Abstract: A method at an electronic device with a display includes: displaying a user interface having a first region and a second region; receiving, and displaying in the first region of the user interface, a live video stream of a physical environment captured by a remote video camera; displaying, in the second region, a timeline corresponding to a timespan for a first portion of a duration during which the live video stream may have been recorded; in response to receiving a user interaction to move the timespan to a second portion of the duration, transitioning the displayed timeline to a new timeline that corresponds to the timespan for the second portion, and while transitioning, displaying, in the first region, a subset of video frames representing the first and/or second portion of the duration.

Abstract: A wireless proximity detection system employs short-range wireless communication to detect the proximity of a user device within a strictly defined wireless zone and as a result trigger a desired action. The proximity detection system may utilize one or more leaky feeders to define the wireless zone and the associated received signal strength(s) detected by the user's wireless device. Alternatively, a compact planar antenna structure coupled with a highly shielded radio transceiver is used to allow a similar precise low-power radio beam to be emitted defining a small location to enable identification of a wireless device such as a smartphone in a given area in front of the device. The planar antenna structure allows a compact and low-cost fabrication method and the use of common printed circuit fabrication methods provide an integrated solution.

The blade assembly includes a pair of substantially flat wings mounted on the opposite sides of a horizontal rod. The wings are generally rectangular with rounded corners and blunt edges. The wings are oriented at a downward angle relative to the horizontal rod calibrated to enhance the stirring, mixing and blending functions of the apparatus at low rotational speeds.

Abstract: A marinator apparatus for the preparation of pieces of a whole chicken includes a fluid-tight hollow drum with opposing top and bottom walls that are substantially planar and that include an opening with a lid configured to sealingly close the opening. The drum further includes an interior baffle fixed inside that separates the drum into a top compartment accessible only through the top opening and an opposite bottom compartment accessible only through the bottom opening. The drum is supported for rotation by a support axle projecting from one end wall and a drive axle projecting from the opposite end wall. The drive axle includes a driven gear configure to be driven by a powered drive gear.

Abstract: A social networking system may generate a region of an interactive map and determine a zoom level at which the interactive map is being presented. The social networking system may then determine a first defined geographic region based at least in part on the region being displayed and the zoom level at which the interactive map is being displayed. A quantity of content items that exists that are associated with the first define geographic region can be determined by the system. The social networking system may then present, based at least in part on the quantity, a visual representation on the interactive map of one or more content items associated with at least one of the first defined geographic region or a second defined geographic region that encompasses the first defined geographic region.

Abstract: Techniques for providing social network maps are described. For example, a social networking system may receive, from a first user account associated with the social networking system, a content item associated with a location. The social networking system presents a control usable to provide multiple different types of feedback associated with the location. In some examples, the social networking system then generates an interactive map which comprises a visual representation of the content item associated with the location on the interactive map to a second user account. Upon receiving input comprising a selection of a particular type of feedback from among the multiple different types of feedback, the social networking system the performs an action associated with the selected particular type of feedback.

Abstract: Compositions are provided that contain biologically active components of amniotic fluid including growth factors and other proteins, carbohydrates, lipids, and metabolites. The compositions containing biologically active components of amniotic fluid can be useful for a range of therapeutic treatments including joint and soft tissue repair, regulation of skin condition, and for use in organ preservation, such as for use in organ transplant procedures. Advantages of the compositions include that they can be reproducibly produced, without the inherent variability of amniotic fluid from individual donors, and that they are free of fetal waste.

Abstract: A security or identification device comprises a membrane laser structure configured to be optically pumped. The membrane laser structure comprises a flexible emission layer comprising a gain material; and one or more structures formed in or associated with the flexible emission layer and configured to provide optical feedback in the emission layer to produce a laser light output having at least one property representing an identifier.

Abstract: Techniques for providing social network maps are described. For example, a social networking system may receive, from a first user account associated with the social networking system, a text input associated with a multi-author story. In some examples, the social networking system then selects a feed post associated with the multi-author story previously shared by a second user account associated with the social networking system. The social networking system then generates an interactive map which comprises a visual representation of the feed post, and provides the interactive map comprising the visual representation to the first user account.
