A coordinate measuring apparatus for measuring a workpiece having a workpiece surface includes a sensor to capture the workpiece surface and a mechanism to move the sensor in coordinate directions (x, y, z) relative to the workpiece. The mechanism includes a rigid frame, a mount and measuring skids. The rigid frame includes mutually parallel horizontal longitudinal members having respective horizontal guides. The rigid frame includes vertical supports having respective upper and lower ends. The horizontal longitudinal members are rigidly connected to the upper ends of the vertical supports. The rigid frame includes transverse members oriented transverse to the longitudinal members and being rigidly connected to the lower end of the vertical supports. The transverse members are supported via the mount and a first one of the measuring skids is configured to move the sensor in the coordinate direction (x) along the first and second horizontal guides.

A horizontal synchronization signal detection system includes a coarse period estimator and a fine period time estimator. The coarse period estimator estimates a minimum value and corresponding position of each period of a CVBS signal to calculate a coarse period of a horizontal synchronization signal. The fine period time estimator divides the horizontal synchronization signal into a first part and a second part so as to generate a first sum and a second sum by adding signals of the first part and the second part, and detects a middle point of the horizontal synchronization signal when the first sum equals the second sum. The steps of fine-tuning the coarse period to generate a fine-tuned coarse period, extracting the horizontal synchronization signal according to the fine-tuned coarse period, and determining whether the first sum is equal to the second sum are repeatedly executed until the first sum equals the second sum.

The invention relates to an all-in-one machine for vacuum forming, molding and punching, comprising a rack, a material traction device, a heating device, a forming unit, a punching device and a control device; wherein a top die platform and a bottom die platform of the forming device are provided with moulding moulds which are thereupon provided with a convex part or a concave part for forming a light trapping bump on plastic sheets; the punching device comprises a punching shear mechanism, a guide rail which moves frontwards and backwards and a photocell eye for detecting the light trapping bump; the guide rail is arranged in the front of the punching shear mechanism, the photocell eye is arranged in the front of the punching shear mechanism and is connected with a corresponding input terminal corresponding to the control device.In the invention, when forming is carried out, the light trap bump can be formed on the plastic sheet, the flaky plastic products can be prevented from transversely displacing by the guide of the guide rail, the photocell eye can be used to detect the light trap bump and the control device can be used to lead the material traction device to convey the flaky plastic products to preset distance, so that the longitudinal position of the plastic products is accurate when the plastic products enter the punching shear mechanism and the flaky plastic products can accurately arrive at the preset position of the punching mechanism.

The invention discloses a cerebral cistern contrast medium injection device, which comprises a left and right moving mechanism, a lifting mechanism and an injection mechanism. The horizontal movement of the left and right moving mechanism enables the entire operating table to be adjusted in the horizontal direction through the cooperative movement of the worm gear. The lifting mechanism realizes the adjustment of the position of the console in the vertical direction through the cooperative movement of two sets of bevel gears and the rack and pinion. The injection mechanism injects the to-be-injected agent into the human body through the swing of the link mechanism and the sliding of the slider mechanism, and completes the human body injection of the contrast medium in the brain cisterns.

A sectional folding overhead door assembly that includes a pair of opposite, vertically disposed side supports and guides defining a door opening between them, each of the supports and guides including a first channel and a second channel disposed side-by-side, a door component having a first, second, third and fourth rectangular panel adapted for folding vertical movement along the supports and guides, a folding movement controlling member, each folding movement controlling member having a folding movement controlling member upper end hingeably connected to a respective side edge of the first and third panels, respectively, and a folding movement controlling member lower end hingeably connected to the respective guide plate lower end around a folding movement controlling member hinge axis, and a folding movement guiding channel into which a respective side plate guiding pin of a side plate attached to the second panel extends.
