Abstract: A laser ranger has a rotational light source and a receiver. The rotational light source is used to provide a light beam with a pre-determined rotation speed. The receiver detects the time period for the light beam to travel from a first position to a second position of the receiver, such that the distance between the rotational light source and the receiver is calculated based on the detected time period and the spacing between the first and second positions of the receiver.

Abstract: A method and structure for manufacturing long-wavelength visible light-emitting diode (LED) using the prestrained growth effect comprises the following steps: Growing a strained low-indium-content InGaN layer on the N-type GaN layer, and then growing a high-indium-content InGaN/GaN single- or multiple-quantum-well light-emitting structure on the low-indium-content InGaN layer to enhance the indium content of the high-indium quantum wells and hence to elongate the emission wavelength of the LED. The method of the invention can elongate emission wavelength of the LED by more than 50 nm (nanometer) such that an originally designated green LED can emit red light or orange light without influencing other electrical properties.

Abstract: A perfume spray head structure generally comprises a main body, a spray nozzle, a gas guide device, and a gas supply tube, wherein the spray nozzle, the gas guide device, and the gas supply tube are pre-assembled together and then coupled with the main body. By the use of the pre-assembled structure, the assembly process can be performed conveniently and the occurrence of displacement can be avoided. In addition, the spray head has gaps formed thereon for passage of gas and perfume liquid. The perfume liquid is sprayed out via the gaps so as to form uniform perfume mists. The perfume spray head structure of the present invention can avoid the occurrence of non-uniform spray mists, which is caused by the displacement of the spray channel.
