Abstract: A method and apparatus is provided for reducing electromagnetic radiation emissions. The method and apparatus of the present invention also reduce or prevent electromagnetic radiation generated by sources outside of a system assembly from interfering with and adversely affecting electrical circuits in the assembly. An electromagnetic compatibility (EMC) solution uses a lossy element, and/or an element comprised of a combination of lossy and conductive material.

Abstract: Method and system for enhancing the reliability of an available storage subsystem. Data storage units are equipped with a number of I/O controller-card adaptors that mate with complementary adaptors affixed to a number of redundant I/O controller cards. The data storage devices plug directly into I/O controller cards and receive all data, control signals, and power equally from the I/O controller cards, eliminating the need for a midplane circuit card.

Abstract: A cost effective and easily manufactured filler for a removable system component. A hard disk drive filler embodiment is disclosed having five exterior sides and internal baffles to simulate the airflow modifying characteristics of a hard disk drive. The hard disk drive filler is stackable, flame-resistant, and is manufactured by an injection-molding process.

Abstract: A circuit board including differential bus traces on or buried within both sides of the board, interconnecting electronic devices such as disk drives, processors, and connectors for external cables. Via fields, which mimic the size and configuration of the device and cable connector fields, are located between each connector on the board. The via fields link bus traces on or within one side of the board with respective bus traces on or within the other side of the board. The via fields may include subtle, unequal undulations in the trace patterns to provide equalization in the lengths of all trace pairs. The via fields and the connector fields both include repetitive conductor order reversals in the trace connections on opposing sides of the board, to reduce crosstalk between channels. The via fields may be oriented parallel with respect to collinearly arranged devices, or orthogonal with respect to devices or connectors which are parallel.

Abstract: An EMI device that provides a low impedance mechanism for conducting noise currents in all orientations back to the source of the noise currents in order to more effectively reduce EMI emissions is herein described. The EMI device is constructed from an elastomer core that is wrapped with a metallized electrically conductive material. The gasket is die cut and as such includes one or more open edges that are non-conductive. The non-conductive edges are stitched with a conductive material thereby enabling multiple conduction paths between any surface or edge of the gasket with a electrically conductive enclosure. In this manner, the gasket is able to provide a return path back to the source of the noise currents for all orientations of the noise currents and hence, more effectively reduce EMI emissions.

Abstract: A data storage module alignment system and method for use in a data storage module and enclosure system including a module enclosure having a plurality of bay slots and at least one data storage module. The data storage module alignment system comprises at least one alignment guide that is adapted to be mounted at the module enclosure entrance and at least one guide rail that is adapted to be mounted to the data storage module. The alignment guide includes a plurality of guide channels having rounded edges. The guide rail is sized and shaped for receipt within the guide channels. Typically, the alignment guide further includes a plurality of guide flanges that are arranged asymmetrically along the alignment guide. The inner side of each guide flange defines an edge of one of the guide channels and includes chamfers which facilitate initial alignment of the data storage module within one of the bay slots of the module enclosure.

Abstract: A method and apparatus is provided for reducing or eliminating the amount of electromagnetic radiation being emitted from a system assembly comprising one or more subassemblies which comprise electrical circuits which generate electromagnetic radiation. The method and apparatus of the present invention also reduce or prevent electromagnetic radiation generated by sources outside of the system assembly from interfering with and adversely affecting the electrical circuits comprised in the subassemblies. To achieve these goals, the present invention provides an electromagnetic compatibility (EMC) solution which comprises a plurality of lossy elements, and/or elements comprised of a combination of lossy and conductive material, to reduce electromagnetic radiation.

Abstract: A new and improved aligning rod connector provides for securement in and to end alignment of rod sections (i.e., to fishing rod sections) by employment of a D-shaped shaft member affixed to one rod section and inserted into a chamber member with D-shaped bore, the latter member either an outwardly conforming with shaft D-shape or an outward symmetrical with rod shape, affixed to a second rod section end. The bore's three-fourths arcuate wall and one-fourth flattened surface of either outwardly differently configured chamber member is longitudinally coextensive from entrance to bottom thereof, and the three-fourths arcuate wall and flattened one-fourth surface of the shaft member is longitudinally coextensive from end to end, each member dimentioned to provide optimum frictional engagement in the radially outward pressing of said shaft against chamber bore, creating high intensity of frictional grip and suction, thereby precluding movement and dislodgment.
