Patent number: 9317075Abstract: An example provides an apparatus including a shielding panel in spaced relation to a substrate such that a heat sink mounted on the substrate protrudes through an opening in the shielding panel. A first airflow path may be provided between the substrate and a first side of the shielding panel, and a second airflow path may be provided on a second side of the shielding panel across a portion of the heat sink protruding through the opening.Type: GrantFiled: April 29, 2013Date of Patent: April 19, 2016Assignee: HEWLETT PACKARD ENTERPRISE DEVELOPMENT LPInventors: Kah Hoe Ng, Tzye Perng Poh, Kian Teck Poh

Patent number: 9247624Abstract: A system includes an external light supply to a silicon photonic chip. The light supply includes a primary light source, a secondary light source, an optical coupler, an optical splitter, and a dark sensor. The optical coupler is to combine any output from the primary light source and any output from the secondary light source into an input to the silicon photonic chip. The optical splitter is located in an optical path between the primary light source and the optical coupler, and is to divert part of the output from the primary light source. The dark sensor is to receive the diverted part of the output from the primary light source and to selectively activate the secondary light source based on the diverted part of the output from the primary light source.Type: GrantFiled: January 29, 2013Date of Patent: January 26, 2016Assignee: Hewlett Packard Enterprise Development LPInventors: Jing Kai Tan, Chee How Lee, Kian Teck Poh

Publication number: 20150370014Abstract: Example methods and apparatus to remove dust from an optical waveguide assembly are disclosed. An example apparatus includes a window to be located on an optical waveguide assembly. The example apparatus includes a first piezoelectric member coupled to the window. The first piezoelectric member is to vibrate the window to remove dust from the window in response to an electrical signal.Type: ApplicationFiled: January 24, 2013Publication date: December 24, 2015Inventors: Kian Teck POH, Chee How Lee, Jing Kai TAN

Patent number: 9025496Abstract: A network switching device includes at least two stacking ports, each stacking port being connectable via a stacking cable to a stack including at least one external network switching device. The device further includes an internal communication medium coupled to the stacking ports and capable of transmitting a frequency division multiplexed signal between the stacking ports. The device further includes a network switch and an interface to enable communication between the network switch and the internal communication medium. The interface includes a parallel coupling to the internal communication medium such that a signal with one carrier frequency being communicated between the network switch and the internal communication medium does not interfere with transmission between the two stacking ports of a signal with a different carrier frequency.Type: GrantFiled: January 21, 2014Date of Patent: May 5, 2015Assignee: Hewlett-Packard Development Company, L.P.Inventors: Keng Hua Chuang, Kum Cheong Adam Chan, Kian Teck Poh
