A hinge for a microelectromechanical system includes a fixed part and a part movable relative to the fixed part along at least an out-of-plane direction, the hinge being intended to suspend the moving part from the fixed part. The hinge includes a first rigid part, a second part fixed to the first part at one end and intended to be anchored to the fixed part or the moving part. The second part deforms in bending in a first direction, two third parts are fixed to the first part and are anchored to the moving part or the fixed part, and the third parts deform in bending along a second direction orthogonal to the first direction.

A microelectromechanical device includes: a body; a movable mass, elastically coupled to the body and oscillatable with respect to the body according to a degree of freedom; a frequency detector, configured to detect a current oscillation frequency of the movable mass; and a forcing stage, capacitively coupled to the movable mass and configured to provide energy to the movable mass through forcing signals having a forcing frequency equal to the current oscillation frequency detected by the frequency detector, at least in a first transient operating condition.

A detection device includes: a drive circuit which receives a feedback signal from a physical quantity transducer and drives the physical quantity transducer; a detection circuit which receives a detection signal from the physical quantity transducer and detects a desired signal; and a control unit which controls switching on/off of an AGC loop in the drive circuit. The drive circuit outputs a drive signal based on a control voltage that is set by the AGC loop in an on-period of the AGC loop to the physical quantity transducer and thus drives the physical quantity transducer in an off-period of the AGC loop.

An electronic device includes an accommodation space formed between a first base material and a second base material so as to seal a space therebetween, and a functional element in the accommodation space. The accommodation space is formed in an inner region of a bonding portion between the first base material and the second base material. The electronic device includes wirings extending from the inner region through the bonding portion to the outside of the accommodation space. The bonding portion includes a first bonding region and a second bonding region. The wiring includes a first wiring portion having a first direction toward the outside through the first bonding region from the inner region and a second wiring portion having a second direction toward the outside through the second bonding region from the inner region. The first and the second directions are different.

MEMS gyroscopes are often integrated in modern electronic products for measuring orientation or rotation in those products. However, these MEMS gyroscopes are often inaccurate. The invention provides a compensation circuit to compensate for errors causing a distortion of a measured Coriolis force. The compensation circuit demodulates an input signal provided by the MEMS gyroscope to produce a quadrature signal indicative of the quadrature error and provides a compensation signal to the MEMS gyroscope for actively compensating the quadrature error.

The present disclosure relates to a measuring device and an execution method thereof characterized in that open/close status of a cover body over a can body is recognized, the cover body is unscrewed or extracted from the can body, status of the cover body separated from the can body is detected by an electronic module mounted on the cover body, and the electronic module transmits a message to an appliance with the cover body totally separated from the can body.

An oscillator has a first axis and a second axis as two axes perpendicular to each other and a third axis perpendicular to a plane containing the first axis and the second axis and includes a mass part including a support and a first displacement portion and a second displacement portion that are connected rotatably around the first axis to the support via beams and extend along the direction of the second axis. The first displacement portion is provided on one side of the mass part and the second displacement portion is provided on the other side of the mass part, and free ends of the first displacement portion and the second displacement portion face each other and are connected to each other via a connection portion.

A micro-electro-mechanical system includes a proof mass, an anchor, an amplifier, a sense element, a reference element, and a feedback element. The proof mass is configured to move in response to a stimulus. The anchor is coupled to the proof mass via a spring. The amplifier is configured to receive a proof mass signal from the proof mass via the spring and the anchor. The amplifier may be configured to amplify the received proof mass signal to generate an output signal. The sense element may be connected between the proof mass and a first input signal. The reference element may be connected between the anchor and a second input signal. The feedback element may be connected between the proof mass and the output signal. The feedback element and the sense element may change in response to proof mass displacement.
