Abstract: An antenna system and method is provided for communicating with a medical device implanted in a patient. Upper and lower shells join to form an antenna tunnel there between. At least one of the upper or lower shells includes an opening along an edge thereof to form a passage to the antenna tunnel. The upper shell includes an outer patient engaging surface configured to abut against the patient. An antenna assembly includes a substrate and an inductive RF antenna provided on the substrate. The antenna assembly is movable within the antenna tunnel. The substrate includes a stem projecting through the passage. A handle is joined to the stem and is located outside of the antenna tunnel. The antenna assembly is movable within the antenna tunnel in response to adjustment of the handle relative to the upper and lower shells. An electronics circuit is electrically coupled to the antenna and is configured to transmit and receive inductive RF signals to and from the medical device implanted in a patient.

Abstract: A disk drive is disclosed comprising a disk, a head actuated over the disk, a host interface for receiving disk access commands from a host, a command queue for queuing the disk access commands, and a stream detection engine for evaluating the disk access commands to detect a plurality of streams accessed by the host. The stream detection engine maintains a stream data structure for each detected stream, wherein the stream data structure comprises a frequency counter for tracking a number of disk access commands associated with the stream out of a predetermined number of consecutive disk access commands received from the host. A disk controller selects one of the streams for servicing in response to the frequency counters.
