Remote charging system
First Claim
1. A consumer device configured and operable for communicating with a charging device, wherein the charging device comprises a transmitter unit associated with an antenna unit comprising a power antenna configured to define at least one charging zone for transmitting charging power to said at least one charging zone, a receiver for receiving signals from consumers located within said charging zone, and a controller unit, said controller being configured and operable to be responsive to a request signal from a consumer indicative of demand for charging to initiate a charging process of the consumer by radiation from the antenna unit toward said consumer to supply power required for operating a functional unit of said consumer, the consumer device comprising:
- a functional unit requiring electric power for operation, and a communication unit comprising a consumer controller, an antenna unit for receiving electromagnetic radiation from surroundings and generating electric output, and a harvester circuit configured for receiving the electric output of the antenna unit and transferring corresponding power to an energy storage unit associated with said functional unit, the consumer controller being configured and operable for generating a request signal addressed to the remote charging device indicative of a demand for charging said energy storage unit.

Abstract
A charging device is provided for communicating with one or more consumer devices for remotely charging at least one of them upon demand of the consumer. The charging device comprises a transmitter unit associated with an antenna unit comprising a power antenna for defining at least one charging zone for transmitting charging power toward it; a receiver for receiving signals from consumers located within the charging zone; and a controller unit configured to be responsive to a request signal from a consumer indicative of demand for charging, to initiate a charging process of the consumer by radiation from the power antenna toward the consumer to supply power required for operating a functional unit of the consumer. The power antenna may comprise an array of directional antenna elements, each defining the charging zone within a different angular segment of entire charging space defined by a radiation pattern of the antenna array.

6. A charging system for remotely charging multiple consumer devices upon demand from the consumer devices, the system comprising:
-
at least one charging device comprising a transmitter unit associated with an antenna unit comprising a power antenna configured to define at least one charging zone for transmitting charging power to said at least one charging zone, a receiver for receiving signals from consumers located within said charging zone, and a controller unit, said controller being configured and operable to be responsive to a request signal from a consumer indicative of demand for charging to initiate a charging process of the consumer by radiation from the antenna unit toward said consumer to supply power required for operating a functional unit of said consumer; and at least one consumer device being a subscriber of said at least one charging device, the consumer device comprising a functional unit requiring electric power for operation, and a communication unit comprising a controller unit, an antenna unit for receiving electromagnetic radiation from surroundings and generating electric output, and a harvester circuit configured for receiving the electric output of the antenna unit and transferring corresponding power to an energy storage unit associated with said functional unit, the controller unit being configured and operable for generating the request signal addressed to said at least one remote charging device indicative of a demand for charging said energy storage unit, and for identifying a position of the consumer from the received request signal by identifying its distance and its relative angle from the receiver. - View Dependent Claims (7, 8, 9, 10, 11, 12)
