Abstract:
The invention is directed to a method of bonding a hermetically sealed electronics package to an electrode or a flexible circuit and the resulting electronics package that is suitable for implantation in living tissue, such as for a retinal or cortical electrode array to enable restoration of sight to certain non-sighted individuals. The hermetically sealed electronics package is directly bonded to the flex circuit or electrode by electroplating a biocompatible material, such as platinum or gold, effectively forming a plated rivet-shaped connection, which bonds the flex circuit to the electronics package. The resulting electronic device is biocompatible and is suitable for long-term implantation in living tissue.
Abstract:
A system for communicating between multiple electrical components includes a first printed circuit board (PCB) having first and second opposed layers and a plurality of plated through-holes extending between the first and second opposed layers. The system also includes a plurality of mating contacts, wherein each of the plurality of mating contacts is retained within one of the plurality of plated through-holes. Each of the plurality of mating contacts may include a first end portion that outwardly extends from the first layer, and a second end portion that outwardly extends from the second layer. The system may also include a first connector assembly having a plurality of interconnecting contacts retained therein. The plurality of interconnecting contacts mate with the first end portions of the plurality of mating contacts when the first connector assembly connects to the first PCB.
Abstract:
A control unit, e.g., for a motor vehicle, includes a circuit board, a high-impedance circuit component situated on the circuit board and having an impedance of 1 kΩ or higher in relation to ground of the control unit, and at least one conductive protection element electrically connected to ground and situated adjacent to the high-impedance circuit component. The protection element has a height within a protective distance from the high-impedance circuit component that is at least equal to the protective distance. A method for designing a circuit board of a control unit, and a computer program product for executing the method, include the steps of specifying a position of the high-impedance circuit component, and specifying a position of the protection element such that the protection element has a height within a protective distance from the high-impedance circuit component that is at least equal to the protective distance.
Abstract:
A gas turbine engine 10 is provided with electrical harness rafts 200 comprising electrical conductors embedded in a rigid composite material. The rafts 200 are used to transport electrical signals (which may be, for example power and/or control signals) around a gas turbine engine. Rafts 200 may be connected together and to other components using flexible cables, that may help to accommodate relative movement of the rafts 200, for example through vibration. The rafts 200 are lighter, more compact, and more convenient to handle than conventional electrical harnesses. The rafts 200 may provide a convenient and secure mounting surface for other components/systems of a gas turbine engine, such as EECs and/or fluid pipes.

Abstract:
In at least one embodiment, a vehicle power module comprises a first printed circuit board (PCB) including a first plurality of electrical components for providing a first voltage and a second voltage. The vehicle power module further comprises a second PCB including a second plurality of electrical components, the second PCB being spaced away from the first printed circuit board and a first connector assembly being coupled to the first PCB and to the second PCB for providing the first voltage to the second PCB. The vehicle power module further comprises a second connector assembly being coupled to the first PCB and to the second PCB for providing the second voltage to the second PCB. The first connector assembly provides the first voltage of up to 14V and the second connector assembly provides the second voltage of 200V or greater.
Abstract:
A bussed electrical center has a power cable for feeding electrical power to the bussed electrical center. A printed circuit board subassembly is interposed between a first housing member and a second housing member that are connectable together. An electrically conductive connector has a prong end and a distal end. The prong end is operably connected to the printed circuit board subassembly. A first fastener and a second fastener are positioned on opposite sides of the first and second housing members. When the first and second fasteners are tightened together to a draw the first and second housing members together to mechanically fasten the bussed electrical center together, the distal end and the terminal end are pressed against each other for electrical connection to each other to electrically connect the power cable to the printed circuit board subassembly.

Abstract:
A connecting member such as a terminal base is used, which allows a printed circuit board unit in which circuit elements such as a power module are mounted on a printed circuit board to be rated at higher current as compared to a conventional printed circuit board unit; and therefore an increase in size of the unit can be reduced or prevented with a simple configuration of connection sections. The connecting member of an electrical circuit connects the circuit element of the electrical circuit including the printed circuit board, to an electrical wire. The connecting member includes a terminal connecting section to be directly connected to terminal pins of the circuit element; a wire connecting section to be connected to the electrical wire; and attachment sections for attaching the connecting member to the printed circuit board.
