Abstract: A soft collision grating scale and measuring method thereof comprises a fixed scale, a sliding auxiliary scale slidably disposed relative to the fixed scale, and a moving pin sliding relative to the sliding auxiliary scale. The moving pin and the sliding auxiliary scale move synchronically. A buffering mechanism is disposed on the moving pin. When the moving pin sliding relative to the sliding auxiliary scale cooperates with a buffering force of the buffering mechanism, a collision between the moving pin and stopping faces of an inspected target is automatically offset to attain a soft collision effect, which prevents the moving pin from breaking to keep an normal measurement operation and increases the precision of measurement by the fact that the sliding auxiliary scale does not rebound and an offset distance caused by reversely moving the moving pin relative to the sliding auxiliary scale can be computed.

Abstract: The present patent application discloses a digital slit-lamp microscope system and the methods of the electronic recording and remote diagnosis. The present patent application relates to the field of optical instrument and remote communication control. The purpose is to solve the problems of the electronic recording, reappearing and remote diagnosis of the slit-lamp image. The digital slit-lamp microscope system comprises digital slit-lamp microscope side, communication unit and client side. The digital slit-lamp microscope side includes a build-in slit-lamp microscope and is connected to the communication unit and the client side in sequence. The digital slit-lamp microscope side irradiates the eyes of the patient, and then transmits the pathology information of the eyes of the patient to the communication unit and the client side in sequence.

Abstract: An eye imaging system, including: a light source module; a radial splitting module; a common optical module; an image receiver; a power supply module for the light source module; a driver module for the image receiver; a processing-displaying module; and a motion driving module. The image receiver is an area array sensor. The motion driving module is connected to the light source module and drives the light source module to move in a radial direction of an upstream illuminating optical path formed by the light source module and the radial splitting module. The image receiver continually opens for exposure in a radial direction of a downstream observation optical path formed by the radial splitting module and the image receiver. The continual opening of the image receiver for signal acquisition is synchronous with the movement of the light source module.

Abstract: Disclosed is a folding sheet music stand that is capable of being folded into a very compact package. In the folded position, the folding sheet music stand is easily transportable and less susceptible to damage. A carrying bag can be used to transport the folded sheet music stand. The folding sheet music stand can be easily assembled and provides a sturdy platform for displaying folded sheet music to musicians. The folding sheet music stand is fully adjustable so that the folding sheet music stand can be used by musicians using various different types of instruments.

Abstract: Method and apparatus of controlling and positioning a fluid actuator by supplying pressurized fluid to right and left actuating chambers of the actuator through an on-off control valves. To drive and position the actuator rapidly and accurately, the actuator can be driven at a higher speed by an initial driving force until it reaches near the desired position and continuously moved at a low speed by gradually increasing the fluid pressure to be supplied to the right and left actuating chambers of the actuator. The initial driving force in the high-speed range becomes maximum when the pressure is applied to one of the right and left actuating chambers while at the same time the other actuating chamber is exhausted. In the low-speed range and near the target position, the one actuating chamber is continuously supplied with the pressure while at the same time the other actuating chamber is gradually closed.

Abstract: A hand-held pulverizer which is compact and efficient to use is provided to pulverize or grind a material. A cover is removably attached to a hollow cylindrical casing containing a mesh screen. A grinder disc is securely affixed to one end of a shaft rotatably mounted in the cover and is in frictional contact with the mesh screen. A handle attached to the shaft above the cover permits the shaft and disc to be rotated, grinding or pulverizing the material placed on the screen beneath the disc. A collecting plate attached to the bottom of the cylindrical casing receives the pulverized material falling through the screen.

Abstract: A non-photographic, digital laser image recording and reading method and apparatus for recording and reading visual, two-dimensional replicas or representations of objects, pictures, illustrations, computer outputs and the like. A flat-field twin objective is employed to project the image of a laser beam focused to a diffraction limited spot on a radiation sensitive material, e.g., a heat ablatable or vaporizable recording medium to create a two-dimensional ensemble of holes in the recording medium. The recording medium comprises thin metallic films carried on flat substrates which are moving at constant speed or are immovably held while the image of the diffraction limited spot is scanned thereover by angularly deflecting the laser beam entering the twin objective. The visual laser record is an instantaneous replica of an original image or its computer processed binary equivalent.
