Abstract: An inertial sensor includes a substrate, a movable element having an edge, and a suspension system retaining the movable element in spaced apart relationship above a surface of the substrate. The suspension system includes an anchor attached to the surface of the substrate, the anchor having a first side laterally spaced apart from the edge of the movable element, and a spring structure having a first attach point coupled to the first side of the anchor and a second attach point coupled to the edge of the movable element. The spring structure includes beam sections serially adjoining one another, the beam sections extending from the first side of the anchor and surrounding the anchor to couple to the edge of the movable element. The spring structure makes no more than one coil around the anchor to position the first attach point in proximity to the second attach point.
Abstract: A sensor structure and a method for operating a vibrating sensor of angular velocity comprising a rotor mass and two linearly moving masses is disclosed. The sensor structure and method comprises a rotor mass, two linearly moving masses, and two T-shaped levers each coupled with the two linearly moving masses and to the rotor mass. The T-shaped levers enable the rotor mass and the two linearly moving masses to be excited into an anti-phase primary mode, where the direction of angular momentum of the rotor mass is opposite to the direction of angular momenta of the linearly moving masses. Angular momenta of the rotor mass and the linearly moving masses cancel each other to a high extent, so that the total sum of angular momentum of the structure is very small. Nominal frequency of the anti-phase primary mode is distinctively low as compared to nominal frequencies of other possible primary modes, such as a parallel phase primary mode.
Abstract: A shoe traction testing and measuring device, comprising a base frame, a rear leg assembly, a front leg assembly, a hip joint, and a piston. The piston is connected to the base frame and the rear leg assembly. A lower portion of the rear leg assembly is connected to the base frame and an upper portion of the rear leg assembly is connected to an upper portion of the front leg assembly at the hip joint. The front leg assembly comprises an articulating ankle and a replica foot, which is configured to don a shoe to be tested. When the piston actuates forward, the upper portion of the rear leg assembly tilts forward, which causes the front leg assembly to move forward and downward, simulating a step of a human, which causes the shoe on the replica foot to contact a force plate or a surface that is on top of the force plate.

Abstract: A method for closed loop operation of a capacitive accelerometer uses a single current source (62) and a single current sink (64) to apply an in-phase drive signal V1? to a first set of fixed capacitive electrode fingers and a corresponding anti-phase drive signal V2? to a second set of fixed capacitive electrode fingers. This provides a net electrostatic restoring force on the proof mass for balancing the inertial force of the applied acceleration and maintains the proof mass at a null position.

Abstract: According to one embodiment, a gyro sensor system including a gyro sensor unit is disclosed. The unit includes a movable body, a spring mechanism, a detector, an adjuster, and a rotation angle acquisition unit. The spring mechanism vibrates the movable body. A detector detects an amplitude of vibration of the movable body due to Coriolis force. The adjuster adjusts a first resonance frequency of vibration of the movable body in free vibration and a second resonance frequency of vibration of the movable body due to Coriolis force on the movable body so that the first and second resonance frequencies are to coincide with each other based on the amplitude of the vibration due to Coriolis force. The rotation angle acquisition unit acquires a rotation angle of the movable body, based on the amplitude of the vibration due to Coriolis force.
Abstract: A fixing device includes first and second rotatable members; a movable member; a first supporting side plate including an opening; a second supporting side plate; a detecting portion; a supporting plate; a holding portion; a slit portion; a first projected portion; a second projected portion; and a hole. When the position of the holding portion with respect to the height direction is regulated by the second projected portion in contact with the supporting plate, in a projection plane in which the outside of the first supporting side plate is viewed in the longitudinal direction of the first rotatable member, the flag portion is accommodated inside the opening and is in a non-overlapping position with the detecting portion. When the projected portion is engaged in the hole, in the projection plane, the flag portion is in an overlapping position with the detecting portion.
Abstract: A MEMS sensor device comprises a support substrate, a proof mass movably connected to the support substrate, a first drive comb fixedly connected to the support substrate in a first orientation and adjacent to the proof mass, and a second drive comb fixedly connected to the support substrate in a second orientation and adjacent to the proof mass. The second orientation is opposite of the first orientation such that the first and second drive combs face toward each other. A parallel plate sense electrode is located under the proof mass on the support substrate. The drive combs and the parallel plate sense electrode are each electrically charged and configured with respect to the proof mass such that a combination of a levitation force and a parallel plate force produces a linear out-of-plane actuation that depends only on an applied voltage.

Abstract: Novel structural features applicable to a variety of inertial sensors. A composite ring composed of concentric subrings is supported by a compliant support structure suspending the composite ring relative to a substrate. The compliant support structure may either be interior or exterior to the composite ring. The compliant support may be composed of multiple substantially concentric rings coupled to neighboring rings by transverse members regularly spaced at intervals that vary with radius relative to a central axis of symmetry. Subrings making up the composite ring may vary in width so as to provide larger displacement amplitudes at intermediate radii, for example. In other embodiments, electrodes are arranged to reduce sensitivity to vibration and temperature, and shock stops are provided to preclude shorting in response to shocks.
