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.
