Description

[Background technology]

[0001] Many electronic devices are battery-powered. Rechargeable batteries eliminate the cost of replacing traditional dry-cell batteries. However, traditional rechargeable battery chargers are often used to avoid overcharging and save valuable resources. To use it to charge the battery, you must have access to an alternating current (AC) power outlet. This is sometimes unavailable or inconvenient. Therefore, It is preferable to power it with

"Anytime Beaconing in a Wireless Power r Transmission System (Conventional in wireless power transmission system) This application claims priority to U.S. Provisional Patent Application No. 62 / 583,323, entitled "Synchronous Beacon Transmission." , and benefit from it.

[0003] In the field of wireless charging, safe and reliable use in business or home environments To date, wireless charging has been limited to magnetic or inductive charging-based solutions. Unfortunately, these solutions have limited the use of wireless power The transmitting system and receiver must be in contact with or very close to each other. For wireless power transmissions that are not very close together, e.g., radio frequency (RF) signals More advanced mechanisms such as transmission via a laser, ultrasonic transmission, and laser power supply are required, but each of these is commercially available. There are some inherent hurdles to achieving commercial success.

[0004] The most viable systems to date utilize power transmission via RF. In typical residential, commercial, or other residential RF transmission situations, the transmitted signal There are many reasons to limit RF exposure levels in signals. As a result, power supplies must be relatively low power. This low energy transfer rate limits the efficiency of the system. It is essential.

[0005] The typical method for providing signals to clients is through a master bus controller. tells the client when to transmit beacons and directs the antenna elements to receive beacons. This involves directing when to take samples of the signal to determine the complex phase. The master bus controller calculates the complex conjugates for the antenna elements and transmits the results to the The force signal is stored as a path to the client that provides the force signal to the client. The master bus controller then sends the next time slot to the next client. In this system, clients can receive power signals in designated time slots. The timing of client communication is determined by the master bus controller. This method does not require the master bus controller, This requires a lot of communication between the container board and the client. reduces the available time slots that can be used for additional power.

[0006] Another typical approach is for the master bus controller to determine the clock speed for the subsequent time interval. The client power schedule is calculated in advance and the schedule is transmitted to the client and the antenna. This way, the master bus controller sends Assign start times and pre-arranged beacon schedules to determine which clients are This method determines whether to receive a powered signal in a time slot. It is more time-efficient than the conventional method, but it eliminates the time slots that might have been used to transmit power signals. , are assigned to the transmission of communications containing a pre-prepared schedule. In this case, the client has no control over the transmission system from which it receives power. Even if a client is listening to a beacon or receiving a powered beacon, it cannot move or The client knows when the communication beacon is sent and can roam. It is necessary to be able to obtain the power that was available based on the time schedule. So it's basically an active powered receiver.

Some exemplary echo cancellation techniques require echo cancellation in dB. Calibration is used to cancel and filter received and transmitted signals to Adjusts the phase and amplitude of the cell path to match the transmission leakage at the center frequency. One proposed method for widening the width is to use the time domain inverse Fourier transform to Reveal the main leakage paths resulting from finite separation through the antenna and signal reflection from the antenna The method then uses an adaptive filter to calculate the time domain inverse response of the leakage path. and track the time-varying response. Cancellation is performed using tap adaptive filters, analog radio frequency By using multiple cancellers, damping capacitors, and connecting the cancellers to the output matching network, Further improvement can be achieved by installing it on the differential low impedance side of the network. If the system detects a small difference between the power it sends and the power it receives, it will use out-of-band filtering. Using this, you can get 100+ dB of isolation between receive and transmit RF, providing good isolation. It is possible to maintain an acceptable phase relationship with the engine.
