  • Publication number: 20110075250
    Abstract: A laser scanning beam reader is provided. When a round-grating-dot matrix is in a stationary state, the laser beams passing through the round-grating-dot matrix result in line-shaped refraction beams. By the laser scanning beam reader, the motor system conventionally used for rotating the hologram disc to successively generate dot scanning beams as the line-shaped will be omitted. As a consequence, the components and configurations of the laser scanning beam reader are simplified and the cost thereof is reduced.

  • Publication number: 20110012862
    Abstract: A sensing method for a capacitive touch panel includes charging a measure capacitor, setting the voltage across a mutual capacitor at the intersection of two traces of the capacitive touch panel, and then injecting partial charges of the measure capacitor into the mutual capacitor. When the intersection is touched, the capacitance value of the mutual capacitor is changed, and consequently the amount of charges injected into the mutual capacitor is changed. Hence, the voltage of the measure capacitor could be detected to determine whether or not the intersection is touched.

  • Publication number: 20070022773
    Abstract: A cooling energy saving structure, capable of connecting to a PCB multi-axial driller, includes a chiller, a freezing dryer, and a thermal superconductive recycling device, where the chiller has a liquid outward piping and a liquid inward piping, the freezing dryer has a gas outward piping and a gas inward piping, and the thermal superconductive recycling device accommodates the liquid inward piping of the chiller and the gas outward piping of the dryer. The device further features cooling the liquid in the inward piping before it flows back to the chiller, and heating the gas in the outward piping before it is discharged. The heat exchange performed between the flow back liquid of the chiller and the discharged gas of the dryer takes advantage of the device, which proves to have substantially cut down energy consumption and power expenditure for a very effective use of energy resources.

  • Publication number: 20060290891
    Abstract: A device for cooling a light emitting diode projector includes a first cooling unit that includes a hollow portion. One end of the hollow portion includes a third cooling body and a reflection cover. The light emitting unit is adhered to one surface of the third cooling body, while the light source is projected corresponding to the reflection cover. A connection unit is disposed on the other end of the hollow portion, which can convey power source to the light emitting unit. The heat generated from the light emitting unit is directly absorbed into the third cooling body, and is transferred to the first cooling unit for performing heat exchange. The light emitting diode projector can thus obtain a better cooling effect.

  • Patent number: 7032652
    Abstract: A heat conductive plate includes a hollow case and a plurality of grooves respectively formed on the inner top wall and the inner bottom wall of the case. In addition, a plurality of supporting members are positioned in the case by way of powder sintering, wherein each surface of the supporting members has a porous wick structure formed thereon. Thus, the case can be sustained by the supports with each wick structure firmly mounted in the grooves of the inner walls thereof. When performing heat transferring, the working fluid is heated to be formed as vapor by the electronic element mounted on the outer bottom surface so as to flow toward the inner top surface of the case. The working fluid is then cooled to be liquid again to be absorbed by the wick structures of the supporting members and be transported toward the inner bottom of the case.
