Abstract: An apparatus and method displays an error between a first sequence of numbers and a second sequence of numbers. A plurality of respectively different algorithms is provided for comparing the first sequence of numbers and the second sequence of numbers. At least one of the algorithms is selected to compare the first sequence of numbers and the second sequence of numbers. The selected algorithm(s) are applied to the first sequence of numbers and the second sequence of numbers in order to identify the error, wherein the error is a discrepancy between one of the numbers in the first sequence and another of the numbers in the second sequence. The error is displayed by simultaneously displaying and indicating the numbers from each sequence that have the discrepancy. For at least one of the algorithms the numbers from each of the sequences have a matching associated label. At least one of the algorithms applies fuzzy matching to the numbers from each of the sequences.

Abstract: A database is managed by at least partly shifting the burden of maintaining contact information current to the individuals registered in the database. A database manager will, if necessary, automatically generate requests for updated information, and provide incentives upon compliance with such requests.

Abstract: An arrangement for use in training players of a game during a simulated game session in the correct use of a game implement that has to be moved properly during an actual game to encounter a ball and impart to the latter a desired trajectory of movement after impacting the same includes light-emitting devices that emit at least one initial and two subsequent detection light beams from locations arranged at the corners of a triangle into substantially vertically oriented upwardly conically diverging spatial sectors. A reflective surface associated with the implement reflects the light of the respective detection light beam back to the respective location as the implement passes through the respective spatial sector with an intensity that is in a predetermined functional relationship when reaching the respective location to the distance of the reflecting means from the same location and to the degree of penetration of the reflecting means into the respective spatial sector.
