摘要： A solar energy utilization device (1000), solar light emitted from a transparent liquid (200) to a light receiver (120) in the apparatus (1000) forming total reflection; in addition, a light energy utilization portion (310) is laid above the bottom wall (112) of a light concentrating tank (110), better facilitating the concentration of solar light on the light energy utilization portion (310) by a liquid light concentrating apparatus (100), thereby preventing the solar light from being refracted from the light receiver (120) after being reflected by the light concentrating tank (110) into the transparent liquid (200), concentrating more solar light on the light energy utilization portion (310) of the light energy utilization apparatus (300), and increasing the light concentrating efficiency.

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： 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.

A double-sided photovoltaic panel is used and is arranged above a reflection surface along a sunlight incident direction, and thus on one hand, a back surface of the photovoltaic panel can absorb sunlight converged via a convergence system, and on the other hand, a front surface thereof can also absorb directly radiated sunlight, such that in the same spatial size, the capacity of a photovoltaic panel for absorbing and utilizing solar energy is effectively improved.

摘要： Color filter patterns are invented for coating an array of imaging sensing elements so to obtain color images. Each of the color filter patterns consists of a luminance color Y and two other complementary or non-overlapping colors tessellated in a Bayer pattern, hexagonal pattern, YUV422 pattern, or other ordered tessellation. In two preferred embodiments of the invention, the color filter pattern differs from a conventional Bayer Pattern or a conventional hexagonal RGB pattern only in that the G color is replaced by a luminance color Y. The color filter for luminance Y can be realized by a transparent coating or no coating at all. In addition, the effective sensing areas of different colors are so chosen that desired signal-to-noise ratios are obtained by adjusting the color sensing areas and/or the sizes/curvatures of the micro lenses for the color pixels.

摘要： Disclosed is a light-concentrating solar device, comprising two nested reflection-type light-concentrating troughs, and a double-sided light energy utilization device. The direction of a top opening of the second light-concentrating trough is consistent with the direction of a top opening of the first light-concentrating trough, and the bottom of the second light-concentrating trough is located inside the first light-concentrating trough. The double-sided light energy utilization device is arranged at the bottom of the second light-concentrating trough, and both the front and back sides of the double-sided light energy utilization device can receive sunlight, with one of the sides facing the top of the second light-concentrating trough, and the other side facing the bottom of the first light-concentrating trough. The above structure can achieve a higher light-concentrating efficiency.
