    Abstract: In many applications such as automobiles on busy highways, if a lot of vehicles on road are equipped with Doppler radars to help improve driving safety, no matter human-driven or auto-driven, if the radars use same frequency band, avoiding interference between them is a hard task. Assigning distinct frequencies is one of the solutions, however not only it wastes expensive spectrum resource, but also the task itself to dynamically assign frequency to vehicles randomly come together becomes a hard one to do. The disclosed invention of Doppler group radar will allow radar devices to work together using shared frequency band without interfering one another, without sacrificing performance, and without much increase in costs.

    Abstract: A system and method are disclosed for embedding a timing controller on column drivers which, among other advantages, reduces power consumption and size constraints. A standalone timing controller is eliminated by splitting a video input signal and delivering the signal to each of the column drivers. Timing controller functionality is embedded in each of the column drivers to allow the column drivers to process the received video signal. An auxiliary input used for communication between column drivers and an external system is received by a master column driver. The master column driver communicates with slave column drivers to enable point to point communication between each column driver and the external system.

    Abstract: A technique for controlling operation of a communication subsystem is described. The subsystem is set to a first wake-up mode of operation, during which a state value from the system is read and stored in memory. The subsystem is then set to a sleep mode of operation after the first wake-up mode of operation, and to a second wake-up mode of operation after the sleep mode of operation. The stored state value is then read from the memory, where the subsystem is set to operate based on the read state value during a warm-up period of the second wake-up mode of operation.
