Abstract: A process for enhancing ambience in an audio signal output that is derived from an audio signal input in a dual channel audio ambience extraction circuit. The process includes cross-coupling of audio signals in one channel with audio signals in another channel. Each of the cross-coupled signals is attenuated and delayed by an adjustable time period that is within a haas delay time and is then applied in the feedback path to a summing input of an opposite channel. At the summing input, the signals are mixed with subsequent audio signal inputs to that channel. All of the attenuated and delayed signals are continuously applied to outputs of the extraction circuit during the cross-coupling process. The output signals comprise the original signals plus delayed and attenuated reproductions of the original signal along with continuing signals that are submitted to the extraction circuit subsequent to the initial signals.

Abstract: A kickboard comprising a relatively thin, buoyant board no longer than twenty six inches. The board has a back edge and a front edge joined by side edges. The board also has top and bottom surfaces joined by the front, back and side edges. Two, spaced-apart, forearm receiving depressions are provided in the top surface of the board, the depressions extending forwardly from the back edge of the board over a major portion of the length of the board to near the front edge. The depressions help to retain the forearms of a swimmer using the board on the board. The kickboard has hand grips located in front of the forearm receiving depressions. Preferably, at least the front portions of the side edges are bent toward each other, and the hand grips are located on the bent front portions, preferably just in front of, and aligned with, the forearm receiving depressions. Gripping the bent front portions allows the wrists to remain in a normal position relative to the forearms thus reducing stress.

Abstract: Inline crossfold product and method that will provide substantially more insert sheet material than previous inline crossfold methods, and, additional inline crossfold packet configurations, is provided. A bound crossfold booklet, the equivalent of or a small catalog, which is particularly adapted for large mail distribution is provided. The substantially lower mailing cost of a six by nine inch booklet size, instead of the ordinary letter size catalog, yields substantial savings. Production and handling costs are also minimized since the booklets are bound in the inline process, thereby eliminating separate handling and binding costs, where there is a separate binding and envelope stuffing operation required.
