Wireless sensor reader assembly
First Claim
1. A system for wirelessly sensing a parameter from a remote location, comprising:
- a handheld reader device configured to communicate with a wireless sensor;
wherein said handheld reader device includes a plurality of modes to establish communication with said wireless sensor, said modes comprising;
a docked mode wherein said handheld reader device is not in use;
a search mode wherein said handheld reader device attempts to establish the proper distance acceptable for taking readings from the wireless sensor, wherein when said handheld reader device is in said search mode, said handheld reader device is configured to receive at least one response signal from said wireless sensor and compare a characteristic of said at least one response signal to a predetermined threshold value, wherein said comparison of said characteristic of the at least one response signal to said predetermined threshold value is used to determine to provide a feedback to a user of said handheld reader device; and
a read mode wherein said handheld reader device reads and samples response signals from the wireless sensor.

Abstract
Disclosed are a reader device, system, and method for communicating with a wireless sensor. The reader device may be configured to analyze the strength of a response signal transmitted from the wireless sensor in response to an excitation pulse generated by the reader device. In one embodiment, the reader device may be configured to engage be placed in a plurality of modes 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 wireless sensor to output a resonant signal. The reader device may receive the resonant signal from the wireless sensor and evaluate it against predetermined values. The evaluated signals may be used to assess the strength and the proximity of the reader device relative to the wireless sensor as it is implanted in a patient.
