  • Patent number: 8405431
    Abstract: A line driver includes the following. A current replication unit replicates a reference current according to an input signal. A current mapping unit adjusts a number of P channel transistors connected in parallel and inside the current mapping unit according to control information, so as to amplify the reference current according to a magnification value. A first resistor is electrically connected between the current replication unit and a direct-current voltage. A second resistor is electrically connected to the current replication unit and the current mapping unit and generates an output signal. A signal detection unit performs integration on a part of a difference between the input signal and the output signal, thereby generating an integration signal. A magnification control unit gradually adjusts magnification information related to a reference signal, and updates the control information by the magnification information when the reference signal is equal to the integration signal.

  • Patent number: 8323473
    Abstract: A method for monitoring machining in an electroerosion assembly having a power supply and an electrode arranged across a gap from a workpiece, includes measuring a voltage at a point in a voltage waveform after a time delay td of one half of a pulse width of the voltage waveform. The measurements are repeated for multiple pulses of the voltage waveform to obtain multiple voltages, each of the voltages corresponding to a point in respective pulses. The voltages are averaged to obtain an average voltage, which is compared with at least one threshold voltage, to determine whether the machining is in control. A control signal is generated if the comparison indicates that the process is not in control, the control signal being configured to regulate an operating parameter of the power supply, and the control signal is supplied to the power supply, if generated.

  • Patent number: 8303178
    Abstract: A temperature detecting device includes a current source, a plurality of resistors, a binary counter, a multiplexer, a comparator and a control logic. The current source provides a PTAT current. The resistors provide m voltage signals with ascending or descending voltages. The binary counter generates a binary select signal having (n+1) bits. The m voltage signals are selectively outputted from the multiplexer as a multiplexer output signal according to the binary select signal, wherein 2n<m<2n+1. The comparator is used for comparing the multiplexer output signal with a reference voltage, thereby generating a comparing signal. The control logic is for issuing the start signal. If the comparing signal has a level change, the control logic controls the binary counter to record the binary select signal as a binary temperature signal. The reference voltage does not vary with temperature.
