Abstract: An adapter module used to convert optical signals to electrical signals or electrical signals to optical signals utilizing a “C” shaped retaining clip to secure the adapter module housing together. The retaining clips are used in place of screws, rivets or snap fits and provide an easy and simple way to assembled adapter modules. The retaining clips require no additional structure thereby minimizing the overall size of the adapter module.

Abstract: According to various aspects, exemplary embodiments are provided of gaskets that can protect fingerprint readers from receiving electrostatic discharge surges when a user's finger is placed in contact with the electronic scanning portion of the fingerprint reader. In exemplary embodiments, a gasket can provide an electrically-insulative barrier between the exposed contact points on the sides of the fingerprint reader, the electrostatic discharge, and the electrically-conductive side of the gasket. The gasket can also include an electrically-conductive side that provides a relatively short path to ground for the electrostratic discharge.

Abstract: An electromagnetic interference (EMI) gasket for an electronic module comprises a valley feature formed on one side of an EMI gasket and a crown feature formed on the other side of the EMI gasket in order to complement the valley. One or more EMI gaskets are used to construct a shield across the opening of a module cage or rack. Each gasket forms a link in a series of modules, in order to complete a seal across the opening in the cage. A perpendicular pressure forces the module gaskets to center and align evenly as the crown and valley of the opposite features nest together. The modules can be then pressed together and the overlap of the crown and valley acts to center the alignment and create a pressure for satisfactory EMI grounding and the reduction of EMI leakage.

Abstract: According to various aspects, exemplary embodiments are provided of flexible clip-on shielding and/or grounding strips capable of being clipped onto and disposed along a curved edge portion of a mounting surface. In one exemplary embodiment, a flexible clip-on shielding includes an array of generally transversely extending slots. At least some of the slots have a closed end portion and an open end portion such that the closed end portions are at alternating ends of the slots and such that the open end portions are at alternating ends of the slots. Finger elements are defined by the slots. At least one finger element is defined generally between a first pair of slots with at least one slot between the first pair of slots. At least one other finger element is defined generally between a second pair of slots without another slot between the second pair of slots.

Abstract: The present invention insulates the source of noise efficiently by forming a thick noise insulating portion to the cover to tightly seal a drive unit which generates heat and noise and at the same time, increases the cooling effect of cooling fins by making the surface areas of the cooling fin ends that are away from the noise insulating portion wide by the amount equivalent to the surface area of the cooling fins decreased by the noise insulating portion provided, and obtains the shielding cover that is excellent in both cooling and noise insulation.

Abstract: The invention relates to an EMI gasket formed by joining coated steel (3) and a contact backing (1). The coated steel (3) has elongated openings (4), into which projections (2) provided on the contact backing fit, seizing by their edges the edges of the openings.

Abstract: A vent grid has parallel first electrically-conductive members and parallel second electrically-conductive members intersecting with the first electrically-conductive members. The intersection between the first and second electrically-conductive members is forced to have a larger cross-sectional area. The characteristic impedance thus increases. The electric current flowing through the first and second electrically-conductive members turns over at the boundary between the intersection and the first and second electrically-conductive members. The flow of the electric current is in this manner interrupted. Accordingly, the vent grid fails to induce electromagnetic wave. Moreover, the electrically-conductive piece is merely located at a corner of the opening. Decrease in the percentage of the opening is thus suppressed to the utmost per a unit area. A sufficient airflow can be established through the vent grid. Decrease in the cooling efficiency and performance can be suppressed.

Abstract: A method for mounting a fingerstock EMI shielding gasket on a sheet metal structure includes the steps of forming tabs which protrude from the surface of the sheet metal structure. The shielding gasket, which has a generally D-shaped cross section with at least one mounting tab forming at least part of an upright portion therefor, is inserted into position longitudinally between the tabs.
