With the systems, devices, and methods, power can be wirelessly transmitted effectively and efficiently.
Claims17
A system for wirelessly transmitting power, comprising:
- (a) a receiver;
- and
- (b) a power transmitting device for wirelessly transmitting power to the receiver, wherein the power transmitting device comprises:
- (i) a transmitter layer;
- (ii) a sensor layer provided on or over the transmitter layer and including one or more sensors;
- and
- (iii) a cover disposed on and supported by the one or more sensors, wherein the cover is sectionalized with a plurality of tiles,
- wherein, in response to the receiver being placed on the cover, the sensor layer detects on which tile or tiles among the plurality of tiles the receiver is placed based on a pressure due to the receiver, and subsequently, the transmitter layer within the corresponding tile or tiles transmits ping signals, thereby determining a location of the receiver within the corresponding tile or tiles.
A power transmitting device for wirelessly transmitting power to a power receiving device, the power transmitting device comprising:
- (i) a transmitter layer including a plurality of transmitting devices;
- (ii) a sensor layer provided on or over the transmitter layer and including one or more sensors;
- and
- (iii) a cover layer provided on or over the sensor layer,
- wherein a number of sensors included in the sensor layer is less than a number of transmitting devices included in the transmitter layer such that the sensors are configured to determine an approximate location of the power receiving device and the transmitting devices are configured to determine a more precise location of the power receiving device.
A method for wirelessly charging one or more power receiving devices, the method comprising the steps of:
- monitoring mechanical pressure applied to a cover of a power transmitting device and converting the mechanical pressure to an electrical signal or signals;
- determining whether the mechanical pressure is due to one or more objects placed on the cover of the power transmitting device or due to transient noise, by analyzing the electrical signal or signals;
- in response to determining that the mechanical pressure is due to one or more objects placed on the cover of the power transmitting device, scanning corresponding locations of the sensors by sending analog ping signals;
- determining whether the power transmitting device receives a response or responses from the one or more objects in a pre-determined time period;
- in response to the determination that the power transmitting device receives a response or responses from the one or more objects in the pre-determined time period, determining that the one or more objects comprise a power receiving device or devices;
- and
- transmitting power to the power receiving device or devices for wireless charging.
