Abstract: A method for a MEMS device comprises determining in a computer system, a first driving signal for the MEMS device in response to a first time delay and to a base driving signal, applying the first driving signal to the MEMS device to induce the MEMS device to operate at a first frequency, determining a second driving signal for the MEMS device in response to a second time delay and to the base driving signal, applying the second driving signal to the MEMS device to induce the MEMS device to operate at a second frequency, determining a first quality factor associated with the MEMS device in response to the first frequency and the second frequency, determining a quality factor associated with the MEMS device in response to the first quality factor, and determining whether the quality factor associated with the MEMS device, exceeds a threshold quality factor.

Abstract: A method for a system includes applying power to a MEMS device while inhibiting applying power to a processor, thereafter determining first sensed data with the MEMS device in response to first event data, when the first sensed data exceeds a first threshold, determining second sensed data with a second MEMS device in response to second event data, when the second sensed data exceeds a second threshold, applying power to the processor, determining with the processor whether a seismic event is occurring in response to the first and the second sensed data, directing with the processor, an electronically-controllable mechanism to shut-off a utility supply, in response to the seismic event being determined.

Abstract: A method is provided for implementing a security mechanism in an integrated MEMS (Micro-Electro-Mechanical-System) device having a MEMS sensor with an output register associated with a sensing operation, the integrated MEMS device being electrically coupled to a computing system programmed to perform the method. The method includes, in normal operation, reading from the output register an output of the sensing operation, and in a test mode, determining, by a processor disposed within the computing system, a random value. Determining the random value can include reading from the output register, which in the test mode or provides a value from an internal pattern generator. The method also includes determining, by the processor, a validation value, reading, by the processor, the random value stored in the output register; and determining, by the processor, whether the integrated device is valid using the validation value and the random value stored in the output register.
