摘要： A respiratory monitor comprises: a first sensor (20, 70) configured to generate a respiration-related motion monitoring signal (72) indicative of respiration related motion; a second sensor (20, 22, 80, 82) configured to generate a sound monitoring signal (84) indicative of respiration-related sound; and a signals synthesizer (90) configured to synthesize a respiratory monitor signal (46) based on the respiration-related motion monitoring signal and the respiration-related sound monitoring signal. A sensor for use in respiratory monitoring comprises an accelerometer (30) and a magnetometer (32) together defining a unitary sensor (20) configured for attachment to a respiring subject (10) so as to move as a unit responsive to respiration related motion of the respiring subject.

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 magnetic field sensor circuit comprises a first magneto-resistive sensor (Rx) which senses a first magnetic field component in a first direction to supply a first sense signal (Vx). A first flipping coil (FC1) applies a first flipping magnetic field with a periodically changing polarity to the first magneto-resistive sensor (Rx) to cause the first sense signal (Vx) to have alternating different levels synchronized with the first flipping magnetic field. A second magneto -resistive sensor (Ry) senses a second magnetic field component in a second direction different than the first direction to supply a second sense signal (Vy). A second flipping coil (FC2) applies a second flipping magnetic field with a periodically changing polarity to the second magneto -resistive sensor (Ry) to cause the second sense signal (Vy) to have an alternating different levels synchronized with the second flipping magnetic field. The first flipping magnetic field and the second flipping magnetic field have a phase shift. A differential amplifier (AMP1) receives the first sense signal (Vx) and the second sense signal (Vy) to obtain a difference signal (Vd). A first synchronous demodulator (DEM1) receives the difference signal (Vd) and a first switching signal (Q1) being phase locked to the alternating different levels of the first sense signal (Vx) to supply a first output signal (Vox) indicating the first magnetic field component. A second synchronous demodulator (DEM2) receives the difference signal (Vd) and a second switching signal (Q2) being phase locked to the alternating different levels of the second sense signal (Vy) to supply a second output signal (Voy) indicating the second magnetic field component.

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.

摘要： A high-performance, integrated AMR sensor has compensation and flipping coils for signal conditioning of the sensor output.

As a result, the dimensions of the die area of the AMR sensor and the package size can be kept small.
