Abstract: An optical fiber connector includes a connecting unit, an adapter unit, and an attenuation unit. The adapter unit includes an insertion seat connected removably to a main housing of the connecting unit, and two guide frame bodies located respectively at two opposite sides of the insertion seat in a transverse direction. The insertion seat has two insertion holes spaced apart in the transverse direction and extending in a front-rear direction. Each guide frame body extends in the front-rear direction away from the connecting unit. The attenuation unit includes two attenuation components, two rear ferrules, and two front ferrules. The attenuation components are arranged in the transverse direction and disposed within the main housing. The rear ferrules respectively extend rearwardly from rear ends of the attenuation components into the insertion holes. The front ferrules respectively extend forwardly from front ends of the attenuation components through and outwardly of the main housing.

Abstract: A semiconductor package is provided, which includes a first chip disposed over a first package substrate, a molding compound surrounding the first chip, a first thermal interface material disposed over the first chip and the molding compound, a heat spreader disposed over the thermal interface material, and a second thermal interface material disposed over the heat spreader. The first thermal interface material and the second thermal interface material have an identical width.

Abstract: A holographic projection operating device, holographic projection device and holographic optical module thereof are illustrated. The holographic optical module has a first and a second prism array. The first prism array has a plurality of first prisms with first faces in contact with each other to form a first optical interface. The second prism array has a plurality of second prisms with second faces in contact with each other to form a second optical interface. Light is incident on the first optical interface at a first incident angle to undergo total internal reflection and generate a first reflected ray or at a second incident angle to undergo total internal reflection and generate a second reflected ray. The first or second reflected ray enters the second prism array and hits the second optical interface at a third incident angle to undergo total internal reflection and generate a third reflected ray.

Abstract: A portable electronic device includes a first component, a second component, a pivoting device, a cover member and a linkage module. The second component is pivotally coupled to the first component through a pivoting device. The second component has an internal space and a sunken portion. The sunken portion is in communication with the internal space. The cover member is movably embedded in the sunken portion. The linkage module is coupled to the pivoting device and the cover member for selectively pushing the cover member out of the sunken portion with the movement of the pivoting device.

Abstract: A device base includes a chassis, a support frame, two shielding members, a crank and a connecting rod. The chassis has an elongated slit and a pivoting seat. The support frame is slidably disposed within the elongated slit between the shielding members, and pivotally connected to the pivoting seat. One of the shield members is fixed to the support frame. The connecting rod is pivotally connected to the crank and the other shielding member. The crank is fixed to the support frame. The elongated slit is completely shielded by the support frame and at least one of the first shielding member and the second shielding member, collectively.

Abstract: A head-mounted display includes a display device, a bonding structure connected to the display device, a driving element connected to the bonding structure, and a rotation button connected to the driving element. When the rotation button is rotated, the length of the bonding structure is changed by the driving element.

Abstract: A stage light includes a base, a housing pivoted on the base, a lighting module, an emitting lens, a dimming module, a light-convergent assembly, and a prism. The housing includes an accommodating chamber and an opening communicating with the accommodating chamber. The lighting module is disposed within the accommodating chamber and includes a heat-dissipating element, a lighting assembly, an optical lens, and a diffuser. The heat-dissipating element includes a heat-conductive block fixed on the housing and at least one heat pipe penetrating the heat-conductive block. The lighting assembly includes a circuit board fixed on the heat-conductive block and a plurality of LEDs with different colors mounted on the circuit board. The optical lens and the diffuser are disposed corresponding to the LEDs. The emitting lens covers the opening. The dimming module, the light-convergent assembly, and the prism are located between the lighting module and the emitting lens.

Abstract: A light guide plate includes a lateral side through which light enters and a front side through which light exits. A phosphor is coated on the lateral side. A light source includes a plurality of light emitting diodes (LEDs) having wavelengths of 230-520 nanometers (nm). The LEDs are mounted proximate to the lateral side and corresponding to, but separated from, the phosphor. A reflector includes a reflective surface and is mounted on a back side of the light guide plate with the reflective surface facing the light guide plate. A frame fixes the light guide plate, the light source, and the reflector. Colors of the phosphor and the light source are complementary. The phosphor absorbs light from the light source to transition into an excited state. The light guide plate outputs light from the light source and the phosphor through the front side.
