Abstract: In a fan noise canceling system, a feedforward signal generated when a fan speed change occurs and a feedback signal read by a sensor are sent to a signal amplifying unit for signal amplification, and the amplified signals are then sent to a signal converting unit for converting into a digital signal. A hybrid controller receives and corrects the digital signals sent thereto, and conducts rapid convergence algorithm to derive a reverse digital signal. The reverse digital signal is sent back to the signal converting unit for converting into a reverse analog signal, which is then sent to the signal amplifying unit for power amplification and generating a control signal to drive a loudspeaker to produce a reverse acoustic wave, which cancels out wave of fan noise to effectively reduce fan noise without adversely affecting the heat dissipation effect of the fan.

Abstract: In a communication machine room wideband noise suppression system, a sensing unit detects a noise source produced by a fan during the operation thereof and generates a noise input signal and a feedback signal, which are sent to a signal amplifying unit for signal amplification. The amplified signals are then sent to a signal converting unit and converted into digital signals. A multi-channel hybrid controller receives the digital signals and makes corrections and conduct rapid convergence algorithm to derive a reverse digital signal, which is sent to the signal converting unit and converted into a reverse analog signal. The reverse analog signal is sent to the signal amplifying unit for power amplification to generate a control signal for driving a loudspeaker unit to produce interfering acoustic wave, so as to cancel out the noise source and achieve the purpose of eliminating wideband noise.

Abstract: A memory card connector includes an insulating housing having a base board defining longer cavities thereon. Each longer cavity has a guiding cavity having two first mounting grooves. The guiding cavity extends rearward to form a connecting cavity being wider than the guiding cavity. The bottom of the connecting cavity extends rearward at one side to form a first receiving cavity, and the other side of the connecting cavity extends rearward to form a second receiving cavity. Longer terminals received in the longer cavities have a base portion having two restraining portions protruding from two sides of the base portion. The rear end of the base portion stretches rearward to form a connecting portion wider than the base portion. One side of the connecting portion extends rearward to form a fixed portion, and the other side extends rearward to form a contacting portion spaced away from the fixed portion.

Abstract: A method of fabricating a liquid crystal display (LCD) panel. The LCD includes a first substrate positioned on an upper stage in a vacuum chamber, and a second substrate positioned on a lower stage in the vacuum chamber. A predetermined gap remains between the first substrate and the second substrate. The method includes vacuuming the vacuum chamber and horizontally aligning the first substrate with the second substrate. Following that, a first affixing process is performed to press a first portion of the first substrate on at least a dummy sealant on the second substrate. A second affixing process is then performed to press a second portion of the first substrate on a main sealant on the second substrate, thus completing combination of the first substrate and the second substrate.
