Abstract: A distributed power amplifier may include a plurality of switching power amplifier sub-circuits, and a plurality of connection network sub-circuits, each of the plurality connection network sub-circuits having a characteristic impedance, wherein each of the plurality of connection network sub-circuits combines two or more of the plurality of switching power amplifier sub-circuits into a parallel or series configuration, wherein the plurality of switching power amplifier sub-circuits, the plurality of connection network sub-circuits and the characteristic impedance of each of the plurality of connection network sub-circuits are configured to present each of the plurality of switching power amplifier sub-circuits with a substantially equivalent load impedance.

Abstract: Traditionally, a computer chess program will take the current state of the board (the position of the pieces in play) and using a database of moves, it will select what it feels is the best move. This is how every computer chess program works. The Omnipotent Opponent uses an entirely different approach. In a game of chess there is a finite sized board (8×8 squares), and finite number of pieces (16 black and 16 white). At any given time only a finite number of pieces can move and they can only move in a finite number of directions. Therefore, it is possible to plot every single move that could ever be made in a game of chess and every resulting outcome of the game. Once this data has been generated, it could be analyzed in reverse (working from the end game to the start) and each phase of the game could be marked with the best move. Using this best move data, one would always know the best move to make at any point in any chess game. Equipped with this information, one would never loose.

Abstract: A continuous inkjet device emits a stream of fluid from nozzles. Droplet break-off is stimulated by the application of external perturbing stimulus to the stream in a manner that controls the formation of satellite drops. Satellite behavior is controlled by the use of a composite perturbing signal, composed of at least two frequencies that are not harmonically related, but are related by the ratio of small integers. In one embodiment, the use of two perturbing signals with frequencies fL and fH having a ratio of M/N, where M and N are integers, and M is not a multiple of N, and N is not a multiple of M, produces a repeating drop pattern of either M or N drops at the beat frequency of the combined signal, the constituent drops in said repeating pattern have different satellite formation characteristics.
