Abstract: A lens structure formed by materials in different refractive indexes includes a transparent sphere in a first refractive index as well as a transparent second lens in a second refractive index. The first refractive index is different from the second refractive index, and the sphere is a round ball formed by a first portion and a second portion which are equipped with a first light condensing effect. The first lens is formed on the first portion of the sphere, the second portion of the sphere is exposed out of the first lens, and the first lens is provided with a first light absorption curve opposite to the first portion of the sphere, so that a light beam can pass through the second portion of the sphere to form the first light condensing effect, and then pass through the first light absorption curve to form a second light condensing effect.

Abstract: A varifocal lens module, consisting of a casing provided with a holding chamber, an opening end, an interconnecting hole, a soft lens disposed on the casing to seal the holding chamber, and a medium control device connects to the interconnecting hole. The soft lens is provided with a first curved surface having a first curvature exposed external of the casing and a second curved surface having a second curvature positioned interior of the holding chamber corresponding to the first curved surface. The medium control device is connected to the interconnecting hole for controlling the volume of the medium inside the holding chamber, whereby the change in volume of the medium changes the compression on the second curved surface, thereby modifying the second curvature of the second curved surface, producing a variation in the spacing between the second curved surface and the first curved surface to achieve a varifocal effect.

Abstract: A lens structure formed by materials in different refractive indexes includes a sphere, a first lens and a separation layer which is disposed between the sphere and the first lens. The sphere and the first lens have a different refractive index and the sphere is a round ball. The first lens is formed on the sphere that part of the sphere is exposed out of the first lens, and the first lens includes a first light absorption curve. The separation layer includes a transparent section opposite to the first light absorption curve. When a light beam passes through the second portion of the sphere to form a first light condensing effect and enter the sphere, the light beam will then pass through the transparent section to enter the first lens, forming a second light condensing effect after passing through the first light absorption curve.

Abstract: The present invention discloses a Fresnel lens with better reflection area and refraction area. The Fresnel lens includes a converging surface and an incidence surface opposite to the converging surface. The incidence surface is provided with an optically effective refractive region and an optically reflective region annularly surrounding the optically effective refractive region. The optically reflective region is provided with a first prism annularly disposed outside the optically effective refractive region and a second prism annularly disposed outside the first prism. The first prism and the second prism are arranged concentrically. A first lead angle portion is formed between the first prism and the second prism, and the radius of the first lead angle portion is between 0.01 mm and 0.019 mm to increase the effective working area of the first reflection surface and the second refraction surface.

Abstract: The present invention discloses a Fresnel lens with a light receiving effect, including a converging surface and an incidence surface opposite to the converging surface. The incidence surface is provided with an optically effective refractive region and an optically reflective region annularly surrounding the optically effective refractive region. The optically reflective region is provided at least with a prism annularly disposed outside the optically effective refractive region. The prism is provided with a refraction surface which is in adjacent to the optically effective refractive region and a reflection surface which is disposed at a first angle relative to the refraction surface. In addition, a tail end of the prism is an inverted hook part. Therefore, the effective working area of the refraction surface and the reflection surface can be increased, thereby improving the light receiving effect of the Fresnel lens.

Abstract: A reaction device for a tiny organism includes a chamber, a first support plate, a second support plate and a separation plate. The tiny organism and a culture medium are added in the chamber. The first support plate is disposed on an opening of the chamber. The second support plate is disposed on one side opposite to the side on which the first support plate is disposed, and a third hole and a fourth hole separately correspond to a first hole and a second hole of the first support plate. A first end of the separation plate is located inside the chamber, the first end of the separation plate is spaced from the bottom of the chamber by a predetermined distance, a second end of the separation plate passes through the first support plate to connect to the second support plate.

Abstract: An in-car temperature-controlling device for a car in its parked state uses a wireless remote control to remotely control a power-activating unit, an engine-starting unit, a window-activating unit and an AC-activating unit of the car, so as to adjust the car's in-car temperature. Its installation is easy and needs no structural changes to the car, so the car using the device can, in its parked state, have its in-car temperature prevented from being too high or too low. The in-car temperature-controlling device is characterized in contributing to convenience, safety, comfort and low costs, and is applicable to all existing and newly built cars.

Abstract: A CMOS image sensor includes a semiconductor substrate, a plurality of pixel regions in the semiconductor substrate, a deep trench disposed between two adjacent pixel regions and filled with a polysilicon layer doped a first conductivity type, a plurality of well regions having a second conductivity type in each of the pixel regions, a through hole connected to the polysilicon material, and an metal interconnect layer connected to the through hole. The deep trench filled with the doped polysilicon layer completely isolates adjacent pixel regions. A voltage applied to the metal interconnect layer extracts excess photoelectrons generated by intensive incident light to improve the performance of the CMOS image sensor.

Abstract: A method of performing video stabilization may be applied to unstable frames captured by a vibrating camera. The method includes checking if the frame is vibrating and calculating a degree of vibration for compensating a vibration area. Based on block motion estimation, a feature block selected from nine fixed observation blocks is used to obtain a vibration vector. The vibration vector is used to adjust the vibration frame for restoring the frame.
