Abstract: A movable dust collection device includes a processing table, a processing machine, and a collection unit. By the movable suction box, the dust, small parts and debris under the processing gun can be directly sucked and collected. The control unit controls the motor to drive the driving wheels to move the suction box beyond the processing table, which facilitates the cleaning of the small parts and debris, and improves the shortcoming of lifting the entire collection board for cleaning in the prior art.

Abstract: A current mode buck-boost converter has an input terminal, an output terminal, and an output capacitor coupled to the output terminal. The input terminal is used to receive an input voltage, and the output terminal is for producing the output voltage. The current mode buck-boost converter comprises a voltage converter and a control circuit. The voltage converter comprises an inductor. The control circuit is for detecting the current passing through the inductor to determine the electric energy transmitted to the output terminal by the voltage converter. Accordingly, the current mode buck-boost converter has fast response, and the electrical energy can be recycled and stored to the voltage source when the current mode buck-boost converter operates in down-tracking process.

Abstract: A battery management circuit, a battery module and a battery management method are provided. The battery management circuit includes a conduction circuit and a control circuit. The battery management is coupled to a rechargeable battery cell and has a first conduction path passing through the rechargeable battery cell and a second conduction path without passing through the rechargeable battery cell. The control circuit is coupled to the rechargeable battery cell and the conduction circuit, and conducts selectively the first conduction path or the second conduction path of the conduction circuit so as to avoid over charging or over discharging of the rechargeable battery cell.

Abstract: A structural and functional model for a lung or similar organ is virtually defined by encoding aspects of branching passageways. Larger passageways that are visible in medical images are surface mesh fitted to the anatomical surface geometry. Smaller distal passageways, beyond a given number of branch generations, are modeled by inference as linear passages with nominal diameters and branching characteristics, virtually filling the space within the outer envelope of the organ. The model encodes finite volumetric elements for elasticity and compliance in passageway walls, and for local pressure and flow conditions in passageway lumens during respiration. The modeling can assess organ performance, help to plan surgery or therapy, determine likely particle deposition, assess respiratory pharmaceutical dosing, and otherwise represent structural and functional organ parameters.

Abstract: The present invention provides a voltage shifter circuit, in which a control circuit is used to control the pull-up circuit, so that the pull-up circuit is kept as off when the signal from the input signal source changes from a low voltage to a high voltage. Hence, the competition between the pull-up circuit and the pull-down circuit is avoided. The speed of the voltage shifter circuit is improved and the voltage shifter circuit can operate within a wider voltage range. The delay time of the pull-up circuit and the pull-down circuit is small and the duty cycle is small. In addition, since no direct current path is established, no current is wasted. Additionally, the voltage shifter circuit uses the second delayer to compensate the delay time between the pull-up circuit and the pull-down circuit and optimizes the duty cycle.

Abstract: A novel apparatus and method for calibrating the gap distance between adjacent scrubber brushes with the frictional force of the brushes against a wafer, is disclosed. The apparatus includes a support frame, at least one pair of load cells carried by the support frame, at least one test plate operably engaging the load cells, and at least one electronic indicator operably connected to the load cells, respectively, for indicating a force exerted on the load cells by the test plate. The method includes placing at least one test plate between the adjacent scrubber brushes, rotating the scrubber brushes against the test plate, determining the frictional force of each brush against the plate, and adjusting the gap distance between the brushes to obtain a desired frictional force for the scrubber cleaning of production wafers.
