  • Patent number: 10317200
    Abstract: The present disclosure relates generally to wearable devices and methods for detecting relative surface orientation. The wearable devices and methods may include a multi-mode sensor comprising emitter-detector combinations (e.g., sets or pairs) that have various spacings between the light emitter and the photodetector. Proximity curves can be generated based upon the various emitter-detector pair spacings, and used to assess surface distance and angular orientation of the wearable device to a body surface of an individual. In some variations, location and/or orientation of the device relative to the body surface is determined based on mapping data acquired by one or more emitter-detector pairs to surface distance (z distance) values based on proximity curve data stored in a memory of a device controller.

  • Patent number: 10305247
    Abstract: An optical apparatus includes an array of lasers, which are arranged in a grid pattern having a predefined spatial pitch and are configured to emit respective beams of pulses of optical radiation. Projection optics having a selected focal length project the beams toward a target with an angular pitch between the beams defined by the spatial pitch and the focal length. A scanner scans the projected beams over a range of scan angles that is less than twice the angular pitch. Control circuitry drives the lasers and the scanner so that the pulses cover the target with a resolution finer than the angular pitch. A receiver receives and measures a time of flight of the pulses reflected from the target.

  • Patent number: 10302765
    Abstract: An area monitoring system is configured to include a monitoring apparatus and a reflector. The monitoring apparatus includes a time-based detecting unit (i.e., a first detecting unit) that detects an intruder at a scanning angle by measuring a distance to an object based on an elapsed time until reflected light is received, for a first detection area. The monitoring apparatus further includes a light reception amount-based detecting unit (i.e., a second detecting unit) that detects an intruder at a scanning angle by comparing an actual light reception amount at a timing at which reflected light is received when radiated laser light is reflected by a reflector, and a light reception threshold (i.e., a reference light reception amount) set in advance, with a second detection area set farther than the first detection area as an area subjected to detection.
