Abstract: A three-dimensional (3D) scanning system includes a projector that generates an emitted light projected on an object, a reflected light being reflected from the object; a sensor that generates image data according to the reflected light; and a depth processor that generates depth data according to the image data and at least one modified factor representing corresponding deviation amount between the image data and an ideal image data due to a circle of confusion caused by the reflected light passing a lens of the sensor and then irradiating a sense plane of the sensor out of focus.

Abstract: Methods for forming dummy under-bump metallurgy structures and semiconductor devices formed by the same are disclosed. In an embodiment, a semiconductor device includes a first redistribution line and a second redistribution line over a semiconductor substrate; a first passivation layer over the first redistribution line and the second redistribution line; a second passivation layer over the first passivation layer; a first under-bump metallurgy (UBM) structure over the first redistribution line, the first UBM structure extending through the first passivation layer and the second passivation layer and being electrically coupled to the first redistribution line; and a second UBM structure over the second redistribution line, the second UBM structure extending through the second passivation layer, the second UBM structure being electrically isolated from the second redistribution line by the first passivation layer.

Abstract: A three-dimensional sensing system includes a plurality of scanners each emitting a light signal to a scene to be sensed and receiving a reflected light signal, according to which depth information is obtained. Only one scanner executes transmitting corresponding light signal and receiving corresponding reflected light signal at a time.

Abstract: A luminous umbrella includes a power source, a switch, an electric wire, light emission objects, connectors and light permeable rods adapted to the umbrella comprised of a handle, a shank, ribs, spreaders, and a canopy with the power source and the switch contained in the handle. The power source is connected to the electric wire via the switch. The electric wire is placed inside the shank and the ribs and connected to the light emission objects. Each of the ribs has a U-shaped profile with its U-shape opening side attached flush on the canopy for the canopy to conceal the electric wire put inside the rib. Another end of each of the light permeable rods is exposed out of the canopy.

Abstract: A baby chair structure comprises legs, a seat section, arm rests and a tray. The legs are formed by four sets of cross rods, each set of cross rods has one top end jointed together with another top end of a neighboring cross rod to connect with a block which has an upright rod extending therefrom forming a conical shaped frame. The rear end upright rods are connected to the rear ends of the arm rests and then inserted into two sacks at respective sides of a back support. The front end of each arm rest has a protrusion, and the inside of the protrusion is for the front upright rod to extend therethrough. The tray comprises a pair of grooves for receiving the protrusions of the arm rests, a pair of C-rings are formed on the respective ends adapted to buckle the arm rests, and a safety belt is inserted through a hook of the tray and secure the baby.

Abstract: A folding table is provided that includes four legs, a top and two side panels. Two lateral tubes are fixed to those legs and the top is comprised of multiple planks connected with ropes. Locking bolts are respectively provided in the vicinity of each end of each of the lateral tubes. A pin protrudes from below each end of two of the outermost planks of the top. A step is provided in each side panel, and a connection hole and a locking hole are each provided in the vicinity of each end of each step. The connection hole is provided to secure the side panel to the legs and the locking hole is provided to receive a corresponding pin from a respective outermost plank to lock the planks to the side panel, so that the ends of each plank of the top are all butted with the step of the side panels.

Abstract: A structure of arm of a folding chair, particularly for a director's chair or a Wassily chair, comprised of an abutment, an arm-rest, and an elevation seat operated in conjunction with leg, splat tube, and webbing of the canvas seat; within, said abutment is provided at the upper end of the front leg and connected to a spring catch while one corresponding bore is provided at the front section of the arm rest, a recess with a lid is provided in the arm rest, and the rear end of the arm rest is pivoted to the front end of the elevation seat, a sleeve inserted onto the splat tube is provided on the elevation seat, the rear of the elevation seat is fixed with the webbing and can rest on the abutment by the front section of the arm rest then the spring catch on the abutment can be fixed in position in the bore at the front section of the arm rest so to fix it onto the leg.

Abstract: A folding table comprises a foldable table surface and a support frame. The table surface is formed with six pieces of wood boards and four clamps. The wood boards, or strips, are coupled one to the other, and the table surface is formed with clamps. The foot support includes a connecting device, four upper legs, four lower legs, four angle connectors and two rods. Wherein, the connecting device is a frame with four parallel boards, each board is connected to an upper leg and a lower leg, respectively. Each upper leg is connected to an angle connector and every two angle connectors are secured to a rod, thus, the table surface is secured to the rods and assembled with the legs.

Abstract: A quadruped includes a base with four receiving holes, a supporting stick mounted on the base, and a quadripod detachably mounted to each receiving hole of the base.
