摘要： A reader apparatus with software-controller power exciter, and methods for operating the same to wirelessly interrogate an environmental or structural sensor are disclosed. Some aspects of the application are directed to a reader apparatus that transmits high power for a fast cold start of a sensor and subsequently switch to low power transmission in response to an indication signal received from the sensor indicating that a state of charge of the sensor has reached a threshold value such that high power transmission is no longer necessary, thereby extending battery life of the reader apparatus.

摘要： A pair of programmable state machines may be included in a transmitter integrated circuit of a scanner (e.g. a body scanner) to control the sub-circuits of the transmitter integrated circuit. The first programmable state machine may be used to control the signal processor of the transmitter that facilitates generation of a signal to be transmitted at a target, such as a user to be scanned. The second programmable state machine may be used to control the transmitter's selection of a transmission channel for transmitting the signal in which provides the signal to be transmitted to an antenna. Further, the receiver integrated circuit of the scanner may include a similar pair of programmable state machines for controlling the receive signal processor and receiver of the receiver integrated circuit. The inclusion of the state machines can reduce both the scan time and the circuit complexity of the scanner.
