Abstract: A pump having a rotor that is rotatable about a rotation axis and comprises a rotor hub and a rotor collar that extends from the rotor hub in the radial direction and encircles it in an undulating manner, a pump housing which forms a pump duct with the rotor, said pump duct connecting a first inlet/outlet space to a second inlet/outlet space and a blocking device which is arranged between the first inlet/outlet space and the second inlet/outlet space and which comprises a blocking element which blocks the pump duct in the axial direction on both sides of the rotor collar. The blocking device has a first seat and a second seat for the blocking element, wherein the spacing between the first seat and the second seat in the circumferential direction is greater than the spacing between a first contacting face and a second contacting face of the blocking element in the circumferential direction.

Abstract: A blocking device for a pump having a rotor that is rotatable about a rotation axis in a pump duct and comprises a rotor hub and a rotor collar that extends from the rotor hub in the radial direction and encircles it in an undulating manner, wherein the blocking device comprises a plurality of blocking elements which are configured to block the pump duct in the axial direction on both sides of the rotor collar, wherein each of the plurality of blocking elements has a slot with a U-shaped sealing profile for abutting against the rotor collar, a sealing face for abutting against the rotor hub, and two contacting faces for abutting against a seat of the pump duct and/or against a contacting face of another blocking element of the plurality of blocking elements, and to a pump having a corresponding blocking device.

Abstract: A census server provides measurement reports describing clients accessing a specified network-based service to a measurement agency via a network. The census server receives census events from clients used by users via the network. The census events describe usage of a network-based service by the clients. The census server processes the census events to produce measurement reports describing the usage of the network-based service. The processing includes filtering specified information out of the census events to prevent the measurement reports from identifying the users of the clients. The measurement agency may use the measurement reports, for example, to describe how the clients tend to access and use the service.

Abstract: A request of a channel owner is received to enable an online community option to facilitate communications between the channel owner and viewers of a channel of the channel owner on a content sharing platform. The online community option is associated with the channel in a data store, and a channel GUI comprising a GUI element representing the online community option is provided for presentation to the channel owner. An online community GUI is provided to allow the channel owner to submit a post to initiate online conversation with viewers of the channel. The channel GUI is provided for presentation to a viewer of the channel. In response to a selection of the GUI element representing the online community option, the online community GUI comprising the post of the channel owner is provided, and the viewer of the channel is allowed to respond to the post.

Abstract: A computer-implemented method of determining reaction to promotional items includes providing to a mobile device a promotional item associated with a geographic location, determining whether the mobile device is proximate to the geographic location, and charging an advertising account if the mobile device is proximate to the geographic location.

Abstract: Described herein are LED chips incorporating self-aligned floating mirror layers that can be configured with contact vias. These mirror layers can be utilized to reduce dim areas seen around the contact vias due to underlying material layers without the need for the mirror layer to be designed at some tolerance distance from the electrical via. This increases mirror area, eliminating lower light reflection in the proximity of the via and producing higher light output with greater light emission uniformity. In some embodiments, the mirror layer is formed with a contact via. This allows for a self-aligning process and results in the mirror layer extending substantially from the edge of the via.

Abstract: A system and method for generating a plurality of personas for an account of a user is disclosed. The present invention uses an account engine to receive information for the plurality of personas and to associate the information for the plurality of personas to the account. The information for each of the plurality of personas includes a visibility level. A persona engine receives a selection from the user and transmits the selected persona to the user based on the selection. An authority engine determines an appearance of the selected persona based on the visibility level.

Abstract: Document load times may be determined by (a) accepting a first set of one or more document identifiers, (b) for each of the one or more document identifiers of the first set, requesting the document, downloading the document, and rendering the document, and (c) determining a first elapsed time from about the time of requesting a first document identified by the first set of one or more document identifiers to about the time of completion of the rendering of a last document identified by the first set of one or more document identifiers. This may be repeated for a second set of documents. For example, a first set of document(s) may be located at a first serving facility and the second set of document(s) may be located at a second serving facility.
