Abstract: A system and method for supplying back-up electric power to a house or other building from a hybrid vehicle. Switches in the vehicle and in the house can place the vehicle in a mode where it receives charging power from the house, or where it can supply power into the main electrical distribution system of the house. These switches can be controlled from a control module in the house that can sense or cause the vehicle to sense if there is adequate ventilation in the environment to start the internal combustion engine (ICE) in the vehicle. The control module or the vehicle can cause a garage door to open or ventilation fans or vents to open. If the ICE can be started, the generator/battery can supply most if not all of the power needed by the house until the outage is over. If there is inadequate ventilation, the control system can cause only the battery in the vehicle to supply limited power to the house, typically only to critical circuits.

Abstract: An electronic device, like a mobile telephone, has a first section and a second section. The first section and second section are coupled together by a mechanical connection, for example a hinge, swivel or sliding connector. Electronic components in the first section are coupled to electronic components in the second section by conductors capable of transferring power between the first and second sections. A current detector is capable of detecting currents, like surface currents, while a controller is responsive to the current detector. A plurality of reactive elements, like capacitors for example, are coupled to a plurality of switches such that the controller may selectively couple any of the plurality of reactive elements to the conductors by actuating a corresponding switch.

Abstract: If the mobile station (101) locates a peer it will request network metadata and may obtain location related services or service lists. The mobile station (101) negotiates with one of more peers (103) to share the work load of background scanning for network services. After successful negotiation, any peers in the “discovery net” will report or advertise to each other of any newly discovered networks, or networks to which connectivity has been lost. Since the various mobile stations may, when powered on, scan periodically for network changes, the metadata stored on the mobile station (101) will be dynamic and will change periodically upon travels and/or encounters with additional peers. Because the peers (103) may also possess location information, the mobile station (101) may additionally adjust its scan to prioritize services advertised by those members of peers (103) that are located most proximate to the mobile station (101).

Abstract: A flexible test cable has a center conductor (210), a conductive sleeve (240) with an effective electrical length equal to an odd quarter wavelength of a frequency of interest, a dielectric spacer (230) located inside the conductive sleeve (240) for preventing a portion of the center conductor from electrically coupling to the conductive sleeve, and a dielectric joint (220) for maintaining a portion of the center conductor in the middle of an end of the conductive sleeve (240).
