Abstract: Systems, methods and non-transitory computer readable media for optimizing visual contents are provided. A particular mathematical object corresponding to a particular visual content in a mathematical space including a plurality of mathematical objects corresponding to visual contents may be determined. The mathematical space and the particular mathematical object may be used to obtain first and second mathematical objects of the plurality of mathematical objects. The visual content corresponding to the first mathematical object may be used in a communication with a first user and the visual content corresponding to the second mathematical object may be used in a communication with a second user. Indications of the reactions of the first and second users to the communications may be received. A third visual content may be obtained based on the reactions. The third visual content may be used in a communication with a third user.

Abstract: A system includes a tray (44), a printing assembly (22), an axis mechanism (10), a coupling mechanism (88) and a cover (54). Tray (44) configured for placing thereon a sample (70) including a first flowable-matter substrate (FMS) (69). Printing assembly (22) configured to print an image of edible substance on a second FMS layer (68) formed on first FMS (69). Axis mechanism (10) configured to control a distance (41) between sample (70) and printing assembly (22) by moving tray (44) with sample (70) along a vertical axis. Coupling mechanism (88) configured to couple between axis mechanism (10) and tray (44). Cover (54) configured to cover axis mechanism (10). Cover (54) has a front surface (77) that faces sample (70), and configured to block a spillage of at least one of the first and second FMSs (69, 68) from wetting the axis mechanism (88).

Abstract: According to one aspect of the present disclosure, a sidewalk shed section can include a first and second pair of leg sections, wherein at least a portion of each leg section is plus-shaped, and each leg section can include a rod header located at a top end of the plus-shaped portion; at least one hole located at a bottom end of the plus-shaped portion; and a bracket configuration.

Abstract: A screening platform enables comprehensive ocular evaluations. The screening platform includes a harness that is configured to fit a head of a patient and that includes one or more electronic components that are operable to power an interchangeable module, a central processing unit (CPU) with a graphical processing unit (GPU), and the interchangeable module with communication capabilities to external computational devices, multiple display output devices, and several types of input devices from both an operator and a patient at-hand, wherein the interchangeable module is separable from the screening platform.

Abstract: Methods and systems are for aligning a light projection engine (e.g., in a virtual reality headset) are described. An assembly for aligning the light projection engine includes a frame, an optical waveguide assembly; and the light projection engine. Embodiments include assemblies for aligning based on a pivot point, an optical axis, an X, a Y, and a Z axis, and with six degrees of freedom. In addition, an embodiment includes three planar joints that allow for alignment of the light projection engine.

Abstract: Methods and systems are provided to assemble an optical waveguide assembly. An optical waveguide assembly may be used in a virtual reality headset or other type of projection system. The optical waveguide assembly includes a front lens, one or more optical waveguides, and a back lens. In one embodiment, an insert is used that is the same width as the optical waveguides to prevent cracking of the optical waveguides. In another embodiment, the optical waveguide assembly includes Optically Clear Adhesive (OCA) tape between the different elements of the optical waveguide assembly to precisely align the optical waveguides. In another embodiment, the optical waveguide assembly has cover portions or a frame that protect the optical waveguides in the optical waveguide assembly.

Abstract: An appliance such as a refrigerator or freezer comprising a base having a drawer, a foldable step assembly received in the drawer is disclosed. The step assembly is configured to rise out of the drawer into an extended position to provide a step when the drawer is open.

Abstract: A cable dispensing system is disclosed which includes multiple parallel coils of flexible non-insulated cables separated by multiple parallel insulating discs. The insulating discs have hubs to which the inner portions of the coils are fixedly coupled. The insulating discs and coils are disposed within a housing, which is rotatably coupled to the multiple parallel insulating discs and fixedly coupled to each outer portion of the multiple coils. The cables comprising the coils are routed from the inner portions through tunnels, which extend through the insulating discs in paths parallel to the axis of the parallel insulating discs. When cords attached to the housing are extended, the coils become wound, creating an electrical short between adjacent loops of the spiral coil. The shorter conductive path reduces the amount of energy that is lost as heat.
