From Engadget: Wolfson confirms the Samsung Galaxy S III uses its audio chip

Wolfson confirms the Samsung Galaxy S III will use its audio chip

The Galaxy S III was widely tipped to possess a Wolfson digital-to-analog converter for high quality audio output — a feature not seen in this range since the first Galaxy S. That notion has just been confirmed by the Scottish electronics firm itself, which says its WM1811 Audio Hub has been selected for use in Sammy’s flagship. The chip promises “crystal clear voice call quality” and “enriched audio playback for music and video” thanks to its 24-bit hi-fi DAC, active noise reduction circuits and other wizardry. The GS II, meanwhile, used a Yamaha DAC to convert digital data (e.g. in an mp3 file) into an analog signal that could drive a speaker (for example in your headphones), but even if most people couldn’t hear the difference, audiophiles have insisted they preferred the sound in the older Galaxy. The only question remaining, which the PR after the break does not expand upon, is whether the Wolfson hardware is found in all variants of the new phone.

From Engadget: New wireless transmission tech hits 2.56Tbps, leaves WiFi feeling inadequate

New wireless transmission tech hits 256Tbps, leaves WiFi feeling inadequateStoked about the gigabit speeds your new 802.11ac WiFi router is pumping out? One group of scientists hailing from NASA’s Jet Propulsion Laboratory and universities in the US, Israel and China isn’t so impressed, having generated a wireless signal clocking in at 2.56Tbps. Proof of the feat was published in Nature Photonics, which details their use of orbital angular momentum (OAM) to make the magic happen. Current wireless protocols alter the spin angular momentum (SAM) of radio waves to hold info, and by combining both methods the team was able to pack eight data steams into a single signal, resulting in the mouth-watering number noted above. The best part is, applying different levels of OAM twist to SAM-based transmissions theoretically allows an infinite number of streams per signal, meaning seriously increased bandwidth without the need for additional frequency. So far the wireless tests have only been conducted over a measly 1m, but the scientists reckon it’ll work at distances up to 1km and that the concept could also be used to boost speeds in existing fiber-optic cables. As with many scientific advances, it’s unlikely hardware capable of such speeds will be available any time soon, so 802.11ac will have to suffice… for now.

From Droid Life: PGM Nexus App Allows for Gesture Controls While Display is Off

Gestures are always a neat and popular way to control our devices. With a new app called PGM Nexus, you can use them to control your smartphone even when the screen is off. For example, a gesture that is already preset in the app is for “slide2wake,” where you simply swipe from left to right on the display while it’s off to wake the device.

It works like a charm, but it is for Galaxy Nexus phones that are rooted only. Sorry, non-rooted owners. Give it a go and let us know what you think.

From Ars Technica: Louisiana sex offenders must identify themselves on Facebook

Starting August 1, a new Louisiana state law will require sex offenders to disclose their status on social networks. But in theory, that shouldn’t be necessary: Facebook and other social networks’ existing policies already forbid registered sex offenders from creating accounts.

“I don’t want to leave in the hands of social network or Facebook administrators, ‘Gee, I hope someone is telling the truth,'” State Rep. Jeff Thompson told CNN Tuesday. “This is another tool for prosecutors.”

The new bill, formally known as Act 385, was signed into law by Gov. Bobby Jindal earlier this month.

From Ars Technica: Write speeds for phase-change memory reach record limits

DRAM in computers is erased when a computer is turned off.

By pre-organizing atoms in a bit of phase-change memory, information can be written in less than one nanosecond, the fastest for such memory. With write speeds comparable to the memory that powers our computers, phase change memory could one day help computers boot up instantly.

Phase-change memory stores information based on the organization of atoms in a material, often a mixture of germanium, antimony, and tellurium (Ge2Sb2Te5 or GST). A voltage pulse heats the metal and disordered atoms in the crystal rearrange into an ordered crystal. Restoring the disordered arrangement by melting the metal erases the information. A computer reads each bit by detecting the lower electrical resistance of the ordered crystal.

Micron sells small phase-change memory (PRAM) chips. Companies like IBM and Samsung are working on PRAM chips too.

From Ars Technica: Hospitals can save money just sorting their trash

A report recently published in the Canadian Medical Association Journal suggests that hospitals could save considerable sums of money by adopting a handful of common sense measures to reduce waste. The report asserts that 50 to 85 percent of regular waste is incorrectly disposed of as biohazard waste, which is estimated to cost eight times more to process. This alone can result in a hospital spending tens of thousands of dollars per year in unnecessary costs.

Operating rooms are responsible for between a fifth and a third of a hospital’s waste while consuming a much smaller proportion of a hospital’s budget. It’s on the operating room that Yoan Kagoma MD and co-authors from University of Western Ontario’s medical school have fixed their gaze. Using 65 prior studies, the team has come up with a series of money-saving waste management recommendations for hospitals and health care institutions.

The single most effective cost-saving measure a hospital can adopt is to ensure that its waste is properly segregated, the report claims. Biohazard waste costs an estimated $963 per ton to process compared to the $121 per ton for regular waste. At most, biohazard waste should make up 15 percent of a hospital’s waste. But the report claims that, due to a simple “lack of awareness” among hospital staff, between 50-85 percent of the remaining non-hazardous waste is disposed of in the same costly manner (though it should be noted this finding is based on a paper published in 1996). By properly segregating waste in its operating rooms, the University of Pittsburgh’s Magee-Womens Hospital saved more than $89,000 in 2010.
