  • Patent number: 10317532
    Abstract: A laser is used to emit a diverging laser flash configured to illuminate a detection zone. A pseudoimaging optical receiver system is used to detect reflections from objects in the detection zone. The receiver system includes a time-gated photodetector array that is used to record signatures in a voxel array. A voxel processing module receives the voxel array and detects a reference clutter signal within the array. Potential targets are then detected according to target signals in relation to the reference clutter signal.

  • Patent number: 10207410
    Abstract: A system and apparatus for navigating and tracking a robotic platform includes a non-contact velocity sensor module set positioned on the robotic platform for measuring a velocity of the robotic platform relative to a target surface. The non-contact velocity sensor module set may include a coherent light source that is emitted towards the target surface and reflected back to the coherent light source. Measuring the change in intensity of the reflected coherent light source may be used to determine the velocity of the robotic platform based on the its relationship with the principles of a Doppler frequency shift. A communication unit may also be utilized to transmit data collected from the non-contact velocity sensor set to a computer for data processing. A computer is then provided on the robotic platform to process data collected from the non-contact velocity sensor set.

  • Patent number: 10014552
    Abstract: Embodiments of the disclosed lithium ion rechargeable battery include an anode, a cathode, and a separator including an electrolyte to prevent physical contact between the anode and the cathode, while also providing medium for transporting the lithium ions. In some embodiments, the anode may include a microporous scaffold structure that includes a silicon crystal covered in a thin polycrystalline silicon cover. Additionally, the various embodiments described herein further describe increasing the surface area of the microporous scaffold structure so as to provide a more efficient charge flow between the anode and the cathode. In some embodiment, the two or more microporous scaffold structures are stacked on top of one another so that there is an increase in contact area and reduced contact resistance, thus further increasing the charge capacity of the disclosed lithium ion rechargeable battery.
