Abstract: An optical sight for a firearm can be provided with multiple light sources for illuminating one or more aiming marks on the sight. The light sources may be multiple LEDs, e.g. of different colors that can provide illumination in different lighting conditions. The lights sources may also be physical process driven light sources, such as a Gaseous Tritium Light Source (GTLS). A combination of LEDs and GTLS may also be used. The light sources may be disposed at multiple focal points of a multi-lens system. Alternatively, a selector may be used to selectively locate one of the light sources at the focal point of a single lens system. The optical sight may be a reflex sight, e.g. for a handgun, or may be a riflescope for a rifle.

Abstract: Systems and methods for generating social annotations for content that are capable of being seen by a broad audience are provided herein. A system can include a user identification component configured to identify a user that has potential for generating a valuable endorsement of a content item based at least in part on a sharing setting associated with a user. The system further includes an audience component configured to determine an audience associated with the user based at least in part on the sharing setting, a user selection component configured to select the user as a candidate user for generating the endorsement of the content item in response to a determination that a size of the audience exceeds a threshold, and a targeted content component configured to, in response to selection of the user, provide the content item to the user with a capability to endorse the content item.

Abstract: A persistent media player is disclosed. A method for providing the persistent media player includes displaying, by an electronic device, a first portion of a scrollable document in a user interface (UI) of an application executed on the electronic device. The first portion includes a media player that is to present a first media item. The method further includes receiving an input to scroll to a second portion of the scrollable document. The method also includes displaying the second portion of the scrollable document, where the first portion is no longer visible and where the media player continues to be visible.

Abstract: An immersed membrane cassette has a high tank intensity achieved by one or more of: reduced module to module gap; using structural hollow tubing in at least parts of a frame in place of separate permeate and/or air pipes; and, using vertical permeate port connections. The cassette has a tank intensity over 650 m2/m2. The cassette may be combined with a fine screen. This specification also describes an immersed membrane module having a permeate port and/or connector on the top of a header. The permeate connection between the module and a permeate collection tube may be vertical, i.e. perpendicular to the length of the header. A piston seal may be used between the permeate port of the header and the permeate collection tube. The permeate collection tube may be a horizontal structural member on the periphery of a frame that holds the module.

Abstract: A chair support shell has an integral back portion, seat portion, and joining portion between the back portion and the seat portion. At least a major portion of the support shell comprises a compliant structure, the compliant structure having a plurality of cells interconnected by a plurality of resilient members. The compliant structure provides compliance in the seat portion, compliance in the back portion, and compliance in the joining portion. The compliant structure enables recline of the back portion relative to the seat portion.

Abstract: A method for presenting content items includes receiving a first content item from a first user device of a first user of a content sharing platform. The first content item references an additional content item through one or more actions performed by the first user on the first user device. In response to a subsequent request of a second user of the content sharing platform for the first content item hosted by the content sharing platform, providing, for display in a graphical user interface (GUI) of a second user device of the second user, a first GUI portion to display the first content item and a second GUI portion to present the additional content item. The one or more actions are caused to be performed in the GUI of the second user device during a playback of the first content item.

Abstract: Assemblies for supporting a load relative to a roof of a vehicle, and vehicle roof tray assemblies are disclosed. Disclosed assemblies include an elongate member and an engaging mechanism. The elongate member defines a support surface for supporting the load, and has a pair of opposed, diverging retention surfaces extending away from the support surface. The engaging mechanism is configured to abut the retention surfaces to engage the elongate member. A slat for a vehicle roof tray is also disclosed.

Abstract: A server can receive a seed keyword to generate additional keywords relevant to the seed keyword. The server can identify, using a semantic relationship graph, keyword categories. Each keyword can have a semantic distance from the seed keyword less than a threshold. The server can generate, for each keyword of the keyword categories, a keyword-seed affinity score based on a frequency of the keyword occurring with the seed keyword on an information resource. The server can determine, for each keyword category, a category-seed affinity score based on the keyword-seed affinity scores for each of keyword in the keyword category. The server can compare each category-seed affinity score a threshold. The server can transmit, for display, the keywords. One keyword category can be indicated as selected and another keyword category can be indicated as unselected based on the comparison.
