Cellphones

+ - Using Cell Phone CMOS Sensor for Gamma-Radiation

Submitted by anonymous
anonymous (22260) writes "In January of 2008, mike449 described us[ing] the CMOS sensor of the built-in camera of a cell phone to detect gamma-radiation. In May of 2008, Eric P. Rubenstein, patented using light sensitive semiconductors (such as CCD or CMOS cameras) for detection of radiation ( US 7737410). Has someone from Slashdot tried a CMOS sensor with a radioactive isotope and tested if it is better than the tin can detector?"

+ - Alternate 2009 Copyright Expirations

Submitted by jrincayc
jrincayc (22260) writes "It's nearly the end of 2009. If the 1790 copyright maximum term of 28 years was still around, everything that had been published by 1981 would be now be public domain, so the original Ultima and God Emperor of Dune and would now be public domain. If the 1909 copyright maximum term of 56 years (if renewed) still existed, everything that was published by 1953 would now be public domain, freeing The City and the Stars and Forbidden Planet. If the 1976 copyright act term of 75* years (* it is more complicated) still existed, everything published by 1934 would now be public domain including Murder on the Orient Express. But thanks to the Sonny Bono Copyright Term Extension Act nothing in the US will have it's copyright term expire until 1923 works expire in 2018."
Patents

+ - What patents exist on MPEG-1?

Submitted by
jrincayc
jrincayc writes "Is MPEG-1 still patented, and if so when do the patents expire? MPEG-2 is still patented, and some of the patents may apply to MPEG-1, but to the best of my knowledge, there are no lists of patents that apply to MPEG-1. MPEG-1 Layer-3 audio is still patented, and will be for awhile. Snazzizone claims there are no license restriction that require payment, but absent a careful study of the problem, Fedora and other US based Linux distributions will not include MPEG-1 support. If MPEG-1 with Layer 2 audio was free of patents, that would allow one video file to be created that could be played almost anywhere since both Quicktime and Windows Media Player already support it. So, does anyone know what patents MPEG-1 requires?"
