  • Publication number: 20220201403
    Abstract: An audio system including an optical microphone and an audio controller. The optical microphone includes a light source and a detector. In some embodiments, the light source illuminates skin of a user. Alternatively the optical microphone also includes a membrane, and the light source illuminates a portion of the membrane. Sounds from a local area cause vibrations in the skin (or vibrations in the membrane). The detector may be in an interferometric configuration or a non-interferometric configuration with the light source. The audio controller monitors the vibrations of the skin (or membrane) using signal output from the detector, and measures the sounds using the monitored vibrations.

  • Patent number: 11139036
    Abstract: Provided are an apparatus, memory device, and method for using variable voltages to discharge electrons from a memory array during verify recovery operations. In response to verifying voltages in memory cells of the non-volatile memory array programmed during a programming pulse applying charges to the storage cells, a memory controller concurrently applies voltages on wordlines of the non-volatile memory array to clear the non-volatile memory array of electrons and applies voltages to the bitlines to perform bitline stabilization.

  • Publication number: 20210257036
    Abstract: Techniques and mechanisms for verifying the programming of a multi-bit cell of a memory array. In an embodiment, program verification is performed based on a signal, other than a word line voltage, which includes an indication of a reference voltage that is to be a basis for evaluating a currently programmed threshold voltage of a memory cell. A determination that the particular indication is to be communicated with the signal is made based on a detected state of the memory device which includes the memory cell. In another embodiment, the detected state includes one of a thermal condition at the memory array, a pressure condition at the memory array, a wear condition of the memory array, or a relative position of the cell with respect to one or more other cells of the memory array.

  • Patent number: 10765306
    Abstract: An improved endoscopic device for obtaining 3-dimensional human vision simulated imaging with real dynamic convergence in therapeutic, diagnostic, and other applications. Imaging probes are mounted on a tubular shaft and a simple/sleek slider moves back-and-forth on the shaft, with slider movement optionally modified and redirected to affect imaging probe convergence/divergence. Imaging probe convergence/divergence can be optionally manual for visual target selection, and the probe arms upon which the imaging probes are mounted may also be moved through a combined 180 degree movement range using a manual control. The first and second movement transmitting means respectively adapted to cause slider-initiated convergence, or manual convergence, of the imaging probes each share at least one integrated movement element with the control means adapted for engaging and disengaging the first and second movement transmitting means.

  • Publication number: 20190350622
    Abstract: A device for facilitating a total laparoscopic hysterectomy includes a cervical cup adapted to abut the cervicovaginal junction. An electrocautery wire has an uninsulated portion housed in the cervical cup which includes a channel for housing and controlled releasing the uninsulated portion. An introducer is coupled to the electrocautery wire and configured to penetrate the cervicovaginal junction thereby introducing the electrocautery wire into the intra-abdominal cavity. A shaft secures the electrocautery wire and pulling the electrocautery wire causes a controlled release of the uninsulated portion along a predetermined circumferential path around the cervix along the channel. Thus, the vagina is severed from the cervix along the circumference of the cervicovaginal junction.
