Abstract: An automatic door system capable of distinguishing between a door closing action for when an object leaves a prescribed area, which results from a “signal discontinuation due to the exit of an object”, and a door closing action for when an object remains stationary within the area for a certain period of time, which results from a “forced signal discontinuation in the presence of a stationary object”. Regarding the latter case, the automatic door system protects a person who stops in the area by setting the door to close at a low speed and/or issuing a vocal warning. The door closing action of the automatic door system can thereby reduce the risk of hitting the person with the door.

Abstract: An apparatus (10) comprises a controller (82) for receiving a control parameter. At least one tire condition sensor (26-32) senses a tire condition and transmits a tire condition signal (34) indicative of the sensed tire condition. A receiver (78) receives the tire condition signal (34) and compares the received tire condition signal (34) to a changeable threshold to output a digital signal indicative of the received tire condition signal (34). The changeable threshold changes at time intervals determined by a time constant of the receiver (78). The time constant of the receiver (78) is variable. The controller (82) is operatively connected to the receiver (78) and varies the time constant of the receiver (78) in response to the received control parameter.

Abstract: A very reliable alarm system is comprised of transceiver node devices interconnected via infrared links forming a secure perimeter, whereby each transceiver node in the perimeter receives an infrared transmission from a previous transceiver node, and itself transmits an infrared signal to the next transceiver node in the perimeter. If a break of an infrared link occurs, such as would happen if an intruder enters the perimeter area, an indication of the break is communicated around to a base unit device either by each subsequent node device inhibiting its infrared transmission, or changing its transmission to that of a special alarm signal. Upon receiving an indication of a perimeter break the base unit device alerts alarm signaling devices such as audible or visual alarm indicators.

Abstract: A control system for estimating the tongue length of a trailer being towed by a vehicle in connection with a front wheel steering with or without a coordinated rear wheel steering associated with the vehicle. The control signal system employs an algorithm that calculates an estimated hitch angle between the vehicle and the trailer based on an estimated tongue length, a front wheel steering angle, a rear wheel steering angle, a measured hitch angle, vehicle speed and vehicle yaw rate. The estimated hitch angle is compared to the measured hitch angle to generate a hitch angle error that is converted to a tongue length error. The tongue length error is compared to the estimated tongue length to become a corrected estimated tongue length for a next computation period. After a few seconds of processing, the corrected estimated tongue length will be the actual tongue length of the trailer.

Abstract: A device for the radio-transmission of a hazard warning to the driver of a motor vehicle includes a data transmission device for transmitting and receiving data. The data transmission device exchanges data with data transmission devices of other motor vehicles, including data to warn other motor vehicles of the hazard, evaluates received data and outputs warning signals to the driver when a hazard is detected. The transmitted data includes information on the position, speed and direction of travel of the transmitting motor vehicle, as well as the type of road on which the transmitting motor vehicle is moving. The information on the position, the type of road and the direction of travel is generated by a navigation system. A warning zone around the current position of the transmitting vehicle is calculated by a computer unit and emitted by means of the data transmission device.

Abstract: A method and a fire-alarm system controls stationary fire-extinguishing systems. The fire-alarm devices of the fire-alarm system are equipped with one or more detectors. If at least one pre-adjustable alarm threshold of a fire identification characteristic is reached, the fire-extinguishing device is activated and the fire detectors are selectively switched to a higher stage of sensitivity. The detectors to be switched are locally selected depending on the actual development of the fire in terms of space. The dynamic adaptation of the sensitivity of the detectors to the development of a fire permits analyzing the development of the fire through the generated smoke, water vapor or extinguishing-water mist, and to influence the fire-extinction process in a targeted manner.

Abstract: A meteorological information system useable by aircraft pilots and others. A receiver-calculator unit receives raw meteorological data and site-specific physical data from a ground-based weather station having a signal transmitter for broadcasting signals conveying data about weather conditions at the station. The transmitted raw data signals are received by the receiver-calculator unit in the aircraft. The receiver-calculator unit may feature an input with which the operator inputs information about the physical character, such as the heading, of the runway of interest. The receiver-calculator unit processes both received raw weather data and received site-specific physical data, and/or operator-input data, to derive additional meteorological information. The raw and derived weather conditions information is displayed by the unit to be available to the aircraft pilot during landing or take-off maneuvers.
