  • Patent number: 10338092
    Abstract: In a physical quantity sensor, a contact part that is directly and electrically connected to an external circuit is formed in a support substrate, and the support substrate is maintained at a predetermined potential through the contact part. With this configuration, the support substrate is maintained at the predetermined potential without disposing an electrode in the interior of the semiconductor layer. For that reason, a processing precision can be restrained from being reduced in forming the movable electrode, and hence a detection precision can be restrained from being reduced.

  • Patent number: 10331218
    Abstract: A gyroscopic motion feedback device utilizes one or more pairs of masses mounted on a common axis but independently rotatable to allow rapid variation of the gyroscopic force produced thereby. A sensor detects motion of the mount and a controller uses the detected motion to vary the relative rotational speed of the masses. The device provides haptic feedback where the mount is used to the control the interaction of an objection in a virtual environment, with the controller further varying the relatively rotational speed based on virtual interactions experienced by the object.
