  • Patent number: 11957893
    Abstract: A neuromodulation therapy is delivered via at least one electrode implanted subcutaneously and superficially to a fascia layer superficial to a nerve of a patient. In one example, an implantable medical device is deployed along a superficial surface of a deep fascia tissue layer superficial to a nerve of a patient. Electrical stimulation energy is delivered to the nerve through the deep fascia tissue layer via implantable medical device electrodes.

  • Patent number: 11949725
    Abstract: One embodiment provides for a media playback device comprising a memory device to store instructions; one or more processors to execute the instructions stored on the memory device, the instructions to cause the one or more processors to provide a playback queue manager to manage one or more media playback queues including a set of media items associated with a scheduled event and a playback routing manager to determine an output destination for the set of media items based on context associated with the scheduled event, the playback routing manager to route output of playback of the set of media items to one or more of multiple different connected media playback devices based on the context associated with the scheduled event.

  • Patent number: 5691966
    Abstract: A method and apparatus for recording onto or playing back from a magneto optical disk eight channels of digital audio data. Eight channels of serial audio data, for example in a AES/EBU format is converted to parallel data and provided to one or more buffers via a DMA controller. After buffering, the data may be recorded onto a MO disk via an SCSI.

  • Patent number: 5315300
    Abstract: The invention relates to a C block generator for generating the C bits for a plurality of devices using the AES/EBU format. The C block generator preferably comprises an eight switch dip switch for selecting a desired one out of 256 possible C block sequences. The dip switch is connected to the upper eight bits of an EPROM's address input for indicating to the EPROM which sequence has been selected. The lower eight bits of the EPROM's address input are connected to an eight bit binary counter which is reset at the initiation of the transmission of each block. The EPROM uses the count from the counter to indicate which bit will be generated out of the selected sequence. Thus, as the count progresses, the generation of the sequence of C bits progresses in synchronism. The invention allows an operator to easily change the C block by simply opening or closing the appropriate switches on the dip switch.

  • Patent number: 4209250
    Abstract: A system for making multiple copies of a hologram or multiple original holograms on successive segments of a continuous length of blank film is disclosed herein. In the former case, this system includes two support arrangements, one for maintaining the original hologram in a fixed planar position and the other for maintaining the successive segments of blank film in a fixed copying position behind the original. In this particular system, the original hologram is held in place between two light transparent support plates, a front plate and a back plate, with the aid of a refractive index matching liquid and each successive segment of blank film is located across the back plate and maintained in a fixed position laterally therefrom solely by means of a continuous layer of preselected liquid substance which, at the same time, functions as an index matching medium. In the latter case or making original holograms, the original hologram just recited and its means for support would not be used.

  • Patent number: H1752
    Abstract: Disclosed is a recorder/editor apparatus for recording and editing digital audio data. A single digital signal processor (DSP) is used to control processing of digital audio data which corresponds to up to eight simultaneous audio channels. A plurality of buffers and a direct memory access controller (DMA) are provided such that the digital audio data may be recorded and played back from a magneto optical (MO) disk drive via a SCSI.
