Abstract: A laser beam scanning system includes a light source, a projection, a micro-mirror, a controller, and a light detection module. The light source generates a laser beam, and the micro-mirror deflects the laser beam to create a scan trajectory on the projection. The controller generates a control signal and a drive signal. The control signal turns the laser beam on and off, and the drive signal controls scan movements of the micro-mirror. The light detection module is placed at a margin of the projection. The light detection module includes a photo sensor underneath a light-blocking top layer having a slot to expose the photo sensor. The photo sensor generates a detection pulse in response to detection of the laser beam in one or more segments of the scan trajectory. The controller is operative to measure a detection pulse width in clock cycles.

Abstract: An antenna comprises a ground element, a first transmission element, a feed element, a second transmission element and a third transmission element. The first transmission element is electrically connected to the ground element, wherein the first transmission element comprises at least one coupling portion, a first side and a second side. The feed element corresponds to the coupling portion. The second transmission element corresponds to the first side and is electrically connected to the ground element. The third transmission element corresponds to the second side and is electrically connected to the ground element. When a first wireless signal is transmitted, the feed element couples to the first transmission element to transmit the first wireless signal. When a second wireless signal is transmitted, the feed element couples to the first transmission element, and the second and third transmission elements couple to the first transmission element to transmit the second wireless signal.

Abstract: A method for forming an array of zinc oxide nanowires on a substrate is disclosed, which includes forming a crystal phase adjusting buffer on the surface of the substrate and growing 1D zinc oxide nanowires on the buffer by zinc vapor deposition, which are normal to the surface of the substrate. The crystal phase adjusting buffer includes, for example, nitride and oxide layers on a silicon substrate, or a gallium nitride epitaxial layer on a sapphire substrate, and is used as a growth buffer layer for the zinc oxide nanowires. The zinc vapor phase deposition includes forming a zinc oxide layer on the crystal phase adjusting buffer and forming vertical zinc oxide nanowires on the zinc oxide layer.

Abstract: The specification discloses a material with a surface nanometer functional structure and the method of manufacturing the same. Using the properties of supercritical fluids, a nanometer structure is formed on the surface of a substrate, resulting in a material with a surface nanometer functional structure. The supercritical fluid carries the precursor of functional materials. Once they reach a reaction balance with the substrate in a high-pressure container, the pressure is released at an appropriate speed. The carbon dioxide supercritical fluid undergoes a vaporization reaction, distributing and adhering the precursors on the substrate to form the surface nanometer functional structure. Utilizing the VLS nanowire growth method, one-dimensional and two-dimensional compound nanometer functional wire structure can be produced.
