Abstract: A mechanism for protecting objects sensitive to electrostatic discharge (ESD) employs nested plates to direct the flow of ESD current to a targeted impedance. In one embodiment, an insulator plate is interposed between first and second electrically conductive plates. The insulator plate prevents any charge accumulating on the first plate from arcing to the second plate through the insulator plate. A target plate of electrically conductive material is interposed between the first and second plates over a hole in the insulator plate. The target plate, which is surrounded by an impedance layer of static dissipative material, includes a discharge portion that projects toward the second plate. ESD current flows in a path from the first plate, through the impedance layer, the target plate and again through the impedance layer, and to the second plate. The impedance layer provides a targeted impedance in the ESD current path.

Abstract: A method and circuit for implementing a coded time domain transmission distance meter, and a design structure on which the subject circuit resides are provided. A first transmitter module connected to a cable at a first point or power outlet, generates and sends a testing coded pulse onto the power cable.

Encoded in the testing coded pulse are data representing the last calculated distance. Both the first transmitter module and the second receiver module include a display for displaying the calculated distance.

Abstract: A method and system for controlling the electrical connection between the metallic covers and the underlying metal chassis of an electrical system by the select placement of impedances in a current control connector. The current control connector places an impedance, capable of controlling electrostatic discharge (ESD) currents, between the covers and the underlying chassis. The current control connector comprises a number of metallic and dielectric components. Each of these components is ideally chosen such that the structure and composition of each component contributes to an overall functionality of the current control connector and an ability to control the ESD current flow. The relative placement of the components of the current control connector allows the current control connector to eliminate current flow along a number of paths but control the current flow along a preferred path. Thus, the current control connector prevents damage to the internal electrical system.
