Abstract: Techniques for the construction and use of cable protectors are described herein. The cable protectors may be used to protect cables in a wide variety of applications, locations and environments, including a utility (e.g., water or gas) metering application. In one example, the cable protector may protect a cable connecting a water meter to a radio. The cable protector may be constructed of a ribbon of durable material (e.g., stainless steel) configured as a helix. The helix may define a central channel through which the cable may pass. The cable protector may have spacing between adjacent turns of the helix that are too narrow to allow attack of the cable by animals. Exact dimensions may depend largely on a size of a cable to protect, and an environment and use of the cable.

Abstract: A method and structures are provided for implementing customizable dielectric printed circuit card traces. A void is defined near selected signal traces. The void is then filled with a dielectric material having a predefined dielectric property. The dielectric material is selected to alter at least one predefined electrical property of the selected signal traces, such as, coupling, propagation delay and attenuation. In one embodiment, an outer layer of a printed circuit card includes a plurality of signal traces and a mating circuit card layer including a plurality of matching signal traces is attached to the outer layer of the printed circuit card to create a cavity near selected signal traces. The cavity is filled with the selected dielectric material. In another embodiment, dielectric material is selectively removed near signal traces on an outer layer of the printed circuit card to define a void near selected signal traces.

Abstract: A method, apparatus and computer program product are provided for implementing automated detection of excess aggressor shape capacitance coupling in printed circuit board layouts. A PCB design file containing an electronic representation of a printed circuit board design is received. A list of candidate shapes is identified. The candidate shapes are disposed on layers adjacent to aggressor planes. A capacitance coupling the candidate shapes to adjacent aggressor planes is calculated. A ratio of the calculated capacitance and a decoupling capacitance connecting the candidate shapes to a reference plane is determined.
