Patent number: 12066875Abstract: In one aspect, a bracket assembly comprises a bracket and a pair of rails. The bracket comprises a first portion which includes a first segment with a first opening and a second segment with a second opening. The pair of rails comprises: a first rail which includes a first tab protruding from the first rail and including a first notch; and a second rail which includes a second tab protruding from the second rail and including a second notch. The bracket is to attach to the pair of rails when: the first portion is placed against the ends of the rails such that the first tab is inserted into the first opening and the second tab is inserted into the second opening; and the bracket is slid down such that the first opening rests in the first notch and the second opening rests in the second notch.Type: GrantFiled: May 23, 2022Date of Patent: August 20, 2024Assignee: Hewlett Packard Enterprise Development LPInventors: Warren A. Kartadinata, Vance B. Murakami, Neil Jefferson Asmussen

Publication number: 20230422424Abstract: One aspect described in the present disclosure provides a faceplate for a computing system. The faceplate includes a die-cast metallic frame and a sheet-metal front face attached to the die cast metallic frame. The die-cast metallic frame includes at least one attachment mechanism protruding beyond the sheet-metal front face for attaching a handle used for insertion or ejection of hardware attached to the faceplate. This configuration allows the die-cast metallic frame to bear a force associated with insertion or ejection of the hardware. Furthermore, the sheet-metal front face does not bear the force associated with insertion or ejection of the hardware.Type: ApplicationFiled: June 24, 2022Publication date: December 28, 2023Inventors: Warren A. Kartadinata, Robert E. Cayou, Harold Zin Htutt

Patent number: 11839029Abstract: One aspect provides an apparatus for locking circuit boards in position between a pair of guide rails. The apparatus can include a slider attached to a sidewall of one guide rail. The slider is allowed to slide along the guide rail within a predetermined range and one or more plunger-and-spring assemblies. A respective plunger-and-spring assembly comprises a plunger and a spring surrounding the plunger, and the plunger is inserted into a through-hole on the sidewall of the guide rail such that a first end of the plunger can be aligned with a notch on a corresponding circuit board and a second end of the plunger is in contact with the slider. Sliding of the slider causes the spring to compress and decompress and the first end of the plunger to move in and out of the notch on the circuit board, thereby facilitating locking and unlocking of the circuit board.Type: GrantFiled: May 24, 2022Date of Patent: December 5, 2023Assignee: Hewlett Packard Enterprise Development LPInventors: Warren A. Kartadinata, Neil Jefferson Asmussen, Vance B. Murakami

Publication number: 20230389211Abstract: One aspect of the instant application provides an apparatus for locking a circuit board in position. The apparatus can include a cam latch, a plunger, and a hinge pin coupling the cam latch and the plunger. The cam latch is positioned to rotate around the hinge pin, and the rotation of the cam latch causes a linear motion of the plunger in a plane parallel to a component-mounting surface of the circuit board, thereby facilitating locking and unlocking of the circuit board.Type: ApplicationFiled: May 24, 2022Publication date: November 30, 2023Inventors: Warren A. Kartadinata, Neil Jefferson Asmussen, Vance B. Murakami

Patent number: 11632867Abstract: Example implementations relate to a cable management arm for a computing system. The cable management arm includes a pair of latches, a pair of first bars, and a second bar. The pair of latches is detachably connectable to a chassis of the computing system. Each first bar has a first end pivotably connected to a respective latch of the pair of latches, and a second end connected to the second bar for defining an open space therebetween. The open space provides a non-interfering entrance for accessing the one or more electronic components from rear side of the chassis. The second bar supports the cables connected to the one or more electronic components. The pair of first bars is pivotable relative to the pair of latches such that the second bar is movable to a plurality of preset positions for providing the clearance from the cables during service event, for instance.Type: GrantFiled: September 9, 2021Date of Patent: April 18, 2023Assignee: Hewlett Packard Enterprise Development LPInventors: Warren Kartadinata, Vance Murakami

Patent number: 9781798Abstract: An LED based illumination device includes a plurality of LEDs that emit light through an output port of a housing. The LED based illumination device includes a heat sink that is in thermal contact with the plurality of LEDs. A peripheral electrical circuit board is configured to be contained within the housing, e.g., surrounding at least a portion of the heat sink. The peripheral electrical circuit board may include a radio frequency (RF) transceiver configured to communicate data between the LED based illumination device and another electronic device. A primary electrical circuit board may be electrically coupled to the peripheral electrical circuit board and electrically coupled to the plurality of LEDs.Type: GrantFiled: April 7, 2016Date of Patent: October 3, 2017Assignee: Xicato, Inc.Inventors: Gerard Harbers, Barry Mark Loveridge, Martin Emil Mueller, Peter K.
