摘要： An accelerometer as disclosed herein includes a support wafer, a bottom wafer, a top wafer, and an inductive pick-off. The support wafer may define a plane and may comprise a first side, a second side, and a proof mass. The proof mass may be configured to move in the plane defined by the support wafer. The bottom wafer may comprise a first side and a second side, and the first side may be positioned over the first side of the support wafer. The top wafer may comprise a first side and a second side, and the first side may be positioned over the second side of the support wafer. The inductive pick-off may comprise a near field resonant conductive coupling mechanism and may be configured to output a signal indicative of an amount of displacement of the proof mass to electronics.

摘要： An embodiment includes generating a sense signal that represents a first vibration of a platform, and reducing a level of the first vibration by generating, in response to the sense signal, a second vibration in the platform. For example, a sensor generates a sense signal representing a first vibration induced (e.g., a shock-induced vibration) in the platform. And a vibration-cancel circuit reduces or eliminates a level of the first vibration in response to the sense signal. For example, the vibration-cancel circuit reduces a magnitude of a first vibration induced in a platform, or eliminates the first vibration altogether, by generating, in the platform, a second vibration having a magnitude approximately equal to the magnitude of the first vibration and having a phase approximately opposite to the phase of the first vibration. That is, the second vibration cancels the first vibration to reduce the net vibration that the platform experiences.

摘要： An embodiment of an assembly includes a platform (e.g., a printed circuit board (PCB)), a sensor, and a vibration-cancel circuit. The sensor is mounted to the platform and is configured to generate a sense signal that represents a vibration induced (e.g., a shock-induced vibration) in the platform. And the vibration-cancel circuit is configured to reduce or eliminate a level of the vibration in response to the sense signal. For example, such a vibration-cancel circuit is configured to reduce a magnitude of a vibration induced in platform, or to eliminate the vibration altogether, by generating, in the platform, a counter vibration that has a magnitude approximately equal to the magnitude of the induced vibration and that has a phase approximately opposite to the phase of the induced vibration. That is, the counter vibration cancels the induced vibration to reduce the net vibration that the platform experiences.
