Abstract: The disclosed embodiments relate to automatically enabling unconstrained inputs of data, e.g., related to quantities of a proposed trade order for submission to an electronic trading system from parties in an electronic data transaction system that enforces constraints, e.g., a maximum precision in specified quantities, on the inputs relating to the proposed trades that can be submitted by the counterparties. The disclosed embodiments relate to a user interface and system that enables a participant to specify quantities for trades with an increased precision, e.g., fractional quantities, enabling more precise alignment of the transactional characteristics with the specific goals of the participant, in an electronic trading system which constrains tradeable quantities to a maximum allowable precision, e.g., such as whole number quantities, based on business and/or regulatory requirements, e.g., requirements which dictate, for example, that transactions may only take place in whole number quantities or units.

Abstract: The invention is an apparatus for the practice of perfecting the blowing technique of a woodwind instrument, specifically bagpipes. The device is designed to resemble the mouthpiece of a bagpipe and chanter, having a round elongated and narrow blowpipe similar to most bagpipes. The device allows the user to turn a dial that will in turn change the resistance of the air passing through the device as the user blows. The device may be dialed so that air passes freely with minimal resistance for a beginner and may later be dialed as to increase the resistance as the user becomes more competent in blowing and thereby has more resistance causing the user to build up his/her ability in blowing against a simulated firmer reed.

Abstract: A laser surgery method is disclosed for use in efficient ablation of tissue with little or no thermal damage to adjacent tissues. The wavelength of the surgical laser is tuned to an absorption peak of a proteinaceous material or functional groups contained therein, the amides for example. A suitable power level is chosen to either vaporize or liquify the targeted tissue.
