Abstract: In general, the invention is directed to data exploration and visualization techniques. In one embodiment, the invention provides a method comprising accessing Multivariate Curve Resolution data having a plurality of components to identify a set of combinations of the components, wherein each of the combinations includes at least two of the components; and presenting a user interface having an input region associated with each of the combinations, wherein each of the input regions has a visual indicium generated as a function of a degree of correlation between components in the respective combination.

Abstract: A reference area usable with a rectangular form when the form is used with a computer controlled printer. The reference area having a pattern and a reference point. The pattern allowing the location of a mark printed by the printer on the pattern to be readily identified on an equivalent reference area displayed on a display monitor for the computer. The reference point is positioned so it will receive a reference mark when printed on the reference area by the printer provided the form is not misaligned in the printer. A reference mark received at the reference area provides information relative to the reference point that is a measure of the amount of vertical and horizontal misalignment of the form in the printer. This information, when placed in the computer, makes it possible for the computer to correct for any misalignment before any printing is done on the form.

Abstract: A respiratory exerciser which includes a hollow tubular body having at least two openings at one end and an opening at the other end. A piston is reciprocally slidable in the tubular body. A mouthpiece assembly is removably connectable to one opening at the one end of the body so that when the patient inhales and exhales the piston will reciprocate accordingly. Adjustment structure is on the one end to regulate the size of at least another of the openings therein to control the size of the access opening to atmosphere at the one end as the patient breathes through the mouthpiece assembly. An indicator is associated with the adjustment structure to designate the relative size of the access opening to atmosphere at the one end. The structure permits use of the device as an exerciser for inhaling or exhaling and provides adjustment for accommodating changes in strength required by the patient in the exhaling and inhaling exercises.
