Abstract: A method for forming semiconductor devices includes providing a substrate with a conductive pad formed thereon; forming a transparent structure over the substrate, wherein the transparent structure includes a plurality of collimating pillars adjacent to the conductive pad; forming a light-shielding structure over the plurality of collimating pillars and the conductive pad; performing a cutting process to remove one or more materials directly above the conductive pad, while leaving remaining material to cover the conductive pad, wherein the material includes a portion of the light-shielding structure; and performing an etching process to remove the remaining material to expose the conductive pad.

Abstract: A depth generation system with adjustable light intensity includes at least one light source, at least one image capturer, a depth map generator, and a controller. Each light source of the at least one light source is used for generating emitted light. Each image capturer of the at least one image capturer is used for capturing an image including at least one reflected light generated by at least one object reflecting the emitted light. The depth map generator is coupled to the each image capturer for generating a corresponding depth map according to the image or the at least one reflected light. The controller is coupled to the depth map generator for determining whether to adjust intensity of the emitted light according to information of the corresponding depth map or intensity of the at least one reflected light.

Abstract: A retractable safety syringe comprises a needle body, a syringe barrel, and a pusher plunger. The needle body has a needle and a needle seat having an upper needle seat and a lower needle seat; the upper needle seat is used for fixing the needle thereon and is provided with a connecting portion on the bottom; and the removable lower needle seat can be embedded to the upper needle seat from below. The pusher plunger has a piston in the front end thereof; the piston has a connecting member, which can connect to the connecting portion on the bottom of the upper needle seat, so that after injection, by applying a force to press and deform the piston till connecting to the connecting portion, the needle body can depart from the needle socket and the abutment and can be drawn back to the interior of the syringe barrel.

Abstract: A disposable safety self-destroyed syringe comprises a plunger and a syringe tube. An end of the plunger is sleeved with a piston, and an elastic protrusive column is coupled inside the piston with its front end being protruded to a distance from a top surface of the piston; the plunger is inserted into the syringe tube from its front end for injection, and the rear end of the syringe tube is contracted radially to form a needle seat having a blocking portion on the inner wall to be conjoined with a needle, so that when the plunger is depressed to reach closely to the rear end of the syringe tube, a front end of the protrusive column is inserted into the needle seat and is stopped by the blocking portion on the inner wall of the needle seat to retain the protrusive column inside the needle seat.

Abstract: A differential device includes a drive gear, which has a gear wheel with a center axle hole and multiple needle rollers radially mounted in the gear wheel, a first coupling device, which has an abutment wall abutted against the needle rollers at one side and a stub axle inserted through the center axle hole of the gear wheel and a coupling tube for coupling to a first external wheel, and a second coupling device, which has an abutment wall abutted against the needle rollers at an opposite side and rotatably coupled to the stub axle of the first coupling device and a coupling tube for coupling to a second external wheel.

Abstract: A back-light module includes a light-guiding plate and a light source. The light-guiding plate has a lateral inlet surface. The light source is arranged at one side of the lateral inlet surface. The light source has a plurality of light-emitting diodes which are disposed in a line and at interval. A gap is formed between the adjacent light-emitting diodes. The lateral inlet surface dispose a plurality of convex lenses, each of the convex lenses has a convex surface facing to the corresponding gap between the adjacent light-emitting diodes.

Abstract: A double-side scanning device includes glass platforms having an upper glass platform and a lower glass platform separated apart form each other to define a sheet-passage. Each of the glass platforms is divided into a scanning area and a light penetrating area. Light sources include a first light source disposed beneath the scanning area of the lower glass platform and a second light source disposed above the scanning area of the upper glass platform. Reflectors include first reflectors arranged beneath the lower glass platform and second reflectors arranged above the upper glass platform. A prism mounted at a side of the light penetrating areas of the glass platforms has at least two reflex surfaces for respectively receiving the image incident light from the first reflectors and the second reflectors. A lens is mounted at back of the prism. And an image-gathering device is disposed at back of the lens.
