Submission + - US Supreme Court upholds removal of works from Pub (wsj.com) 2
langelgjm writes: While much of the web is focused on the SOPA and PIPA blackout, supporters of the public domain today quietly lost a protracted struggle that began back in 2001.The Supreme Court, in a 6-2 decision, rejected the argument that Congress did not have the power to convey copyright upon works that were already in the public domain. The suit was originally filed to challenge provisions that the U.S. adopted when signing the TRIPs agreement. Justices Breyer and Alito dissented, arguing that conveyed copyright on already existing works defied the logic of copyright law. Justice Kagan recused herself. The text of the opinions is available here (PDF).
Submission + - Apple provides patents to patent troll so they can (techcrunch.com)
An anonymous reader writes: Apple, further showing that they're willing to abuse the patent system however possible, has now teamed up with a patent troll.
Over the last two years, Apple has been engaged in vicious legal battles over smartphone patents, many of which are aimed at squelching (or squeezing money out of) manufacturers of devices running Android. And now, for some reason, it has given valuable patents to a patent troll — which is using them to sue many of the top technology companies in the world.

dell623 writes: "Techcrunch have posted a story about the patent troll company Digitude Innovations that recently filed suit with ITC suing all major mobile manufacturers except Apple. It turns out DI is a patent accumulating and licensing company and the patents it is using to sue were owned by Apple until recently before being transferred via a shell company. The patents in question are typical software patents that could be said to be infringed by every smartphone."

Submission + - Ask Slashdot: Image recognition for race timing?
int2str writes: Slashdot, Autocross (http://en.wikipedia.org/wiki/Autocross) is a form of motorsports practiced in the US and around the world where car enthusiasts explore the capabilities of their car in an open parking lot or similar suited area. It's point-to-point racing (not closed circuit). Most of these events are organized by car clubs and volunteers.
Timing is usually done with a form of detection beam at start and finish that gets interrupted by the car crossing the beam. Many commercial systems are available. All of these system require the operator to enter the car's number or ID and requires the cars finishing in the order they started. So if one car is not able to finish, the operator has to intervene, or timing is broken.
For closed circuit racing, transponder systems are available to address this problem. But such systems require sensor loops in the track or overhead (bridge setup) and the transponders are expensive.
Do you think it would be possible to design a timing system using off-the-shelf parts and open source solutions to uniquely distinguish about 100 participating vehicles and time them from a start to a finish point, independently of their finishing order?
My initial idea would be:
- Use (web-?)cameras at each end that feed into a Linux based notebook (USB/Ethernet).
- Start recoding still images as fast as possible when motion is detected
- Identify unique shape, numbers, barcode, qr code or similar in the images, that have been attached using a magnet to the vehicle's door.
Difficulties to overcome:
- Camera with high enough shutter speed to get recognizable image of vehicle traveling 30-60mph
- Quickly and accurately identify a unique symbol or shape
So far I've started looking into OpenCV as a possible tool for image recognition, but have not been able to find a capture solution.
Does anybody have experience with something like this?
The solution would be open source and well documented as to benefit the many car clubs around the country and the world.

angry tapir writes: "The intellectual property lawsuit between Oracle and Google over the Android mobile OS won't go to trial until next year, according to a ruling made in the U.S. District Court for the Northern District of California by the judge overseeing the case. The trial was initially set to begin Oct. 31 but was postponed last week by Judge William Alsup due to scheduling conflicts with a major criminal trial. The trial will be split into three stages heard by the same jury. In step one, "liability on the copyright claims, including all defenses thereto, will be tried and determined by special verdict before going to Phase Two," he wrote. The second phase will cover liability on the case's patent claims, he added. "The jury will decide these issues before going to Phase Three." In the final stage, "all remaining issues will be tried, including damages and willfulness"."

sciencehabit writes: An international research team has diagnosed what ailed an ancient Egyptian known only as M1. He had the oldest known case of prostate cancer in ancient Egypt and the second oldest case in the world. Moreover, the new study suggests that earlier investigators may have underestimated the prevalence of cancer in ancient populations because high-resolution computerized tomography (CT) scanners capable of finding tumors measuring just 1 to 2 millimeters in diameter only became available in 2005.

The lawsuits, from the Electronic Frontier Foundation and the American Civil Liberties Union, seek to have the DOJ and its U.S. Federal Bureau of Investigation branch turn over all information related to information requests allowed under Section 215 of the Patriot Act. Section 215 allows the FBI to ask for a court order to obtain "any tangible things," including books, records, papers, and documents, related to a terrorism investigation."

derGoldstein writes: Ars has an article up discussing new measurements of Eris, the largest dwarf planet in our solar system: "New measurements are suggesting that Eris may actually be more like Pluto’s twin. The newly measured radius of Eris puts it within the error range of the accepted size of Pluto. ... Scientists were able to get a better handle on the size of Eris by observing it as it passed in front of a background star, a technique called stellar occultation. By observing how long Eris obscures the star (given how fast it is moving), you can determine the width of Eris at that point."
