Abstract: A printed circuit board for coupling surface mounted optoelectric semiconductor devices within a computer system is disclosed. The printed circuit board includes at least one substantially planar surface. There are multiple electrically conductive sites located on the substantially planar surface for connection to a surface mounted semiconductor electronic device. The electrically conductive sites are also connected to electrical interconnects embedded within the printed circuit board. In addition, there are multiple optical pathways terminated at the substantially planar surface. A droplet of viscous fluid is placed at each of the optical pathways terminated at the substantially planar surface in order to provide better coupling between a surface mounted semiconductor optoelectric device and the printed circuit board.

Abstract: The present invention relates to an electrically insulating polymer coating on a conductive metal substrate, especially zinc and tin-plated sheet steel. The polymer is applied to at least one side of the sheet, the amount being adequate to create a uniform layer of 0.5 to 0.8 micrometers thickness after curing. The polymer coated sheet is heat cured at 200° C. to 210° C. for 10-15 minutes. The thickness of the polymer layer is selected to be within a specified range. The range is determined based upon subsequent manufacturing operations which require an electrically conductive path between a component and the metal substrate. The curing conditions are selected for the dual purpose of heat curing the polymer to the substrate surface as well as to stress relieve the tin or zinc-plated sheet steel. This treatment helps to prevent tin whisker growth and improves the corrosion resistance of the substrate.

Abstract: A system for mounting components within a frame of a personal computer where access to only one side of the frame is needed to mount or remove the components with fasteners and fastening tools. The components are secured and restrained from movement in three orthogonal directions. The fasteners are mounted to the exposed side. Bracket guides and spring fingers extend from the frame to provide location and biasing forces to secure the components in their proper locations. This system requires fewer fasteners and reduces assembly time during manufacturing and/or repair. It is easier and quicker to remove and replace a defective component or one which is being upgraded in the system.

Abstract: A printed circuit board connector edge tab design has increased tab contact area with a large local capacitance at the connector interface. This serves to balance out the inductive effects of the connector and results in a lower overall channel impedance at the interface. The invention replaces the prior art plated pathway to the upper row of tabs with wider tabs on the lower row. The edges of the lower row tabs are spaced such that each of the connector pins destined for the upper row straddle two of the lower tabs as they travel upward. This design prevents the pins from contacting the fiberglass substrate of the board while it traverses the lower row of tabs. The absence of the prior art plated pathways allows each of the lower row tabs to be expanded into the space formerly occupied by the pathways. This design also allows the increased capacitive area of the edge tabs to be located in very close proximity to the connection area between the connector pins and the edge tabs.

Abstract: A system and method for monitoring tamper events in a computer system in accordance with the present invention is disclosed. The system comprises a detector means for detecting at least one tamper event and for providing an indication when the tamper event has occurred for longer than a predetermined time period. The system also includes an adapter means coupled to the detector means for receiving the indication and for disabling the computer system. The present invention is directed to a computer system, which has the ability to functionally determine if a tamper event is authorized and therefore allows the computer to operate after such an event. In a preferred embodiment, the tamper event could be as simple as a toggle switch being activated when the cover of the personal computer is removed.

Abstract: A system and method for recovering from corruption of an executable application and/or operating system stored on a client computer without downloading another copy of the application and/or operating system. This recovery is accomplished by storing, preferably at the initial program loading, two copies of the application (and the operating system, if desired) in different segments of a partitioned storage, one copy as a working copy and a second copy as an archive or backup copy. When the working copy of the application or operating system becomes corrupted and crashes, the backup copy is thereafter used as the new working copy and, if desired, a new backup copy is stored to be used when the working copy crashes. This allows the system to continue functioning after a crash without the necessity to find a new copy of the application and operating system from outside the computer.

Abstract: A compact media drive for use in personal computers has a media support and detector arm structure that ejects to extend external of the drive case at the insertion slot to receive corners of a unit of media during data operations. The arm(s) retract within the drive case or system case when no media is received. This allows a drive case to be proportioned with a drive hub for the media adjacent to the insertion slot to reduce the dimension there between from that for normal full disk insertion. The arm structure permits the drive to collect state information at the rear disk corners necessary to avoid incorrect data operations while a significant portion of the disk remains outside the insertion slot.

Abstract: A client on a network is provided with low power logic, at the network adaptor, that is always active and simulates network packet traffic (e.g. Ethernet packets) normally sent under control of the main client system processor(s). This logic collects client status information regarding power state and reports to the network manager such information which allows the network manager to exercise broader control and perform maintenance and upgrades which would usually require a dialog with the user and consequently limit off-hours reconfiguring of the client.

Abstract: A data processing system includes a bus, one or more loads coupled to the bus, and a clock generator. The clock generator generates a bus clock signal that is coupled to at least one of the loads. While the clock generator is generating a bus clock signal having a first frequency, the number of loads connected to the bus is determined. In response to this determination, the frequency of the bus clock signal is automatically changed from the first frequency to a second frequency. In one embodiment in which the bus is a PCI local bus having a plurality of slots, the determination of the number of loads is made by examining at least one storage location associated with each of a plurality of slots.

The RFID tag is mapped into the workstation computer memory space and can also be read and written by radio frequency signalling through a wired plug and access flap in a shipping carton. Serial numbers and MAC address is stored on the tag by the manufacturer. User information, workstation profile and software image information is stored onto the tag while the computer is being received for forwarding to the final workstation destination without the need to unpack and power up the computer. The information stored on the tag is used to allow automated system configuration and software downloading to the computer.

One aspect of the present invention further includes comparing the unique serial numbers with corresponding last known serial numbers, wherein a mismatch in the serial numbers indicates that the corresponding memory modules have been replaced.

Abstract: A method and apparatus for securing a ribbon cable in a bent position with the extent of the bend limited to prevent distortion of or damage to the cable. The cable clamp apparatus includes a first and a second member, an inner member positioned inside the bend and an outer member located outside the bend of the ribbon cable, with one of the two members including at least one latch for securing the other member in a fixed relationship while the ribbon cable remains bent but at no greater a bend than the minimum radius. The latch is preferably formed integrally with the outer member, projecting each end at a distance approximately equal to the length of the inner member to hold the inner member in releasable relationship to the outer member while limiting the bend of the ribbon cable to the diameter of the inner member to avoid damage to the cable.
