Abstract: A channel allocation method for a communication network defines a definite purpose channel group that carries signals for definite purpose system devices, such as non-flight critical applications in an aircraft, and a public channel group that carries signals for user devices, such as wireless PDAs, phones and computers used by passengers. By pre-allocating discrete channel groups for different definite purpose system devices and by separating definite purpose channels (for definite purpose system devices) from public channels (for user devices), the invention allows wireless definite purpose system devices and wireless user devices to co-exist in the same operating environment without creating signal interference that could degrade the performance of the devices.

Abstract: A multi-user wireless communication system for use in an enclosed space includes a distributed aperture antenna having multiple apertures distributed along an outer shield of the antenna. The apertures allow radiated energy to leak from the antenna and form low-power, localized electric fields that can couple receivers to the antenna. The multiple electric fields ensure that the electric field strength is distributed evenly throughout the communication system. The low-power electric fields also reduce the likelihood of electric field leakage that may cause interference with other communication systems outside the enclosed space.

Abstract: An automotive transmission of the invention comprises a single transmission case, an anti-lockup assembly positioned within the case, a planetary gear set assembly positioned within the case and coupled directly to the anti-lockup assembly, a braking assembly positioned to apply braking force directly to the anti-lockup assembly, and a valve assembly located externally from the transmission case. An input assembly is coupled to the anti-lockup assembly proximate to the front end of the case which allows coupling of the transmission of the invention directly to a torque converter. A fluid pump is included in the input assembly. The anti-lockup assembly preferably comprises a safety sprag clutch, an inner sprag race, and an outer sprag race, with the sprag clutch positioned between the inner and outer sprag races. The planetary gear set assembly preferably comprises a conventional planetary gear set which couples directly to the outer sprag race.
