Abstract: A movement prevention system preventing undesired travel of a vehicle. A transmission gear sensor senses an out of park position of a vehicle transmission. An occupant detection system senses a presence of a driver in a driver seat of a vehicle in response to the vehicle transmission being out of the park position. A processor determines whether movement of the vehicle is likely to occur in response to a determination of the non-presence of the driver. A vehicle movement prevention device prevents movement of the vehicle in response to the processor determining whether movement of the vehicle is likely to occur.

Abstract: A movement prevention system preventing undesired travel of a vehicle. A transmission gear sensor senses an out of park position of a vehicle transmission. An occupant detection system senses a presence of a driver in a driver seat of a vehicle in response to the vehicle transmission being out of the park position. A processor determines an imminent movement of a vehicle in response to a determination of the non-presence of the driver. A vehicle movement prevention device prevents movement of the vehicle in response to the processor determining imminent movement of the vehicle. Imminent movement is identified as actual movement of the vehicle or movement of the vehicle likely to occur.

Abstract: The reproduction sound level of high priority messages such as navigation instructions, parking aid signals, and back-up warning signals is controlled based on the average ambient sound level in a vehicle. A sound level calibration table provides priority gain values for setting the programmable gain of a gain controller to ensure that messages are reproduced at a sound level which is relatively greater than ambient noise level by a predetermined target difference which is consistent for all levels of ambient noise. The target difference may be modified according to user preferences.

Abstract: A rotational sensing assembly including a ferromagnetic sensor wheel rotationally fixed to a shaft having a tooth pattern including a missing tooth. An inductive sensor is mounted adjacent the periphery of the sensor wheel and in communication with a processor. The sensor produces a generally sinusoidal signal in response to the wheel rotation, with voltage zero crossings that are time stamped by the processor. The geometry of the sensor wheel around the missing tooth location is altered to equalize the induced voltage in the sensor for fixed time intervals in order to maintain proper timing of the zero crossings in the sensor signal.

Abstract: A method for more accurately sensing the rotational position of a shaft having a toothed sensor wheel with a missing tooth is disclosed. The method includes employing an inductive sensor to produce a signal in response to the passing of the teeth on the sensor wheel. The sensor signal is altered by the geometry of the wheel about a gap formed by the missing tooth in order to correct for residual stored energy in the sensor at this location, and thus correct the signal for the timing measured by a processor in communication with the sensor.

Abstract: A seat structure capable of being manipulated between a normal seat or chair position and a bed position can be formed so that the seat bottom and the seat back are used along with a base of the seat structure as parts of a five-bar linkage system. A structure is provided on the base and on the seat bottom for controlling the movement of the seat bottom and the other parts connected to it in this linkage system as the seat bottom is moved between the seat and bed configurations. Interlocks are provided between the base and the seat bottom for preventing up or down movement of the back of the seat and the seat back when the seat structure is in the seat configuration.
