A modular illumination system includes light emitting tile modules, each module comprising a light guide substrate, at least one source of illumination optically coupled to a light guiding substrate and interconnection means to connect one light emitting tile module to another light emitting tile module. The interconnection means may include mechanical and/or electrical elements. A plurality of modules may be connected to create an extended continuous extended illuminating system without significant gaps or seams. In one embodiment, the light guiding substrate of one module extends over the source of illumination of an adjacent module. In a further embodiment, the light guiding substrate may be textured to create a patterned area with higher light extraction. In a further embodiment, the source of illumination may be included in a separate electrical member. The illumination sources may include LEDs directed into an edge of the light guiding substrate.

A pair of glasses with one or more electrical components partially or fully embedded in the glasses is disclosed. In one embodiment, a pair of glasses includes a speaker and an electrical connector, both at least partially embedded in the glasses, with the speaker and the connector electrically coupled together by an electrical conductor.

A multiuse electric tile module for walling, flooring, or roofing applications having a photovoltaic cell, thermovoltaic cell, electroluminescent material, or a combination of these disposed over a rigid substrate, such as ceramic. Each tile is electrically connectable through a male-to-female connecter to at least one adjacent tile without external wiring. Preferably, a sealing layer is disposed over the electrical elements and rigid substrate to seal and protect each tile. Optionally, each tile may further include an inverter to convert direct current to alternating current or a battery to store electricity. The electroluminescent material provides light for architectural accents or nighttime visibility.

An electrically conductive element for protecting electrical components positioned within a cable connector or cable terminator from high voltage surges includes a ring that is positioned in circumferentially surrounding relation to the input pin of the connector or terminator that carries the signal being transmitted by the coaxial cable. The ring includes at least one prong that extends radially inward therefrom which terminates in close but non-contacting relation to the input pin. When a high voltage surge of electricity is carried by the coaxial cable transmission line, a spark is formed in the gap between the prong and the cable connector or terminator. As a consequence, the high voltage surge is transferred to the surge protection element which in turn conducts the electricity to the grounded body of the connector or terminator.

At least two electric elements (203) such as semiconductor chips or surface acoustic wave devices are mounted on wiring patterns (201), and the electric elements (203) are sealed with a thermosetting resin composition (204). An upper surface of the at least two electric elements (203) and an upper surface of the thermosetting resin composition (204) are abraded at the same time, thereby forming surfaces substantially flush with each other. Since they are abraded while being sealed with the thermosetting resin composition (204), it is possible to reduce the thickness without damaging the electric elements (203). Also, the electric elements (203) and the wiring patterns (201) can be prevented from being contaminated by an abrasive liquid. In this manner, it is possible to obtain an electric element built-in module whose thickness can be reduced while maintaining its mechanical strength.

A rechargeable battery system and method are disclosed, in which an implantable medical device (IMD) regulates its transfer of energy from a separate charger unit. For recharging, a charger unit is brought into proximity to the implanted device. An oscillating current is generated in a primary coil, located in the charger. By inductive coupling through an oscillating magnetic field, an alternating current is generated in a secondary coil, which is implanted in or near the implanted device. The alternating current then passes through a half-wave or full-wave rectifier to form a one-sided current, then passes through a regulator to form an essentially direct current, which is in turn directed to the rechargeable battery in the implanted device. The secondary coil has a controllable damped resonant frequency, which can be dynamically tuned away from the driving frequency of the primary coil by a variable resistor and/or by varying a duty cycle of a rapidly switched electrical element. If a control loop in the implant senses that more power is being received at the second coil than is actually being used to recharge the battery, the control loop temporarily changes the variable resistance. When this happens, the resonant frequency of the secondary coil is detuned slightly away from the driving frequency, so that less of the incoming power is absorbed by the secondary coil. Alternatively, the secondary coil may be temporarily short-circuited. With less or no excess power entering the circuitry of the implant, the problem of overheating is mitigated.

An electrical device is provided, including a substrate, an electrical component on the substrate, and a battery on or integrating the substrate for providing electrical energy to said electrical component. An open switch prevents electrical communication between the electrical component and the battery while open. A circuit activating component is adapted to irreversibly close the open switch to thereby establish a permanent electrical circuit between the electrical component and the battery.
