Abstract: A vehicular “black box” provides recording means by which driver action can be reviewed after an accident or collision, as well as indicating immediate vehicle disposition status to the driver. Using cameras (which may be very small), the disposition of the vehicle in its lane is determined by detecting the highway lines painted on the road. The data is also recorded so that should an accident or collision occur, the events leading up to such an event are made available for later review and analysis.

Abstract: A monitoring and warning system for firefighters and other people exposed to similar hazards includes mutiple monitoring, warning and control devices (1, 9 through 16) and a telemetric module (17) for transmitting information data to a base station and for receiving commands. All units of the system are connected seperately to a common—open-type or closed-type—bus (8) and configured either for master-slave or for master-master operation. The system operates on simple and efficient connections, more units can be added easily, it is fast and faultless and can also be used in areas subject to explosion hazards.

Abstract: An object tracking system is constructed by linking a plurality of devices. Each device includes an RF transceiver, memory, a user interface and a processor for coordination and management of these components. The devices are programmed to form a link with another compatible device by wirelessly exchanging their unique ID codes for storage in the other's memory. The devices are responsive to messages from each device whose ID is stored in memory. Responses may range from sounding an alarm to actuation of a switch to detection of the presence or absence of another linked device. The simple, linkable devices, permit construction of complex and flexible networks for the purposes of object tracking, proximity detection, remote actuation and more. Each of the operations including linking, unlinking and general action is initiated by a single key of the device.

Abstract: An electronic tire maintenance system is provided for measuring a parameter of a device at a first location. The system includes a sensor for measuring the device parameter and generating a data signal representing the measured parameter. The system also includes a microprocessor coupled to the sensor for activating the sensor on a first periodic basis to measure the device parameter. The microprocessor includes a memory for storing the generated data signal representing the measured parameter. A transmitter and a receiver are coupled to the microprocessor. The microprocessor periodically partially awakens to determine, on a second periodic basis, if a received transmission is a valid interrogation signal and, if so, fully awakens and responds to the valid interrogation signal, via the transmitter, by at least transmitting the last stored measured parameter.

Abstract: Provided is a tire air pressure monitoring system capable of grasping the tire positions where there are sensor units even in the case of tire rotation. In the tire air pressure monitoring system, a trigger signal is transmitted from a transmission coil antenna to only the corresponding sensor unit in a manner such that a magnetic field is used as a medium and, upon receipt of the trigger signal, the sensor unit measures a tire air pressure and others and transmits a transmission signal including the measurement values to a monitoring unit. The monitoring unit makes a decision on the tire position where there is the sensor unit on the basis of the transmission signal from the sensor unit.

Abstract: A free flight obstacle avoidance system (OAS) is a commanded obstacle resolution feedback system. The system employs insertion of hybridized elements to the existing designs of Adaptive Ground Collision Avoidance Systems and Midair Collision Avoidance Systems along with a newly design module, the obstacle avoidance dispatcher and resolver, to provide a coherent obstacle resolution. The system is capable of filtering data produced by the hybrid ground collision avoidance module and the hybrid air collision avoidance module, inserting evaluating solution status and command directives before routing avoidance data to hybrid modules for validation. The dispatcher and resolver module determines the final obstacle resolution to generate avoidance control guidance and appropriate warnings clearly indicated obstacle situation and obstacle avoidance maneuvers to the flight crew.

Abstract: A system is disclosed that determines a spatial position of a tracker device relative to an object sending a return signal to the tracker. Such a system advantageously maintains phase accuracy between a forward signal from the tracker device and the return signal generator from the object. The system can include, as part of a tracker device, a reference signal generator, a transmitter, a receiver, and a spatial position computer. The reference signal generator is responsive to and phase-stabilized by a broadcast signal, e.g., a signal received from a commercial AM broadcast transmitter. The transmitter and receiver are both coupled to and phase-stabilized by the tracker reference signal generator. Variations and methods with different advantageous features are also described.

Abstract: A vehicle antenna system incorporated into at least one side-view mirror of a vehicle includes a forward directed antenna and a rearward directed antenna to transmit and receive signals over corresponding forward and rearward-directed detection fields, respectively. The antennas act as directional transmitters and/or receivers, and a processing circuit discriminates between signals from different antennas without requiring any of the antennas to transmit identification signals to the processing circuit. Signal discrimination is conducted in part by sequentially selecting each antenna to obtain a corresponding antenna signal and, if required for a particular application, comparing the obtained signal with previously obtained antenna signals. The vehicle antenna system can be used, for example, in conjunction with tire pressure sensors to detect low tire pressure in a particular tire.

Abstract: A seat belt alarm, for use with an existing seat belt having a tongue having a tongue flange extending laterally outward, and a buckle having a buckle housing, a front face having a slot for accepting the tongue and locking the tongue therein. The seat belt alarm has an L-shaped housing that selectively attaches beneath the buckle housing and extends alongside the buckle housing. When the L-shaped housing is so positioned, a plunger extends forwardly alongside the buckle housing so that when the tongue is within the slot the tongue flange keeps the plunger inward. If the seat belt is suddenly released and the tongue flange moves away from the front face, a switch in cooperation with the plunger triggers an audible warning.

Utilization of varying strength transceiver signaling between the master and slave permits the distance between the master and slave to be approximated. Additionally, the slave may contain an optional heartbeat monitor to detect and report situations in which the device is removed from the potential abduction victim.
