摘要： An electronic device has an orientation sensing system for determining an orientation of the device. The system includes a magnetometer and an accelerometer. The system further has a calibration device configured to calibrate the sensing system for operational use. The accelerometer supplies measurements used to constrain a range of possible directions of the external magnetic field to be determined. The calibration device numerically solves a set of equations and is equally usable for a 2D or 3D magnetometer in combination with a 2D or 3D accelerometer.

摘要： A non volatile memory device comprises memory cells such as MRAM cells, reading circuits and a reference cell for generating a reference for use by the reading circuits, and can determine if the reference is degraded by thermal instability. This can help reduce a data error rate. Detecting such degradation can prove to be more effective than trying to design in enough margins for the lifetime of the device. The reference cell can be less susceptible to degradation than other cells by using different shape of cells and different write currents. Where each reference cell is used by many memory cells, the reference cell tends to be used more often than any particular memory cell and so can be more susceptible to degradation. Another way of ensuring against longer term degradation of the reference is periodically rewriting the reference cell.

摘要： Reference magnetic elements or bits with a range of magnetic volumes smaller than the minimum size used for actual data storage are written or patterned in the data storage device. The reference elements or bits have dimensions such that their magnetization will relax in a shorter time than that of the minimum expected relaxation time of the storage elements or bits. Probing of the magnetization of the reference elements or bits allows the detection of the probable onset of magnetization relaxation in the storage elements or bits therefore signaling that the re-writing (re-magnetizing) of the storage elements or bits is necessary. Such a scheme can be organized over rows, columns, or sectors.

摘要： A sensor for sensing magnetic field strength has a sensor element, and detection circuitry for detecting a level of resistance of the sensor element, the level of resistance varying with magnetic field under test and having hysteresis, so that upon electromagnetic excitation the resistance can switch between two or more stable levels as the magnetic field under test varies. The sensor outputs a digital signal according to the level of resistance. The sensor output may further be interpreted in terms of a change-of-state upon electromagnetic excitation. As the sensor no longer needs a different characteristic from magnetic memory cells, it can be much easier to construct and to integrate with magnetic memory cells than an analog sensor. An excitation signal varies a threshold for the magnetic field under test at which the resistance switches, to enable multiple measurements with different thresholds. Multiple sensor elements can have different thresholds, by having differing geometry or size. It has applications in current sensing, and programmable magnetic logic, when multiple input currents are sensed. Changing the threshold can change the logic operation between AND and OR.

摘要： An electronic compass has a 2D magnetometer for determining two of the three components of the earth-magnetic field vector. Values for the magnitude and inclination of the field at the location of the device are given. If at least one of the body axes of the device is held horizontally in operational use, an educated guess can be made about the actual orientation of the device (e.g., heading and tilt angles) with respect to the earth. Accordingly, this compass is a very-low cost device.

摘要： The dental position tracking system includes a toothbrush (30) which has a system (20) for determining the orientation of the toothbrush in the mouth of a user relative to the earth, based on measured stored information. Information is stored in the toothbrush concerning target ranges of expected measured toothbrush orientations for each of a plurality of dental zones (22). A processor (24) compares the measured toothbrush orientation information with the target orientation ranges, following conversion of both the target orientation information and the measured toothbrush orientation information to the same coordinate system. The processor then determines which if any of the target ranges matches, within a selected tolerance thereof, with the toothbrush orientation information. Any difference between the target range and the measured toothbrush orientation information is then used to partially adjust the target information range, in order to compensate for a change of position of the user's head.
