  • Publication number: 20140144965
    Abstract: A method for manipulating a glass sheet compound shape during a severing operation including, for example, positioning a scoring device against the first side of the central portion of the glass sheet, and temporarily bending an extended portion of the glass sheet located between the scoring device and a selected one of the edge portions from a first orientation to a severing orientation by applying a force to the extended portion of the glass sheet. In one example, the force can be applied to achieve a predetermined surface stress in the glass sheet. The method can further include forming a score line along the first side of the central portion of the glass sheet while the force is being applied to the extended portion, and breaking away the selected one of the edge portions from the glass sheet along the score line.

  • Patent number: 8593207
    Abstract: A limiting amplifier with an input stage with dc offset cancellation, identical gain stages, an output buffer and a feedback filter. The input stage receives a differential input signal and outputs a first intermediate differential signal. The gain stages are cascaded to amplify the first intermediate differential signal and generate a second intermediate differential signal, amplified by the output buffer to produce an output signal. The feedback filter provides a dc offset voltage of the output signal to the input stage for the dc offset cancellation. The input stage comprises a resistor network coupled between a pair of input nodes and a power line and comprising a common resistor, a pair of load resistors and a shunt resistor. The load resistors share a common terminal connected to the common resistor that is connected to the power line. The shunt resistor has two terminals respectively connected to the load resistors.

  • Patent number: 8395452
    Abstract: An exemplary signal amplification circuit includes an input stage, a plurality of output stages and a selecting stage. The input stage has an input node for receiving an input signal and an output node for outputting an intermediate signal. The output stages are coupled to a plurality of output ports of the signal amplification circuit, respectively. Each output stage generates a corresponding processed signal to a corresponding output port according to a gain and the intermediate signal when enabled. The selecting stage selectively couples the output node of the input stage to at least one of the output stages. The signal amplification circuit outputs a first number of processed signal(s) when operated under a first operational mode, and outputs a second number of processed signal(s) when operated under a second operational mode.
