  • Patent number: 8805526
    Abstract: A system including an external medical data telemetry device to communicate with an implantable medical device (IMD). The external medical data telemetry device includes a processor, a reconfigurable radio-frequency (RF) transceiver circuit, at least one far-field antenna, and a user interface. The reconfigurable RF transceiver circuit modulates an outgoing IMD data signal and demodulates an incoming IMD data signal using a modulation type that is selectable from a plurality of modulation types by the processor. The processor selects the modulation type using information entered by a user through the user interface.

  • Patent number: 8352040
    Abstract: A system for communicating with an implantable medical device via RF telemetry is disclosed which mitigates the effects of nulls caused by, e.g., multi-path distortion. In one embodiment, signals transmitted by the implantable device to an external device are simultaneously received with a pair of separate spaced apart first and second antennas. The antennas may provide spatial and/or polar diversity. The presence of nulls in the implantable device's transmission pattern can be determined by detecting an error rate in the signals received from the implantable device with each antenna.

  • Patent number: 7103413
    Abstract: An implantable medical device such as a cardiac pacemaker with a telemetry coil located in the device header rather than the conductive housing. The telemetry coil has a core made of magnetically permeable material such as ferrite in order to increase the efficiency of the coil and lessen space requirements.

  • Patent number: 5911422
    Abstract: A wheeled carrier suitable for carrying diverse articles on sandy terrain. The carrier has a body forming an upwardly open principal cargo receptacle, a closed second receptacle, upwardly oriented openings for carrying cups, horizontally disposed tubular openings for carrying rolled papers and the like, external pockets formed from flexible material, a collapsible carrying rack, and a collapsible towing handle. The principal receptacle has a seat belt for securing a child therein. The carrier has four wheels supported on brackets and axles suspended beneath the body. Each wheel has an associated skid pivotally supported on the axle supporting its associated wheel. Each skid is configured in the manner of a ski, for assisting the carrier in negotiating ridges and similar obstructions present in sandy terrain.
