  • Patent number: 9360547
    Abstract: An ultra wideband (UWB) or short-pulse RF system is disclosed that can be used to precisely locate or track objects (such as personnel, equipment, assets, etc.) in real-time in an arbitrarily large, physically connected or disconnected, multipath and/or noisy environment. A system implementation includes multiple zones or groups of receivers that receives RF signals transmitted by one or more timing reference tags and one or more objects having associated object tags. Each zone or group may share a common receiver. By combining a multiple reference tag system with a virtual group of receivers, i.e., a zoning technique or system, a cost-effective system can be provided that offers scalability and flexibility to monitor a significantly expanded coverage area.

  • Patent number: 9308305
    Abstract: An implantable blood pump includes motor control circuitry and power electronics circuitry integrated within the implantable pump body. The motor control circuitry and power electronics circuitry is configured to energize and control motor windings to rotate the pump rotor and impeller. Additional control circuitry and power electronics circuitry may be integrated within the pump housing to energize and control magnetic bearings of a magnetic levitation pump. A percutaneous cable coupled between the implantable blood pump and an extracorporeal monitor includes a reduced number of leads to provide power and control signals to the implantable blood pump. Wireless communication between the extracorporeal monitor and the integrated power electronics and control circuitry facilitates the use of a percutaneous cable with as few as two leads for providing power to the implantable pump.
