Abstract: A radar scan conversion protocol is defined to communicate radar data from application servers to thin clients with reduced network bandwidth requirements. The radar scan conversion protocol may be implemented as an extension to existing thin client protocols. The system is also capable of transmitting audio and video data through the application servers to the thin clients using appropriate compressed formats in order to minimize network bandwidth requirements.

Abstract: A functional gear checking machine for determining a number of gear characteristics from a composite input signal received from a linear voltage differential transformer is disclosed. The signal from the sensing transformer is coupled to a demodulation circuit which, in turn, is coupled to several type of signal processing circuits, each of which contains a memory, and each of which processes and separates the components of the composite signals in order to provide output signals that are indicative of the desired gear characteristics. The output signals that are developed are a function of the voltage between two reference levels, at least one of which is established by the associated signal processing circuit.

Abstract: A pair of gears, which form a gear set, are tested by mounting the gears on parallel axis spindles which are located at a fixed center distance. One of the parallel axis spindles is contained in a spindle housing that is rigidly mounted to a massive base. The other gear of the set is contained in a spindle housing which is supported on top of a pair of parallel leaf springs that are connected to the base. The spindle in the spindle housing that is rigidly mounted on the base carries a pulley at its end that is remote from the gear set which is coupled through a drive belt and a second pulley to a drive motor. The spindle in the resiliently mounted spindle housing on the leaf springs is coupled to an eddy current brake at its end which is remote from the gear set. An accelerometer, which is coupled to a conventional electronic output indicator, is mounted on the resiliently mounted spindle to provide indications of the vibrations caused by the gear sets.

Abstract: A temperature-responsive electrical switch is provided which has a pair of axial leads, one of which is connected to the cylindrically-shaped electrically conductive housing, and the other of which passes through an insulator into the interior of the housing. A cylindrical-shaped, slideable electrical contact which is open at one end is positioned in the housing. A coil spring is located inside the slideable contact between the bottom end of the contact and an enlarged section of the insulator. The contact has a plurality of spring fingers which are integrally formed from the bottom of the contact and which project upwardly from the bottom of the contact toward the head of the insulated lead. A thermally-sensitive pellet, which melts at a predetermined temperature and is formed to have a cavity in it, is positioned below the spring fingers. The pellet is dimensioned transversely so as to force the fingers into contact with the head of the insulated lead.
