  • Publication number: 20240351864
    Abstract: An actuator layer of a MEMS sensor is be fabricated to include multi-level features, such as additional sense electrodes, vertical bump stops, or weighted proof masses. A sacrificial layer is deposited on the actuator layer such that locations are provided for the multi-level features to extend vertically from the actuator layer. After the multi-layer features are fabricated on the actuator layer the sacrificial layer is removed. Additional processing such as patterning of the actuator layer may be performed to provide desired functionality and electrical signals to portions of the actuator layer, including to the multi-level features.

  • Publication number: 20240302405
    Abstract: A dual axis accelerometer with a single proof mass measures in-plane acceleration (e.g., either along an x-axis or a y-axis), out-of-plane acceleration (e.g., normal to an x-y plane), and tilt of a fixed portion of a MEMS layer (e.g., normal to the x-y plane). In response to a tilt measurement, the dual-axis accelerometer compensates any offset (e.g., variability) of the out-of-plane accelerometer in order to maintain offset stability. In some embodiments, multiple dual axis accelerometers, perpendicularly configured, may be implemented via processing circuitry to offer three axis sensitivity capability.

  • Patent number: 11231441
    Abstract: Exemplary embodiment of a tilting z-axis, out-of-plane sensing MEMS accelerometers and associated structures and configurations are described. Disclosed embodiments facilitate improved offset stabilization. Non-limiting embodiments provide exemplary MEMS structures and apparatuses characterized by one or more of having a sensing MEMS structure that is symmetric about the axis orthogonal to the springs or flexible coupling axis, a spring or flexible coupling axis that is aligned to one of the symmetry axes of the electrodes pattern, a different number of reference electrodes and sense electrodes, a reference MEMS structure having at least two symmetry axes, one which is along the axis of the springs or flexible coupling, and/or a reference structure below the spring or flexible coupling axis.

  • Patent number: 10551191
    Abstract: An exemplary sensor may include a MEMS layer anchored to a cap and a substrate by anchoring portions of the MEMS layer. A suspended spring-mass system may include springs, at least one rigid mass, and at least one movable mass. The anchoring springs may be torsionally compliant about one or more axes and coupled to the rigid mass such that forces imparted by the anchoring portions are not transmitted to the movable mass.

  • Patent number: 6666730
    Abstract: The invention relates to an electric connector for use in vehicles. The connector comprises a first connector body having a first housing, a first opening, and a first projecting portion and a second connector body having a second housing, a second opening, and a second projecting portion. Pluralities of contacts have indented portions such that when the contacts are correctly inserted into the first and second housings, the indented portions correspond with the first and second openings. As a result, when the second connector body is received in the first connector body the first projecting portion is received in the second opening and the second projecting portion is received in the first opening to reciprocally couple the first and second connector bodies.
