Abstract:
A surgical instrument (100) is disclosed having an elongated body portion (126) having a proximal end and a distal end. The body portion is formed from a plastically deformable material such that the body portion can be bent between the proximal and distal ends from a first configuration to a second bent configuration and maintains the bent configuration. A flexible circuit sheet (232) having at least a pair of lead wires (236) disposed around the body portion. The pair of lead wires are configured to conform to the bent configuration of the body portion such that they do not break during bending of the body portion. A tracking device (84) adapted to cooperate with a navigation system (10) to track the distal end of the instrument (100) is coupled to the flexible circuit.
Abstract:
There is provided a printed circuit substrate and a noise suppression structure capable of minimizing constraint on a component layout on a substrate and suppressing noise. The printed circuit substrate (110) includes conductive patterns (111, 113, 115) of odd numbered layers and conductive patterns (112, 114, 116) of even numbered layers which are alternately arranged in a vertical direction and hold an insulating layer between each layer. Portions excepting predetermined areas for connecting a first through-hole (117) and predetermined areas for insulating from a second through-hole (118) in the conductive patterns (111, 113, 115) of the odd numbered layers have a same shape as portions excepting predetermined areas for connecting the second through-hole (118) and predetermined areas for insulating the first through-hole (117) in the conductive patterns (112, 114, 116) of the even numbered layers, and the portions are laminated on one another at the same position in the vertical direction.
Abstract:
Provided is a wiring substrate which allows connection terminals to be disposed at high density, can increase the degree of freedom of wiring layout, and can enhance the reliability of connection of the connection terminals. A wiring substrate of the present invention includes a laminate which includes one or more insulating layers and one or more conductor layers laminated together; a wiring formed on the laminate; a columnar connection terminal which is formed directly on the wiring and is in contact with at least one of opposite side surfaces of the wiring; and a solder resist layer which covers the wiring and which exposes at least a portion of the connection terminal. The width of the wiring at a position at which the connection terminal is formed is smaller than the length of the connection terminal in the width direction.

A printed solenoid inductor delay line system comprises discrete delay sections, where the inductor is implemented in the form of a printed, spiraling solenoid, with the solenoid axis in the plane of the multi-layer printed circuit board (PCB).
Abstract:
A laminated electronic component including at least one inductance element and produced froma laminate having electrical insulators and electrical conductors laminated alternately. The inductance element is formed as a helical coil having a plurality of turns each constituted by four sides. The inductance element has pairs of parallel conductor pieces and pairs of bridging conductor pieces. Each pair of parallel conductor pieces form two of the four sides of one turn of the coil. Each pair of bridging conductor pieces form the other two sides of one turn of the coil. Grooves are formed in the laminate to thereby form the parallel conductor pieces. The grooves are filled with an electrically insulating material. The bridging conductor pieces are formed on the electrically insulating material.
Abstract:
The present invention relates to the methods of construction for inductive components of, preferably, ferromagnetic materials such as inductors, chokes, and transformers when used as an integral part of the fabrication of PCB's or FLEX's. In one preferred embodiment, holes (56, 58) are formed through a ferromagnetic substrate (50) and plated with conductive material. The arrangement of these holes, and the subsequent design that ensues, will form the inductive components within the plane of the media in which the device is formed; using the substrate (50) for a magnetic core (90). By using this approach, the inductive components can be miniaturized to physical sizes compatible with the requirements of modern surface mount technology (SMT) for integrated circuitry (IC). This process also allows these components to be fabricated using mass production techniques, thereby avoiding the need to handle discrete devices during the manufacturing process. In another preferred embodiment, a series of thin, concentric high permeability rings (315) are etched on a substrate (330) to provide high permeability transformers and inductors having minimal eddy current effects.
