Abstract: A wireless sensing device and a method for operating a wireless sensing device are described herein. The wireless sensing device includes a battery power supply and a processor that transmits detected physiological parameters from the sensing device to a monitoring device. when the battery level within the sensing device falls below a minimum threshold, the processor of the sensing device reserves a portion of the battery charge to power an indicator to increase the noticeability of the sensing device. The sensing device can also include an RFID tag that is written to by the processor when the state of charge on the battery falls below the minimum threshold. The RFID tag allows RFID detectors to sense the presence of the sensing device without requiring additional battery power.

Abstract: Devices and methods for detecting a medical sensor device being attached to a host device are disclosed. The host device includes a reader circuit that can generate an AC pilot signal. When the medical sensor device is being attached to the host device, the AC pilot signal is fed to a non-linear circuit in the sensor device, which responds with a DC signal. The host device compares the magnitude of the response signal with a threshold magnitude. If the magnitude of the response signal is greater than the threshold magnitude, the host device determines that the sensor device is being attached and establishes connection with the sensor device.
