Abstract: A time to current conversion apparatus and methods. An impedance having an input for selectively receiving a time varying periodic signal or a known voltage signal is provided; and a current output is coupled to the impedance. By observing the average current through the impedance for the known voltage signal over a time period, and by observing the average current through the impedance for a time varying periodic signal, the duty cycle of the time varying periodic signal may be determined by evaluating a ratio of a first average current observed at the current output while the time varying periodic signal is coupled to the impedance to a second average current observed at the current output while the known voltage signal is coupled to the impedance. An embodiment time to current converter circuit is disclosed. Method embodiments for determining the duty cycle of a time varying periodic signal are provided.

Abstract: The present invention provides a method for eliminating a musical tone from becoming a wind shear sound, which is used for the music recording file played in the GSM mobile communication system, such as the personal ring back tone. The method is to judge a portion of the music recording file where the music tone is erroneously judged as a background music, and add a small section of silence in front of the portion, so that the GSM mobile communication system would not judge the portion of the music tone as the background music so as to effectively eliminate the generation of the wind shear sound.

Abstract: A triangle rotation engine, which comprises an oval rotor repeatedly performing Auto cycle inside a cylinder block, which defines therein three cylinder walls, for driving a crank shaft slidably linked with the oval rotor for an output of power through two axles and two fanshaped wheels pivotally connected with the crank shaft so as to achieve the performance of an internal combustion engine.

Abstract: A safety plug receptacle, comprising a shuttle means controlled by the plug which is inserted therein to connect the two conductive clamps therein, which are provided for connecting the two plug pins of said plug, to an external power supply. Removal of the plug causes the shuttle means to disconnect the two conductive clamps. Indicator lamp is mounted on the casing of the plug receptacle to give light when the two conductive clamps are connected. Hook means are respectively attached to the two conductive clamps for hooking plug pins in position. Socket means is set to isolate the two conductive clamps from each other so as to eliminate possible short circuit problem.
