Patent number: 9748632Abstract: A wireless sensor includes an antenna, a sensing element, a tuning circuit, a processing module, a reference circuit block, and a transmitter. The tuning circuit adjusts the RF front-end to compensation for a change in a characteristic of the RF front end caused by the sensing element. The reference circuit block generates a signal based on a low voltage low frequency input that corresponds to a second environmental condition. The processing module generates a first digital value based on the adjustment to the RF front-end, where the first digital value is a representation of the first environmental condition, and generate a second digital value based on the signal, where the second digital value is a representation of the second environmental condition. The transmitter generates the outbound RF signal that includes at least one of the first and second digital values.Type: GrantFiled: March 27, 2017Date of Patent: August 29, 2017Assignee: RF Micron, Inc.Inventors: Shahriar Rokhsaz, Brian David Young, Ahmed Younis, John J.

Patent number: 9607188Abstract: A passive radio frequency identification (RFID) sensor is provided. This passive RFID sensor includes at least one antenna, at least one processing module, and a wireless communication module. The at least one antenna has an impedance that may vary with an environment in which the sensor is placed. Additionally, the antenna impedance might be permanently changed in response to an environmental variation or an event. The at least one processing module couples to the antenna and has a tuning module that may vary a reactive component impedance coupled to the antenna in order to change a system impedance. The system impedance includes both the antenna impedance and the reactive component impedance. The tuning module then produces an impedance value representative of the reactive component impedance. A memory module may store the impedance value which may then later be communicated to an RFID reader via the wireless communication module.Type: GrantFiled: September 29, 2015Date of Patent: March 28, 2017Assignee: RFMicron, Inc.Inventors: Shahriar Rokhsaz, Brian David Young, Ahmed Younis, John J.
