Abstract: A fluid sample collection device for a disk-based fluid separation system is disclosed. The disk-based separation system includes a compact microfluidic disk with at least one flow channel pattern formed on a side surface of the disk. At least one orifice is formed on an outflow boundary of the disk and is designed in fluid communication with the flow channel pattern through a communication channel. The fluid sample collection device includes at least one collection tube having an open end serving as a fluid receiving end and corresponding to the orifice of the disk with a distance. When the disk is rotated, at least a portion of fluid sample in a sample processing reservoir formed on the disk is delivered by centripetal force through the communication channel and the orifice, and finally the expelling fluid sample is collected in the collection tube.

Abstract: Disclosed is a disk based platform for separating and detecting cells that are labeled with immunomagnetic beads. A disk-like carrier board forms therein at least one flow channel structure, which includes an inner reservoir for receiving a sample fluid, an outer reservoir, and a plurality of micro flow channels arranged between and in fluid communication with the inner and outer reservoirs. When the disk-like carrier board spins, cells labeled with immunomagnetic beads are attracted by a magnetic attraction unit that is arranged above the disk-like carrier board and adjacent to the inner reservoir to thereby remain in the inner reservoir, and cells that are not so labeled are acted upon by a centrifugal force induced by the spinning of the disk-like carrier board to flow with the sample fluid from the inner reservoir through the micro flow channels into the outer reservoir.

Abstract: An LCD backlight driving device with an isolating transformer comprises a DC power supply, a square wave generator, a square wave controller, said isolating transformer and a driver transformer; wherein said isolating transformer has a primary side connected to said square wave generator and a secondary side connected to said driver transformer. Since said isolating transformer is placed between said square wave generator and said driver transformer, it effectively shortens a safety distance required for setting up said driver transformer, as compared to when said driver transformer is used directly; as a result, the area for implementing a circuit board is decreased and the manufacturing cost of said device is reduced.

Abstract: A double frequency signal generator to which a synchronization signal having a duty cycle of 1% to 999% is inputted. The synchronization signal is used for triggering of a switching component at positive and negative edges to generate a triangular-wave signal. An average of voltages of the triangular-wave signal is acquired and compared with the triangular-wave signal at a comparator to generate a square-wave having a duty cycle of 50%. Then, the square-wave signal is used for triggering at positive and negative edges to generate a double frequency signal. As such, the high cost issue and the limitation of a square-wave input signal occurred in the prior art may be efficiently overcome.
