasher deployment event by producing an electrical output through the interface to the vehicle wiring harness that causes a strobing of existing vehicle hazard lamps.

A safety brake light module configured to energize a safety brake light of a vehicle and a method of energizing the safety brake light with the safety brake light module. The safety brake light module comprises a controller; and a power circuit communicatively coupled to the controller and adapted to be electrically coupled to the safety brake light; the controller comprising processing instructions configured to generate a safety brake light signal configured to cause the safety brake light to illuminate in an illumination pattern based thereon, wherein during a second braking event the illumination pattern only a constant portion when the time duration between a first braking event and the second braking event does not exceed the first predetermined time period.

The disclosed computer-implemented method may include tracking personal mobility vehicle batteries. In some embodiments, the method may track and maintain battery power for personal mobility vehicles to help to ensure that there are personal mobility vehicles with sufficient charge available to perform the needed transportation tasks within a dynamic transportation network. In some examples, a swappable battery for a personal mobility vehicle may communicate with a dynamic transportation management system and provide information about current and/or historical charge information. In some examples, the method may use the current state of charge and/or historical charge information to predict the performance of the battery. Based on the predicted performance, the method may predict the range of a personal mobility vehicles with the battery and/or a lifespan of the battery and make matching decisions accordingly. Various other methods, systems, and computer-readable media are also disclosed.

Light-based devices may be provided that emit light. The light-based devices may be incorporated into systems such as vehicles. The light-based devices may include light sources such as light-emitting diodes and lasers. Mirrors may be used to collimate light from the light sources. Light modulators may be used to pattern light from the light sources. The light sources may include light sources of different colors. Arrays of pixels may be used to provide dynamically varying patterns of emitted light. A light source may produce light that is diffracted by an array of diffractive elements on a window. Mechanical and electrical shutters may obscure light sources, mirrors, and light-emitting components mounted on windows.

A light for a motor vehicle includes a flat light guide with decoupling structures for light on the front side, as well as at least one light source for coupling light into the flat light guide. A graphic is arranged on the rear side of the light guide, the graphic being constructed from regions with different degrees of reflectivity and/or colors. The decoupling structures and the graphic have the same graphical pattern and are oriented in relation to one another. The at least one light source couples the light into the flat light guide on the end face.
