Abstract: A method for planning a project comprises a step of distributing the project and the step of distributing the project includes a step of planning a master project, which is established by a master project initiator who inputs information about the master project to an information processing device which notifies a master project successor of the master project automatically after the master project successor is set, and the master project successor determines whether the master project is distributed after the master project successor is notified of the master project by the information processing device and inputs the determination of the master project to the information processing device; a step of planning subprojects is further comprised, and after subproject successors are notified of the subprojects by the information processing device respectively, the subproject successors input the determination of each of the subprojects to the information processing device; a step of setting predecessor tasks, whe

Abstract: A bobbin module of transformer is provided. The bobbin module includes two bobbins. Each of the bobbins comprises a body, an indentation and a hooker. The body has a lateral surface on which the indentation and the hooker are disposed. The hooker and the indentation of the bobbin are respectively engaged with the hooker and the indentation of the other bobbin so that the two bobbins are combined together.

Abstract: A transformer includes a bobbin, a primary coil, a first secondary coil, a first core, a second core and a third core. The bobbin has a through hole. The primary coil and the first secondary coil are respectively surrounded on the bobbin. The first core is embedded into the through hole. The second core is coupled to the first core to form a magnetic loop. The third core is coupled to the first core and the second core and located between the primary coil and the first secondary coil. The third core having high impedance is fastened on the second core or the bobbin alternatively. A light tube driving circuit with the above transformer drives a discharge lamp.

Abstract: A motion sensitive device for causing an electronic signal to be sent to one or more output devices, comprising a printed circuit board, a battery connected to the printed circuit board, electrical circuitry connected to the printed circuit board, a motion sensitive switch connected to the printed circuit board, electrical output devices such as light emitting diodes connected to the printed circuit board and electrical circuits all providing means whereby the motion sensitive switch causes a signal to be transmitted to the output device when movement is sensed by the switch. The device is small enough to be used in wearing apparel and can provide safety vis-à-vis increased visibility for the user.

Abstract: A spanner has a handle bar, a box head disposed on the handle bar, a ratchet ring, a C-shaped retainer, a spring, and a serrated block. The box head has an arc-shaped guide wall, an inner aperture, and an inner groove. The ratchet ring has a plurality of ratchet teeth. The serrated block has a plurality of ratchet serrations, an arc-shaped blocking face, and a blind hole. The serrated block is inserted in the inner groove of the box head. The spring has a first end inserted in the blind hole of the serrated block, and a second end inserted in the inner aperture of the box head. The C-shaped retainer surrounds the ratchet ring. The ratchet ring is inserted in the box head to be engaged with the serrated block.

Abstract: Electronically focused and automatically scanning acoustic bulk waves are produced by scattering chirp acoustic bulk waves at grazing incidence from an acoustic grating. The same apparatus may be used in reverse to convert diverging acoustic bulk waves produced by a focused beam into chirp acoustic bulk waves. A pulse compression filter then converts the chirp waves into signals describing the source.
