Support of coexistence of wireless transmission equipment in shared wireless medium environments is disclosed, which is applicable to various types of wireless transmission equipment. For instance, a wireless power transmission system (WPTS) delivers power to wireless power receiver clients via transmission of wireless power signals using one or more frequencies and/or channels within shared wireless medium environments in which other wireless equipment is operating, such as access points and stations in wireless local area networks (WLANs). The WPTS is configured to co-exist with the operations of the other wireless equipment within the shared wireless medium environment by adapting its transmission operations to utilize frequencies or channels that do not interfere with other equipment and/or implementing co-channel and shared channels operations under which access to channels is implemented using standardized WLAN protocols such as PHY and MAC protocols used for 802.11 (Wi-Fi™) networks.

Wireless transmission in shared wireless medium environments

Methods and apparatus for detecting and handling evil twin access points (APs). The method and apparatus employ trusted beacons including security tokens that are broadcast by trusted APs. An Evil twin AP masquerades as a trusted AP by broadcasting beacons having the same SSID as the trusted AP, as well as other header field and information elements IE in the beacon frame body containing identical information. A sniffer on the trusted AP or in another AP that is part of a Trusted Wireless Environment (TWE) receives the beacons broadcasts by other APs in the TWE including potential evil twin APs. The content in the header and one or more IEs in received beacons are examined to determine whether a beacon is being broadcast by an evil twin. Detection of the evil twin are made by one of more of differences in MAC addresses of trusted and untrusted beacons, time jitter measurements and replay detection using timestamps in the beacons, detection of missing security tokens in untrusted beacons and detection that a security token that is mimicked by an evil twin is invalid. In one aspect, the security token is stored in a vendor-specific IE in trusted beacons that is generated by employing a secret key using a cryptographic operation operating on data in the beacon prior to the vendor-specific IE.

Wireless transmission in shared wireless medium environments using multiple PHYs

Various embodiments use prospective synchronization signals early in the signal reception to adjust framing cycles of communication nodes to reduce jitter. Some embodiments temporarily suspend messaging between existing nodes of a communication system while instructing new nodes to generate a beacon according to a beacon schedule. The system can monitor for responses from the new node and calculate a timing error. This timing error can be sent to the new node to adjust cycle framing. In some embodiments, these techniques for timing the receive (Rx) and transmission (Tx) cycles of a node (e.g., a client wireless antenna system) can be utilized such that the radio frequency (RF) energy received between RF energy cycles can be delivered directly to the node, stored in a client's battery by a wireless charging system, enhance the Rx signal opportunities, or make the integrity of the delivered Tx signal more efficient.

Low jitter event synchronization across communication links

Multiple video game players access an encrypted video game library stored on a shared mass storage device. A multiplexer multiplexes data read from the mass storage device to provide output streams to multiple video game playing units consuming video game instructions. A secure bus communicates video game instructions from the shared mass storage device to each of the video game playing units. Video game software or other entertainment content is distributed to the shared mass storage device via electronic download in multi-level encrypted form. Before being transported, the content is encrypted and then further encrypted. Once the content has been successfully transported, it is decrypted to remove the further encryption layer&#x2014;leaving the first encryption layer intact for protecting the video game during storage on mass storage at the remote distribution location.

Multiplexed secure video game play distribution

A car area network is disposed in a car to enable communications between various devices in the car. An existing consumer electronics device (CED) coupled to the car area network (CAN) performs an existing consumer electronics device function. That existing (CED) is adapted to control various devices coupled to the CAN including video gaming devices. In one example, the adapted CED cooperates with a game server to effect game play. In another example, the adapted CED functions as a virtual video game platform to support play of video games. A multifunction controller transmits control information to the adapted CED via the car area network to permit a car occupant to control the adapted CED to permit the occupant to play a video game using the video game display. One or more audio and/or visual devices coupled to the CAN may also be controlled by commands transmitted from the adapted CED or from the multimedia controller over the CAN.

Car-based entertainment system with video gaming

A handheld wireless device is adapted to function as a lightweight, small, and low-cost wireless server for serving handheld wireless clients. The handheld wireless server includes a battery that powers the server, data processing circuitry, read/write memory, and a memory port for receiving an external, detachable, long term, read/write storage device. The read/write storage device stores multiple dynamic server applications for execution by the data processing circuitry and multiple dynamic client applications for download to handheld wireless client devices. Wireless communications circuitry broadcasts initial information and detects communications from handheld wireless client devices including requests to download one of the client applications stored on the long term storage device. The data processing circuitry processes, in parallel, multiple download requests for client applications from multiple handheld client devices, retrieves the client applications from the long term storage device, and provides the client applications wirelessly to the multiple handheld client devices. An example application for traveler in a travel environment is described.

A system of electrical modules includes a plurality of modules, including power modules, control modules, and output modules. Power modules provide power for powering one or more control and output modules. Control modules provide control signals to one or more output modules. Output modules perform predefined functions responsive to receiving power from a power module and/or a control signal from a control module. All of the modules have like mating connectors and like connector wiring. This arrangement forms a system bus across any given plurality of modules, when those modules are serially interconnected in a daisy chain. In at least one embodiment, the mating connectors and the connector wiring are standardized across the system such that any module can be coupled to any other module, and the ordering of the modules in the daisy chain is not fixed.

Method and apparatus for implementing a consumer-configurable modular electrical system

A HVAC controls system for zone controls that is comprised of one or more Wall Sensor Units (WSU) and zero or more Damper/Register Units (DRUs). The invention is a low networked cost solution for residential and light commercial that is easy to install in new and existing building. The WSUs detect, log and use occupancy data to predict where in a building HVAC conditioning is needed and to save energy where it is not needed. The DRU use shape memory alloy wires to control the opening and closing of a damper plate with very little power allowing batter operation.
