    摘要： A heat dissipation device includes a base and a fastener. The fastener includes a neck portion, a head portion formed at one end of the neck portion, and an engaging portion formed at another opposite end of the neck portion. The base defines a receiving portion through the base. The receiving portion includes an inserting hole and a mounting hole communicating with the inserting hole. A flange extends upwardly from the base toward the mounting hole. The engaging portion extends through the inserting hole from a top of the base to make the neck portion enter the inserting hole. The neck portion is then crushed into the mounting hole from the inserting hole. A top face of the head portion abuts the flange, a bottom face of the head portion abuts the base.

    摘要： A laser marker/pointer for projecting size-adjustable circular or elliptical laser beam patterns onto a target surface such as a portion of a presentation screen or to assist in the aiming of a firearm, comprises a handheld shell body in which is mounted a laser light source, a rotating wedge prism driven by an electric motor through a belt pulley or a gear system, two convex lenses, a DC power unit, and a mechanical and electric control unit. The rotating wedge prism is placed between the two convex lenses to refract the laser beam into an opening-angle adjustable hollow light cone. The projection of the hollow light cone onto a target surface generates circular or elliptical tracing patterns. The mechanical and electric control unit controls the laser pattern generation and its size adjustment through driving the wedge prism rotation around the emitted laser beam direction and its linear movement along the beam direction. The position of the wedge prism along the original emitted laser direction determines the size of the circular or elliptical pattern. A push button switch controlling the power on and off of the device can be slid in two directions to either enlarge or reduce the size of the generated pattern.

    摘要： A laser marker/pointer for projecting circular or elliptical laser beam patterns onto a target surface such as a portion of a presentation screen or to assist in the aiming of a firearm, comprises a handheld shell body in which is mounted a laser light source, a rotating optical mirror driven by a motor, and an electronic drive circuit, whereby the aspect ratio of the marking pattern is determined by the geometric relationship of the motor shaft axis, the laser beam, and the mirror surface. The motor drive circuit when initially powered (along with the laser diode), applies full power (a continuous DC voltage to the motor to overcome inertia), followed by a pulsed voltage to lower the duty cycle of the motor, increase battery life, and reduce rotational noise.
