Abstract: A sensor system includes first and second MEMS structures and a processing circuit. The first and second MEMS structures are configured to produce first and second output signals, respectively, in response to a physical stimulus. A method performed by the processing circuit entails receiving the first and second output signals and detecting a defective one of the first and second MEMS structures from the first and second output signals by determining that the first and second output signals are uncorrelated to one another. The method further entails utilizing only the first or the second output signal from a non-defective one of the MEMS structures to produce a processed output signal when one of the MEMS structures is determined to be defective and utilizing the first and second output signals from both of the MEMS structures to produce the processed output signal when neither of the MEMS structures is defective.

Abstract: A pet door is provided herein. The pet door includes a pivotal flap and a frame that defines a through-way. A rotatable knob is mounted to the frame and has a handle portion and a stop wall. The handle portion and stop wall include various profiles and configurations that work in concert to control the flap's direction of pivotal movement. In a first configuration, the flap may swing outwardly or inwardly. A second configuration prevents the flap from swinging inwardly. A third configuration prevents the flap from swinging outwardly. A fourth configuration places the flap is in a locked position to prevent swinging in either direction. The electronic door also includes an electronic latch mechanism which selectively latches and unlatches the flap. The latch mechanism unlatches the flap in response to a wireless signal from an electronic transmitter that may be affixed to a pet.

The housing divides the basin into a drinking basin and an interior basin. The housing includes an upright sidewall extending from a floor and a cap. The housing also defines an elevated water reservoir with a spout. A rotating cone is positioned within the housing and driven by a motor. The cone has a water inlet and a top opening adjacent the cone top opening. During operation, the rotation of the cone forces water to climb the interior surface of the cone through centrifugal force, where the water is deposited within the reservoir and returned to the drinking basin through the spout.
