    • An apparatus for testing the life of a leakage current protection device having a leakage current detection circuit and a trip mechanism having a switch device. In one embodiment, the apparatus a ground fault simulation unit, a fault detector of the leakage current detection circuit and the trip mechanism, and a life testing detection control unit having an MCU for controlling operation of the fault detector. In operation, a first signal (pulse signal) is sent to the gate of the switching device to generate a first voltage at the cathode of the switching device, a second signal is sent to the ground fault simulation unit to generate a simulated ground fault for the leakage current detection circuit to generate a second voltage at the gate of the switching device, and the first and second voltages are measured to determine whether a fault exists in the leakage current detection circuit and the trip mechanism.

    • A method or system of spatial-phase locking a beam used in maskless lithography provides a fiducial grid with a single spatial-period, the fiducial grid being rotated at an angle with respect to a direction of scanning the beam; detects a signal generated in response to the beam being incident upon the fiducial grid; determines frequency components of the detected signal; and determines a two-dimensional location of the beam from phases of two determined fundamental frequency component. The method or system further determines a size of the beam from relative amplitudes of the determined fundamental and harmonic frequency components and/or determine a shape of the beam from relative amplitudes of the determined fundamental and harmonic frequency components. The method or system corrects a deflection of the beam in response to the determined two-dimensional location, and/or adjusts the size of the beam in response to the determined size, and/or adjusts the shape of the beam in response to the determined shape. If the method or system spatial-phase locks a plurality of beams used in maskless lithography, a fiducial grid with a varying spatial-period is utilized. In the plural beam method or system, the frequency components for each beam are determined using frequency-division multiplexing.
