摘要： A single die MR sensor having three MR elements each being preferably composed of a number of serially connected MR segments for use in linear position sensing schemes. The MR sensor is, generally, aligned in the direction of movement of a magnetic target. The middle MR element is the actual position sensor. The two outer MR elements serve as reference sensors which sense the magnetic field at the limits of the position sensing range. The cooperating magnetic target assures that one of the two outer MR elements is always exposed to some maximum magnetic field, BMAX, corresponding to a position XMAX, and the other MR element is always exposed to some minimum magnetic field, BMIN, corresponding to a position XMIN, and wherein a portion of the middle MR element is exposed to BMAX and another portion of the middle MR element is exposed to BMIN, wherein the position, X, of the target is computed assuming uniformity of the middle MR element along its length.

摘要： A method of accurately emulating any desired tooth/slot format of a desired target wheel from a predetermined tooth/slot arrangement of a rotating actual target wheel used in conjunction with an MR position sensor. The passage of two sequential slots of differing widths or two sequential teeth of differing widths of the actual target wheel determine the rising and falling edge of one tooth of the desired target wheel and define one tooth and one slot of the desired target wheel. The actual target wheel, has, preferably, 2n teeth and 2n slots of two distinct sequential widths whereby the desired target wheel is emulated to have n teeth and n slots. The two MRs of the position sensor are aligned in the circumferential direction of the actual target wheel so as to generate two angularly offset signals (first and second voltages, respectively) from the passage of a single slot of the actual target wheel. The offset signals are input to a signal conditioning circuit. Within the signal conditioning circuit, the two sensor signals (first and second voltages) are differentially amplified to produce a differential signal whereby the width of the slot is used to encode a binary position voltage, high or low. The two distinct sequential slot/tooth widths of the actual target wheel are used to identify a tooth edge of the desired target wheel as rising or falling and, hence, define the teeth and slots of the desired target wheel. Alternatively, the present invention could be implemented with width encoded teeth instead of width encoded slots.

摘要： A horizontal-mount bracket system for holding sensor position with respect to a horizontal-mount bracket, wherein facial interaction between the bracket and the sensor body provides automatic setting of the air gap which setting is preserved such that if the sensor is ever reinstalled, the air gap is precisely reset to its original value. A multi-component bracket has first and second bracket components which lay juxtaposed, one atop the other. The first bracket component has a first sensor opening and the second bracket component has a second sensor opening wherein initially the first and second sensor openings are mutually communicating and aligned just sufficiently so that the sensor body is free to vertically move therein. The sensor body is placed into a sensor port of an engine block so that the tip of the sensor body rests upon a surface of a reluctor. With the multi-component bracket resting upon a horizontal surface of the engine block, the first bracket component is laterally displaced relative to the second bracket component, causing the first and second sensor openings to be horizontally displaced relative to each other and inscribe the sensor body at an inclined angle which causes the tip to be separated from the reluctor by a predetermined air gap. Alternatively, the first and second bracket components may be inclinably slid relative to each other to thereby cause the sensor tip to be moved away from the reluctor.

摘要： A bracket and sensor body of a magnetic sensor, wherein relative rotation therebetween provides precise setting of an optimal air gap, and wherein operation is very quick, easy and reliable and wherein the air gap setting is precisely repeated each time a magnetic sensor is replaced or re-installed. In a first preferred embodiment, the bracket is provided with a sensor aperture having a predetermined shape, and at least one cutting tab is provided at the sensor aperture which has a predetermined pitch angle relative to the plane of the bracket. The sensor body is composed of a relatively softer material, such as a plastic, which is cuttable by the harder material of the one or more cutting tabs, wherein the shape of the sensor body is generally complementary to the predetermined shape of the aperture. Rotation of the sensor body relative to the bracket causes the one or more cutting tabs to cut into the sensor body. Depending upon the pitch of the at least one cutting tab relative to the plane of the bracket, the sensor body moves relative to the bracket in a direction normal to the plane of the bracket. Various structures are utilizable to prevent over rotation, resist back rotation and assure proper initial orientation of the sensor body relative to the sensor aperture.

摘要： A bracket and washer combination providing secure holding and positioning of a magnetic sensor, wherein an optimal air gap is automatically set as the washer is brought into a slot of the bracket due to facial interaction therebetween. In one embodiment, the sidewalls of the slot have teeth of predetermined pitch, while the washer has smooth sidewalls. In a second embodiment, the sidewalls of the washer have teeth of a predetermined pitch angle, while the sidewalls of the slot are smooth. The member having toothed sidewalls is formed of a material harder than the member having smooth sidewalls. The washer and slot are dimensioned so that the sidewalls of the washer tightly abut the sidewalls of the slot, wherein the teeth of the toothed sidewalls inscribe corresponding grooves into the smooth sidewalls as the washer is pressed into the slot along a transverse axis. Consequently, as the corresponding grooves are inscribed, the washer sidewalls are caused to move in relation to the slot sidewalls in a direction parallel to the pitch of the teeth, resulting in a relative movement between the washer and the bracket along a longitudinal axis. However, since the washer is affixed by a bolt so that it is constrained from moving along the longitudinal axis, the relative movement is provided by the bracket moving along the longitudinal axis in relation to the washer.

摘要： A device is provided which is capable of generating a surface that at least partially conforms to the contour of an article. The surface is defined by the ends of a number of threaded members which are supported within a suitable support structure. The threaded members are aligned so as to be substantially parallel to and threadably engaged with each other. As a result, rotation of an individual threaded member will cause that threaded member to be longitudinally moved relative to its adjacent threaded members and the support structure, without displacing an adjacent threaded member. The surface can be readily configured manually or automatically to serve as a die or mold cavity when the entire surface has been generated to conform to the entire contour of the article. Alternatively, the surface can be generated so as to provide a suitable fixture surface for supporting and securing a workpiece during a machining or welding operation. Due to its method of generation, the surface can be quickly and repeatedly reconfigured to conform to an article or workpiece having a completely different contour.
