Electrical bonding is the practice of intentionally electrically connecting all exposed metal items not designed to carry electricity in a room or building as protection from electric shock. If a failure of electrical insulation occurs, all bonded metal objects in the room will have substantially the same electrical potential, so that an occupant of the room cannot touch two objects with significantly different potentials. Even if the connection to a distant earth ground is lost, the occupant will be protected from dangerous potential differences.
Broadband coupler technique for electrical connection to power lines
ActiveUS7145440B2Creating unreasonable safety riskEliminate needCoupling device connectionsElectric signal transmission systemsElectric power transmissionTransceiver
Disclosed is a power line broadband communication system having broadband coupler devices capable of direct electrical connection to an energized power line. The coupler includes a conductive portion movable by an adjustable member from a non-conducting retracted position spaced apart from the power transmission line to a forward conducting position in electrical contact with the power line. An insulated arm supports the coupler on the power line. A base on the coupler is engageable with a remotely activated tool in order to accomplish the electrical connection in a safe and secure manner. Broadband data signals are sent to and from customer premises along the shared energized power lines. New coupler connections to the energized power lines allow the additional broadband customers and / or repeaters to join the communication system. Also couplers may provide connections to control electronics, routers, wireless transceivers, and may allow the broadband signals to bypass transformers on the power lines. The invention helps to minimize risk by allowing an installer to be remotely spaced from the energized power line while making the electrical coupling contact with the energized power line.

Thermoelectric devices having enhanced thermal characteristics are fabricated using multilayer ceramic (MLC) technology methods. Aluminum nitride faceplates with embedded electrical connections provide the electrical series configuration for alternating dissimilar semiconducting materials. Embedded electrical connections are formed by vias and lines in the faceplate. Methods are employed for forming tunnels through lamination and etching. A portion of the dissimilar materials are then melted within the tunnels to form a bond. Thermal conductivity of the faceplate is enhanced by adding electrically isolated vias to one surface, filled with high thermal conductivity metal paste. A low thermal conductivity material is also introduced between the two high thermal conductivity material faceplates. Alternating semiconducting materials are introduced within the varying thermal conductivity layers by punching vias within greensheets of predetermined thermal conductivity and filling with n-type and p-type paste. Alternating semiconducting materials may also be patterned in linear or radial fanout patterns through screening techniques and lamination of wire structures. A liquid channel within the faceplate is used to enhance thermal energy transfer. Thermoelectric devices are physically incorporated within the IC package using MLC technology.

A directional sensor array system generally for remote audio collection applications that is modular, scalable, and robust with the modules assembled in layers. The invention can alternatively employ sensors other than microphones, such as ultrasonic transducers and accelerometers. In the preferred embodiment, the sensors are mounted on tiles, each of which performs its own local beamforming using a low-impedance resistive summation technique.

Multiple tiles can be joined together physically and electrically. When joined, a secondary parallel beamforming is performed on the bus using electrical summation. Due to the techniques employed, large scale arrays are feasible at low power consumption—for example, an array of 400 microphone elements can be powered for over 6 hours by a single 9 volt battery.
