摘要： A method for determining a physical property of an object or fluid in a dynamic multi-path clutter environment comprises transmitting an RF interrogation signal to a wireless sensor physically coupled to the object or fluid (gas or liquid) in the dynamic multi-path clutter environment, wherein the wireless sensor is operable to receive the RF interrogation signal, produce a reference signal and a measurement signal, and retransmit the reference signal and the measurement signal in the dynamic multi-path clutter environment. The reference signal and measurement signal are delayed by the wireless sensor by an amount of time that may be a function of the unknown physical property. The method also comprises receiving the retransmitted reference signal and the retransmitted measurement signal and comparing them in the time domain in order to determine the unknown physical property of the object or fluid. The method further comprises setting the time delays of the retransmitted reference and retransmitted measurement signals to be long enough for the ringdown time to be over but not so long so that the differential time is distorted by the dynamics of the system.

摘要： An antenna made up of addressable conductive segments, or pixel elements, affixed to the top of each piston in a piston array is presented. The pixel elements can be activated in less than a millisecond to form an antenna array and transmission line pattern using movable pistons and a two-dimensional actuator. Each piston comprises a handle, a bottom conductive segment affixed to the top of the handle, a dielectric segment affixed to the uppermost surface of the bottom conductive segment, and a top conductive segment affixed to the uppermost surface of the dielectric segment. When the piston is not actuated, the top conductive segment forms part of a ground plane. The top conductive segment form part of the transmission line and antenna array patterns, the dielectric segment becomes a dielectric space and the bottom conductive segment forms part of the ground plane when the piston is actuated.

摘要： A method for determining a physical property of a structural member in a dynamic multi-path clutter environment is given. The method comprises transmitting an RF interrogation signal to a wireless sensor operable to receive the RF interrogation signal, produce a reference signal and a measurement signal, and transmit the reference signal and the measurement signal in the dynamic multi-path clutter environment. The reference signal is delayed by a first time delay and the measurement signal is delayed by a second time delay that is a function of the physical property to be determined. The first and second time delays are associated by a known relationship defined by the wireless sensor. The method further comprises receiving the transmitted reference signal and the transmitted measurement signal and comparing the transmitted reference signal and the transmitted measurement signal in the time domain. Finally, the method comprises using this comparison to determine the physical property of the structural member.
