    摘要： A traffic control preemption system uses data received from a global positioning system (GPS) to determine whether a vehicle issuing a preemption request is within an allowed approach of an intersection. GPS signals are received and processed by the vehicle module to generate vehicle data, including the vehicle's position, heading and velocity. The vehicle data is transmitted via radio transmission or some other medium. Each intersection has an associated intersection module which, if within range of the vehicle's transmitting equipment, compares the received vehicle data with a preprogrammed map of allowed approaches to the intersection. If the vehicle data sufficiently matches the map of allowed approaches, the vehicle's preemption request is forwarded to the intersection controller to appropriately control the phase of the traffic signal at the intersection.

    摘要： A secure optical-communication traffic-preemption system and method is provided that securely communicates an identification code from an optical emitter to a traffic location. The optical emitter transmits light pulses that represent an encrypted code that is an encryption using a time-varying encryption key of at least an identification code. An optical detector situated at a traffic location receives the transmitted light pulses. Validation, including decryption using a time-varying decryption key, is attempted for the encrypted identification code represented within the received light pulses. In response to validating the included identification code, a traffic-preemption command is generated for a traffic light at the traffic location.

    摘要： A remotely-activated vehicle priority system includes a control center, a vehicle-priority communication device, at least one receiver, and a phase selector. The control center transmits an activation message. The vehicle-priority communication device is mounted to a vehicle and is communicatively coupled to the control center. In response to the activation message, the vehicle-priority communication device transmits a priority preemption request. Transmission of the priority preemption request in response to the activation message prevents improper activation, either intentional or unintentional, of the vehicle priority system by an operator of the vehicle. The receiver is situated at a traffic signal and receives the priority preemption request. The phase selector issues, responsive to the priority preemption request, a command to a controller of the traffic signal. The command selects a phase for the traffic signal.

    摘要： An automatic video cassette recorder cleaning cartridge includes an enclosed cleaning fluid aerosol cannister actuated via a solenoid and lever in order to release cleaning fluid onto a cleaning tape. Actuation of the solenoid follows from detection of the rotation of the pay-out spool, which includes a camming surface operative upon a momentary switch. A shift register is included to count the revolutions of the pay-out spool and to sound an alarm when a predetermined number of rotations are sensed, whereby the cleaning of the various heads and components of a VCR is accomplished by inserting the cleaner into the VCR and operating in play mode.

    摘要： A traffic-preemption system and method that communicates an identification code from vehicles to a traffic location. Traffic light control equipment, such as a receiver and traffic light circuit at each intersection of a controlled area, is used to manage headway in mass-transit systems as well as to provide traffic light pre-emption for emergency vehicles. Each traffic light circuit in the controlled area has a receiver located at a traffic location and adapted to receive an identification code from a mass-transit vehicle. A decoding circuit responds to the received identification code by attempting to identify the mass-transit vehicle and determine the timing on the identified route that improves an identified vehicle's headway and/or route timing. In response to determining the timing, a traffic-preemption command is generated for a traffic light on the identified route.

    摘要： A remotely-controlled traffic-preemption system and method includes an encoder circuit, an optical source, an optical detector, and a decoder circuit. The encoder circuit is adapted to generate a set of signal pulses. At least one bit of a data word is encoded as a function of amplitude modulation of a first subset of the set of signal pulses and at least another bit of the data word is encoded as a function of frequency modulation of a second subset of the set of signal pulses. The optical source is adapted to transmit a set of light pulses having a respective light pulse for each signal pulse of the set of signal pulses. The optical detector is adapted to receive the set of light pulses. The decoder circuit is adapted to generate the data word from the set of light pulses received at the optical detector.
