Abstract:
A self-protection device of water-cooled heat dissipation system, applicable to a computer, includes a circulation route for a suitable amount of coolant flowing therein along a water tank, a pump and a heat exchanger; and a control module, electrically connected between the water-cooled heat dissipation system and a power supply of the computer system, for detecting whether if the water-cooled heat dissipation system is at a normal state. The control signal of the control module is to allow the computer turning on when the water-cooled heat dissipation system is checked normal. Otherwise, the power supply of the computer is stopped and an alarm is generated when the water-cooled heat dissipation system is abnormal.
Abstract:
A resonant amplifier is provided. A resonant inductor is connected in series between a source (emitter) of a common gate (base) transistor and an input point (i.e. output point of previous stage), and a resonant capacitor is connected between the input point and a ground or a voltage source connected to a loading end, such that a lossy resonant cavity is formed for carrying out resonance to amplify the signal. Then, the amplified signal is drawn out by the common gate (base) architecture. Therefore, the gain of the resonant amplifier can be boosted at desired frequency.
Abstract:
A method and device for wireless monitoring of system status is provided. The method employs a radio frequency identification (RFID) transponder and a RFID reader for transmission of system status. When the system monitoring program executed in the computer device detects abnormality, it would generate a system status code and send it to the RFID transponder, where the status code is combined with an ID code into a packet and sent out by wireless devices. The RFID reader integrated in an electronic device is used to receive the packet, make reference to the reference table embedded in the electronic device to determine the specific message represented by the system status code, and finally display the ID code and the corresponding status message.
