Systems and methods for wireless power transmission

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

A method for controlling communication between wireless power transmitter managers is disclosed. According to some aspects of this embodiment, wireless power transmission system may include one or more wireless power transmitter managers and one or more wireless power receivers for powering various customer devices. A WiFi connection may be established between wireless power transmitter managers to share information between system devices. Wireless power transmitter manager may need to fulfill two conditions to control power transfer over a customer device; customer device's signal strength threshold has to be significantly greater than 50%, such as 55% or more of the signal strength measured by all other wireless power transmitter managers and has to remain significantly greater than 50% for a minimum amount of time.

System and method for controlling communication between wireless power transmitter managers

Video and audio signals are streamed to remote viewers that are connected to a communication network. A host server receives an originating video and audio signal that may arrive from a single source or from a plurality of independent sources. The host server provides any combination of the originating video and audio signals to viewers connected to a communication network. A viewer requests the host server provide a combination of video and audio signals from the host server. The host server transmits an instruction set to be executed by the viewer. The instruction set causes the viewer to transmit parameters to the host user, including parameters relating to the processing capabilities of the viewer. The host server then transmits multimedia data to the viewer according to the received parameters. A plurality of viewers may be simultaneously connected to the host server. Each of the plurality of viewers may configure the received video and audio signals independent of any other viewer and may generate alerts based on the video and audio content.

Method and apparatus for distributing multimedia to remote clients

The present invention may provide various electric receiver arrangements which may be used to provide wireless power transmission using suitable power transmission techniques such as pocket-forming. In some embodiments, receivers may include at least one antenna connected to at least one rectifier and one power converter. In other embodiments, receivers including a plurality of antennas, a plurality of rectifiers or a plurality of power converters may be provided. In addition, receivers may include communications components which may allow for communication to various electronic equipment including transmitters, phones, computers and others. Lastly, various implementation arrangements may be provided for including receivers in electronic devices.

Receivers for Wireless Power Transmission

In a system wherein one or more controllable camera(s) and one or more monitor(s) for displaying video information received from the camera(s) are connected to each other through a communication device, the states of all the cameras can be always understood at any monitor. Map management server software is provided to receive notification(s) of camera state information by all the cameras with the predetermined device, and to transmit the camera state information to all the monitors.

Communication apparatus, storage medium, camera and processing method

A camera control system has one or more cameras, power supply to which can be externally controlled, one or more camera management devices for managing the cameras, one or more terminal stations which communicate with the camera management devices to display images from the cameras, and an instruction device for generating a power turn-on/off instruction of an arbitrary one of the cameras from the terminal station

Camera control system and camera control apparatus

There is the possibility that the operator misunderstands as if an abnormality has occurred in an apparatus, depending on the state of reception of an image changing in accordance with situation. This problem is solved by providing a reception unit for receiving images generated from a plurality of communication terminals, an output unit for outputting the images received by the reception unit in order to dipslay the images on a display unit as multiple images, and a notification unit for grasping and notifying a state of reception of the images by the reception unit.

Communication apparatus and method, and storage medium

PROBLEM TO BE SOLVED: To make it possible to operate the on/off of a power supply for each camera from a remote place. SOLUTION: Power supply to each camera 16 can be externally controlled. An image receiving terminal 18 is provided with a button for turning on/off a power supply for a specified camera 16. When power supply off-operation is executed in the terminal 18, the terminal 18 transmits a power supply OFF request to a video transmitting terminal 12 connected to the corresponding camera 16 and the terminal 12 commands a camera controller 14 to turn off the power supply for the specified camera 16. When power supply on-operation is executed, the terminal 18 transmits power supply on request to the terminal 12 connected to the corresponding camera 16 and the terminal 12 commands the controller 14 to turn the specified camera 16 to a power supplied state.

Camera control system and its controller

PURPOSE: To efficiently transfer a message of multimedia. CONSTITUTION: When a message is transmitted from terminals A-J to another terminal via a mail processor 11, a transmission side terminal generates first the message. The message is generated by desired medium fitting in the throughput of the terminal. The mail processor 11, when receiving the message, stores a received message and checks the residual capacity of a mail box housing part 15, and converts the medium of received message by a conversion part 19 when it shows capacity less than prescribed capacity. For example, the conversion of the medium is performed in a direction to reduce information quantity such as by converting a voice to a character, a dynamic image to a still image, etc. Therefore, the mail processor can handle a large number of messages of multimedia even when the capacity of a mail box is limited.
