    摘要： An inertial sensor module includes: a first inertial sensor having a first axis as a detection axis; and a second inertial sensor having the first axis as a detection axis, in which detection accuracy of the first inertial sensor is higher than detection accuracy of the second inertial sensor, and the operation circuit receives a detection signal of the first axis output from the first inertial sensor and a detection signal of the first axis output from the second inertial sensor, and selects and outputs either a first output signal based on the detection signal of the first axis output from the first inertial sensor or a second output signal based on the detection signal of the first axis output from the second inertial sensor.

    摘要： A sensor assembly for a head-mountable device, the sensor assembly comprising: a flex circuit, an inertial measurement unit coupled to the flex circuit, an enclosure disposed around the inertial measurement unit and a portion of the flex circuit, to define a sealed volume containing the inertial measurement unit and the portion of the flex circuit. Thereby, a head-mountable device can securely support sensors in a manner that maintains their positions and orientations over time and isolates the sensors from an external environment. The sensor can be mounted within a sealed enclosure while maintaining an operable connection to the sensor. The sensor assemblies provides high robustness during the entirety of the service life of the head-mountable device without placing strain on the sensors themselves. The seal of the enclosure can isolate the sensor from external influences by preventing ingress of elements through the case and plate.

    摘要： An example transducer includes an upper magnetic circuit assembly including an upper excitation ring, a lower magnetic circuit assembly including a lower excitation ring, and a proof mass assembly positioned between the upper and lower magnetic circuit assemblies. A coefficient of thermal expansion (CTE) of the proof mass assembly is lower than a CTE of each of the upper and lower excitation rings. The transduces also includes an outer support structure coupled to an outer surface of each of the upper and lower excitation rings, and the outer support structure includes at least one cutout configured to reduce a circumferential stiffness of the outer support structure.

    摘要： A portable electronic device includes a status detector and a processor. The status detector is configured to obtain acceleration data from a motion sensor of the portable electronic device. The status detector is further configured to determine, for each acceleration measurement in the acceleration data, whether the acceleration measurement satisfies an acceleration threshold. Responsive to the acceleration measurement satisfying the acceleration threshold, the status detector is configured to increment a first counter. Responsive to the acceleration measurement not satisfying the acceleration threshold, the status detector is configured to selectively increment or refrain from incrementing a second counter. The status detector is further configured to determine whether the portable electronic device is in an on-table or an off-table state based on whichever of the counters reaches a counter threshold. The processor is configured to configure one or more components of the portable electronic device based on the determined state.

    摘要： A Micro-Electrical-Mechanical-Systems (MEMS) accelerometer system includes a proof-mass device having a proof-mass that moves from an initial position in response to an input acceleration, a transducer connected to the proof-mass device to output a transducer signal correlating to movement and/or position of the proof-mass, and a driver configured to drive the proof-mass. A controller actively controls the driver to actively drive the proof-mass toward an initial position, and actively adjusts the drive signal based on a temperature signal (T) indicative of given temperature, a transducer voltage signal (Vref) indicative of a transducer voltage reference, and the transducer signal to actively generate a corrected drive signal and delivers the corrected drive signal to the driver to actively control the driver. The controller can also utilize a robust loop-shaping stabilization operation to produce both an unfiltered estimate of the input acceleration and an uncorrected drive signal to stabilize the proof mass.

    摘要： A single body multi-mode mechanical resonator includes two or more spring-mass devices, one or more anchor springs, a phase 1 parallel plate electrode and a phase 2 parallel plate electrode, a plurality of interdigitated shaped combs, a plurality of interdigitated drive combs, and a plurality of interdigitated sense combs. The spring-mass devices further include two or more lumped masses and one or more anchor springs. The coupling springs couple the motion of the two or more lumped masses. The parallel plate electrodes apply forces to the in-phase mode that yield equal in magnitude but opposite in sign frequency shifts of the anti-phase mode. The shaped combs compensate for a frequency drift of the anti-phase mode and cancels first-order displacement effects. The drive combs are aligned to the anti-phase mode, with a frequency selective excitation. The sense combs are aligned to the anti-phase mode and capable of cancelling common-mode noise effects.
