摘要： A rotary position sensor having a transmitter coil excited by a high frequency signal source. A first and second receiver coil, each having at least two oppositely wound loops, are rotatably positioned electrically 90 degrees relative to each other. The receiver coils are positioned so as to be inductively coupled with the transmitter coil while a coupler constructed of an electrically conductive material is rotatably positioned over and inductively coupled with the first and second receiver coils. The outputs from the first and second receiver coils are coupled through a high pass filter and a low pass filter, respectively, thus creating a 90° phase shift in the resultant signals. These signals are summed together and coupled as an input signal to a PWM circuit together with a signal from the transmitter coil.

摘要： A linear position sensor having a transmitter coil which generates electromagnetic radiation when excited by a source of electrical energy and wound in a first direction. A receiver coil is contained within the transmitter coil and the receiver coil includes both a first loop wound in a first direction and a second loop wound in the opposite direction. A coupler element linearly moves along a first direction relative to the transmitter coil which varies the inductive coupling between the transmitter coil and the receiver coil as a function of the linear position of the coupler element to thereby vary the electrical output signal from the receiver coil when excited by the transmitter coil. The first and second loops of the receiver coil are linearly aligned with each other along the first direction.

摘要： An emergency automotive braking system in which a vehicle brake is movable between a braking position and a non braking position. An electrically powered actuator is mechanically coupled to the vehicle brake and, when energized, moves the vehicle brake from the non braking and to the braking position. A charging circuit electrically charges a capacitor bank. A collision avoidance system generates a trigger output signal upon detection of a potential vehicle collision to a control system which, in response to the trigger signal, electrically connects the capacitor bank to the actuator to energize the actuator.

摘要： An apparatus providing a signal related to a position of a coupler element comprises an exciter coil and a receiver coil, the apparatus being operable to provide a signal correlated with the position of the coupler element using a receiver signal generated when the exciter coil is energized due to an inductive coupling between the receiver coil and the exciter coil. In some examples, the receiver coil has first and second sections generating a first section signal and a second section signal respectively, and an electronic circuit is operable to generate a position-independent signal using the first section signal and the second signal. This position-independent signal may then be subtracted from a baseline voltage to provide an improved reference signal for ratiometric position sensing.

摘要： An inductive position sensor for position sensing includes a transmitter coil and a receiver coil, the receiver coil generating a receiver signal when the transmitter coil is excited by an alternating current source. A moveable coupler element modifies the inductive coupling between the transmitter coil and the receiver coil so that the receiver signal is sensitive to the coupler element position. For example, the coupler element may rotate about a common central axis of the transmitter coil and receiving coil. In further examples, a reference coil is configured so that a provided reference signal is substantially insensitive to variations in the angular position of the coupler element. A ratio between the receiver signal and the reference signal is sensitive to the coupler element position, but substantially insensitive to common mode factors that influence the reference signal and receiver signal to a substantially equal degree.

摘要： The invention relates to a pedal pad force sensing assembly having a force sensing capacitor. The force sensing capacitor includes an upper plate which is overmolded into the pad body and a lower plate supported on the pedal arm. A sensing module includes an electronic circuitry to determine change of capacitance when pressure is placed on an upper surface of the pad. The sensing assembly may advantageously include a reference capacitor which is mounted near the sensing capacitor but not subjected to pressure.

摘要： An apparatus for determining an angular position of a shaft, such as a steering column, comprises a coil assembly, a coil support, and a coupler element having a coupler angular position correlated with the angular position of the shaft. The coil assembly includes a transmitter coil and at least one receiver coil, the coupler element modifying an inductive coupling between the transmitter coil and at least one receiver coil. A signal processing circuit receives coil signals from the coil assembly and determines the angular position using a receiver signal, and a reference signal that is correlated with an axial displacement but otherwise substantially independent of angular position. The reference signal can be used for ratiometric sensing, to substantially eliminate common mode factors, and also to determine the number of revolutions of the shaft. A combined angle and torque sensor further determines a twist angle across a torsion bar.
