Methods, systems, and apparatus for automatic RF power transmission and single antenna energy harvesting
First Claim
1. A system, comprising:
- a transmitter having a first mode and a second mode, the transmitter configured to repeatedly send a number of discrete first wireless signals in the first mode, each wireless signal of the first wireless signals having a power level and carrying transmitter identification information uniquely associated with the transmitter, the transmitter configured, when in the second mode, to send a second wireless signal having a power level and carrying the transmitter identification information; and
a receiver configured to receive a wireless signal of the first wireless signals such that the receiver is activated by the wireless signal of the first wireless signal, the receiver configured, in response to receiving the wireless signal of the first wireless signals, to send a third wireless signal carrying the transmitter identification information to the transmitter,the transmitter configured to transition from the first mode to the second mode in response to receiving the third wireless signal and determining that the third wireless signal includes the transmitter identification information uniquely associated with the transmitter.

Abstract
In some embodiments, a transmitter has a first mode and a second mode. The transmitter is configured to repeatedly send discrete first wireless signals carrying transmitter identification information uniquely associated with the transmitter in the first mode and to send a second wireless signal carrying the transmitter identification information in the second mode. A receiver is configured to receive a wireless signal of the first wireless signals such that the receiver is activated by the wireless signal of the first wireless signal and, in response to receiving the wireless signal of the first wireless signals, to send a third wireless signal carrying the transmitter identification information to the transmitter. The transmitter is configured to transition from the first mode to the second mode in response to receiving the third wireless signal and determining that the third wireless signal includes the transmitter identification information uniquely associated with the transmitter.

13. A system, comprising:
-
a receiver configured to send a first wireless signal to a transmitter, the first wireless signal including a request for power, the receiver configured, upon receiving a second signal including transmitter identification information, to send a third wireless signal including the transmitter identification information; and a transmitter configured to activate in response to receiving the first wireless signal such that the transmitter sends a second wireless signal having a power level and carrying transmitter identification information uniquely associated with the transmitter, the transmitter configured to send the second wireless signal until a predetermined time duration of a timeout timer of the transmitter elapses, the timeout timer configured to start when the transmitter receives the first wireless signal, the timeout timer configured to restart upon the transmitter receiving the third wireless signal carrying the transmitter identification information. - View Dependent Claims (14, 15, 16)

17. A method, comprising:
-
sending, by a receiver at a first time, a first wireless signal including a request for power; receiving, by a transmitter, the first wireless signal; sending, by the transmitter at a second time after the first time, a second wireless signal having a power level and carrying transmitter identification information, the transmitter continuing to send the second wireless signal until a timeout timer of the transmitter reaches a predetermined time threshold; receiving, by the receiver, the second wireless signal such that at least one of the receiver is powered by the second wireless signal or an energy storage level of an energy storage device coupled to the receiver is increased; and sending, by the receiver at a third time after the second time, in response to receiving the second wireless signal from the transmitter, a third wireless signal including the transmitter identification information repetitively, the timeout timer of the transmitter being reset upon receiving the third wireless signal. - View Dependent Claims (18, 19, 20, 21)
