Abstract
Communication systems and methods for dynamically controlling the power wirelessly delivered by a remote reader unit to separate sensing device, such as a device adapted to monitor a physiological parameter within a living body, including but not limited to intraocular pressure, intracranial pressure (ICP), and cardiovascular pressures that can be measured to assist in diagnosing and monitoring various diseases. The communication method entails electromagnetically delivering power from at least one telemetry antenna within the reader unit to at least one telemetry antenna within the sensing device, and controlling the power supplied to the sensing device within a predetermined operating power level range of the sensing device.
