A resilient, electrically conductive EMI gasket is disposed between two jaws. A cam-lever or other actuator is operably linked to the jaws. The cam-lever can be used to drive the jaws closer together, thereby squeezing the gasket and causing a portion of the gasket to protrude, preferably beyond an edge of at least one of the jaws. The protruding portion of the gasket contacts a mating surface of an opening, through which a device was installed, or a mating surface on an adjacent device. This contact seals the space between the EMI gasket mechanism and the mating surfaces, i.e. the contact closes a gap and thus maintains a continuous EMI shield therebetween. The gap is closed against passage of EMI radiation without relying on device insertion force to cause the EMI gasket to adequately contact the mating surface. Alternatively, an inflatable resilient EMI gasket is in fluid communication with a pump, and an actuator is operably linked to the pump. The actuator can be used to operate the pump and, thereby, inflate the gasket, thus causing a portion of the gasket to protrude and contact a mating surface.

Expandable electromagnetic interference (EMI) gasket mechanism

An electromagnetic shield assembly is disclosed. In one embodiment, the present invention is comprised of a frame. The present embodiment is further comprised of an electromagnetic gasket surrounding the frame. The present embodiment is also comprised of an actuating element coupled with the electromagnetic gasket. The actuating element is adapted to retract and deploy a portion of the electromagnetic gasket with respect to the frame to provide an adjustable electromagnetic interference (EMI) shield.

Electromagnetic shield assembly

An EMI reduction system comprises a conductor and a lossy coating encasing the conductor and comprising one or more lossy layers. The one or more lossy layers further comprise a binder and a lossy material mixed into the binder. The lossy material is selected to attenuate electromagnetic interference frequencies in a narrow or moderate band.

Lossy coating for reducing electromagnetic emissions

A system method for determining temperature anomalies that would affect the proper operation of a computer and, upon receipt of a determined temperature anomaly, causing certain data to be saved within a storage device in a file location appropriate for such data.

System and method for protection of active files during extreme conditions

A system and method for determining motion anomalies that would affect the proper operation of a computer and, upon receipt of a determined high motion anomaly, causing certain data to be saved within a storage device in a file location appropriate for such data.

System and method for protection of equipment during motion anomalies

A conductive clip is placed over a component mounted to a printed circuit board (PCB) to form a conductive path between terminals of the component. In one embodiment, a conductive clip is placed over a surface mount technology (SMT) component, with the clip having ends that include a flared portion and a sharp triangular retainment detent. In another embodiment, the clip has a shoe box shape and includes two sides having retainment detents that are disposed to engage an area between an edge of the component and the PCB. In yet another embodiment, the present invention is adapted for use with through hole mounted components having axial leads, with each end of the clip including a slot that engages a lead when the clip is pressed onto the component. The present invention allows a PCB to be designed to support multiple configurations without using DIP switches or headers/jumpers.
