  • Patent number: 8710867
    Abstract: An auto-mute control circuit is disclosed. The auto-mute control circuit includes an analog amplifier, a detecting circuit and a direct-current (DC) level adjusting circuit. The analog amplifier receives an input signal and outputs a sensing voltage signal accordingly. The detecting circuit compares a common-mode voltage received with the sensing voltage signal received and outputs a comparison signal accordingly. The DC adjusting circuit receives the comparison signal and outputs an Up-Down digital signal, a fine tune digital signal and a rough tune digital signal, so that a sensing DC level is equal to the common-mode voltage.

  • Patent number: 6199414
    Abstract: A quick release lock for a cover is provided. The cover may be a manhole cover for closing onto a manhole ring having a radially extended flange. The quick release lock mainly includes several angularly equal-spaced cross-shaped slots provided on the cover to communicate with through holes below them, and catch elements, push elements, and cotters in the same number as that of the cross-shaped slots. The catch element each is pivotally connected to and between two fixing plates provided at two opposite sides of each through hole. The cotter each is positioned in one cross-shaped slot and extended down into she through hole. The push element each is screwed on a bar portion of the cotter below the cover. When the cotter is depressed, the push element radially pushes the catch element outward to engage with a lower edge of the flange on the ring member and thereby firmly locks the cover to the ring member.
