摘要： An input device, comprising at least one key position (110) and a control and readout circuit (120). Each key position (110) is provided with a light transmission window (111) and a photosensitive device (112) thereon, the light transmission window (111) being used for the incidence of an external light, and the photosensitive device (112) being provided on the light path behind the light transmission window (111), the status of the photosensitive device corresponding to the light intensity of the incident external light. The control and readout circuit (120) is used for resetting and scanning each photosensitive device (112), and outputting, according to the scanned status of each photosensitive device (112), a key signal indicating whether the corresponding light transmission window (111) is covered or not. The input device obtains input information by means of sensing the variation of the light intensity, instead of the traditional press input method, enabling, on one hand, a quicker reaction speed and on the other hand requiring no finger press, not only reducing the workload of the finger, but also decreasing the requirement for finger dexterity.

摘要： A voice coil motor and a corresponding focusing lens. A rotor assembly (22) is connected to a stator assembly (21) by means of an elastic connecting piece (23). A stator sleeve (211) is sleeved on a rotor sleeve (221). One of the stator sleeve (211) and the rotor sleeve (221) is a permanent magnetic material sleeve, and the other is a non-magnetic material sleeve. An assembly to which the non-magnetic material sleeve belongs also comprises a pre-magnetic element (222) and a drive coil (223). The premagnetic element (222) is made of a permanent magnetic or magnetized material, and is fixed relative to the non-magnetic material sleeve. The elastic connecting piece (23) is in a force balance state in a case without power because of pre-existing magnetic force between the pre-magnetic element (222) and the permanent magnetic material sleeve. Smaller electromagnetic force is required for driving the elastic connecting piece (23) to move, thereby reducing a drive current and power consumption.

摘要： Disclosed is a solar power station, comprising a first light-receiving device having a substantially planar first working surface, a second light-receiving device having a second working surface substantially perpendicular to the first working surface, and a first drive mechanism. The first and second working surfaces are configured so that sunlight (SS) strikes the first working surface after passing through the second working surface or passes through the first working surface and then strikes the second working surface. The second light-receiving device is fixed on the first drive mechanism. The first drive mechanism is used to drive the second working surface to move or rotate relative to the first working surface according to the movement of the sun.

摘要： A Fresnel lens system, comprising at least two tooth faces located on the same light path; each of the tooth faces comprises at least one Fresnel unit, each Fresnel unit being a Fresnel refraction surface formed by an original curved surface; at least one of the two tooth faces is a complex Fresnel refraction surface or a filled Fresnel refraction surface, or the two tooth faces are at a same physical interface and an element located thereon has a reflective back surface. The Fresnel lens system can adequately utilize the advantage of thinness of Fresnel lens, thus better adjusting the light path without a significant increase in the thickness of the system.

摘要： A surface solar system, comprising a condensing clad plate (p1), a photovoltaic plate (p2) and a supporting component (p3), wherein the condensing clad plate is formed by splicing condensing modules in accordance with pre-set patterns. Each of the condensing modules comprises a condensing lens and a base, the condensing lens comprising at least one tooth surface, one of adjacent surfaces of the condensing lens and the base is a reflecting surface, and the reflecting surface is provided below the tooth surface along an incident surface of sunlight. The supporting component supports the photovoltaic plate above the condensing clad plate and is substantially located at a condensing position of the condensing clad plate. Since the condensing clad plate is formed by splicing a plurality of reflective condensing modules, the solar system is easy to install on a large area, and the reflecting surfaces are located inside the condensing modules, thereby being unlikely to damage and having better durability.

摘要： Provided is a sun tracking solar system, comprising a light focusing device and a solar energy utilization device. The system further comprises a drive mechanism (130), or further comprises a light guide device (240) and a drive mechanism (230). The drive mechanism is configured to drive a light-receiving surface to move with the sun. The light-receiving surface receives sunlight after convergence thereof by the light focusing device, and the driven light-receiving surface may be a light-receiving surface of the light energy utilization device (120), and may further be a light-receiving surface of the light guide device (240) located between the light focusing device (210) and the light energy utilization device (220). Since the driven surface is the light-receiving surface after light convergence, an area of the driven surface is usually less than an area of an original light-receiving surface. This simplifies a structure of the drive mechanism, reduces difficulty in sun tracking, energy consumption, and costs, and expands the application scope of a sun tracking solar system, or enhances the production efficiency of a sun tracking solar system.

摘要： Disclosed are an electromagnetic induction device and a method for manufacturing the same. The device comprises a magnetic cover (110) and at least one set of coils (120). The magnetic cover (110) consists of two or more magnetic units (111), and a closed magnetic flux loop can be formed within each magnetic unit (111). The magnetic units (111) are joined together to form a substantially closed integrated body having at least one cavity (112) therein, and dividing surfaces between the magnetic units (111) are disposed substantially along the magnetic flux loop without interrupting the magnetic flux loop. The coils (120) are placed in the cavity (112) formed by the magnetic cover (110), electrodes of the coils (120) are led out of the magnetic cover (110), and the magnetic flux loop in the magnetic cover (110) is formed after energization of the coils (120). The electromagnetic induction device of the present invention can substantially close coils, preventing magnetic flux leakage to a maximum extent. Further, since dividing surfaces between magnetic units are disposed along a magnetic flux loop, no air gap is generated in the magnetic flux loop, thereby effectively decreasing magnetic resistance.

摘要： A zoom/focus apparatus and corresponding zoom lens assembly are provided. The zoom/focus apparatus may include a first focus lens barrel (101), a first zoom lens barrel (102), a first ultrasonic motor and a second ultrasonic motor which are disposed coaxially. The first focus lens barrel and the first zoom lens barrel are radially unmovable. The caliber of the first zoom lens barrel is larger than that of the first focus lens barrel. The two ultrasonic motors are used to drive the two lens barrels to move axially by the rotation of the rotors (103, 104), respectively. Because the zoom lens barrel which needs to be moved is disposed at outside of the focus lens barrel, by driving the lens barrels using the ultrasonic motors, the telescoping of the zoom lens barrel and the adjusting of the zoom position can be achieved simultaneously. Because the zoom lens barrel has larger caliber such that it is suitable for wide-angle lens and the lens assembly becomes gradually larger from inside to outside when the lens group is installed from rear to front, the installing is more convenient and smooth and the miniaturization of the lens assembly is facilitated.
