Patent number: 8897316Abstract: Embodiments of the invention include a method for avoiding memory bandwidth utilization during packet processing. The packet processing core receives a plurality of packets. The packet processing core identifies the packet's quality of service (QoS) descriptor. The packet processing core determines that at least one packet should be moved to an off-chip packet stored prior to the packet being transmitted to the egress port. The packet processing core bases that determination, at least in part, on the packet's QoS descriptor. The packet processing core moves the determined packets to the off-chip packet store. The packet processing core determines that at least one packet should not be moved to the off-chip packet store prior to the packet being transmitted to the egress port. This determination is also made, at least in part, based on the packet's QoS descriptor.Type: GrantFiled: December 31, 2010Date of Patent: November 25, 2014Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventors: Edmund Chen, Ramanathan Lakshmikanthan, Ranjit Rozario, Brian Alleyne, Stephen Chow, Patrick Wang, Edward Ho, Thomas Yip, Sun Den Chen, Michael Feng

Publication number: 20120267416Abstract: A safety catch mechanism, comprising a safety catch that is captively attached to the barrel of a nail gun by matching tracks on both said safety catch and said barrel, facing each other, so that said safety catch is allowed to move only in the forward and backward directions along the barrel of the nail gun in the direction of the motion of the nails, is disclosed. A forward pushing means keeps the forward end of the safety catch beyond the muzzle of the nail gun in the initial secured position. As the safety catch is pushed back, the trigger of the nail gun is activated.Type: ApplicationFiled: April 21, 2011Publication date: October 25, 2012Inventors: Raymond Wong, Patrick Wang

Patent number: 7986706Abstract: A hierarchical pipelined distributed scheduling traffic manager includes multiple hierarchical levels to perform hierarchical winner selection and propagation in a pipeline including selecting and propagating winner queues of a lower level to subsequent levels to determine one final winning queue. The winner selection and propagation is performed in parallel between the levels to reduce the time required in selecting the final winning queue. In some embodiments, the hierarchical traffic manager is separated into multiple separate sliced hierarchical traffic managers to distributively process the traffic.Type: GrantFiled: April 29, 2009Date of Patent: July 26, 2011Assignee: Telefonaktiebolaget LM EricssonInventors: Thomas C.

Publication number: 20110062469Abstract: A light emitter includes a light-emitting device (LED) die and an optical element over the LED die. The optical element includes a lens, a window element, and a bond at an interface disposed between the lens and the window element. The window element may be a wavelength converting element or an optically flat plate. The window element may be directly bonded or fused to the lens, or the window element may be bonded by one or more intermediate bonding layers to the lens. The bond between the window element and the lens may have a refractive index similar to that of the window element, the lens, or both.Type: ApplicationFiled: September 17, 2009Publication date: March 17, 2011Applicants: KONINKLIJKE PHILIPS ELECTRONICS N.V., PHILIPS LUMILEDS LIGHTING COMPANY, LLCInventors: Michael D.

Patent number: 5490257Abstract: A method for detecting a half-full condition of a first-in, first-out memory array. The method of the invention includes the steps of a) moving a write pointer through the array to write data to alternating rows of the memory array; b) moving a read pointer through the array to read data from the alternating rows of the memory array in first-in, first-out order; and c) providing a half-full indication when the read pointer and the write pointer point to adjacent rows in the memory array. This method eliminates the need to route lines across the array to detect a half-full condition, thereby reducing die and power requirements and offering an increase in speed.Type: GrantFiled: February 24, 1992Date of Patent: February 6, 1996Assignee: Advanced Micro Devices, Inc.Inventors: Barry A.
