    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： 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 MEMS device includes a substrate, a set of spring, and a proof mass suspended above and coupled to the substrate by the springs. Each spring includes a corresponding anchor on the substrate and a beam extending away from that anchor. Each beam has a fixed end that is coupled to the anchor by a first linkage at one end of the beam proximal to the anchor and a free end that is coupled to the proof mass by a second linkage at an end of the beam that is distal to the anchor. The anchors are arranged symmetrically around a center of the proof mass. The proof mass translates vertically with respect to the substrate and when a vertical displacement of the proof mass toward the substrate reaches a predefined value, the free end of each spring contacts the substrate and prevents the proof mass from contacting the substrate.
