Publication number: 20170354896Abstract: A mannequin of a human torso adapted to retain otherwise handheld devices for simulation purposes is provided. The mannequin may have a plush shell covering filled with polymer stuffing except for a cavity therein, wherein the cavity communicates to a cavity opening defined by the shell covering. An elastic sleeve may be dimensioned and adapted to line the cavity yet protrude from the cavity opening, so that the sleeve opening is concomitant with the cavity opening. Operatively engaged along a peripheral portion of the sleeve, slightly inward for the sleeve opening, a peripheral drawstring adapted to selectively decrease the peripheral portion of the sleeve is disposed to removably retain the handheld device within the sleeve.Type: ApplicationFiled: June 9, 2016Publication date: December 14, 2017Inventor: Allen CHEN

Publication number: 20170144096Abstract: A vacuum filter which is resistant to hot debris and which prevents damage to the vacuum when damaged is disclosed. The vacuum filter may include a filter element which is formed of multiple layers of different material. The filter element may include an upstream layer of filter material which is exposed to incoming debris and which filters debris from air moving through a vacuum, a firebreak layer disposed adjacent the upstream layer of filter material and disposed downstream of the upstream layer of filter material, and a downstream layer of filter material which is disposed downstream of the firebreak layer. The firebreak layer and downstream layer of filter material may prevent damage to the vacuum and maintain the filtration ability of the filter if the upstream layer of filter material is damaged.Type: ApplicationFiled: November 25, 2015Publication date: May 25, 2017Applicant: DUSTLESS DEPOT, LLCInventors: Allen Chen, Zhifeng Xia

Publication number: 20160321094Abstract: A virtualization platform for Network Functions Virtualization (NFV) is provided. The virtualization platform may include a host processor coupled to an acceleration coprocessor. The acceleration coprocessor may be a reconfigurable integrated circuit to help provide improved flexibility and agility for the NFV. The coprocessor may include multiple virtual function hardware acceleration modules each of which is configured to perform a respective accelerator function. A virtual machine running on the host processor may wish to perform multiple accelerator functions in succession at the coprocessor on a given data. In one suitable arrangement, intermediate data output by each of the accelerator functions may be fed back to the host processor. In another suitable arrangement, the successive function calls may be chained together so that only the final resulting data is fed back to the host processor.Type: ApplicationFiled: April 28, 2015Publication date: November 3, 2016Inventors: Abdel Hafiz Rabi, Allen Chen, Mark Jonathan Lewis, Jiefan Zhang

Patent number: 9483291Abstract: A virtualization platform for Network Functions Virtualization (NFV) is provided. The virtualization platform may include a host processor coupled to an acceleration coprocessor. The acceleration coprocessor may be a reconfigurable integrated circuit to help provide improved flexibility and agility for the NFV. To help improve performance predictability, a hierarchical accelerator registry may be maintained on the coprocessor and/or on local servers. The accelerator registry may assign different classes and speed grades to various types of available resources to help the virtualized network better predict certain task latencies. The accelerator registry may be periodically updated based on changes detected in the local storage and hardware or based on changes detected in remote networks.Type: GrantFiled: January 29, 2015Date of Patent: November 1, 2016Assignee: Altera CorporationInventors: Allen Chen, Abdel Rabi

Patent number: 9378043Abstract: A virtualization platform for Network Functions Virtualization (NFV) is provided. The virtualization platform may include a host processor coupled to an acceleration coprocessor. The acceleration coprocessor may be a reconfigurable integrated circuit to help provide improved flexibility and agility for the NFV. The traffic at the NFV platform may be controlled by a distributed Quality of Service (QoS) manager. The distributed QoS manager may include multiple QoS modules each of which serves to perform priority queuing independently for its associated component or interface. For example, the NFV platform may include a first QoS module for arbitrating among multiple virtual machines, a second QoS module for performing priority queuing for data packets received at an external network port, a third QoS module for arbitrating among memory accesses at a coprocessor external memory interface, fourth QoS module for arbitrating accesses among multiple hardware acceleration slices, etc.Type: GrantFiled: May 28, 2015Date of Patent: June 28, 2016Assignee: Altera CorporationInventors: Jiefan Zhang, Alexander Kugel, Allen Chen, Mark Jonathan Lewis, Abdel Hafiz Rabi
