摘要： A magnetic sensor is provided which utilizes a molded magnet with a channel formed therein. A magnetically sensitive component, such as a Hall effect element, is attached to a substrate or printed circuit board. The printed circuit board, or substrate, is provided with an opening through its thickness that is shaped to accept a post with a certain amount of clearance therebetween. This allows the printed circuit board to be moved relative to the magnet during calibration procedures and then rigidly attached in a position relative to the magnet by soldering the post to the substrate or printed circuit board. This places the magnetically sensitive component at a desirable location relative to the magnet and within the channel formed in the magnet. The post can be molded into the magnet or formed as an integral portion of the magnet.

摘要： An apparatus and method for detecting gear features is provided. The apparatus includes a magnetic-sensing element, a thresholding module, and an output module. The magnetic-sensing element may provide a sensor-output signal indicative of the presence of a gear feature. The thresholding module may (i) transform the sensor-output signal into a characteristic waveform, which is also indicative of the presence of the gear feature; (ii) detect a first difference between the characteristic waveform and a reference signal, and responsively provide a tracking signal that tracks this difference; and (iii) detect a second difference between the tracking and reference signals, and responsively adjust the sensor-output signal. Adjustment may be performed (i) as a function of the second difference when it falls below a given threshold and (ii) by a predetermined amount when the second difference satisfies the given threshold. The output module may produce an output signal as a function of the characteristic waveform and the reference signals.

摘要： A first magnetic sensor is formed on a semiconductor substrate, and the first magnetic sensor produces a first output signal in response to movement of a multi-pole magnet. A second magnetic sensor is formed on the semiconductor substrate so as to be intertwined with the first magnetic sensor and so as to be at a predetermined angle with respect to the first magnetic sensor. The second magnetic sensor produces a second output signal in response to movement of the multi-pole magnet. The predetermined angle is between 0° and 180° exclusive, and the predetermined angle is sufficient to produce a difference in phase between the first and second output signals. An output signal converter converts the first and second output signals to a linear signal.

摘要： A method and system for orienting and calibrating a magnet for use with a speed sensor. A magnet can be mapped two or more planes thereof in order to locate the magnet accurately relative to one or more magnetoresistive elements maintained within a speed sensor housing. An optical location of the magnet with respect to the magnetoresistive element and the sensor housing can then be identified in response to mapping of the magnet. Thereafter, the magnet can be bonded to the speed sensor housing in order to implement a speed sensor thereof maintained by the speed sensor housing for use in speed detection operations.

摘要： An off axis geartooth sensor is provided with a center line of the sensor disposed along a line which is not coincident with the center of rotation of the rotatable member to be sensed. Instead, the center line of the housing in which a Hall Effect element is disposed is positioned at a perpendicular distance from the center of rotation of the rotatable member which is determined as the function of a range of dimensions which define the allowable gap between the Hall Effect element and a surface of the rotatable member. The perpendicular distance between the center of rotation and the line along which the proximity sensor is disposed is mathematically determined as a function of the distances between the center of rotation of the rotatable member and the minimum and maximum possible locations of the Hall Effect element along with the angular distance between those two dimensions. The present invention provides a geartooth sensor which is significantly immune to changes in the gap between a Hall Effect element and the surface of a rotatable member which is being sensed. The rotatable member is provided with a least one discontinuity in its surface which causes changes in the magnetic field surrounding a Hall Effect element and, as a result, provides a signal from the Hall Effect element to indicate the proximity of the discontinuity to the Hall Effect element.
