Like Button on Facebook's Sued

By Anak Ifu | At 6:11 pm | Label : , , , | 0 Comments
facebook has been sued over its “like” button by a patent-holding company that claims facebook ripped off its technology.

the lawsuit was filed in u. s. district court in virginia by rembrandt social media, the owner of patents filed by a deceased dutch programmer named joannes jozef everardus van der meer.

in step with the lawsuit, van der meer pioneered technology within the whole nineties that nowadays has been utilized on facebook.

in 1998, van der meer applied to firmly patent a technology that allowed users to firmly produce on-line diaries but a patent obtain a “related set of technologies that enabled the automatic transfer, for a user’s request, of third-party content a content-provider’s website to firmly the user’s personal diary page, ” in step with court documents.

essentially, van der meer’s patent envisioned what facebook nowadays calls its “share” and “like” buttons, the lawsuit aforesaid.

in 2004, van der meer, doing business underneath his company, aduna, registered the domain surfbook. com. in spite of this, he died that year and was unable to firmly produce his social network, court documents aforesaid.

the lawsuit claims facebook was mindful of the patents coming from the nineties and most definitely has cited them in its own patent applications.

“although mark zuckerberg failed to begin what became facebook till 2003, it bears a exceptional resemblance, each in terms of its functionality and technical implementation, to firmly the personal web page diary that van der meer had invented years earlier, ” court documents aforesaid.

facebook declined to firmly comment upon the lawsuit.

the lawsuit too names addthis, a social bookmarking service or a an early partner of facebook.

rembrandt social media is seeking damages, interest and courts prices, in step with the court documents.

New Li-ion (lithium) Battery

 a team of scientists due to university of southern california and zhejiang university in china have developed a brand new lithium-ion battery that uses silicon nanoparticles set up of the normal graphite anodes to supply superior performance.

researchers at usc have developed a brand new lithium-ion battery design that uses porous silicon nanoparticles set up of the normal graphite anodes to supply superior performance.

the new batteries — that could well be employed in something from cellphones out to hybrid cars — hold 3 times as a lot of energy as comparable graphite-based designs and recharge among 10 minutes. the planning, nowadays underneath a provisional patent, could well be commercially accessible among 2 out to 3 years.

“it’s an exciting research. it opens the door regarding the design of subsequent generation lithium-ion batteries, ” same chongwu zhou, professor along at the usc viterbi faculty of engineering, who led the team that developed the battery.

zhou worked with usc graduate students mingyuan ge, jipeng rong, xin fang and anyi zhang, too as yunhao lu of zhejiang university in china. their research was revealed in nano research in january.

researchers have long attempted make use of silicon, which is certainly cheap and possesses a high potential capability, in battery anodes. ( anodes are where current flows inside battery, whereas cathodes are where current flows out. )

the matter has actually been that previous silicon anode designs, that were basically small plates of one's material, broke down from repeated swelling and shrinking throughout charging/discharging cycles and quickly became useless.

last year, zhou’s team experimented with porous silicon nanowires which can be found under 100 nanometers in diameter and only a few microns long.

the small pores inside the nanowires allowed the silicon out to expand and contract while not breaking whereas simultaneously increasing the surface space, that in flip allows lithium ions out to diffuse in and out from the battery a lot of quickly, improving performance.

though the batteries functioned well, the nanowires are problematic to manufacture en masse. out to solve the matter, zhou’s team took commercially accessible nanoparticles — small silicon spheres — and etched them the exact pores like the nanowires. the particles gathering similarly which can be created in any quantity desired.

though the silicon nanoparticle batteries nowadays last for barely 200 recharge cycles ( compared out to an average of 500 for graphite-based designs ), the team’s older silicon nanowire-based design lasted for up out to 2, 000 cycles, that was reported in nano lett last april.

additional development of one's nanoparticle design ought to boost the battery’s lifespan, zhou same.

“the straightforward technique we use may generate real affects battery applications within the whole close to future, ” zhou same.

future research from the cluster can specialize in finding a brand new cathode material with the use of a high capability that could combine well in the porous silicon nanowires and/or porous silicon nanoparticles to form a very redesigned battery.

the tasks was funded by usc viterbi.

Dual SIM Nokia LG

By Anak Ifu | At 3:08 pm | Label : , , , , , , | 0 Comments
nokia and lg electronics have each launched new phones that may handle 2 sim cards. providing dual-sim product has turned out to be increasingly vital in my last number of years. they actually permit users to actually get higher tariffs or switch between sims for personal or work use.

significantly utilizing a number of emerging markets -- india, for instance -- dual-sim support has turned out to be an absolute requirement currently, aforementioned geoff blaber, who leads mobile device research at ccs insight.

from nokia comes the series 40-based asha 310, that's the initial model coming from the company that combines slots for 2 sim cards with wi-fi for faster knowledge access.

the most sim card sits behind the battery, with the use of a slot obtain a second sim located upon the facet of one's phone for simple access, allowing users to actually switch the second card while not having to actually switch from the phone, according to actually nokia. the sim manager lets users assign profiles for up to actually 5 sim cards and define that card they actually wish to work with for messages or calls, text messages, and internet access, the corporate aforementioned.

the asha 310 additionally has got a 3-inch capacitive bit screen but a microsd memory card slot for additional memory. either a 2gb or 4gb card is included within the box.

the asha family has given nokia a boost whereas the corporate has struggled with sales of its windows phone-based lumia family. throughout the fourth quarter it sold 9. 3 million asha full bit phones, compared to actually 4. 4 million lumia smartphones.

the android camp is likewise obtaining upon the dual-sim bandwagon. from lg comes the optimus l7 ii, that additionally to 2 sim cards additionally has got a 4. 3-inch screen and an 8-megapixel camera. it's powered by a dual-core 1ghz processor, has 4gb of integrated storage but a microsd card slot.

just as the recently launched optimus lg pro, the optimus l7 ii has got a considerably bigger battery than its predecessor -- 2, 460mah versus 1, 700mah.

the nokia asha 310 will surely be on the market in asia, india, the center east, africa and brazil this quarter. it'll cost around $102 while not native taxes or any operator subsidies. the dual-sim version of one's optimus l7 ii can maintain sale in russia now, other then no pricing was announced.

the phones will surely be on show at mobile world congress, that starts in barcelona on feb. 25.
