Method and system for digital watermarking of multimedia signals

Disclosed is a method and system for digital watermarking of multimedia signals. The input multimedia signal is represented using an inverse difference pyramid decomposition. Spectrum coefficients may be calculated for each level of the pyramid using a new kind of complex Hadamard transform, the matrix of which is distinguished from the known ones by the fact that only one-fourth of its coefficients are complex numbers. The phases of a previously selected part of the low-frequency coefficients are modified with the watermark data, limiting the angles of the phase changes in a gap of several degrees only. After an inverse complex Hadamard Transform, the values of the coefficients from all pyramid levels are summed up and the result is the watermarked signal. The watermark can contain multiple independent levels for each level of the pyramid.

Method and system for calibrating the scan amplitude of an electron beam lithography instrument

A method for calibrating the scan amplitude of an electron beam lithography instrument by determining the position of a feature within the scan. The method is effective at the operating frequency of the scan and using a limited bandwidth video signal including the steps of determining the reference feature to be an edge over which the video signal rises abruptly from a background level to a white level. The method turns the beam on only over a short region of the scan and represents the degree of overlap between the beam on portion of the scan and the white part of the feature as the total video signal accumulated in that scan.

LED driver with ability to operate at arbitrarily low input voltages

An LED driver with ability to operate at low input voltages is disclosed. The LED driver comprises a boost converter to boost an input voltage to a desired output voltage to power one or more LED strings. The boost converter incorporates a first controllable switch, such as a metal-oxide-semiconductor field-effect transistor (MOSFET), IGBT, etc., for output voltage control. The boost converter receives input from an external source, such as a battery voltage, as power source for voltage boost operation. The first controllable switch couples to a gate driver powered by a linear regulator, which switchably couples to different voltage sources via a second switch to ensure that the gate driver is able to provide enough voltage for switching the first controllable switch.
