Remotely-powered sensing system with multiple sensing devices

A sensing system comprising:

• an interface device;
• a shared communication device connected to the interface device;
• a first analyte sensing device connected to the shared communication device and configured to:
• receive an unaddressed measurement command via the interface device and the shared communication device,
• perform a measurement sequence in response to receiving the unaddressed measurement command,
• receive an addressed read measurement data command via the interface device and the shared communication device,
• determine whether the addressed read measurement data command is addressed to the first analyte sensing device,
• if the addressed read measurement data command is determined to be addressed to the first analyte sensing device, convey measurement data via the shared communication device and interface device;
• and
• if the addressed read measurement data command is determined to be not addressed to the first analyte sensing device, not convey measurement data in response to the addressed read measurement data command;
• and
• a second analyte sensing device connected to the shared communication device and configured to:
• receive the unaddressed measurement command via the interface device and the shared communication device,
• perform a measurement sequence in response to receiving the unaddressed measurement command,
• receive the addressed read measurement data command via the interface device and the shared communication device,
• determine whether the addressed read measurement data command is addressed to the second analyte sensing device,
• if the addressed read measurement data command is determined to be addressed to the second analyte sensing device, convey measurement data via the shared communication device and interface device;
• and
• if the addressed read measurement data command is determined to be not addressed to the second analyte sensing device, not convey measurement data in response to the addressed read measurement data command.

A method comprising:

• receiving an unaddressed measurement command at first and second analyte sensing devices of a sensing system via an interface device and shared communication device of the sensing system;
• using the first analyte sensing device to perform a measurement sequence in response to receiving the unaddressed measurement command;
• using the second analyte sensing device to perform a measurement sequence in response to receiving the unaddressed measurement command;
• receiving an addressed read measurement data command at the first and second analyte sensing devices of the sensing system via the interface device and the shared communication device of the sensing system;
• using the first analyte sensing device to determine whether the addressed read measurement data command is addressed to the first analyte sensing device;
• using the first analyte sensing device to convey measurement data if the first analyte sensing device determines that the addressed read measurement data command is addressed to the first analyte sensing device, wherein the first analyte sensing device does not convey measurement data if the first analyte sensing device determines that the addressed read measurement data command is not addressed to the first analyte sensing device;
• using the second analyte sensing device to determine whether the addressed read measurement data command is addressed to the second analyte sensing device;
• and
• using the second analyte sensing device to convey measurement data if the second analyte sensing device determines that the addressed read measurement data command is addressed to the second analyte sensing device, wherein the second analyte sensing device does not convey measurement data if the second analyte sensing device determines that the addressed read measurement data command is not addressed to the second analyte sensing device.
