Abstract: Provided herein are polypeptides that bind to a transferrin receptor, methods of generating such polypeptides, and methods of using the polypeptides to target a composition to a transferrin receptor-expressing cell.

Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for customized vehicle operator workflows. A vehicle operator workflow includes a set of tasks to be completed by a vehicle operator. The vehicle operator workflow may be presented to the vehicle operator upon satisfaction of a triggering event, such as upon the vehicle operator logging into an account or the vehicle entering a specified geographic region. The vehicle operator workflow may enable the vehicle operator to complete the individual tasks as well as submit evidence that the tasks have been completed.

Abstract: Eyeglasses includes a frame, two connecting blocks, and two temples. A front end of each connecting block is pivotably connected to a side of the frame. A rear end of each connecting block includes an axle having a first positioning portion. A rear end of each temple has a hook. A front end of each temple includes a receptacle receiving one of the axles. The receptacle of each temple includes an inner periphery having a second positioning portion engaged with the first positioning portion of one of the connecting blocks, such that the temples are pivotable relative to the connecting blocks to change an angular position of each hook. The first and second positioning portions engage with each other to fix the angular position of the hook. A disengagement prevention mechanism is provided between each temple and one of the connecting blocks.

Abstract: A cover for hiding slats of an upper bunk is disclosed. The cover may be wrapped around the head and foot slats of the upper bunk or around left and right rails of the upper bunk. The cover is tensioned with a strapping mechanism to hold the bottom side of the cover in a substantially flat configuration. Moreover, an intermediate strap may be strapped around an intermediate slat to further maintain the substantially flat configuration of the bottom side of the cover. Flaps may also be attached to the bottom side of the cover and be traversable between first and second positions to display two or more motifs. The cover serves to conceal the aesthetically displeasing slats and also to provide a protective barrier over the splinters on wooden slats.

Abstract: Goggles include a body having a lens. A front face of the lens includes two side view sections corresponding to two eyes of a wearer and a central section corresponding to a nose of the wearer. At least one protrusion is formed on the central section and protrudes from the front face of the lens. A transparent film has a width larger than a width of the lens in a width direction. The transparent film is mounted to the front face of the lens and extends over the side view sections and the central section of the lens, with a distal end of the at least one protrusion abutting the transparent film. An actuating device is mounted to the body and coupled to the transparent film. The actuating device is operable to move the transparent film relative to the lens in the width direction.

Abstract: An assembly of a glasses frame and two legs provides a tool-free, self-assembly and most secured frame-leg attachment contributed by a three-dimensional frame-leg contact structure, which is created by a mortise-tenon contact plane, as well as a protruding piece embedded therein. The mortise-tenon contact plane is formed by a frame tenon extending from the side of a frame, and flexibly received in a corresponding leg mortise on the upper end of the leg. The frame tenon is further refined into two planes of different sizes to enhance the stability of frame-leg attachment.

Abstract: A nose pad assembly applicable to all types of eyeglasses is provided, which includes an eyeglasses mainframe, and a nose pad structure. The eyeglasses mainframe includes in its center a nose rack with a trough sleeve on either end for accommodating the nose pad structure. The trough sleeve includes a hook-wall, a center groove, a peripheral groove, and an upholding opening with a smaller opening on the side facing outwards than on the side contacting the nose rack. The center groove joins the peripheral groove at the delimiting edge. The nose pad structure includes a nose pad mainframe flanked on each side with an insertion base, which connects an insertion piece. Each insertion piece includes an insertion wedge and an insertion pillar with a protruding rim for firmly secured inside the trough sleeve against the delimiting edge.

Abstract: A pair of eyeglasses with a unitary appearance by having the connecting piece concealed includes three parts: a lens-seat, two connecting pieces, and two temple assemblies. The unique alignment of the three parts in assembly allows for variegated design in the temple assembly, which can also be a restraining buckle strap. The adjustable temple assemblies can be easily assembled with the lens-seat without tools, which is rotatable relative to the lens-seat via different positions in meshing between the parallel teeth of the retaining piece (extending outwards from the temple assembly), and the protruding teeth of the connecting piece, thereby permitting an optimal adjustment of an inclination angle of the temple assembly.

Abstract: A flashlight with changeable filter structure comprising a cylindrical inner casing and a cylindrical filter base slides into the inner casing. The filter base comprises a female clasp and multiple hinge sets. On the exterior on the filter base, there are ribs and a gap. Multiple filter covers are provided and each filter cover comprises a cover and a filter. The cover is used to fix the filter. There is a hinge set on the filter cover. The hinge set is used to hook onto the hinge set of the filter base. In doing so, there are multiple filters available to meet different situation. Therefore, the operation is easier and more convenient, and saves the trouble of carrying many individual filters.
