A diversity antenna system including a plurality of antennas can include an antenna interface circuit configured to connect an antenna of the plurality of antennas to a transceiver using an antenna selection signal. The antenna control circuit can be configured to produce the antenna selection signal using at least one of a random sequence generator configured to generate a random antenna selection signal or a predetermined sequence generator configured to generate a predetermined antenna selection signal according to a predetermined sequence.
摘要:
A far-field radio frequency telemetry (RF) system for communicating with an implantable medical device includes a diversity antenna system. An antenna control circuit selects one or more antennas of the diversity antenna system for reducing potential data transmission errors associated with nulls encountered by the telemetry system due to environmental reflections of RF electromagnetic waves. In one embodiment, a different active antenna is selected when a transmission failure deemed to be associated with a null is detected. In another embodiment, a new antenna is selected on a regular basis to reduce the probability of encountering a null. In another embodiment, the telemetry system includes multiple processing paths each associated with one antenna of the diversity antenna system, and a different processing path is selected when the transmission failure deemed to be associated with a null is detected.
摘要:
A system and method for providing digital data communications over a wireless intra-body network is presented. A physical protocol layer is logically defined with an identifier uniquely assigned to a plurality of implantable devices in an intra-body network. Functions are specified within the physical protocol layer to transact data exchange over a wireless interface. A slave implantable device is activated in response to an activation signal transmitted through the wireless interface by a master implantable device. A wireless communications link is established between the slave implantable device and the master implantable device upon matching of the identifier assigned to the slave implantable device. Data is communicated intra-bodily over the communications link.
