The present invention provides a system for operating a power line communications system that employs surface wave communications and conducted communications. The system is comprised of a plurality of network elements, which may take the form of repeaters, communication interface devices, backhaul devices, medium voltage transducers, distribution points, aggregation points, and others. In one embodiment, surface waves are communicated over the medium voltage power lines and the conducted communications are communicated via the low voltage power lines to and from customer premises.

A method and repeater are described for repeating using a time division duplex (TDD) radio protocol. A signal is transmitted from a first station to a second station using a downlink and an uplink. The signal can be detected on the uplink or the downlink. The repeater can synchronize to time intervals associated with the detected signal that are measured during an observation period. The signal can be retransmitted from the second station to the first station if the signal is detected on the uplink and re-transmitted from the first station to the second station if the signal is detected on the downlink. A gain value associated with the downlink can be used to establish a gain value associated with the uplink.

A plurality of content providers provide multiple resources to multiple clients. At least some of said resources are to be served to clients from a shared content delivery network (CDN) formed by a plurality of repeater servers. Each content provider provides at least some resources via one or more content sources associated with that content provider. Amounts of data transmitted by the CDN on behalf of each of the plurality of content providers are monitored. Based at least in part on said monitoring, requests for resources are selectively delivered at a lower transmission rate. The lower transmission rate is achieved by generating pauses or delays in the transmission.

Systems and methods for monitoring conditions are provided. A system can comprise a plurality of wireless transmitters and a plurality of repeaters. At least one wireless transmitter can be integrated into an alarm. The repeaters can be dispersed throughout a region at defined locations. The system can also include a computer to receive information communicated from the repeaters and the transmitters. The computer can include software for evaluating received information, identifying an alarm condition and an originating location of the alarm condition, and for reporting the alarm condition to a remote location. Other embodiments are also claimed and described.

Described herein are improved configurations for a wireless power transfer. Described are methods and designs for implantable electronics and devices. Wireless energy transfer is utilized to eliminate cords and power cables puncturing the skin to power an implantable device. Repeater resonators are employed to improve the power transfer characteristics between the source and the device resonators.

The present invention provides an amplifying repeater, which is constructed in such a manner that a ferrite core is inserted into a coil with a pre-determined number of winds to increase an induced electromotive force caused by an increase in flux linkage using a time-varying magnetic field of electromagnetic waves at a position distant from various electromagnetic wave generating sources by a predetermined distance and the induction coil and a variable condenser for inducing resonance are connected to each other to increase current while reducing a resistant component existing in the induction coil to intensify and amplify the magnetic field of electromagnetic waves. Furthermore, the present invention provides a wireless power conversion charging device using the magnetic field of electromagnetic waves, which is located between an electromagnetic wave generating source transmitter and a receiving coil or attached to the transmitter and receiving coil. The wireless power conversion charging device includes a rectifying diode for rectifying an electromotive force induced in a construction in which a resonance and impedance matching variable condenser is connected to a coil in series or in parallel in order to transmit maximum induced power to a charging battery that is a load using electromagnetic waves amplified by the amplifying repeater, and a smoothing condenser for smoothing the rectified voltage. Accordingly, charging power required for various small power electronic devices can be provided and power can be supplied to various loads.

Resource requests made by clients of origin servers in a network are intercepted by reflector mechanisms and selectively reflected to other servers called repeaters. The reflectors select a best repeater from a set of possible repeaters and redirect the client to the selected best repeater. The client then makes the request of the selected best repeater. The resource is possibly rewritten to replace at least some of the resource identifiers contained therein with modified resource identifiers designating the repeater instead of the origin server.

The present invention relates to a wireless home automation system having a controller for controlling a broad variety of functions via two ways communication with a plurality of devices. The controllers and devices of the system comprises means for generating a signal comprising a destination identifier, instructions related to the input / output of the destination or source device, and a repeater identifier. The devices according to the invention are adapted to act as input / output devices and signal repeating devices. The processors of each device comprises means for, upon reception of a signal, processing said information if the destination identifier corresponds to the device identifier of the device, and means for, upon reception of a signal, transmitting a second signal holding at least said destination identifier and said instruction if the repeater identifier corresponds to the device identifier of the device.

A PLCS network element that provides communications to one or more user devices and may also repeat data for other network elements is provided. In one embodiment, the device includes software for discovering its upstream gateway, for acting as a gateway for other devices, and for relaying DHCP transmissions. In addition, the device includes software for receiving and processing commands from a remote computer system that may include commands enabling and disabling the repeater functionality. Finally, the device may also include software for receiving and processing configuration information that may include, for example, information of the other network devices for which it will repeat.
