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.

Remote monitoring for networked fluid infusion systems

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. The system may have more than two different operating modes, which may be desirable if the number of wireless devices in the system exceeds two.

System and method for variable beacon timing with wireless devices

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 the main voltage 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 main battery 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.

Method and apparatus for predicting end of battery life

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. The networked medical devices are configured to support a variety of wireless data communication protocols for efficient communication of data within the medical device network. In addition, the wireless medical devices may be configured to support a number of dynamically adjustable wireless data communication modes to react to current operating conditions, application-specific data content, or other criteria.
