METHOD AND APPARATUS FOR SENSING AN ENVIRONMENTAL CONDITION DURING FREQUENCY HOPPING
First Claim
1. A method for execution by a wireless sensor, the method comprises:
- receiving a series of radio frequency (RF) signals, wherein, from RF signal to RF signal of the series of RF signals, a carrier frequency is changed in accordance with a frequency hopping pattern; and
while receiving the series of RF signals, sensing an environmental condition by;
for a frequency hop of at least some frequency hops of the frequency hopping pattern;
adjusting a characteristic of the wireless sensor to maintain proximal alignment of a resonant frequency of the wireless sensor with the carrier frequency corresponding to a present frequency of the at least some frequency hops; and
generating a value to represent the adjustment of the characteristic, wherein a set of values is generated for the at least some frequency hops, wherein the set of values is used to determine a sensed value of the environmental condition.

Abstract
A method includes receiving a series of radio frequency (RF) signals, where, from RF signal to RF signal of the series of RF signals, a carrier frequency is changed in accordance with a frequency hopping pattern. The method further includes, while receiving the series of RF signals, sensing an environmental condition by, for a frequency hop of at least some frequency hops of the frequency hopping pattern, adjusting a characteristic of a wireless sensor to maintain proximal alignment of a resonant frequency of the wireless sensor with the carrier frequency corresponding to a present frequency of the at least some frequency hops and generating a value to represent the adjustment of the characteristic, where a set of values is generated for the at least some frequency hops and where the set of values is used to determine a sensed value of the environmental condition.
