Abstract: A plurality of radar units is included in an overall radar module such that the plurality of radar units effectively cooperates to provide an approximately 360-degree field-of-view over a relatively long range. The overall radar module may include a ring-shaped printed circuit board, and a rim that includes multiple radar units positioned to substantially cover a 360-degree field-of-view. Radar units of the overall radar module may be grouped together such that two or more radar units may operate substantially synchronously, e.g., as a substantially single radar unit.

Abstract: A roof cap assembly for a fuel cell system includes a housing, and a cover assembly disposed on the housing and configured to move between a first position and a second position. The cover assembly includes a cover including a first opening and a second opening, and a door connected to the cover and configured to selectively open and close the second opening. When the cover assembly is in the first position, the door closes the second opening, such that the reaction exhaust and the cabinet exhaust are directed through the first opening. When the cover assembly is in the second position, the door opens the second opening, such that the cabinet exhaust is directed through first opening and the reaction exhaust is directed through the second opening.

Abstract: A digital license plate with an associated payment and information handling system allowing for automated payment for pumped fuel is disclosed. The system receives data through a short-range receiver connected to a digital license plate attached to a vehicle, with the data including a defined identifier provided by a short-range beacon associated with a fuel pump.

Abstract: Vehicle mounted exterior displays and digital license plates able to operate over a wide temperature range are disclosed. In one embodiment, heat relevant display parameters can be modified as critical low temperatures are approached. If decreasing temperature is determined to be likely to interfere with display switching operation, legally required information is displayed and potentially interfering content is eliminated.

Abstract: Digital license plates having a range of physical and digital antitheft features are disclosed. Disengagement of the digital license plate from the vehicle triggers at least one of a wireless theft communication signal and the internal theft status indicator. Input of security credentials can prevent triggering the internal theft status indicator and disablement of the digital license plate.

Abstract: An air-cooled electronics module is disclosed. The air-cooled electronics module includes a housing and a heat exchanger disposed within the housing and separating the housing into a first portion and a second portion. The air-cooled electronics module also includes one or more electronic components disposed within the first portion, and one or more additional electronic components disposed within the second portion. The air-cooled electronics module further includes at least one fan configured to blow air into the second portion. The air in the first portion is substantially stagnant.
