摘要: A diagnosis system is configured to diagnose an apparatus including a driver device. The system includes an acquisition unit configured to acquire waveform data indicating a waveform related to a current to be supplied to the driver device, and a determination unit configured to determine a condition of the apparatus. The determination unit is configured to obtain, based on the waveform data, a change caused by a component of a force in a particular direction applied to the driver device, and to determine the condition of the apparatus based on the obtained change. The diagnosis device determines the condition of the apparatus accurately.

摘要: Proposed is a home appliance which allows a reception space defined therein to be seen from the outside through a viewing window without opening a door. In the home appliance, the viewing window is mounted to a door, and when a user knocks on the door, a vibration detection signal corresponding to vibration generated by the user’s knock is processed so as to accurately determine whether there is the vibration by the knock. Moreover, when the vibration generated by the knock is detected, the inside of the reception space is illuminated such that the inside of the reception space can be seen from the outside through the viewing window. Therefore, the user can see the inside of the reception space by a simple movement even without opening the door.

摘要: In certain embodiments, an accelerometer is a microelectromechanical systems (MEMS) device including a proof mass, an anchor located in an opening defined by a body of the proof mass, a spring, a drive electrode, and a sense beam. The spring and the proof mass form a spring system suspended from the anchor. The sense beam oscillates at a particular resonance frequency based on application of a signal to the drive electrode. The MEMS device further includes a support structure coupled to the anchor. The support structure operates as a stress decoupling area and includes a support beam, with the spring corresponding to an end of the support beam that has a reduced thickness. The sense beam has a first end attached to the proof mass and a second end attached to the support beam such that the sense beam is orthogonal to the support beam.

摘要: Described herein are accelerometers, apparatus and systems incorporating accelerometers, and techniques for controlling sensing operations in an accelerometer. In certain embodiments, an accelerometer is a microelectromechanical systems (MEMS) device including a proof mass, an anchor, a spring between the proof mass and the anchor, a drive electrode, and a sense beam. The anchor is located in an opening defined by a body of the proof mass. The spring and the proof mass form a spring system suspended from the anchor. The sense beam is configured to oscillate at a particular resonance frequency that changes according to a force generated by movement of the proof mass in response to acceleration. In some embodiments, a support structure couples the anchor to the spring and operates as a stress decoupling area that prevents or limits propagation of stress from the anchor to the sense beam and the spring system.

摘要: This disclosure is related to devices, systems, and techniques for determining an acceleration of a vibrating beam accelerometer (VBA). For example, a system includes processing circuitry configured to receive, from a first resonator, one or more electrical signals indicative of a frequency of a first mechanical beam and a frequency of a second mechanical beam, determine, based on the one or more electrical signals, the frequency of the first mechanical beam and the frequency of the second mechanical beam, and calculate, based on the frequency of the first mechanical beam and the frequency of the second mechanical beam, an acceleration of a proof mass assembly.
