Abstract: A needle implantable atrial fibrillation monitor includes a plurality of terminals that generate a terminal voltage when the needle implantable atrial fibrillation monitor is implanted in a patient's body. An analog processing circuit generates a monitoring signal based on the terminal voltage. An analog to digital converter converts the monitoring signal to monitoring data. A processor analyzes the monitoring data, generates events and compresses the event data and that generates compressed data in response thereto. A memory stores the compressed data. An RF interface transmits the compressed data to a base station via RF signaling when the needle implantable atrial fibrillation monitor is implanted in the patient's body.

Abstract: A Physical Layer Device is disclosed having power savings features operable during auto-negotiation for multiple technologies. Excessive power consumption is alleviated by decreasing the power required by the receiver(s) during parallel detection. The Physical Layer Device includes at least one port, with each port including a parallel detection receiver for receiving data and messages from a connected device, the data and messages including autonegotiation fast link pulses indicating a technology capability of the connected device, a cycler for enabling the parallel detection receiver for a fraction of an autonegotiation period and a controller for controlling the cycler. The enabling of the receiver for each port, whether a multiple or single port device, is staggered to prevent more than one receiver from being enabled at one time.
