Method and apparatus for providing an aircraft emergency safety control system

Abstract: A method and apparatus for providing an Aircraft Emergency Safety Control System (AESCS) capable of regaining control of an aircraft that may have been lost due to incapacitation of the crew includes an airborne segment, a ground segment, and a communications segment wherein control of the aircraft is removed from the control of unauthorized person(s) onboard the aircraft, and the aircraft is directed to a destination that is considered a safe location for the aircraft given it's status, and to facilitate a reasonably safe emergency landing.

Configurable logic gate array

Abstract: An integrated circuit having an array of logic gates adapted to provide predetermined logic functions on a plurality of input logic signals fed to the gate array and produce such predetermined logic functions as output signals at a plurality of array output terminals. A plurality of output buffer circuits are coupled between the outputs of an interconnected gate and the array output terminals. A circuit is provided for electrically decoupling each one of the plurality of logic output buffer circuits from the plurality of array output terminals in response to a common control signal. In a preferred embodiment, the control signal is fed to a single one of the plurality of array output terminals. With such arrangement, in response to the control signal, all logic outputs of the gate array are electrically isolated from other components wired to the gate array thereby allowing diagnostic testing of these other components in spite of the fact that they are wired to the gate array. It also allows parametric testing of three-state condition of the buffers required to be three-state buffers by the customer for normal device operation.

Stand-alone biometric identification system

Abstract: A distributed biometric identification system incorporates stand-alone workstations. The system generally includes a plurality of stand-alone workstations capable of communicating with a central server remotely located from the workstations. The workstations receive input biometric data, such as fingerprint and photographic data, and compares that data to biometric data stored in the workstation. The workstation compares the input biometric data with stored biometric data to determine whether any of the stored biometric data matches the input biometric data. The results of the comparison are provided to the workstation screen. Workstation mobility is improved by housing the workstation in a self-contained, compartmentalized carrying case. Workstation mobility may be even further enhanced by housing the workstation in a so-called lunchbox configuration having a main body, a front panel hinged to the main body, and a back panel hinged to the main body. The front and back panels each have a stowed position adjacent the main body, and a deployed position away from the main body. When the panels are in their stowed positions, the workstation (i.e., main body, front panel, and back panel) is a compact, portable unit.

Phased power switching system for scanning antenna array

Abstract: A system for a phased array antenna including a set of power amplifiers for amplifying the power of a signal to be transmitted by radiating elements of the antenna. A set of hybrid couplers are connected between the power amplifiers and the radiating elements with individual ones of the hybrid couplers being cross-connected for sharing the power of each amplifier among a set of radiating elements. The coupling of power is selectively varied between the amplifiers and the radiating elements by shifting the phase of the signal applied to each power amplifier.
