  • Patent number: 6822562
    Abstract: A tire differentiating system (21, 121) is employed to differentiate tires (22, 24, 26, 28, 122, 124, 126, 128) in a vehicle (20, 120). Each tire includes a sensor (30, 32, 34, 36, 120, 132, 134, 136) which communicates with a receiver (38, 138). In a first example, when a tire (22, 24, 26, 28) is inflated above a high pressure threshold, a flag bit is stored in the sensor (30, 32, 34, 36) identifying the tire as a rear tire (26, 28). If a rear tire (26, 28) drops below a low pressure threshold, a warning algorithm is initiated to warn the driver. In a second example, the sensor (130, 132, 134, 136) is a transceiver with an RF detector circuit having an identification code. A RF transmitter (144, 146, 148, 150) is located proximate to each of the respective transceivers (130, 132, 134, 136). The receiver (138) sends a signal to each RF transmitter (144, 146, 148, 150) which generates a RF signal that is sent to the transceivers (130, 132, 134, 136).

  • Patent number: 6816063
    Abstract: A remote system includes a radio frequency identification (RFID) tag specifically identified by an RF identification signal. The specific RFID tag is associated with a particular remote data transfer device. When identified, the specific RFID tag changes the state of the associated remote data transfer device from a zero power state to an operational state. Limited power-capacity of a remote power supply is used solely for data transfer between the data transfer device and an administrator. Although many RFID signals may be transmitted over time to the location of many remote systems, each of which has an RFID tag, an RFID signal is only infrequently sent to a specific one of the RFID tags. Such an RFID signal is transmitted only to request a data transfer operation with the particular remote data transfer device that is associated with that specific RFID tag.

  • Patent number: 6784792
    Abstract: A method of deciding with a high reliability whether an impact with the front side of a vehicle has been caused by a pedestrian is described. Two decision criteria are formed, and only if both decision criteria are met is it decided an impact with a pedestrian has occurred. The first decision criterion is determined by the fact that the pressures or deformations measured by a sensor on the bumper and a sensor in the area of the front edge of the engine hood are compared with reference quantities typical of impact with a pedestrian. The second decision criterion is determined by the fact that the changes in velocity and/or acceleration of the vehicle caused by an impact are determined, and then the changes in velocity and/or acceleration are compared with reference quantities which are typical of impact with a pedestrian.

  • Patent number: 6778074
    Abstract: Speed limit indicators and methods for determining speed, the relevant speed limit, and displaying same make it easy for the driver of a vehicle to compare his current speed with the legal limit for the location in which he is traveling. This eliminates the need for the driver to take his eyes off the road to look for speed limit signs, thereby reducing the chance of an accident, and resolves any confusion that might exist as to what the current legal limit is. An audible warning of excessive speed reduces the amount of time the driver needs to spend examining the speedometer.

  • Patent number: 6775526
    Abstract: A modulated input signal is filtered to reduce noise. The state of the input signal controls the state of a switch. Depending upon its state, the switch connects one of two circuits to a gate. The gate receives the input signal and it passes or blocks the signal depending upon the state of the signal received from the switched circuits. When it is passing the input signal, the output of the gate is equivalent to the input signal. When it is blocking the input signal, the output of the gate is set to a default state. The default state is independent of the input signal. One of the switched circuits gradually modifies the signal provided by the gate to allow the input signal to pass through. The other switched circuit gradually modifies the signal provided to the gate to block the input signal.
