Abstract: An exemplary non-invasive wearable brain interface system includes a headgear configured to be worn on a head of a user, a plurality of self-contained photodetector units configured to removably attach to the headgear, the photodetector units each comprising a plurality of photodetectors configured to detect photons of light after the photons reflect from a target within a brain of the use, and a master control unit coupled to each of the photodetector units and configured to control the photodetector units.

Abstract: An apparatus has a first emitter emitting at a first frequency optical pulses that form a first pulse collection. A second emitter emits at a second frequency optical pulses that form a second pulse collection. A first receiver collects during a time of flight time window a first reflected pulse collection corresponding to the first pulse collection reflected from a sensed object. A second receiver collects during the time of flight time window a second reflected pulse collection corresponding to the second pulse collection reflected from the sensed object. A processor analyzes the first reflected pulse collection and the second reflected pulse collection to produce first reflected pulse collection metrics and second reflected pulse collection metrics.

Abstract: An exemplary stacked photodetector assembly includes a first wafer and a second wafer bonded to the first wafer. The first wafer includes a SPAD and has a thickness T1 configured to minimize absorption by the first wafer of photons included in light incident upon the first wafer while the SPAD is in a disarmed state. The second wafer has a thickness T2 configured to provide structural support for the first wafer. The stacked photodetector assembly includes a fast gating circuit electrically coupled to the SPAD and configured to arm and disarm the SPAD.

Abstract: A wearable system includes a stacked photodetector assembly including a first wafer including a single photon avalanche diode (SPAD), the first wafer having a thickness T1 configured to minimize absorption by the first wafer of photons included in light incident upon the first wafer while the SPAD is in a disarmed state, and a second wafer having a thickness T2 including a fast gating circuit electrically coupled to the SPAD and configured to arm and disarm the SPAD, the second wafer bonded to the first wafer in a stacked configuration. The fast gating circuit includes a capacitor configured to be charged, while the SPAD is in the disarmed state, with a bias voltage by a voltage source, and supply, while the SPAD is in an armed state, the bias voltage to the SPAD such that a voltage across the SPAD is greater than a breakdown voltage of the SPAD.

Abstract: The present invention discloses an industrial high speed micro drill that is made to access remote and inaccessible locations in order to blend, grind, polish and cut materials and parts as determined by visual inspection powered via a pneumatic power source. The high speed drill is deployed by a controlled, articulating guide tube that acts in a multidirectional fashion to direct the action of the assemblage and allow for discrete manipulation of the pneumatically powered drill while harboring a channel and pneumatic power source carrying rubber tubing.
