    摘要： A system and method for providing a tactile virtual reality to a user is present. The position and orientation of the user is utilized to generate a virtual reality force field. Forces are in turn generated on the user as a function of this force field. A six-axis manipulator is presented for providing a user interface to such a system. This manipulator provides a unique kinematic structure with two constant force springs which provide gravity compensation so that the manipulator effectively floats.

    摘要： A magnetic sensor comprises at least one first coil operatively coupled to a first portion of a vehicle seat and at least one magnetic sensing element operatively coupled to an interior portion. At least one first signal is operatively connected to the at least one first coil, wherein the at least one first signal is an oscillating signal. At least one second signal responsive to the at least one first signal is sensed from the at least one magnetic sensing element, and an occupant is discriminated an occupant on the vehicle seat responsive to the second signal.

    摘要： A rollover condition is detected responsive to the comparison of a figure of merit with a threshold, wherein the threshold is given generally as a function of a period of time commencing with a time of inception determined from one or both of a measure of lateral acceleration and a measure of angular velocity. The measures of lateral acceleration and angular velocity are filtered, and are compensated to remove offset errors. In one embodiment, the figure of merit comprises a measure function that incorporates a damping term and a product term. The product term comprises a force measure and a kinetic energy measure, wherein the force measure is responsive to the measure of lateral acceleration, and the kinetic energy measure is responsive to the measure of angular velocity. The product term may further comprise a potential energy measure that is responsive to a measure of roll angle.
