  • THIN-FOIL SELF-RESONANT WIRELESS POWER COIL
    Publication number: 20230137530
    Abstract: A coil formed from a flexible polymer substrate that is printed with metal traces is disclosed in which the flexible substrate has notches that align each loop as the substrate is wound into a ring. The notches are precisely spaced so that the diameter of each loop is well controlled. As the substrate is wound, adhesive is applied along its length to fill gaps between each loop's layer. Ideally, the adhesive has a similar dielectric constant as the polymer substrate. The resulting coil has loops of metal traces separated by precise a thickness of dielectric. The precision in spacing between metal layers and dielectric allows the coil to be designed for self-resonance.

  • Neural Signal Compression for Brain-Machine Interface
    Publication number: 20230284982
    Abstract: Techniques for compressing neural signals are disclosed herein. The neural signal compression techniques can include lossless compression, lossy compression, binned spike compression, and spike-band power compression. Lossless compression can compress neural signals using a difference predictor to encode compressed neural signals via binary and unary coding. Lossy compression can compress neural signals using quantized wavelet transforms to generate an encoded bit-stream of compressed neural signals. Binned spike and spike-band power compression can leverage the sparse nature of neural signals to threshold the neural signals for generating an appended bit-stream of compressed neural signals.

  • BRAIN IMPLANT WITH SUBCUTANEOUS WIRELESS RELAY AND EXTERNAL WEARABLE COMMUNICATION AND POWER DEVICE
    Publication number: 20210007602
    Abstract: A brain-machine interface (BMI) is described in which many flexible electrodes for implanting within a subject's brain run to a cylindrical sensor device configured to fit inside a burr hole in the cranium. The devices contain sealed electronics that convert analog neural voltages to digital signals, or vice versa, and connects through a serial cable to a subcutaneous relay on the mastoid region (behind the subject's ear) or other suitable location. The relay draws power from and communicates with an externally worn device and distributes the power to the devices. The externally worn device communicates wirelessly or through a tether to a base station computer for data analysis and/or stimulation.

  • GLASS WELDING THROUGH NON-FLAT SURFACE
    Publication number: 20230069855
    Abstract: Methods and systems of using a laser beam to weld an object with a non-flat surface, including curved surfaces, are described, where at least one piece of the object is transparent. An optical guide with a flat surface and an interface surface is placed on a piece of an object to welded. The interface surface is fabricated to form-fit the non-flat surface of the object to be welded, and is opposite the flat surface. A liquid optical medium is applied between the non-flat surface and the interface surface, filling any gaps or surface defects. The laser beam is then transmitted through the optical guide, liquid optical medium, and into the object to be welded, to a location to be welded. The laser beam then welds the object to be welded at pre-determined points.
