摘要： A label sensor that can be affixed to an item includes a first section and a second section. The first section includes a memory, an environmental sensor, a radio frequency (RF) front end, and a processing module. The processing module is operably coupled to the memory, the environmental sensor, and the RF front end. The second section includes an activation circuit that is operable, upon receiving an input, to activate one or more of the memory, the environmental sensor, the RF front end and the processing module. The activation causes the label sensor to be put in an operational mode of a plurality of operational modes.

摘要： A wireless sensor includes a radio frequency (RF) receiving circuit operable to receive an RF signal having a carrier frequency of a plurality of carrier frequencies. The RF receiving circuit further includes a variable impedance where impedance of the variable impedance is a factor in establishing a resonant frequency of the RF receiving circuit. The wireless sensor further includes a processing module that is operable to determine a first value for a first impedance of the variable impedance for a known temperature based on the resonant frequency and the carrier frequency, determine a second value a second impedance of the variable impedance for an unknown temperature based on the resonant frequency and the carrier frequency, and determine a difference between the first and second values that corresponds to a change between the known temperature and the unknown temperature.

摘要： 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.

摘要： A method begins by detecting a variance of one or more RF characteristics of a wireless sensor from a desired value of the one or more RF characteristics, due to exposure to an environmental condition. The tuning circuit is operably coupled to an antenna that includes a tail section that is located in a radio frequency (RF) limited area, and a head section that is located in a non-RF limited area. The method continues by adjusting the tuning circuit in response to the detecting of the variance. The method continues by generating a message regarding the adjusting of the tuning circuit, wherein a level of the adjusting of the tuning circuit is representative of the variance of the one or more RF characteristics sensed by the tail section. The method continues by transmitting the message to one or more of an RF reader and a computing device.

摘要： 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.
