Enhanced Music and Audio Via Embedded Data in MP3 Files

A technique for embedding data in an mp3, but not in the header file. The metadata is not easily removed by a hacker without significantly destroying the audio. The data capacity depends somewhat on the nature of the music, but is of the order of tens of kb/minute, with no change in the size of the mp3 file. Applications Data embedded in...

Image sensor with a Current Sensing Active Pixel (CSAP)

This is an improved CMOS image sensor, which is 40 times faster than conventional CMOS image sensors, operating from a 3.3 V power supply, with significantly lower 1/f noise. The circuit utilizes the standard APS design and retains the high fill factor in a 0.35 µm standard CMOS process. In this current sensing active pixel (CSAP) sensor, the negative...
