A jumper cable module for use, e.g., with optical and/or electrical equipment. The module provides proper tensioning for jumper cables and retains them in a protected manner. In one embodiment, the module includes a pulley and an eccentric cam pivotally connected to a base plate. A jumper cable is wrapped around grooves in the pulley and cam such that the connectorized ends of the cable extend out and attach to the specified connection points. The cam is turned about its axle to produce the desired tension of the cable. For maintaining the tension, the cam may incorporate a tensioning mechanism, e.g., a spring-loaded ball mechanism or serrated edge ratchet. When the cable needs to be removed from the module, the tensioning mechanism is disengaged and the cam is turned to create slack in the cable for ease of cable removal. A module that includes stacks of pulleys and cams may handle multiple jumper cables. Certain modules of the present invention reduce damage to and improve handling of fiber optic jumper cables during installation and maintenance of optical communication equipment.

An economical protective shield assembly of a dielectric substrate and an EMI shield, substantially free of the effects of board coupling and air coupling which requires less hardware for securing an EMI shield than present devices and methods, is provided for. The inventions use of simply finished shield edges with an unimproved substrate having a conductive intermediary interconnected with a grounding path and simply finished or unfinished shield edges with an improved substrate having a mating groove cooperatively adapted to fit the shield edge, interacts to exclude EMI signals and requires less precision in positioning the shield onto the substrate. The invention also provides a simplified method to exclude EMI effects for an assembly by a process of fabrication requiring less finishing steps than present processes.

A protective enclosure for housing heat-generating electronics, having a sorption device for controlling humidity and a heater for heating the sorption device. The invention protects electronics placed within the enclosure from the effects of water vapor and condensation during normal operation and in the event of power loss. The sorption device adsorbs water vapor during normal operation or power loss when the temperature in the enclosure falls below the dew point. The sorption device releases collected water as water vapor when power is restored and the temperature in the enclosure rises above the dew point. The invention thereby prevents failure of the electronics due to condensation build-up and provides for effective long-term use of the sorption device.

A unitary display and sensing device integrates liquid crystal display module elements of a liquid crystal display module for detecting input on a flat panel display screen with the capability for digitizing the detected inputs. In accordance with an illustrative embodiment of the present invention, display elements of a liquid crystal display module are modified to sense input on the display screen. An electrical signal is applied to modified display elements of the liquid crystal display module so that contact with a surface portion of the display screen produces an output signal indicative of its location. The integrated display and sensing device is active matrix addressed for finger input, but may also incorporate display systems for active pen input.
