摘要:
An acetal-based composition useful as a nucleating, gelling, thickening or clarifying agent is disclosed. The composition may be synthesized or provided in many different forms, including multicarbon diacetals formed from carbohydrates. Once synthesized, the compound may be employed as an additive in a plastic composition, such as (for example) a polypropylene copolymer. One structure of such an acetal-based composition is provided by the formula: wherein: n is 0, 1 or 2; Ar1 and Ar2 are independently selected from substituted or unsubstituted aryl-containing groups; and R is selected from the group consisting of: alkenyls, alkyls, alkoxy, hydroxyl alkyls, and alkyl-halides.

摘要:
An acetal-based composition useful as a nucleating, gelling, thickening or clarifying agent is disclosed. The composition may be synthesized or provided in many different forms, including multicarbon diacetals formed from carbohydrates. Once synthesized, the compound may be employed as an additive in a plastic composition, such as (for example) a polypropylene copolymer. Co-additives may also be employed. Several aryl structures may reside upon the hydrocarbon chain backbone. One structure of such an acetal-based composition which happens to have two aryl-containing groups is shown: wherein: n is 0, 1 or 2; Ar1 and Ar2 are independently selected from substituted or unsubstituted aryl-containing groups; and R is selected from the group consisting of: alkenyls, alkyls, alkoxy, hydroxyl alkyls, and alkyl-halides.

摘要:
A field-replaceable printed circuit board (“PCB”) cable assembly comprises at least one field-replaceable PCB, at least one cable, a connector with a plurality of beams, and top and bottom hood portions. A first end of the at least one field-replaceable PCB is attached to the at least one cable, and a second end of the at least one field-replaceable PCB is attached to the plurality of beams. The at least one field-replaceable PCB can be replaced by disassembling the hood portions, detaching the at least one field-replaceable PCB from the plurality of beams, and attaching at least one new field-replaceable PCB.
摘要:
A low-profile, right angle connector assembly comprises six cable connectors and six board-mount connectors housed within a PCIe bracket and EMI shell. The PCIe bracket and EMI shell are braced to a low profile PCIe card. Each board-mount connector is designed to receive a cable connector and allows for the transmission and processing of high-speed data with lower latency. A removable latch mounted on the cable connectors helps ensure the cable connectors remain physically connected to the board-mount connectors. The removable latch may be replaced as needed for breakage and wear and tear.

A right angle transition adapter allows vertical connector components to be used in a right angle connector. The right angle transition adapter comprises a vertical connector housing, a wafer, overmolded lead frames, and a right angle transition housing. The overmolded lead frames can be mounted to a board while the vertical connector housing can connect with mating connectors as if it were a vertical connector.

摘要:
A method and system of managing resource lease duration for on-demand computing is provided. The system can include one or more resources having a metric capturing tool; and a provisioning manager in communication with the one or more resources. The provisioning manager can receive a request for at least one resource from the requester. The provisioning manager can provision the at least one resource from the one or more resources. The metric capturing tool can communicate one or more metrics associated with performance of the at least one resource to the provisioning manager. The provisioning manager can determine a lease modifier based at least in part on the one or more metrics. The provisioning manager can adjust a lease duration for the at least one resource based at least in part on the lease modifier.
摘要:
A system is presented that comprises a third-party ad provider that serves advertisements to different websites being viewed at a plurality of display devices. The advertisements may be from different advertisers, and may include advertisements from a content service provider. The advertisements from the service provider may include a promotion for a video program presented by the service provider and may provide a selectable option for a viewer of the website to have that viewer's DVR service automatically programmed to record the promoted video program. The selectable option may be selected with a single action by the viewer, and all communications, associations between the display device and the DVR service, and programming of the DVR service may occur automatically without intervention by the viewer.
