  • Patent number: 10150339
    Abstract: A tire pressure monitor system allows for customized configurations and a variety of intelligent alerts to increase usability and reliability over existing tire pressure monitor systems. A central receiver determines the alerts, rather than individual receivers, so that the tires can be monitored as a system rather than as individual tires. For instance, a Cross-Axle Alert is triggered when the pressure in a tire on one side of an axle is significantly greater than the pressure in a tire on an opposite side of the axle. Additional features include the use of Dynamic Reference Pressures, as opposed to static reference pressures, so that the alert parameters can be adjusted according to the current driving conditions. A robust user interface provides a user with a variety of views and screens and enables an administrator to adjust alert parameters while preventing a driver from adjusting the same parameters.

  • Patent number: 9776461
    Abstract: In a tire inflation pressure detection device, a receiver functions such that, when an ignition switch is on, power is generated by a power supply controller to set the power supply state of the receiver to one in which frame reception is enabled to detect the inflation pressure of a tire, and such that, when the IG is off, in each predetermined intermittent cycle power is generated by the power supply controller to set the power supply state of the receiver to one in which frame reception is enabled to detect the inflation pressure of the tire. A transmitter determines whether a decrease in tire inflation pressure occurs, and when the decrease occurs, the transmitter transmits frames more frequently than before the occurrence of the decrease in tire inflation pressure at a shorter frame transmission time interval than a regular transmission cycle during a high-frequency transmission period.

  • Patent number: 9738123
    Abstract: A vehicle warning includes a tire pressure monitoring device disposed in each tire of the vehicle. Each tire pressure monitoring device obtains information regarding pressure within the associated tire and communicated the tire pressure information in a wireless manner. A receiver receives the communicated tire pressure information from each tire pressure monitoring device. A processor circuit, associated with the receiver, determines if the communicated tire pressure information from at least one of the tire pressure monitoring devices is significantly less than a tire pressure determined to be safe for vehicle operation and, if so, to generate a warning signal. A body control module, upon receiving the warning signal, automatically activates the hazard lights without driver input.

    Abstract: A wireless, remote foot controller and a wireless instrument in direct communication with one another and method of operation. The remote foot controller can determine the wireless instrument in the hand of the dental professional and can determine whether the instrument is operational in an continuously variable mode or whether the instrument is operational at discrete speeds. The remote foot controller can then respond to activation by a user to provide a predetermined signal that drives the handheld unit with the appropriate signal. The remote foot controller is activated by application of pressure to the foot controller that provides tactile, sensory feedback to the user. The foot controller includes a circuit board, antenna and battery so that it is wireless. The circuit board includes communications protocol to permit the foot controller to communicate with several dental instruments.

  • Patent number: 9592710
    Abstract: In a wheel position detecting device, a receiver acquires gear information indicating a tooth position of a gear rotating in association with a corresponding wheel at a predetermined interval. In a wheel position detection, the receiver sets a variation allowance range based on the tooth position at a reception timing of a frame transmitted from a transmitter integrated to each wheel. When the tooth position of the gear at a subsequent reception timing of the frame is not within the variation allowance range, the receiver excludes the wheel corresponding to the gear from a candidate wheel. The receiver registers the wheel remaining last as the wheel to which the transmitter is integrated. The receiver performs the wheel position detection only when a wheel speed is higher than a predetermined threshold, so that the wheel position detection is performed based on an accurate tooth position.

  • Patent number: 9555671
    Abstract: In a method for determining identifiers of wheel units and positions relative to the vehicle of the wheels on which the wheel units are fitted, the vehicle is equipped with a speed sensor for each wheel and elements for transmitting at a predetermined angular position of the corresponding wheel about its axis a message including the identifier of the wheel unit. A central processing unit receives the message and information from the speed sensors. The method includes a) counting, for each identifier, of a number “nt” of receptions of the identifier, b) statistical processing of the numbers “nt” to determine candidate identifiers of a wheel unit of the vehicle, until the number of candidate identifiers at least equals the number of wheels, and c) determining that a candidate identifier is the identifier of a wheel unit if the candidate identifier meets a predetermined criterion.
