Abstract: A system for controlling display and operation of simultaneous transmissions of at least two media includes an entertainment unit capable of transmitting at least two media simultaneously. A wireless interface device is used to select a first and second media from the at least two media. A display device in electrical communication with the entertainment unit receives and displays a video portion associated with each of the first and second selected media. At least two wireless receivers are provided for receiving an audio portion associated with each of the first and second media. The wireless interface device is further provided for independently controlling operation of each of the first and second media.

Abstract: A system controls vehicle based communication devices that are connected to an electrical bus. A control module controls the communication devices based on the status of an access control device. The control module can use a privilege data store to determine the communication privileges a user is allowed for a particular status of the access control device. The control module can either completely or partially disable access to selected functions of communication devices based on the status of the access control device.

Abstract: A hybrid method of reprogramming the memory of an electronic module initializes the module and prepares it for the capability to subsequently receive information via high speed wireless transmission by initially down-loading to the module memory via a relatively low speed wire bus, a boot loader program and an operating system kernel. Subsequently, the remaining module memory is reprogrammed, or flashed by wirelessly transmitting new memory information in accordance with wireless protocol information passed to the module by the wire bus.
