Abstract: An automatic gain control circuit for controlling the gain of a variable gain amplifier block includes a count control signal generating block, an up-down counter, a gain control signal generating block, and a downcount clock signal generating block. The up-down counter upcounts an upcount clock signal or downcounts a downcount clock signal according to a count control signal generated by the count control signal generating block. The gain control signal generating block generates a gain control signal corresponding to a count value of the up-down counter. The downcount clock signal generating block generates a downcount clock signal whose frequency corresponds to the count value of the up-down counter.

Abstract: A window regulator assembly is described that comprises a window bracket that is in contact with the bottom edge of the window; a cable; a carrier plate that is in contact with the window bracket and both ends of the cable; a tension spring located on each end of the cable; an upper bracket assembly; a drum housing having a cable drum; a hollow conduit located between the upper bracket assembly and the drum housing; and a drive unit. The upper bracket assembly, cable drum, and conduit are capable of slideably receiving the cable, while the tension springs provide a predetermined amount of tension to the cable in order for the window regulator assembly to move the window between open and closed positions. Many of the components of the window regulator assembly may be formed from a thermoplastic material.
