Abstract: A telematics control unit in a vehicle couples to a vehicle communication network bus and monitors signals on the bus that correspond to various parameters related to entertainment devices in the vehicle, such as, for examples, a radio, a telephone, and a video player. During a predetermined period, the TCU monitors the entertainment device signals and stores information represented by the signals to a memory. The TCU transmits the entertainment device signal information from the memory to a telematics operations center server operated by a telematics services provider. The TOC is configured to analyze the status of the entertainment signal information to determine various entertainment device settings in the vehicle and how they correlate with given entertainment programming, based on programs being broadcast when the TCU monitors the signal, or programs an occupant of the vehicle plays from storage media. Advertisers may obtain the information analysis and tailor advertising accordingly.

Abstract: A distributed parallel processing architecture for electronically steerable multi-element RF array antennas provides real time rapid array updates with decreased hardware cost and complexity. The array is subdivided into plural sub-arrays (each sub-array has more than one RF radiating element) and a phase shift interface electronics ("PIE") device is provided for each sub-array. Parameters specific to the RF elements within the sub-arrays are preloaded into the corresponding PIE. Pointing angle and rotational orientation parameters are broadcasted to the PIEs, which then calculate, in parallel and in a distributed processing manner, the phase shifts associated with the various elements in their corresponding sub-arrays. Linearization, phase compensation for various factors (e.g., operating frequency, measured characteristics of individual RF elements, feed line delay to individual elements, etc.
