Abstract: Systems and methods for controlling video functions across multiple video streams are provided. Multiple video streams are recorded at an event via a corresponding multiple of video sources, the multiple video streams being synchronized in time with each other. The multiple video streams are displayed on a display device. One or more of the multiple video streams may be selected via a touch screen of the display device, which are then presented for playback on the display device. Control of video functions of the selected video streams is enabled via finger gestures on the touch screen of the display device. The video functions may comprise video selection, play, pause, fast forward, rewind, zoom, focus, shuttle, scrub, seek, frame advance, and the like. In the event two or more of the multiple video streams are selected, the two or more video streams may be controlled simultaneously and synchronously.

Abstract: The lockable pivot joint can be connected to separate, first and second shaft members to facilitate pivotable connection of the shaft members. The pivot joint includes a first joint member and a second joint member pivotally connected to the first joint member. A push-button assembly for locking and un-locking the pivot joint in a plurality of positions, is connected to the members. The push-button assembly includes an elongate shank having a button at one end. A lobed member is attached to the first end of the shank and a retainer member is positioned in communicating relation with the elongate shank to secure the lobed member on the elongate shank. A biasing member is positioned between the button and the second joint member.

Abstract: A modular mattress assembly comprises a mattress unit that includes multiple mattress blocks each having a top face, a bottom face and a surrounding surface, and multiple connecting units each provided on the surrounding surface of a corresponding mattress block. The mattress blocks are arranged such that the top faces of the mattress blocks constitute a top support surface of the mattress unit. Any two adjacent mattress blocks are connected to each other through connection between the connecting units provided respectively thereon.

Abstract: A single-handle faucet includes a faucet body which has an open top and which is formed with a spout, an upright water pipe provided inside the faucet body, and a cartridge stem extending slidably into the upright water pipe and being movable between a first position, in which water flow from the water pipe to the spout is permitted, and a second position, in which water flow from the water pipe to the spout is not permitted. A cover unit is mounted on the open top of the faucet body and has an apex that is formed with a curved slit. A driving piece has a pair of opposite pivot arms which extend downwardly through the curved slit and which have lower ends pivoted to the cover unit, and a curved extension which extends downwardly through the curved slit and which is in sliding contact with an inner wall surface of the cover unit. The curved extension is formed with a toothed inner surface. A driven piece is connected to a topmost end of the cartridge stem and has a rack formed thereon.
