Abstract: A communications device is provided for permitting internet access on an aircraft. A first computer on the aircraft is in communication with the communications device. A second computer on the aircraft is also in communication with the same communications device. Access to the first computer is provided to a passenger. Access to the second computer is provided to a second person. The passenger is prevented from obtaining access to the second computer.

Abstract: Systems and methods for defining information provided by aircraft are provided. An exemplary method, involving an aircraft that is operative to provide information in a first report format, includes: communicating information corresponding to a second report format definition to the aircraft, wherein the information corresponding to the second report format definition is received at the aircraft via wireless communication; and receiving, from the aircraft, information complying with the second report format definition.

Abstract: Electronic circuitry is disclosed for interfacing with a plurality of two-position switches to determine if each switch is opened, closed or faulty to some extent. Each switch is connectable in series with a pull-up resistor and between two different voltage values. The switch provides an output voltage at the connection of one terminal of the switch with the pull-up resistor. This switch voltage is presented to both an inverting input of a first comparator and a non-inverting input of a second comparator. The non-inverting input of the first comparator has a reference voltage of a certain value applied thereto, while the inverting input of the second comparator has a reference voltage of a certain value also applied thereto, the reference voltage values being different so as to define a "window" or "dead band" region of voltage. The switch output voltage is compared to the reference voltages on the two comparators. If the switch is closed, the comparator outputs will assume certain states.

Abstract: This invention relates to a heat reclaiming device for a heat pump. The heat reclaimer is able to absorb heat from the compressor by circulating cooling fluid through a circuit which is mounted in good heat transfer relationship with the condenser, then around the shell of the motor-compressor and lastly around the hollow tube which connects the condenser to the compressor. The reclaiming circuit is connected into a fluid circulating loop which is used to supply heat to the evaporator coil of the heat pump.

Abstract: This disclosure relates to an apparatus for controlling the rate of heat transfer of one of the heat exchange coils in a heat pump installation.
