Patent number: 11789220Abstract: Various apparatus are disclosed for lifting heat sinks during insertion of optical modules into transceiver cages (e.g., housings). The apparatus also provide for lifting of the heat sink during removal of the optical modules from the transceiver cages. While the heat sink is lifted during insertion or removal, the heat sink is in contact with the surface of the optical module when the optical module is fully inserted in the transceiver cage. Lifting of the heat sink during insertion and removal of the optical module allows a thermal interface material (TIM) to be placed on the surface of the heat sink in contact with the optical module to improve thermal conduction between the optical module and the heat sink.Type: GrantFiled: March 28, 2022Date of Patent: October 17, 2023Assignee: Amazon Technologies, Inc.Inventors: Tri Nguyen, Hogan Lew, Srinivas S. Chebrolu

Patent number: 8842687Abstract: An exemplary embodiment provides for methods, apparatuses and systems to facilitate the detection of network device failures in a variety of network topologies. This is accomplished by equipping a network device, or other devices used in conjunction with network devices, with a bypass port or network interface, such as a secondary outgoing network traffic communication port. In a normal operating mode, network traffic received at a first network interface or port is forwarded, after processing on the packet processing path of the network device, from a second network interface or port. In one implementation, the second network interface or port and the bypass port or network interface are connected to corresponding interfaces of a router or two routers. When a network device failure occurs network traffic bypasses the packet processing path of the network device and is forwarded from the bypass port or interface.Type: GrantFiled: June 30, 2006Date of Patent: September 23, 2014Assignee: Blue Coat Systems, Inc.Inventors: Simon Adrian Jackson, Hogan Lew

Patent number: 8068340Abstract: A reversible fan tray device is provided for a power supply unit. The fan tray device includes a mounting panel to be removably mounted to the power supply, a fan unit secured to the mounting panel to provide airflow through the electronic device, and an interconnection board secured to the mounting panel to provide an electrical connection between the fan unit and the power supply unit. The mounting panel can be positioned in either of two orientations, the first orientation to draw external air into the power supply unit and the second orientation to force internal air out of the power supply unit. The interconnection board mates with a connector on the power supply unit when the fan tray cassette is in either of the two orientations. The interconnection board provides an airflow direction indication to the power supply unit for an existing orientation of the two orientations.Type: GrantFiled: June 26, 2009Date of Patent: November 29, 2011Assignee: Juniper Networks, Inc.Inventors: Tri Luong Nguyen, Ankur Singla, Hogan Lew, Stephen Strong
