  • Blunt Force Sensor Array
    Publication number: 20230147160
    Abstract: A blunt force sensor array for application to a non-planar surface includes a flexible thin-film substrate, a plurality of force sensors secured to the flexible thin-film substrate proximate to a center measurement point, a strain gauge secured on the flexible thin-film substrate proximate to the center measurement point, and a sensor interface configured to connect to external measurement and control circuitry. The sensor interface may be electrically connected to each of the force sensors and the strain gauge via traces disposed on the flexible thin-film substrate. The flexibility and shape of the flexible thin-film substrate may permit the blunt force sensor array to be applied to the non-planar surface to detect forces and strains experienced by the non-planar surface in response to a blunt force event on the non-planar surface.

  • Face detection, augmentation, spatial cueing and clutter reduction for the visually impaired
    Patent number: 10013599
    Abstract: An apparatus for improving performance of a retinal implant may include processing circuitry. The processing circuitry may be configured to receive image data corresponding to a camera field of view, determine whether a particular object is detected within the camera field of view, perform image data processing to enable a representation of a portion of the image data corresponding to an implant field of view to be provided on a retinal implant where the implant field of view is smaller than the camera field of view, and, responsive to the particular object being located outside the implant field of view, provide a directional indicator in the implant field of view to indicate a location of the particular object relative to the implant field of view.
