  • Device and method for extending the lifetime of a battery in a tire pressure sensor
    Patent number: 7259684
    Abstract: A device and method for extending the lifetime of a battery of a tire pressure sensor disposed in a tire are described, in which the battery can be recharged through the valve stem of the tire. The device includes an electrical power source and an electrode adapted to be coupled to the valve stem and supply power from the electrical power source to the valve stem.

  • Method to prevent odometer fraud
    Patent number: 6980923
    Abstract: A system and method to prevent odometer fraud in a vehicle are described, including determining whether the vehicle is driven for a predetermined period of time, such as an hour, and checking whether input to the odometer is consistent with such determination. For example, if an insufficient number of vehicle speed pulses have been received during the period of time that the vehicle has been driven, then it can be concluded that the vehicle speed pulse input has been removed from the odometer and various fraud prevention actions can be taken, such as changing the odometer display to output “ERROR” or disabling the odometer from working, even after the vehicle speed pulse input is reconnected to the odometer.

  • Logic for outside temperature display
    Patent number: 6665629
    Abstract: A method for controlling an automobile exterior temperature display during a first period of time following starting the automobile includes comparing an ambient temperature to a display temperature and comparing a speed of the automobile to a threshold speed. If the speed is above the threshold speed and the sensed ambient temperature is more than a predetermined amount above the displayed temperature, the displayed temperature is adjusted at a first rate. The comparisons are continued for a predetermined period of time and, following the predetermined period of time, the displayed temperature is permitted to increase at a second rate. The second rate of increase is slower than the first rate of increase.
