  • OUT-OF-BAND PAIRING FOR WIRELESS NEURAL IMPLANT
    Publication number: 20240232340
    Abstract: Systems and methods confirm a wireless pairing between an implanted device, such as a neural implant, and an external device, such as a computer or mobile device. The implanted device receives signals from the external device, which may be a varying magnetic field or a set of neural signals. The implanted device decodes the signals to identify a pairing code. Based on determining the pairing code, the implanted device may use this to perform a method of pairing which is not vulnerable to man-in-the-middle attacks. Alternatively, the implanted device can securely provide a pairing code to a helper device which can surface the pairing code to the user for confirmation.

  • 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.
