    • A radio frequency identification (RFID) device has controllable features that allow for modification of its interaction with external devices, such as RFID readers. A chip of the RFID device the chip may include control logic that controls outgoing signals sent by the RFID device at least in part based on one or more of 1) a non-informational characteristic of incoming signals received by the RFID device, and 2) environment information received by an environment sensor of the RFID device. The RFID device may be controlled by adjusting an adjustable modulator within the device. The modulator may adjust outgoing signals from the RFID device to an appropriate level of signal strength, or to have other suitable characteristics. By control of the modulator settings of the RFID device, adjustments in performance of the RFID device may be made for suitable operation in a variety of situations and environments.

    • A system and device for harvesting various frequencies and polarizations of ambient radio frequency (RF) electromagnetic (EM) energy for making a passive sensor (tag) into an autonomous passive sensor (tag) adapted to collect and store data with time-stamping and some primitive computation when necessary even when an interrogating radio frequency identification (RFID) reader is not present (not transmitting). A specific source of ambient RF EM energy may include wireless fidelity (WiFi) and/or cellular telephone base stations. The system and device may also allow for the recharging of energy storage units in active and battery assisted passive (BAP) devices. The system could be a "smart building" that uses passive sensors with RF EM energy harvesting capability to sense environmental variables, security breaches, as well as information from "smart appliances" that can be used for a variety of controls and can be accessed locally or remotely over the Internet or cellular networks.
