Abstract: The present disclosure provides an optical element driving mechanism, which includes a movable part, a fixed assembly, and a driving assembly. The movable part is configured to be connected to an optical element. The movable part is movable relative to the fixed assembly. The driving assembly is configured to drive the movable part to move relative to the fixed assembly. The movable part includes a connecting assembly configured to position the optical element.

Abstract: An optical element driving mechanism is provided in the present disclosure. The optical element driving mechanism includes a fixed portion and a movable portion. The movable portion moves relative to the fixed portion. The movable portion includes a first movable assembly and a second movable assembly. The first movable assembly is connected to a first optical element. The second movable assembly is connected to a second optical element. The first movable assembly and the second movable assembly are movable relative to each other.

Abstract: An optical element driving mechanism includes a movable assembly, a fixed assembly, and a driving assembly. The movable assembly is configured to be connected to an optical element. The movable assembly is movable relative to the fixed assembly. The driving assembly is configured to drive the movable assembly to move relative to the fixed assembly in a range of motion. The optical element driving mechanism further includes a positioning assembly configured to position the movable assembly at a predetermined position relative to the fixed assembly when the driving assembly is not operating.

Abstract: An optical system for receiving rays of light is provided in the present disclosure, including a first optical module. The first optical module includes a first optical element and a first optical path-adjusting element. The first optical element has a first optical axis. The rays of light pass through the first optical element in a first direction. The first optical path-adjusting element corresponds to the first optical element. The rays of light are redirected to a second direction by the first optical path-adjusting element. The first optical element and the first optical path-adjusting element are arranged along the first optical axis.

Abstract: A luggage identifier, which is disposed on a luggage case or a luggage bag, includes a chassis and an identifying device, wherein the chassis includes a retaining space. The identifying device is disposed in the retaining space. The identifying device includes an identifying unit and a circuit board. The identifying unit is connected to the circuit board with a power switch connected therebetween. Accordingly, the user can easily and quickly identify his/her luggage case by recognizing the identifying device, thereby saving time on looking for the luggage case, and preventing himself/herself from claiming a luggage of other people.

Abstract: A golf practice device includes: a supporting base, a golf ball secured on a linking arm having a sleeve pivotally mounted on a shaft erected on the base, two rotor magnets having opposite outer magnetic poles and diametrically secured on two opposite ends of the sleeve, two stator magnets having opposite inner magnetic poles and secured on two opposite ends of a housing for surrounding the two rotor magnets for a mutual attraction between each stator magnet and each rotor magnet, a power generator having an iron core wound with coil windings on the core and surrounding the two rotor magnets for generating power due to change of magnetic field when rotating the sleeve and the two rotor magnets with respect to the iron core as driven by a hitting on the golf ball, and a display device for converting the power to an optical and audio signal for a visual and audio display for indicating the striking strength as hit by the golf player, and upon magnetic attraction between each stator magnet and each rotor magnet,

Abstract: A golf practice includes: a pivoting base fixed on a mat or a grass yard, a golf ball secured on a linking arm having a sleeve pivotally mounted on a shaft vertically erected on the pivoting base, two rotor magnets having opposite outer magnetic poles and diametrically secured on two opposite ends of the sleeve, and two stator magnets having opposite inner magnetic poles and respectively secured on two opposite ends of a hanging bracket fixed on a top portion of the shaft, with the two stator magnets diametrically aligned with the two rotor magnets fixed on the sleeve rotatably mounted on the shaft, each rotor magnet approximating each stator magnet by a rotation gap defined between the rotor magnet and the stator magnet, each rotor magnet having an outer magnetic pole facing an inner magnetic pole of each stator magnet with the outer magnetic pole of the rotor magnet having a polarity opposite to a polarity of the inner magnetic pole of the stator magnet for a mutual attraction between each rotor magnet and
