Abstract: A method for modifying a brightness level of an automobile vehicle backup light includes: receiving electronic signals in a brightness evaluator and light controller defining at least one image captured within a field-of-view (FOV) of an automobile vehicle camera; dividing the at least one image into multiple independent zones; evaluating an environmental brightness level of individual ones of the multiple independent zones; comparing a brightness level of at least one backup light of the automobile vehicle to the environmental brightness level; and sending a control signal to the at least one backup light to modify the brightness level of the least one backup light.

Abstract: Systems and methods for mobile platform localization for a mobile platform. The system includes three independent ultra-wideband (UWB) sensors mounted on the mobile platform and a UWB localization module operationally coupled to the first UWB sensor, the second UWB sensor, and the third UWB sensor, and programmed by programming instructions to: identify first beacon UWB transmissions from a first beacon external to the mobile platform and generate a spatial location of the first beacon; identify second beacon UWB transmissions from a second beacon external to the mobile platform and generate a spatial location of the second beacon; identify third beacon UWB transmissions from a third beacon located external to the mobile platform; and generate a spatial location of the mobile platform, as a function of the spatial location of the first beacon, the spatial location of the second beacon, and the spatial location of the third beacon.
