Abstract: The present disclosure provides a lockout mechanism for use with a dynamic therapeutic assembly having a pivot bar pivotally coupled to an upper pivot plate such that the upper pivot plate is moveable with respect to the pivot bar about a first pivot axis and pivotally coupled to a lower pivot plate such that the pivot bar is moveable with respect to the lower pivot plate about a second pivot axis that is substantially perpendicular to the first pivot axis. The lockout mechanism includes a pushrod assembly that is moveable between a first position, wherein a portion of the pushrod assembly is engageable with the pivot bar to prevent substantial movement of the pivot bar about the second pivot axis, and a second position, wherein the portion of the pushrod assembly is disengaged from the pivot bar to allow movement of the pivot bar about the second pivot axis.

Abstract: A method of crosstalk correction comprises producing a calibration image having different printed image densities in grayscale, measuring the printed image densities at the different light exposure values to obtain a correlation of printed density in grayscale as a function of light exposure value over a range of light exposure values, obtaining experimental analytical density values for a selected light exposure value within the range of light exposure values and using the correlation of printed density as a function of light exposure value and the experimental analytical density values to correct for crosstalk.

Abstract: A method of producing a composite image on an image recording medium from first and second component images, represented by digital image data, comprising the steps of converting the digital image data of each image into electromagnetic radiation image data; and forming the composite image by successively exposing the recording medium to the electromagnetic radiation image data of the first and second images so that the images are created on the medium in overlapping relationship to form a join region. The medium is doubly exposed, first by the image data of the first image and then by the image data of the second image. The intensity of the electromagnetic radiation representing the first image is progressively ramped off in the join region and the intensity of the electromagnetic radiation representing the second image is progressively ramped on in the join region.

Abstract: A method of producing an image on a printing medium comprises producing a pulse train of modelocked laser pulses, providing a source of image input data in the form of a series of gate pulse of varible length and modulating the pulse train with reference to the gate pulses to produce a gated pulse train for producing the image on the printing medium. An apparatus for carrying out the method is also provided.

Abstract: A mode locked pulsed laser incorporates an intracavity element to compensate for the dispersion caused by other intracavity elements. This element reduces the tendency of the pulse to broaden in the cavity due to group velocity dispersion and results in very short pulses. In the laser of the present invention, mode locking is initiated by detecting the beat frequency between adjacent longitudinal modes using a high speed photodiode. This signal is amplified and then the frequency is divided by two. The signal is passed through an electronically adjustable phase shifter and then to a power amplifier. This signal is applied to the acousto-optic modelocker. If the cavity length drifts the beat frequency between the longitudinal modes changes. The rf signal applied to the modulator changes in exactly the right manner to track the drift in cavity length. Thus the modelocker is automatically synched to the round trip of the laser cavity.
