Abstract
Techniques are described herein for enabling, among other features, more effective wireless charging of devices in wireless power delivery environments through enhanced signal focusing over multiple paths in a multipath wireless power delivery environment. More specifically, the systems and methods discussed herein describe techniques for increasing effective charging of devices, including enhanced ability to focus charging utilizing multiple pathways, phase detection of incoming signals allowing for movement detection in a wireless environment, phase synchronization, and directional arrays.
Claims16
A method comprising:
- receiving, by an antenna, an incoming signal transmitted from a client device over a first path and at least a second path in a multipath wireless environment,
- wherein the incoming signal is received via the first path and the at least a second path with differing phases and arrival times;
- identifying phase and timing information corresponding to the incoming signal received by the antenna via the first path and the at least a second path;
- determining transmission settings for the antenna based on the phase and timing information to facilitate inversing the timing information for transmission of a sequence of response signals from the antenna to, and focused on, the client device over a reverse of the first path and the at least a second path;
- and
- transmitting, by the antenna and according to the transmission settings, the sequence of response signals to the client device over the reverse of the first path and the at least a second path for simultaneous reception of the sequence of response signals by the client device.
A transceiver comprising:
- an antenna configured to receive an incoming signal transmitted from a client device over a first and at least a second path in a multipath wireless environment,
- wherein the antenna is capable of receiving the incoming signal via the first path and the at least a second path with differing phases and arrival times;
- and
- control circuitry configured to:
- identify timing information corresponding to the incoming signal received via the first and the at least a second path;
- determine transmission settings based on the timing information to facilitate inversing the timing information for simultaneous reception of a sequence of response signals by, and focused on, the client device over a reverse of the first path and the at least a second path;
- and
- cause the antenna to transmit, according to the transmission settings, the sequence of response signals to the client device over the reverse of the first path and the at least a second path.
One or more non-transitory computer readable storage media having instruction code stored thereon which when executed by one or more processors causes a machine to:
- receive, by an antenna, an incoming signal transmitted from a client device over a first path and at least a second path in a multipath wireless environment,
- wherein the incoming signal is received via the first path and the at least a second path with differing phases and arrival times;
- identify phase and timing information corresponding to the incoming signal received by the antenna via the first path and the at least a second path;
- determine transmission settings for the antenna based on the phase and timing information to facilitate inversing the timing information for transmission of a sequence of response signals from the antenna to, and focused on, the client device over a reverse of the first path and the at least a second path;
- and
- direct the antenna to transmit, according to the transmission settings, the sequence of response signals to the client device over the reverse of the first path and the at least a second path for simultaneous reception of the sequence of response signals by the client device.
