摘要： A device and method for disclosing position of a positionable input by positioning the input over a range of positions to cause the magnitude of the directional component of a vector representing a field or force produced by a source to change from a reference magnitude or reference direction as the input is being positioned while an electric circuit that contains a sensor for sensing the directional component is changing the value of an electric signal for restoring the magnitude of the directional component being sensed by the sensor to the reference magnitude or reference direction, and using the value of the electric signal to disclose the position of the input.

摘要： An improved apparatus and method for position sensing of a medical tracker device are presented. The apparatus and method are designed to constrain, rotate, and track the position of a medical tool. To improve the position sensing of the tracker, a joint that provides two degrees of freedom may use a revolute gear pair together with a rotary sensor for angular motion sensing and a sliding/prismatic assembly together with a linear magnetic sensor for linear position sensing. Thus, the linear motion sensing and the angular motion sensing are decoupled.

摘要： This disclosure provides a method and system for extending the capability of a proximity detection system that is based on use of low frequency magnetic fields, to avoid conflicts in crowded work sites. The improvement is attained by combining the advantages of these low frequency magnetic fields with the advantages of much higher frequency, radiated (RF) signals that are controlled to be produced at the same time, concurrent with each other, in a coordinated and/or synchronous manner.

摘要： In an electromagnetic induction type absolute position measuring encoder having two or more tracks which includes: two or more rows of scale coils, each row including scale coils numerously arranged on a scale along a measuring direction so as to have a scale pitch different from that of another row; and transmitter coils and receiver coils provided on a movable grid relative to the scale in the measuring direction so as to face the scale coils, and which can measure an absolute position of the grid with respect to the scale on the basis of a flux change detected at the receiver coil via the scale coil when the transmitter coil is excited, coil lines are added to at least one side of the scale coils in the measuring direction at least in one of the tracks.

摘要： A tachometer signal conditioner circuit functions to accept a wide range of input signals and produces a digital pulse signal which indicates a gear shaft phase reference position. Tachometer input signals of either a true 1/revolution or an N/revolution signal with a single pulse or N pulses of different amplitude than the other pulses during the same shaft revolution can be used. The circuit comprises tachometer signal conditioner circuitry for amplifying and filtering the input from the tachometer, tachometer signal detector circuitry to produce digital pulses synchronous with the tachometer signal cycles and to detect the occurrence of a tachometer signal with a different amplitude during each 1/revolution or N/revolution period, a blanking signal generator which prevents tachometer signal noise from generating spurious 1/rev pulses during operation in the N/rev mode, and an output driver which produces signals to the remaining signal circuitry and to a front panel indicator lamp. One application of the circuit is to direct the distribution of balance weights in an airplane engine.
