The present disclosure describes a methodology for wireless power transmission based on pocket-forming. This methodology may include one transmitter and at least one or more receivers, being the transmitter the source of energy and the receiver the device that is desired to charge or power. The transmitter may identify and locate the device to which the receiver is connected and thereafter aim pockets of energy to the device in order to power it. Pockets of energy may be generated through constructive and destructive interferences, which may create null-spaces and spots of pockets of energy ranged into one or more radii from transmitter. Such feature may enable wireless power transmission through a selective range, which may limit operation area of electronic devices and/or may avoid formation of pockets of energy near and/or over certain areas, objects and people.

Wireless power transmission with selective range

Configurations and methods of wireless power transmission for charging or powering one or more electronic devices inside a vehicle are disclosed. A transmitter capable of single or multiple pocket-forming may be connected to a car lighter, where this transmitter may include a circuitry module and an antenna array integrated within the transmitter, or operatively connected through a cable. This cable may allow the positioning of the antenna array in different locations inside the vehicle suitable for directing RF waves or pockets of energy towards one or more electronic devices. Transmitter's configuration can be accessed by one or more electronic devices through Bluetooth communication in order to set up charging or powering priorities.

Wireless charging and powering of electronic devices in a vehicle

The present disclosure may provide a wireless power system which may be used to provide wireless power transmission (WPT) while using suitable WPT techniques such as pocket-forming. Wireless power system may be used in a wireless powered house for providing power and charge to a plurality of mobile and non-mobile devices. Wireless powered house may include a single base station which may be connected to several transmitters. Base station may manage operation of every transmitter in an independently manner or may operate them as a single transmitter. Connection between base station and transmitters may be achieved through a plurality of techniques including wired connections and wireless connections.

Wireless powered house

The present disclosure describes a methodology for wireless power transmission based on multiple pocket-forming. This methodology may include one transmitter and two or more receivers, being the transmitter the source of energy and the receivers the devices that are desired to charge or power. Both devices, the transmitter and receiver, may communicate to each other via a wireless protocol. By communicating to each other, the transmitter may identify and locate the devices to which the receivers are connected and thereafter aim pockets of energy to each device in order to power them.

Methodology for multiple pocket-forming

The present disclosure describes a methodology for wireless power transmission based on pocket-forming. The method includes a transmitter device capable of forming pockets of energy used by a receiver device to charge an electronic device such as a computers, cell phones, tablet and/or devices of the like. The method may include using an array of antennas at the transmitter to locate the position of a receiver device. The transmitter may identify the position of the device by capturing a signal from a receiving device using two subsets from the array of antennas. The subset of antennas may then be adjusted to form pockets of energy at the appropriate location of the receiving device. Previously stored data pertaining to each antenna in the array may serve to determine the proper adjustments for the entire array of antennas based on the results from the subsets used to capture the receivers signal.

Method for 3 dimensional pocket-forming

There is provided a power supply receiver-transmitter device, a wireless power supply receiver, and a wireless power supply transmitter which allow wireless power supply transmission and wireless data transmission and reception, and improve the usability thereof. The wireless power supply receiver-transmitter device includes: a wireless power supply receiver (PR) including a power receiver unit (RU) and a first data transmitter/receiver unit (DRU); a wireless power supply transmitter (PT) including a power transmitter unit (TU); and a second data transmitter/receiver unit (DTU). The wireless power supply receiver (PR) wirelessly receives electric power transmitted from the wireless power supply transmitter (PT), and the first data transmitter/receiver unit (DRU) bidirectionally transmits and receives data to/from the second data transmitter/receiver units (DTU) through optical communications.

Permeable block and its manufacturing method

PROBLEM TO BE SOLVED: To provide a block having adequate water permeability for the purpose of relieving the heat is island phenomenon and is excellent in a water holding property, water-pickup property and strength an a method of manufacturing the same. SOLUTION: This block has open pores within a range from 10 to 40 vol.% and is characterized in that the open pores of 7 nm to 400 μm in diameter occupy >=30 vol.% of the open pores; the water holding rate ranges from 5 to 40 wt.%; the water permeability coefficient measured in compliance with JASS7 M-101 ranges from 1×10 to 1×10 cm/sec; and the bending strength is >=4 MPa.

Block and method of manufacturing the same

PROBLEM TO BE SOLVED: To provide a water-pervious ceramic block having excellent bending strength and superior in water permeability, and a method of producing the same. SOLUTION: This water-pervious ceramic block is obtained by adding water to a porcelainous aggregate having a maximum particle diameter of 5 mm or less and a mean particle diameter within the range of 1 to 3 mm, mixing them so as to cover the surface of the aggregate with water, gradually adding and mixing a non-plastic binder, further gradually adding and mixing a plastic binder to form a molding having the void ratio of 20% or more, and then firing the molding at a temperature within the range of 850 to 1,300 deg.C.

Water-pervious ceramic block and its production method

PROBLEM TO BE SOLVED: To provide an aggregate block and a block structure for planting that cause no trouble of fly soil, have reduced weight and high construction workability with load on the structure reduced and can realize natural resource saving by recycle and with low costs. SOLUTION: The objective aggregate block is produced by forming and solidifying inorganic granules as an aggregate which are light-weight and have continuous and/or closed voids inside and 0.21-1.6 specific gravity and >=95 wt.% of the inorganic granules have 1.7-19 mm particle sizes. Consequently, the block has continuous voids formed in the spaces between the aggregates. The objective block structure characteristically uses the aggregate block as a plate supporter.
