Self test device and method for wireless sensor reader
First Claim
1. A system for wirelessly sensing a parameter from a remote location, comprising:
- a reader device configured to communicate with a wireless sensor;
a docking station for communicating with the reader device;
a self-test device which emulates at least one electrical behavior of said wireless sensor in a known manner and is configured to adjust its resonant frequency to emulate said wireless sensor when placed in communication with said reader device;
wherein said system is configured to carry out a self test such that said reader device wirelessly communicates with said self-test device and obtains at least one response from said self-test device, and;
wherein said at least one response is compared to an expected response from said self-test device, in order to assess a functional performance of said reader.

Abstract
Disclosed is a self-test device and method for assessing the functional performance of a reader device that is configured to interface with a wireless sensor. The self-test device may be configured to analyze the accuracy of a signal transmitted from the reader device or the accuracy of a signal received by the reader device. In one embodiment, the reader device may be configured to engage the self-test device to allow the reader to transmit a signal, such as a short pulse of energy or a short burst of radio frequency energy to cause the self-test device to output a resonant signal. The self-test device may receive the transmit signal from the reader and evaluate it against predetermined values. The evaluated signals may be used to assess the accuracy of the transmit signal of the reader device to identify potential calibration issues and initiate remedial action by an automated system or human intervention if needed. The self-test device may be built into a docking station where the reader is placed when not in use.
