  • Publication number: 20190366089
    Abstract: In electrically stimulating neural tissue it is important to prevent over stimulation and unbalanced stimulation, which would cause damage to the neural tissue, the electrode, or both. It is critical that neural tissue is not subjected to any direct current or alternating current above a safe threshold. Further, it is important to identify defective electrodes, as continued use may result in neural damage and further electrode damage. The present invention presents system and stimulator control mechanisms to prevent damage to neural tissue.

  • Publication number: 20180263655
    Abstract: A guidance device for ultrasonographic guidance of percutaneous placement of an intravascular introducer in a subject adapted for placement against the body of the subject essentially at a desired percutaneous insertion site is disclosed. A directing member is oriented such that the trocar or introducer received in the directing member provides for insertion of the trocar or introducer along a first axis. The guidance device is adapted to receive and releasably hold an ultrasonographic imaging probe such that a first axis of the directing member is positioned in a plane that is essentially perpendicular to and transversely crossing the imaging plane, and the directing member is coupled to the guidance device via an attachment member such that the directing member is configured to be movable only in the plane that is essentially perpendicular to the imaging plane.

  • Patent number: 9641026
    Abstract: The subject specification comprises enhanced communication infrastructure for a multi-tier hierarchical smart distribution grid (SDG). The SDG comprises a specified number of distribution network node controller (DNNC) components employed to desirably control communications and power distribution between respective tiers of the SDG to facilitate efficient power distribution. When communication between the a DNNC in one tier and another DNNC in another tier, is desired, the DNNC can identify available communication channels and respective communication conditions of the available communication channels, and can dynamically select a subset of available data and preferred communication channel, based at least in part on predefined control criteria, to control data transmission loads in the network and facilitate real time control of the SDG. Data can be communicated via the selected communication channel.

  • Patent number: 8953612
    Abstract: Embodiments of systems and methods for efficient broadcasting via random linear packet combining are described. A plurality of data packets are received from a data source according to embodiments. The plurality of data packets is divided into a plurality of data blocks, and bits associated with the plurality of data blocks are multiplied by a set of coefficients to generate a plurality of product values. An encoded data packet having a plurality of encoded data blocks may also be generated by linearly combining the plurality of product values for respective data blocks of each of the plurality of data packets into corresponding encoded data blocks of the encoded data packet. Because each encoded data packet includes information about a complete set of data packets, rather than just a subset, less broadcast redundancy may be required.
