  • Publication number: 20190299148
    Abstract: Filters and filter assemblies including one or more shield elements to protect the filter media of the filters during installation of the filters into a filter housing of the filter assembly are provided. A filter includes first and second media packs, a housing seal system, a handle and a shield element. Filter media packs extend from a first end to a second end in a diverging manner. The first end has a length dimension and a width dimension that extend transversely. A shield element projects over the first and second media packs at the first end a span in the width direction of at least 40% of the width dimension defined by the first and second media packs and projecting a span in the length direction of at least 5% of the length dimension defined by the first end.

  • Patent number: 10354287
    Abstract: When the social networking system selects an advertisement for presentation to the user by a client device, a content identifier associated with the selected advertisement is stored in an advertisement history associated with the user. When the user performs a conversion event associated with the selected advertisement, the social networking system receives a content identifier and a user identifier from a client device used that performed the conversion event and retrieves the user's advertisement history. If the retrieved advertisement history includes a content identifier for the selected advertisement matching the content identifier received from the client device and a time between the conversion event and providing the selected advertisement to the client device is less than a threshold time period, a fee is determined for presentation of the selected advertisement.

  • Patent number: 9573802
    Abstract: The disclosure generally relates to method and apparatus for forming three-dimensional MEMS. More specifically, the disclosure relates to a method of controlling out-of-plane buckling in microstructural devices so as to create micro-structures with out-of-plane dimensions which are 1×, 5×, 10×, 100× or 500× the film's thickness or above the surface of the wafer. An exemplary device formed according to the disclosed principles, includes a three dimensional accelerometer having microbridges extending both above and below the wafer surface.

  • Publication number: 20170014743
    Abstract: A filter element and multi-component holding assembly for a filter element is provided. The filter element includes first and second media panels, a support frame, a base frame and first and second end cap structures. Each filter media panel defines first, second, third and fourth sides. The first and second sides extend between the third and fourth sides. The support frame maintains the first and second filter media panels in a spaced orientation forming a cavity therebetween. The base frame defines a first opening in fluid communication with the cavity. The first end cap structure seals the third side of the first and second filter media panels and the second end cap structure seals the fourth side of the first and second filter media panels. The base frame has a first portion captured in the first end cap structure and a second portion captured in the second end cap structure.

  • Patent number: 9440324
    Abstract: In an angle valve, an externally threaded sleeve within the yoke surrounds the stem at an upper end of the stem. A yoke bushing fixed to the valve has internal threads matching with the external threading of the sleeve. A split collar assembly is located on the stem above the sleeve. The stem has a greater diameter itself, and/or via a nut, at a lower portion of the stem (below the sleeve) relative to the upper portion of stem. The plug stem is designed to pass through the yoke bushing making it possible to perform the normal open-close operation and grinding operation independently.

  • Patent number: 9156037
    Abstract: A microfluidic device for separating target components from a source fluid includes one or more source channels connected to one or more collection channels by one or more transfer channels. The target components of the source fluid can be magnetic or bound to magnetic particles using a know binding agent. A source fluid containing magnetically bound target components can be pumped through the source channel of the microfluidic device. A magnetic field gradient can be applied to the source fluid in the source channel causing the magnetically bound target components to migrate through the transfer channel into the collection channel. The collection channel can include a collection fluid that is stagnant until a predefined volume of source fluid is processed or a predefined volume of target components accumulate in the collection channel, at which point collection fluid can be pumped into the collection channel to flush the target components out of the collection channel.

  • Publication number: 20150227977
    Abstract: An online system receives one or more business rules associated with a third party system that associates online system users with an audience group based on characteristics of the user. When an online system user interacts with content provided by the third party system via a client device, contextual information describing the interaction is communicated from the client device to the online system. By applying one or more business rules to the contextual information, the online system associates the user with one or more audience groups. The online system determines that the user is eligible to be presented with the advertisement based at least in part on the one or more audience groups associated with the user and the one or more of the audience groups specified by the advertiser associated with the advertisement. And if eligible, the online system provides the advertisement to the client device for presentation.

  • Patent number: 9027276
    Abstract: The invention relates to an insect trap which has been designed to facilitate simple and efficient servicing, maintenance and cleaning. The trap includes a back housing; a frame swing mounted to said housing; and a cover comprising openings allowing insects to enter the trap and the frame supports at least one light such that said frame and lights can be moved from a first position where they overlie the back housing, to a second position where they lie clear of the back housing such that an insect catching means which may be fitted over the back housing is readily accessible for replacement during servicing. Additionally, the trap is adapted for ease of servicing and jet cleaning by the provision of shields each of which sealably protect, from water ingress, the plurality of lights at the positions where they connect to electrical fittings.

  • Publication number: 20140214558
    Abstract: As components of an advertisement are received by an online system, the online system determines whether the received components satisfy one or more policies of the online system. If a component does not satisfy a policy of the online system, the user providing the components is notified when the component is provided, allowing the user to modify the component. Additionally, stored data describing previously analyzed components are compared to received components, and the stored data is used if the received component matches a previously analyzed component This process expedites approval of advertisements by the online system.
