Abstract: In a network surveillance unit, a video input unit inputs image information output from a video output device such as a camera or a switcher. A coded image storage unit codes and accumulates the image information. An alarm management unit detects the presence or absence of alarm generation from an alarm generating device, and stores the alarm information. A communication unit receives a request from a display terminal through a network, and transmits the coded image accumulated in the coded image storage unit or the alarm information accumulated in the alarm management unit according to the request.

Abstract: Brush failure detection on a robotic device for use with a data storage library is accomplished through the use of two brushes drawing power from the same conductor. For example, each brush conducts electrical current between the robotic device and a conductor. Electronics determine operating status of each brush based on a measurement of the difference in current conducted through each brush in the pair of brushes.

Abstract: An integrated cabin pressure control system valve that uses a dual, redundant channel electronic control unit for both control of the valve and to supply alarm, indication, and control signals to the aircraft's avionics system. Each channel in the electronic control unit includes an instrumentation and control circuit that uses multiple, dissimilar sensors and signals for warnings, indications, and controls. This configuration reduces the likelihood for a common mode failure that could result in a postulated gradual decompression without indication event.

Abstract: An identification (ID) tag includes a substrate having an input capable of receiving a high frequency signal. For instance, the high frequency signal can be a radio frequency (RF) signal that is generated as part of a radio frequency (RF) ID system. A first charge pump is coupled to the input and is configured to convert the high frequency signal to a substantially direct current (DC) voltage. A data recovery circuit is coupled to the input and is capable of recovering data from the high frequency signal. A back scatter switch is coupled to the input and is capable of modifying an impedance of the input, responsive to a control signal. A state machine is disposed on the substrate and is responsive to the data recovered by the second charge pump, where the state machine is capable of generating the control signal for the back scatter switch in response to the data.

Abstract: An airport feature display system for aircraft provides visual guidance cues and awareness to track the specified taxi path on a HUD. The guidance cues include symbology representative of the position of selected airport features such as runway and taxiway edges, taxi routes, and airport signage. Data representative of the airport features is communicated between aircraft systems using a data interchange method that facilitates efficient throughput of the large quantities of data required to represent the airport features.

Abstract: Tamper detection and prevention for an object control and tracking system and particularly a key tracking system is provided. Where objects being tracked are keys, a key card having a touch memory device, RF id tag, or other circuitry for storing and transmitting an ID to a controller is provided. A tether attaches a key to the card. In one embodiment, the tether is conductive and the transmission of the ID code passes through the tether. If the tether is cut, transmission is interrupted to indicate a tampering condition. In another embodiment, the tether is resistive and circuitry is provided to monitor a voltage drop across the tether. A change in the voltage drop indicates a tampering condition. An object of the invention is to detect an attempt to remove the key (or other object) from its ID card while leaving the card intact.

Abstract: The power line communication system includes a transmitter and a receiver, both providing a communication path between two communication control devices over a power line. The transmitter includes a voltage amplifier and a current amplifier. A switch between the transmit and receive modes is implemented within the voltage amplifier. The current amplifier also has a two-step output impedance. When the transmitter is active, the current amplifier shows a low impedance on the line to overcome other loads. If, however, the communication medium shows a high level of noise, the output impedance of the current amplifier decreases even further and creates a path to ground. The receiver advantageously uses a logarithmic amplifier for signal range compression. This type of amplifier preserves the shape of the signal that is important when the modulation scheme uses the zero crossings to store information.
