Abstract: A light-emitting device, including a first type semiconductor layer, a patterned insulating layer, a light-emitting layer, and a second type semiconductor layer, is provided. The patterned insulating layer covers the first type semiconductor layer and has a plurality of insulating openings. The insulating openings are separated from each other. The light-emitting layer is located in the plurality of insulating openings and covers a portion of the first type semiconductor layer. The second type semiconductor layer is located on the light-emitting layer.

Abstract: A method employed by a circuit included within a receiver apparatus and configured for performing IQ mismatch compensation when receiver apparatus is operating under data reception mode includes: transforming a data signal, which is generated by a radio frequency receiver under the data reception mode, from time domain into a plurality of frequency bin signals in frequency domain; calculating to obtain at least one frequency domain calibration parameter according to the plurality of frequency bin signals in frequency domain; and, updating at least one coefficient parameter of IQ mismatch compensation according to the obtained at least one frequency domain calibration parameter, to make IQ mismatch compensation compensate IQ mismatch based on the updated at least one coefficient parameter.

Abstract: A collapsible garbage bag supporter includes two transverse pipes, four leg pipes, two elastic lines and two positioning members. Each transverse pipe has its two ends respectively connected to the upper end of the leg pipes. The elastic lines are inserted in the leg pipes, letting a transverse pipe and two leg pipes connected into an inverted-U shape. Every two leg pipes have their intermediate portion pivotally riveted to make them intersect with each other. Each leg pipe is composed of two pipes connected together by inserting. The two positioning members are fixed on the two transverse pipes for stretching them open. The garbage bag supporter can be stretched open for fitting a garbage bag thereon. To collapse the supporter, disconnect each leg pipe from the pipe coupler and separate the lower portion from the upper portion.

Abstract: A car awning includes a shade storing case set, a cloth shade, a stretch rod unit and two standing posts. The shade storing case set is composed of a case body, a position rod, two swingable arms and two suckers. The suckers are placed at one side of the top of a car by sucking on a car by sucking. The position rod is fixed in the case body, two swingable rods are pivotally connected with two ends of the position rod for fixing an upper end of the cloth shade, which is to be wound thereon. The cloth shade is stretched flat by the stretch rod unit. The standing poles have the upper end combined with the stretch rod unit, standing on the ground, supporting the stretch cloth shade and forming the car awning for use. The car awning can be put in a car after disassembled, convenient for use.
