  • Patent number: 10186629
    Abstract: The present disclosure generally relates to thin film liftoff processes for use in making devices such as electronic and optoelectronic devices, e.g., photovoltaic devices.

  • Patent number: 9877553
    Abstract: A walking cane is provided having an elongated length, a handle grip, a forward-directed illumination source, and an ambient light sensor. The device provides a cane-user with forward illumination during twilight and dark periods, whereby the ambient light sensor operably energizes the light source when in an appropriate operational mode. A secondary mode allows the user to manually operate or deactivate the light source by hand controls, wherein each option is selectable from a three-way switch at the base of the handle grip. The length of the cane may be adjustable and its structure may take on an ergonomic shape, while the lower distal end is capped with a cane ferrule.

  • Patent number: 9761040
    Abstract: A new hardware architecture defines an indexing and encoding method for accelerating incoherent ray traversal. Accelerating multiple ray traversal may be accomplished by organizing the rays for minimal movement of data, hiding latency due to external memory access, and performing adaptive binning. Rays may be binned into coarse grain and fine grain spatial bins, independent of direction.
