Abstract: A method of providing visual data to a pilot in an aircraft cockpit includes receiving information in the form of a voice signal, converting the information to visual data, and displaying the visual data to the pilot in the aircraft cockpit.

Abstract: Disclosed is a system and method for compensating for the effects of aging and temperature on the performance of transistors in an RF transmitter. The system and method use a temperature-based polynomial and a feedback control loop to correlate the drain current of each transistor with the desired performance characteristics of each transistor. The present invention measures drain current and temperature of the transistor; compares the measured drain current with the desired drain current, which corresponds to the desired performance characteristics; computes a transistor bias voltage based on the temperature and a control parameter, wherein the control parameter is adjustable based on the measured drain current; and applies the bias voltage to the transistor. The process may be repeated, with the control parameter adjusted with each iteration, until the desired drain current is reached.

Abstract: An audio system may comprise a transceiver configured to receive, detect, and transmit audio signals on a first channel frequency and to receive and detect audio signals on at least one additional channel frequency. The at least one additional channel frequency may include a second channel frequency. The system may include a controller configured to output a first audio cue while outputting audio signals received from the at least one additional channel frequency, to output a second audio cue at a time when the controller begins outputting an audio signal received from the first channel frequency, and to output a third audio cue at a time when the controller begins outputting an audio signal received from the second channel frequency. The first, second, and third audio cues may be different from one another.

Also included is an analog to digital converter operable to convert the analog signal to a digital signal, and a digital processing system operable to process the digital signal and simultaneously generate one or more output signals corresponding to at least one of the plurality of channels within the frequency band. Various exemplary embodiments of the radio receiver and associated method are provided.

Abstract: An ice-cream container pack that forms a replaceable cartridge in an associated dispensing machine, said pack comprising a cylindrical body fitted with a nozzle and a plunger which, when operated by the piston of said machine, dispenses the ice cream from the pack via said nozzle, said pack being characterized in that the bottom edge (8) of the cylindrical body wall (1) is directly attached to the end wall (5), said end wall being in the form of a truncated cone, the smaller and free base of which houses the extrusion nozzle (7), whereby a part of the end wall (5) constitutes the support base for the pack on the support (4?) with which said dispensing machine is provided.

Abstract: A frozen aerated product in a container, the container having a wall delimiting a cavity and having an opening, the cavity containing a bag, the opening being closed by a valve having a product inlet and a product outlet, the bag containing the product inlet, the cavity containing a propellant, the frozen aerated product being contained within the bag and gastightly separated from the propellant by the bag, there being an annular hermetic seal between the bag and the wall; characterised in that the bag is resiliently inflatable and the frozen aerated product is under a gauge pressure of between 4 and 18 bar.

Abstract: A system for information transmission having a plasma antenna, including an electrodeless plasma tube, and a power source effective to generate an electromagnetic field to cause ionization of material within the tube so as to form the antenna for one or both of either sending or receiving signals, wherein the electromagnetic field is applied to a portion only of the tube. The system preferably includes a terminal arranged about a base of the tube or establishing the electromagnetic field upon application of power from the power source, to induce surface wave ionization within the tube.
