Abstract: An optoelectronic device includes a first substrate, a second substrate, a photonic integrated circuit, and a laser diode. The second substrate is over the first substrate. The photonic integrated circuit is disposed on the first substrate and includes a first waveguide channel, a second waveguide channel, and a patterned structure. The first waveguide channel and the second waveguide channel are coupled to the patterned structure. The laser diode is disposed on the second substrate and configured to emit a light beam toward the patterned structure.

Abstract: A power system includes a power conversion circuit, a DC converter and an inverter. The power conversion circuit is coupled to a AC supply line and a DC supply line to convert voltage between the AC supply line and the DC supply line. The DC converter is coupled to the DC supply line and a charging device. The inverter is coupled to the AC supply line and the charging device. When the charging device provides a supply power to the inverter, the inverter is configured to convert the supply power into a recovered power and transmit the recovered power to the power conversion circuit.

Abstract: Systems, methods, circuits, and devices for managing data transfers in semiconductor devices are provided. In one aspect, an integrated circuit includes: a first interface for receiving higher-speed-type data, a second interface for receiving lower-speed-type data, a first logic circuit coupled to the first interface, a second logic circuit coupled to the second interface, and a driving circuit separately coupled to the first logic circuit and the second logic circuit. The first data interface, the first logic circuit, and the driving circuit are arranged in series to form a first data path for transferring the higher-speed-type data with a first speed. The second data interface, the second logic circuit, and the driving circuit are arranged in series to form a second data path for transferring the lower-speed-type data with a second speed. The first speed is higher the second speed.

Abstract: An intelligent transparent light-shielding system applied to a vehicle includes a camera, a transparent display, and a processor. The processor converts an original driving image received from the camera into a grayscale image, converts the grayscale image into an anti-glare image according to a preset threshold, and transmits the anti-glare image to the transparent display for display. Pixels in the grayscale image with grayscale values equal to or lower than the preset threshold respectively correspond to pixels in the anti-glare image with grayscale values equal to a lower limit value. Pixels in the grayscale image with grayscale values greater than the preset threshold respectively correspond to pixels in the anti-glare image with grayscale values greater than the preset threshold. A light-shielding rate of the transparent display corresponds to the grayscale values of the pixels in the anti-glare image.

Abstract: A vehicle decorative plate and a forming method thereof are disclosed. The vehicle decorative plate can be made into a vehicle emblem, a vehicle grille, a vehicle front bumper trim, a vehicle door trim or a vehicle rear bumper trim. The vehicle decorative plate includes a curved substrate, a display layer, and a curved covering. After the curved substrate is coated with a plating layer, unnecessary parts of the plating layer are removed by laser engraving to process the plating layer into the display layer. The curved covering is attached to the curved substrate and covers the display layer. At least one of the curved substrate and the curved covering is transparent or semi-transparent.

Abstract: A portable computer includes a host body and a cover. In this case, the host body has a containing space and at least one electronic component. The electronic component is disposed in the containing space, and the bottom of the host body is formed with an opening to expose the electronic component. The cover is removable from the host body. The cover is disposed on the host body to cover the containing space.

Abstract: A touch pad module of a computer has a metal click plate to control its operation system. A plastic member is attached under the metal click plate to provide a suitable and comfortable click action. The plastic has a frame portion and two button portions. Two button portions are respectively connected with the frame portion by a rib and a suspension arm. The suspension has an U-shaped spring to provide a proper elastic force when it is bent by a click action.

Abstract: A portable electronic device includes a housing, an aroma unit and a heat source. In this case, the housing has an accommodating part. The aroma unit is placed in the accommodating part. The heat source is adjacent to the aroma unit. The heat source provides thermal energy and the aroma unit receives the thermal energy and spreads an aroma.

Abstract: An electronic apparatus including a casing, at least a transparent illumination portion, a display and a light guide is provided. The transparent illumination portion is disposed on a surface of the casing while the display is for providing the transparent illumination portion with necessary light. The light guide for projecting the light provided by the display onto the transparent illumination portion has a light receiving end and a light outputting end, wherein the light receiving end is close to the display while the light outputting end is close to the transparent illumination portion.
