Abstract: A fluid infusion system as described herein includes a number of local “body network” devices, such as an infusion pump, a handheld monitor or controller, a physiological sensor, and a bedside or hospital monitor. The body network devices can be configured to support communication of status data, physiological information, alerts, control signals, and other information between one another. In addition, the body network devices can be configured to support networked communication of status data, physiological information, alerts, control signals, and other information between the body network devices and “external” devices, systems, or communication networks. Such external communication allows the infusion system to be extended beyond the traditional short-range user environment.

Abstract: Systems and methods for supporting variable beacon timing for a first wireless device and a second wireless device are provided. An exemplary system may include a number of wireless devices configured to wirelessly communicate with one another. The system includes a beacon-transmitting wireless device and a listening wireless device. The beacon-transmitting wireless device is configured to transmit, during a first operating mode, wireless beacons separated in time by relatively long time intervals. The beacon-transmitting device is also configured to transmit, during a second operating mode, wireless beacons separated in time by relatively short time intervals. The listening wireless device is configured to listen, during the first operating mode, for wireless beacons transmitted by the beacon-transmitting wireless device, and is configured to listen, during the second operating mode, for wireless beacons transmitted by the beacon-transmitting wireless device.

Abstract: A powering subassembly for a portable electronic device includes a main battery, a converter, a backup battery, and a controller. The main battery provides a main voltage and the backup battery can provide a backup voltage. The converter receives the main voltage and increases it to at least one operating voltage. The controller receives the operating voltage from the converter, monitors the voltage of the main battery, and compares the monitored voltage to a main battery low voltage threshold. The controller transmits a disconnect signal to decouple the main battery from the converter if the monitored voltage from the main battery is less than the main battery low voltage threshold. The controller transmits a connection signal to couple the backup battery to the converter if the monitored voltage is less than the main battery low voltage threshold. The backup battery provides the power for a predetermined minimum amount of time.

Abstract: Operating techniques and methodologies for a body area network of medical devices are provided. One technique relates to an intelligent channel hopping scheme that detects loss of wireless synchronization on an initial wireless channel, thereafter obtains a measure of quality for the initial wireless channel, and then selects a new wireless channel when the obtained measure of quality fails to satisfy a threshold criteria. Another operating technique dynamically adapts an ordered list of available wireless channels in accordance with a quality measure of the available wireless channels. Thus, when quality degradation associated with a first wireless channel is detected, the ordered list can be updated to indicate a lower preference for the first wireless channel and to indicate a higher preference for a second wireless channel that does not suffer from quality degradation.
