Patent number: 6960719Abstract: The present invention is directed to a method and apparatus for mitigating electromagnetic waves emanating from an electronic device. The apparatus comprises a cover member, a bight extending from one end of the cover member, and a retaining plate spaced from the cover member and connected to the bight to provide a biasing force away from the cover member and towards an electronic device. The cover member is configured to overlie an opening in the chassis of the electronic device and the retaining plate is configured to abut cabling extending out of the chassis. In this way, the apparatus attenuates electromagnetic waves radiating emanating from an opening in a chassis of an electronic device and conducted along cabling as a noise signal superimposed upon the intended signal.Type: GrantFiled: October 20, 2003Date of Patent: November 1, 2005Assignee: Hewlett-Packard Development Company, L.P.Inventors: Eugene Arthur Miksch, Robert J. Blakely

Patent number: 6618266Abstract: A capacitor mounting method and resulting printed circuit board that increases the mounting density of both vias and decoupling capacitors is presented. Vias are shared between capacitors mounted on the top and bottom of the printed circuit board. This arrangement allows increased decoupling capacitor density and avoids the current doubling problem when shared vias are connected with capacitors installed on the same side of the board.Type: GrantFiled: March 6, 2001Date of Patent: September 9, 2003Assignee: Hewlett-Packard Development Company, L.P.Inventors: Robert J. Blakely, John S. Atkinson

Patent number: 6470408Abstract: An apparatus and a method are provided to distribute interrupts from a system bus to Intel® Architecture (IA)-32 applications processors. The apparatus includes a bridge that couples a processor bus to the system bus. In addition, the bridge is coupled to an advanced programmable interrupt controller (APIC) by an APIC bus. The bridge monitors the system bus for interrupts and converts selected interrupt transactions into APIC messages. The bridge then sends the APIC messages to the APIC bus. Each of the applications processors is also coupled to one of many APIC buses. The applications processor that is the target of the interrupt transaction receives the APIC message and executes an interrupt handler routine. The apparatus and method also incorporate interrupt transaction buffering and throttling.Type: GrantFiled: April 14, 1999Date of Patent: October 22, 2002Assignee: Hewlett-Packard CompanyInventors: John A. Morrison, Robert J. Blakely, Leo J. Embry, Michael S. Allison

Patent number: 6381663Abstract: An apparatus and method for permitting bus locking in a computer system having a mixed architecture. The mixed architecture includes a first bus coupled to processors that may run applications using bus locking or cache line locking. The apparatus interfaces the first bus with a second bus that does not support bus locking. The apparatus when presented with a locked transaction effectively implements bus locking on the second bus.Type: GrantFiled: March 26, 1999Date of Patent: April 30, 2002Assignee: Hewlett-Packard CompanyInventors: John A. Morrison, Robert J. Blakely, Eric M. Rentschler, John R. Feehrer
