Abstract:
A system for classifying tiny insects includes a cultivation tank, a detecting container, a detector, a gathering device, and a control unit. The cultivation tank is connected to the detecting container, so that the hatched tiny insects can enter the detecting area of the detecting container from the cultivation tank. The detector is used for detecting the characteristics of the tiny insects in the detecting area, and then the control unit controls the switching unit of the gathering device to switch the gathering containers for gathering the tiny insects according to the detecting results. The system of the present invention is capable of automatically classifying the tiny insects and then gathering them to different gathering containers according to their characteristics, so as to decrease the man power and time necessary for factitious classification.
Abstract:
A fabric printing method includes the following steps. A flexile underlayer and a fabric are provided and the fabric is pasted onto the flexile underlayer. The flexile underlayer and the fabric are sent to the printer to perform a UV printing. Thereby, the UV ink printed on the fabric can be suddenly dried to prevent the UV ink from expanding. Therefore, the figures on the printed fabric can be more delicate, beautiful and clear. The printed fabric can be mass produced by machine to reduce the cost and the manufacturing time. A printed fabric is also provided.
Abstract:
A handheld electronic device and an operating method thereof are provided. The handheld electronic device includes a first body, a second body, and a moving assembly. The moving assembly includes a sliding module and at least one rotating module. The sliding module is coupled to the second body, wherein the second body is moveable between a first position and a second position. The rotating module is coupled between the first body and the sliding module so that the second body is rotated relative to the first body. The second body is automatically rotated from the second position to a third position to form a first angle with the first body. The second body can be rotated between the third position and a fourth position to form a second angle with the first body, wherein the second angle is greater than the first angle.
Abstract:
A TV encoder with a function of adjusting hue for receiving a first and second color mixture signals comprises a first and second multiplexors, a sin-cos generator, a first and second multiplier circuits, and an adder circuits. The first multiplexor alternately outputs the second color mixture signal and its inverted signal. The second multiplexor alternately outputs a first angle signal representative of an angle and a second angle signal representative of the negative value of the angle. The angle is adopted to change the hue. The sin-cos generator outputs a sin and cos signals with a phase angle alternately determined by the angle and its negative value. The first color mixture signal and the sin signal are multiplied through the first multiplier circuit so as to be output as a first product signal. The second color mixture signal and its inverted signal are alternately multiplied by the cos signal through the second multiplier circuit so as to output as a second product signal. Finally, the first and second product signals are added through the adder circuit.
Abstract:
An automobile suspension system includes a suspending hydraulic cylinder interposed between the automobile body and an automobile wheel, a tensing hydraulic cylinder attached to the automobile body, an absorbing hydraulic cylinder attached to the automobile body, a hydraulic piping system intercommunicating these hydraulic cylinders, and a processing system sensing road conditions and driving situations to independently adjust the height of the corners of the automobile body, so as to offer shock-absorbing and anti-sway effects.
Abstract:
An optical touch control system is disclosed. A reflector surrounds a monitor. At least one image detection module is adjacent to the monitor and includes an image sensor, a reflective mirror, and a light source. The image sensor is electrically connected to an image processor. The reflective mirror is disposed on the image sensor and inclines to the image sensor by a predetermined angle. The light source outputs light onto the monitor. The reflective mirror reflects the light reflected by the reflector to the image sensor, identifying a touch control operation.

Abstract:
A detecting platform for holding a tiny insect includes a main body forming a containing space, which passes through the main body and is surrounded by side walls of the main body. A first side wall and a second side wall of the side walls are opposite to each other, and the area of the second side wall is smaller than that of the first side wall. The main body forms a first opening and a second opening passing through the first side wall and the second side wall respectively for the tiny insects entering and leaving the containing space. A bottom plate covers a first through surface of the containing space to form a bottom surface and a detecting area is configured thereon to holding the tiny insects. Accordingly, the tiny insects can stay on the detecting area so as to detect the characteristics of the tiny insects expediently.
Abstract:
A touch device to sense and compute the coordinate of a touch object is provided. The touch device comprises a panel, a light-emitting element, an image sensor, a reflective strip and a processing unit. The panel has a sensing area surrounded by first to fourth boundaries where the first and the third boundaries define an x direction and the other two boundaries defines y direction. The light-emitting element and the image sensor are located on the first boundary with a specific distance therebetween. The reflective strip is located on the second to fourth boundaries. When the touch object touches the sensing area, a first and a second light path from the light-emitting element to the image sensor are blocked to form a real and a virtual image such that the processing unit computes the coordinate of the touch object according to the real and the virtual images. A touch method is disclosed herein as well.
