20090048814 | PYROTECHNIC SHOCK SIMULATION SYSTEM AMD METHOD - A system to simulate pyrotechnic shock may include a pulse or signal generator to generate a predetermined signal waveform. A signal conditioning device may be included to condition the predetermined signal waveform to produce a predetermined shock simulation for a shock test. The system may also include a power amplifier to amplify the conditioned predetermined signal waveform to a chosen amplitude to produce a selected level of shock. A shaker system produces the selected level of shock in response to an amplified signal waveform from the power amplifier. A shock measuring device measures a shock imparted to the test specimen, and an output device presents a result of the shock test on the test specimen. | 02-19-2009 |

20120037729 | Insertion Type Fluid Volume Meter and Control System - An insertion type fluid volume meter and control system comprises a non-ferrous pipe, an electromagnet device, a pair of electrodes, a flow control valve, and a flow controller. The electromagnet device is for building up a pulsed square wave magnetic field across the conductive liquid flowing through the non-ferrous pipe. The pair of electrodes are disposed on outer surface of the non-ferrous pipe for detecting an electromotive force induced by Faraday's induction law. The flow control valve is disposed in the non-ferrous pipe for controlling amount of flow. The flow controller is configured to receive output signal consisting of the induced electromotive force from the pair of electrodes and control the flow control valve base on the measured flow amount. | 02-16-2012 |

20090133780 | Portable supporting frame for cutting machine - A portable supporting frame for a cutting machine includes a leg frame, a tabletop frame, and a frame locker. The leg frame includes two opposing pairs of first and second supporting legs. The tabletop frame includes two table arms pivotally connected to the first crossed legs respectively. The frame locker is used for locking the top ends of the second crossed legs to the table arms respectively to retain the portable supporting frame at a set up position. When the frame locker is released, the tabletop frame is adapted to pivotally fold at 180° to overlap on the folded leg frame at a folded position. | 05-28-2009 |
20100123980 | Electrical power diagnostic system - An electrical power diagnostic system includes a system housing, a power saw management system, and a user interface. The system housing is electrically connected with the power unit of the power saw, wherein the system housing includes a control panel provided thereon for allowing a user to adjust an operational parameter through the control panel. The power saw management system includes a control processor mounted within the system housing to electrically communicate with the power saw, wherein the control processor is pre-programmed to manage operational parameters of the power saw and supervise actual operation of the power saw machine and the saw blade in such a manner that when abnormal operating condition of the power saw machine is detected, the control processor is adapted to selectively adjust the operational parameters of the power saw machine for stopping the abnormal operating condition from continuously happening. | 05-20-2010 |
20120174905 | Ground level portable saw machine - A portable saw machine includes a supporting frame, a cutting blade provided at a lower front side of the supporting frame for cutting the object at the ground level, a power device supported by the supporting frame for driving the cutting blade to rotate, and a power cutting arrangement. The power cutting arrangement includes a blade supporting frame movably extended from the supporting frame to suspendedly and adjustably support the cutting blade in a substantially horizontal orientation; and an actuating unit adapted to manually actuated to drive the blade supporting frame to adjust an elevation of the cutting blade so that when the cutting blade is driven to rotate by the power device, the cutting blade is arranged to cut the object at the ground level along the predetermined path without requiring a user to pivotally lift up the main frame. | 07-12-2012 |
