Abstract: A method and apparatus is disclosed herein for wireless communication with adaptive beamforming. In one embodiment, the apparatus comprises a processor, a radio frequency (RF) transmitter having a digitally controlled phased array antenna coupled to and controlled by the processor to transmit content using adaptive beamforming, and an interface to a wireless communication channel coupled to the processor to communicate antenna information relating to the use of the phased array antenna and to communicate information to facilitate playing the content at another location.

Abstract: A cabin pressure control system and method includes one or more dual-channel controllers. One of the channels is a primary channel and the other channel is a secondary channel. The primary channel includes two dissimilar cabin pressure sensors and a controller that is used to modulate the position of an outflow valve, to thereby control cabin pressure, in response to the sensed cabin pressures. The secondary channel includes a cabin pressure sensor and a differential pressure sensor that is configured to sense cabin-to-atmosphere differential pressure. The secondary channel, based the sensed differential pressure, will implement differential pressure limiting in the event the primary channel does not. The primary and secondary channels both implement a cabin altitude limit function.
