  • Publication number: 20170354896
    Abstract: 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.

  • Publication number: 20170144096
    Abstract: 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.

  • Publication number: 20160321094
    Abstract: 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.

  • Patent number: 9483291
    Abstract: 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.

  • Patent number: 9378043
    Abstract: 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.

  • Patent number: 9340770
    Abstract: We disclose a particle comprising a matrix coated thereon and having a positive charge, the particle being of a size to allow aggregation of primate or human stem cells attached thereto. The particle may comprise a substantially elongate, cylindrical or rod shaped particle having a longest dimension of between 50 ?m and 400 ?m, such as about 200 ?m. It may have a cross sectional dimension of between 20 ?m and 30 ?m. The particle may comprise a substantially compact or spherical shaped particle having a size of between about 20 ?m and about 120 ?m, for example about 65 ?m. We also disclose a method of propagating primate or human stem cells, the method comprising: providing first and second primate or human stem cells attached to first and second respective particles, allowing the first primate or human stem cell to contact the second primate or human stem cell to form an aggregate of cells and culturing the aggregate to propagate the primate or human stem cells for at least one passage.
