Abstract:
A shield can (1) for shielding electronic components on a PWB (printed wired board) (6) in an electronic device. In order to compensate for any non-planarity of the PWB, the shield can (1) is divided into sections (2) that are linked together in a flexible manner.
Abstract:
An apparatus and method for forming a conical or domed ring light (20) having a plurality of light sources (36) arranged at a desired angle with respect to the optical axis. The light sources are installed at desired locations on a first surface of the flexible circuit board (22) and are each coupled to a common electrical connector (37), having one or a plurality of power sources, to facilitate supplying electrical power to each one of the light sources. The circuit board is then folded into a conical or domed configuration (39), with the light sources facing inward, and each abutted end and lateral surfaces of the folded circuit board is suitably secured or fastened to one another to permanently retain the flexible circuit board in its folded state.
Abstract:
A novel technique utilizing the precision of printed circuit board design and the physical versatility of thin, fexible substrates is disclosed to produce a new type of ion reflector. A precisely defined series of thin conductive strips (traces) are etched onto a flat, flexible circuit board substrate. Preferably, the thin conductive strips are further apart at one end of the substrate and get increasingly closer towards the other end of the substrate. The flexible substrate is then rolled into a tube to form the reflector body, with the conductive strips forming the rings of the ion reflector. The spacing between the traces, and hence the ring spacing, can be readily varied by adjusting the conductor pattern on the substrate sheet during the etching process. By adjusting the spacing between the rings, the characteristics of the field created by the reflectron can be easily customized to the needs of the user.
Abstract:
A method and apparatus is provided for applying a fluid to a plurality of locations on a non-planar substrate (26) . The apparatus includes a movable base (28) and an array of pins (30) connected to the base (24). Each pin (30) has a distal end (32) which is vertically movable with respect to the base (24) independently of the rest of the array of pins. Each distal end (32) is adapted to transfer fluid to a location on the substrate (26) by having a greater affinity for the fluid than the fluid has for itself and a lesser affinity for the fluid than the fluid has for the substrate. Accordingly, the distal ends (32) may be dipped in the fluid and moved into contact with the substrate (26) such that the distal ends may collapse toward the base (28) as the distal ends (32) engage the substrate (26) to facilitate further movement of the base toward the substrate for application of fluid to each of the plurality of locations.

The invention relates to an electrically conductive unit (1) extending by means of electrically conductive paths (10, 29), which are directly or indirectly applied onto a case (2), for creating a screening against electromagnetic radiation and/or for the draining of electrical currents.
