Abstract: A portable ionizer is arranged for generating ionized air in an area of a user's fingers. The portable ionizer includes a battery-powered oscillator coupled via a high voltage conversion circuit to a positive electrode and a negative electrode for generating positive and negative ions. A fan positioned near the positive and negative electrodes is arranged providing a positive and negative ion flow path to the area of the user's fingers.

Abstract: The transferrable EMI gasket assembly utilizes a carrier with a pair of arms, each attached to a back panel by a hinged connection and extending in the same direction to overlie one another. The conductive, deformable gasket material is attached to the carrier and positioned adjacent the back panel. The assembly is collapsed for installation with the back panel overlying one of the arms hinged thereto to present a reduced height. The assembly is placed in the operative position by moving one arm relative to the other to pivot the carrier back panel to a near right angle position with respect to the carrier arms. In the operative position, the gasket material is compressed and deformed against the confronting surfaces to effect the EMI seal while the biasing force of the compressed gasket material, in the preferred embodiment, secures the carrier arms together.

Abstract: A fan and a fan blade are provided for allowing airflow through the fan blade in a fan failure condition. The fan blade includes a peripheral member defining an opening. A flexible cover member is attached to the peripheral member for covering the fan blade opening during normal operation of the fan. The flexible cover member is hingeably attached to the peripheral member for movement away from the peripheral member enabling airflow through the fan blade opening in a fan failure condition.

Abstract: Methods and apparatus are disclosed for a tunable inductor. A coil of electrically conducting material is wrapped around a coilform, preferably generally cylindrical in shape. The coilform is constructed having a threaded portion of screw-like ridges with troughs between the ridges. The coilform may also have an unthreaded portion. The ridges and troughs of the threaded portion may run along substantially all of the coilform or just a portion of the coilform. As the coilform is rotated, the electrical conductor is engaged in the threads, changing the shape of the coil, and thereby also changing the inductance of the coil.

Abstract: A device for piercing a cable includes a first clamp member and a second clamp member. The first clamp member and the second clamp member are superposed relative to each other. A conductive piercing member is disposed on the first clamp member. The device further includes an arrangement for moving the first clamp member and the second clamp member together. As the first clamp member and the second clamp member are moved together, a distance between the conductive piercing member and the second clamp member is reduced.

Abstract: Concurrent maintenance of an electronic system, such as a computer system, is performed in the presence of potentially disruptive Electromagnetic Interference (EMI) by shrouding components within the computer system with a grounded, electromagnetic shielding sheet. In particular, Radiated Electromagnetic Susceptibility (RES) of the computer system is protected when an opening formed in an enclosure of the computer system is shrouded by the electromagnetic sheet. Slits or openings are formed in the sheet to allow access to the components within the shielded system. The sheet is formed of a static shielding polymer with a thin metal layer, and is grounded with an attached grounding member.
