Abstract: The invention provides a method for processing a frame-recording based video clip without the need of modifying the video clip and/or directly inserting any form of signals into the video clip. The method comprises the steps of: browsing the video clip frame by frame by a video editing software; importing a grid layer into the video editing software such that the grid layer is browsed synchronously with each frame of the video clip; analyzing movement of a character and/or an object in the video clip by the grid layer; generating a series of game data to record the movement; storing the series of game data in a game unit after the generation of the game data; and connecting a game input to the game unit to activate the game, wherein the game unit receives input data from the game input when the video clip is played and synchronously compares the input data with the game data to determine whether they matches with each other.

Abstract: A piezoelectric accelerometer comprising a housing with two complementary parts (2005, 2006) in which a metal mass (2002) and an abutting piezoelectric element (2003) movably mounted in place are sandwiched between two conductive contact elements (2001, 2004), wherein the metal mass (2002) is in intimate contact with the piezoelectric element (2003) and the two conductive contact elements (2001, 2004) act as the electric terminals for connecting the accelerometer to any external electronic circuit for further processing.

Abstract: A silent method of, and apparatus for use in, enhancing the quality of sound from an electrically powered audio equipment assembly. The apparatus includes an electrical signal conducting component which forms a part of a home audio equipment assembly. The method includes the step of applying a pulsed digital signal having a wide and continuous range of frequencies within the audio frequency bandwidth to the electrical signal conducting component. The signal is applied at a signal level which is a substantial fraction of the maximum signal level rating of the component for a prolonged period of time.
