Abstract: A radio frequency identification (RFID) tag includes a power harvesting circuit that operates generate power for the RFID tag from a continuous wave of a radio frequency (RF) signal. The RFID tag further includes a tuning circuit that is tuned based on a capacitance setting, where the capacitance setting is indicative of a power level of the power. The RFID tag further includes a processing module operably coupled to the tuning circuit, where the processing module operates to generate the capacitance setting to obtain a desired power level for the power.

Abstract: A wireless sensor includes a radio frequency (RF) front end, a sensing element, and a processing module. The RF front end sends a coded digital value to a sensing computing device via an RF signal. The sensing element senses an environmental condition of an item. The processing module determines an effect on an operational parameter of an RF front end of the wireless sensor as a result of the sensing element sensing the environmental condition. The processing module also adjusts tuning of the RF front end to mitigate the effect on the operational parameter and equates an amount of adjusting of the tuning of the RF front end to the coded digital value.

Abstract: A method includes sending, by a reader, a radio frequency (RF) signal to a wireless sensor that includes an antenna having a tail section and a head section. The tail section is for placement in an RF limited area for sensing moisture in a first location of a vehicle under test and wherein the head section is for placement in a non-RF limited area. The method further includes receiving, by the reader, an RF response to the RF signal from the wireless sensor. The first RF response includes an indication of adjustment of one or more RF characteristics of the wireless sensor, which corresponds to a variance of the one or more RF characteristics from a desired value, which, in turn, corresponds to a level of moisture at the first location. The method further includes outputting, by the reader, a message regarding the level of moisture at the first location.

Abstract: A wireless sensor includes a radio frequency (RF) front end, a sensing element, and a processing module. The RF front end receives a request for sensed data from a sensing computing device and sends a coded digital value to the sensing computing device via the RF signal. The sensing element senses an environmental condition of an item. The processing module determines an effect on an operational parameter of an RF front end of the wireless sensor as a result of the sensing element sensing the environmental condition and while receiving the RF signal. The processing module also adjusts tuning of the RF front end to mitigate the effect on the operational parameter and equates an amount of adjusting of the tuning of the RF front end to a coded digital value.

Abstract: A method begins by a first radio frequency identification (RFID) sensor, that is associated with a first object element, receiving a first data request signal from an RFID reader and sending a first radio frequency (RF) signal that includes first data to the RFID reader in response to the first data request signal. The method continues with a second RFID sensor receiving a second data request signal from, and sending second data to, the RFID reader. The method continues with the RFID reader sending a representation of the first and second data to a data processing unit, which processes the representation of the first and second data to determine a first and second data point regarding first and second object elements. The method continues by the data processing unit processing the first and second data points to determine an environmental relationship between the first and second object elements.

Abstract: A pressure sensing circuit for use with a wireless sensor that includes an antenna and a pressure sensing element. The antenna includes a first pole and a second pole and is operable to transceive radio frequency signals between the wireless sensor and a wireless data collecting device. The pressure sensing element includes an electrical circuit and a diaphragm. When pressure is applied to the diaphragm, a characteristic of the electrical circuit changes. The changing of the characteristic of the electrical circuit causes one or more RF characteristics of the wireless sensor to change, which is interpretable to determine a pressure being applied to the pressure sensing element.
