Abstract: A server includes a mother board, a back board and a bridge board. A plurality of first connection lines and a first slot are disposed on the mother board. The first connection lines are employed for delivering a plurality of power signals and a plurality of control signals. A second slot is disposed on the back board. The bridge board has a first golden finger and a second golden finger, and a plurality of second connection lines are disposed on the bridge board and is electrically connected to the first golden finger and the second golden finger. The first golden finger and the second golden finger are respectively inserted into the first slot and the second slot. In this way, the control signals and the power signals from the mother board are delivered to the back board through the second connection lines on the bridge board.

Abstract: An electronic device with fans is provided according to the present invention. The electronic device with fans includes an opening on a lid body of electronic housing, wherein one or more engaging portions are disposed on the rim of the opening, and the fans are engaged with a shield panel. While the fans are installed in the electronic device via the opening, the rim of the shield panel is engaged with the engaging portions to seal the opening. While maintaining, testing or replacing the fans, the fans are removed from the electronic housing by taking off the shield panel without opening the lid body.

Abstract: The invention provides a power switch device for electronic systems equipped having a power module. The power switch device includes a first switch for activating a first signal, a second switch for activating a second signal, a logic judging module for receiving the first and second signals for logic algorithm processing, and a control module electrically connected to the electronic system and the logic judging module. The control module is adapted to generate and transmit on and off signals of the electronic system to the logic judging module. Further, the control module controls switching on the power module according to the off signal and the logic algorithm processing based on the first signal, and also controls switching off the power module according to the on signal and the logic algorithm processing based on the first and second signals.

Abstract: A handheld spectrum scanner has a radio module, a central processing unit (CPU), a display module, a power module for supplying power, and a switch setting module acting as controlling interfaces for inputting scan conductions. The radio module comprises an antenna, a filter amplifier, a transducer and a demodulator. The antenna receives frequency signals of wireless electric waves. The filter amplifier amplifies the frequency signals. The transducer and the demodulator analyze energy of the frequency signals and output scanned result to the CPU. The CPU compares variation of voltage level of the scanned result from the radio module based on scan conductions inputted by the switch setting module, and outputs determined result. The display module has a display for displaying the determined result from the CPU.

Abstract: An insect proof wind generating device comprises a body having an wind inlet and a wind outlet; a wind driver being installed within the body; the actuation of the wind driver being controlled by a circuit board; the circuit board being connected to a magnetic sensor; the magnetic sensor serving for detecting the opening and closing of a door or a window. When it is determined that the door or window is opened, the magnetic sensor will actuate wind generating device to blow wind. The wind driver includes a motor electrically connected to the circuit board and at least on fan driven by the motor. The circuit board is installed with a voltage reduction protection unit for reducing a voltage reduction protection unit for reducing a high voltage to a low voltage suitable for the magnetic sensor.

Abstract: A bond positioning method for a wire-bonding process and a substrate for the bond positioning method are provided. At least one solder mask mark is formed in a solder mask layer on the substrate, such that during the wire-bonding process, the solder mask mark serves as a reference point for determining deviation of the solder mask layer and performing coordinate compensation according to the deviation so as to re-define positioning of a second bonding point of a bonding wire. This can overcome defects relating to bonding wires such as bending, cracking, or detachment of the bonding wires caused by undesirable contact between the bonding wires and the solder mask layer in the conventional wire-bonding process, thereby improving the production yield of the wire-bonding process, reducing material costs associated with defective products, and reducing the overall fabrication costs.

Abstract: An input device for providing positional and altitude information to a computer is disclosed. The computer input device includes a movable hand-held shaft, two suspending elements, plural position sensors and a microprocessor. Data for six degrees of freedom can be calculated by a defined algrorithm and mapping method. Data can be sent via an input/output interface to move a cursor, a viewpoint, or a position and orientation of a virtual object on a display.
