  • Patent number: 11931307
    Abstract: A method of operating an exoskeleton system that includes obtaining a first set of sensor data from one or more sensors associated with one or more leg actuator units of an exoskeleton system during a user activity, the first set of sensor data indicating a first configuration state of the one or more actuator units; determining, based at least in part on the first set of obtained sensor data, to change configuration of the one or more leg actuator units to a second configuration state to support a user during the user activity; and introducing fluid to one or more fluidic actuators of the one or more leg actuator units to generate the second configuration state by causing the one or more fluidic actuators to apply force at the one or more actuator units.

  • Patent number: 8891405
    Abstract: A clustered network may include a plurality of switch boxes where a master switch box may communicate and control hardware devices in remote switch boxes. The switch boxes in the network may each include a multiplexer, for example, a field programmable array (FPGA) that may process message requests related to hardware devices of a switch box. If the hardware device is in a remote switch box, then the FPGA of the master switch box may process the status data from the remote switch box so that a local processor in the master switch box can read the status data.

  • Patent number: 7776600
    Abstract: Provided is a method for production of nanocrystalline hydroxyapatite particles, and nanocrystalline hydroxyapatite particles produced according to the method. The nanocrystalline hydroxyapatite particles exhibit substantially superior cell transformation abilities as compared to known and commercially-available calcium phosphate kits. The nanocrystalline hydroxyapatite particles also find use in tissue engineering applications, for example bone and tooth engineering and repair applications.

  • Publication number: 20070087959
    Abstract: A method of inducing biomineralization in a tissue, which method comprises administering to the tissue a source of Phosphophoryn (PP) in an amount sufficient to induce biomineralization; a method of treating tooth sensitivity or injured pulp tissue; a method of inducing differentiation of a cell into an osteogenic cell or odontogenic cell; a method of inducing bone or dentin regeneration; a method of inducing periodontal regeneration; a method of inducing differentiation of a cell into a cementoblast, osteoblast, or periodontal ligament cell; and a composition comprising a source of PP and a carrier.

  • Patent number: 7068679
    Abstract: The present invention involves the passing of clock information from a point where a tributary payload is mapped into a carrier to a point where a tributary payload is de-mapped from the carrier. A synchronization signal is generated at the mapping end. Rather than sending clock phase information implicitly by means of the data, as is normally the case, a value of the synchronization signal at a given time, is sent explicitly, independent from the payload data.
