Abstract: A transparent film is used with a projector which emits a projected light. The transparent film includes a transparent substrate; a light-scattering layer disposed at an upstream position of the transparent substrate with respect to the projected light, and including a plurality of microstructures configured to scatter the projected light; and a light-blocking layer disposed at an upstream position of the light-scattering layer with respect to the projected light, and including a plurality of separate light-blocking units, which are configured to partially block the projected light and partially allow the projected light to reach the light-scattering layer.

Abstract: An embodiment includes a first lead guide, a second lead guide, and a handler. The first lead guide includes a first insulating housing and a first conductive contact having a face and a recessed face. The second lead guide includes a second insulating housing and a second conductive contact. The first and second lead guides are fastened to the handler.

Abstract: A striker includes a base portion, a striking portion, and two reinforcing ribs. The base portion has opposite slide surface and base surface, and a front end surface connected between the slide and base surfaces. The striking portion is formed on the front end surface, and has a maximum width in a direction perpendicular to a longitudinal axis smaller than a width of the front end surface. The reinforcing ribs are connected to the base portion. Each reinforcing rib has first and second edges disposed respectively distal from and proximate to the base surface in a direction perpendicular to the longitudinal axis, and disposed respectively distal from and proximate to the striking portion in a direction parallel to the longitudinal axis.
