Abstract: A method for controlling data flow in a wireless body area network includes transmitting sensor data from a plurality of sensor nodes to a gateway via a first transmission channel. The method further includes transmitting beacon data from the gateway to the plurality of sensor nodes via the first transmission channel. The method also includes determining channel packet loss information of the first transmission channel based on at least one of a beacon packet loss information included in the sensor data and a sensor packet loss information included in the beacon data. The method further includes comparing the channel packet loss information with a packet loss threshold. The method also includes switching flow of the sensor data and the beacon data through a second transmission channel instead of the first transmission channel, if the channel packet loss information is greater than the packet loss threshold.

The first channel is configured as a charging channel and is configured to at least one of wirelessly receive or transmit power. The first channel is also configured to transmit network pairing information for at least one of pairing or un-pairing the first network member and a second network member. The network pairing information is transmitted over the first channel at a first frequency. The second channel is configured as an operational channel, and is configured to communicate operational information between the first and second network members when the first and second network members are paired. The operational information is transmitted over the second channel at a second frequency that is different than the first frequency.

Abstract: One system includes a pattern generator that generates one or more excitation patterns suitable for probing a hydration level of a tissue of a subject at one or more depths from a surface of the subject into an interrogation region. Each of the excitation patterns has a spatial sensitivity at one of the one or more predetermined depths. A data analysis module receives one or more measured responses of the subject at a plurality of electrodes to excitation applied by the plurality of electrodes based on the one or more excitation patterns and determines one or more hydration changes at the one or more depths within the subject based on the measured responses. Each of the measured responses corresponds to the one of the one or more predetermined depths for which the applied excitation pattern has spatial sensitivity.

Abstract: Systems and methods for managing patient monitoring devices are disclosed. Patient information is transmitted from a patient sensor operatively coupled to a patient to a patient monitor. The patient sensor and the patient monitor are communicatively coupled over a communications network available in a designated monitoring area. Further, loss of the patient sensor from the designated monitoring area is detected by one or more of the patient sensor, the patient monitor and a user. One or more loss prevention indicators are initiated at the patient sensor upon detecting the loss of the patient sensor. Additionally, the loss prevention indicators are communicated to indicate location of the lost patient sensor.
