Abstract: A fan system is used for dissipating heat of an electronic device. The fan system includes a fan, a hollow structure, and a control circuit. Sound waves made by the fan are transmitted to an interior of the hollow structure when the fan is operating. The control circuit is connected to the hollow structure and is configured to control deformation/deformations of the hollow structure according to a state/states of the fan and/or the electronic device, which change a volume of the interior of the hollow structure for making a resonance frequency of the hollow structure being approximate to a rotation speed of the fan or being the same as the rotation speed of the fan.

Abstract: A method for fabricating a metal-oxide semiconductor (MOS) transistor is disclosed. The method includes the steps of: providing a semiconductor substrate; forming a silicon layer on the semiconductor substrate; performing a first photo-etching process on the silicon layer for forming a gate pattern; forming an epitaxial layer in the semiconductor substrate adjacent to two sides of the gate pattern; and performing a second photo-etching process on the gate pattern to form a slot in the gate pattern while using the gate pattern to physically separate the gate pattern into two gates.

Abstract: The present invention is an irrigation device and method for use with a water source to deliver water in an intelligently controlled manner to a sprinkler system for watering. In one embodiment, the device comprises a housing having front and rear walls, a fluid inlet conduit engaged with the front wall and adapted to engage a water source such as a spout or hose, and a fluid outlet conduit engaged with the rear wall. The device further comprises a valve unit disposed within the outlet conduit. The valve unit is operable between a closed position where water flow is prevented and an open position where water can flow thru the outlet conduit to the external sprinkler system for watering.

Abstract: A sheet cartridge, e.g. a bill cartridge, is designed for storing sheets in an automatic machine. The sheet cartridge has a housing and separators for defining a temporary space and a storage space. The housing has one or more patterned openings corresponding to pushing blocks of the automatic machine outside the sheet cartridge. The pushing blocks pushes sheets in the temporary space across the separators into the storage space via the corresponding openings so that the sheets are safe when the sheet cartridge is removed from the automatic machine.
