TP students present innovations at exhibition

Label:





SINGAPORE: More than 60 nifty inventions were presented at this year's Engineering Project Show at Temasek Polytechnic on Monday.

Some ideas included a baby pram that can function as a high chair and a tray return system. The ideas are the final-year projects of the polytechnic's engineering students.

Five students created an "Ah Long" detector, which could be attached to front doors to deter loansharks from vandalising.

When paint is poured over the door, the system detects the paint fumes and sends the information and a screen shot of the culprit to relevant authorities.

The project is thought to be the first in the market, and was created by students Chelsea Koh, Nur Syairah Baharuddin, B Nisha, Ryan Fan and Haris Fadhillah Ismail.

The team said they were initially looking at creating a bomb detection system, until the Singapore Police Force suggested the paint detection idea.

Ms Syairah said: "The rate of (crimes committed by loansharks) is increasing in Singapore, and it also benefits the Singapore Police Force to attend to the matter in a shorter period of time, thus it's a very important job for us to help them to make their task even easier."

Another timely creation at the show was a coin-operated tray return system.

The team behind the idea was inspired by a supermarket's trolley-lock system. Users slot a coin into the trays, slide them out of the tray racks. They would then collect their food, and slide the the trays into specially-designed tables.

Not returning the tray after a meal would mean forfeiting the coin.

The team of three, comprising Sadish Rao, Effendy Parman and Chen I Chieh, said the idea came about following a tray return campaign conducted by the National Environment Agency (NEA) in 2012.

Mr Rao said: "During the peak hours, there are a lot of customers, and cleaners can't cope with the cleaning. Sometimes when we want to go and eat, we find a table to sit down, but nobody clears the utensils and trays. With this system, every table will be clean and we'll have a lot of space to sit down and we won't have this kind of problems to face in the future."

The project has been nominated for the Tan Kah Kee Young Inventors Award. Mr Rao said it cost the team about S$250 to make one section that accommodates four trays. Each tray with the attached lock system costs S$40. His team is in touch with NEA on the project.

The Engineering Project Show is open to the public till Tuesday.

HTC Q4 profit, sales plunge amid holiday crush

Label:


The Droid DNA didn't help HTC's results in the fourth quarter.

LAS VEGAS--Apparently, the worst isn't over for HTC.


The Taiwanese company reported that its fourth-quarter profit fell more than 90 percent to 1 billion Taiwanese dollars ($34 million) from more than 10 billion Taiwanese dollars a year ago. Sales fell roughly 40 percent to 60 billion Taiwanese dollars.



The poor results mark the lowest profit in eight years for HTC, according to Bloomberg, and further illustrates the difficult position that it continues to be in. The results come despite having a flagship smartphone at Verizon Wireless in the Droid DNA, as well as the marquee smartphone for Windows Phone 8 in the Windows Phone 8X.


HTC has a virtual non-presence at this year's Consumer Electronics Show, which is expected to be light on mobile news.


They also come as HTC CEO Peter Chou vowed that HTC will have a better year in 2013, blaming some of the weakness on the lack of marketing support.


The company, however, finds itself outgunned by larger companies such as Apple and Samsung Electronics, which have much larger war chests to draw upon for their marketing campaign. While HTC was an early darling of the
Android community, much of the buzz has since shifted over to Samsung.


HTC began to show cracks about a year ago, when its 2011 fourth-quarter results disappointed for the first time. Since then HTC has shown consistent year-over-year declines as consumers move away from its smartphone products.


Industry observers, meanwhile, struggle to see how HTC can get back to its lofty position given its relatively limited resources. The company has attempted to compensate by partnering more closely with allies such as the carriers and with Microsoft, but that hasn't yet paid off.


HTC isn't in as bad a position as some of its peers, including former heavy hitters such as LG and Nokia. Both those companies, and several other handset makers, continue to post losses.


It remains to be seen whether HTC and Chou will make good on his vow to turn things around. The last year has shown that even good phones get ignored without the proper support.

Silent Skype calls can hide secret messages

Label:








































Got a secret message to send? Say it with silence. A new technique can embed secret data during a phone call on Skype. "There are concerns that Skype calls can be intercepted and analysed," says Wojciech Mazurczyk at the Institute of Telecommunications in Warsaw, Poland. So his team's SkypeHide system lets users hide extra, non-chat messages during a call.












Mazurczyk and his colleagues Maciej Karaś and Krysztof Szczypiorski analysed Skype data traffic during calls and discovered an opportunity in the way Skype "transmits" silence. Rather than send no data between spoken words, Skype sends 70-bit-long data packets instead of the 130-bit ones that carry speech.












The team hijacks these silence packets, injecting encrypted message data into some of them. The Skype receiver simply ignores the secret-message data, but it can nevertheless be decoded at the other end, the team has found. "The secret data is indistinguishable from silence-period traffic, so detection of SkypeHide is very difficult," says Mazurczyk. They found they could transmit secret text, audio or video during Skype calls at a rate of almost 1 kilobit per second alongside phone calls.












The team aims to present SkypeHide at a steganography conference in Montpellier, France, in June.

WP hopes to raise S$1.5m to purchase headquarters

Label:





SINGAPORE: The opposition Workers' Party (WP) is hoping to raise S$1.5 million for the purchase of its own headquarters.

The party's secretary-general Low Thia Khiang and chairman Sylvia Lim said this at the party's first musical concert, titled "Brick in Blue".

Ms Lim said since the 2011 general election, the party has raised some S$500,000.

The money came from monthly contributions from its elected Members of Parliament, as well as private donations from friends and acquaintances.

The rest of the money, she said, will be raised through public donations.

Ms Lim said the S$1.5 million will be used for the down payment of the property, while the balance of the purchase price will be financed through a loan.

Speaking to reporters during the intermission of the musical, Mr Low said the party has yet to find a suitable property.

He said proceeds from the concert will go towards the party's building fund.

The party is currently renting an office along Syed Alwi Road.

Nvidia at 2013 CES: Join us Sunday, 8 p.m. PT (live blog)

Label:

Nvidia starts the 2013 International CES early with a press conference at 8 p.m. PT (11 p.m. ET) on Sunday, Jan. 6, and CNET will be there to cover it live. We'll have a live video stream, along with a blog full of news and analysis, as it happens.

You can tune into the blog and video stream here:

CNET's live coverage of Nvidia's 2013 CES press conference

Nvidia has been pretty quiet about any possible announcements at
CES, but the graphics chipmaker is likely to talk up Tegra, its processor for mobile devices. The company has had some success getting the chip into
tablets over the past year, but it continues to struggle in smartphones. Nvidia is counting on its new integrated processor, which combines the apps processor with the wireless connectivity on the same piece of silicon, to change that.

An alleged leak about Nvidia's Tegra 4 from last month showed 72 graphics cores, six times as many as those found in the current-generation Tegra 3. That many cores would mean substantially improved performance for smartphones, tablets, and other devices.

Gun Show Near Newtown Goes on Despite Anger

Label:












A little more than 40 miles from Sandy Hook Elementary School, where last month 20 first graders and six staff members were massacred, gun dealers and collectors alike ignored calls to cancel a gun show, and gathered for business in Stamford, Conn.


Four other gun shows with an hour of Newtown, Conn., recently cancelled their events in the wake of the shootings, when 20-year-old Adam Lanza broke in to the elementary school with a semi-automatic assault rifle and three other guns.


The organizers in Stamford emphasized their show only displayed antique and collectible guns, not military style assault weapons like the one used by Lanza in Sandy Hook.


Still, Stamford Mayor Michael Pavia had called for the show to close its doors, calling it "insensitive" to hold so close to the murders.


Gun show participant Sandy Batchelor said he wasn't sure about whether going ahead with the show was "insensitive," but said the shooter should be blamed, not the weapons he used.


"I don't have a solid opinion on [whether it is insensitive]," Batchelor said. "I'm not for or against it. I would defend it by saying it wasnt the gun."


In nearby Waterbury, the community cancelled a show scheduled for this weekend.


"I felt that the timing of the gun show so close to that tragic event would be in bad taste," Waterbury Police Chief Chief Michael J. Gugliotti said.












National Rifle Association News Conference Interrupted by Protesters Watch Video





Gugliotti has halted permits for gun shows, saying he was concerned about firearms changing hands that might one day be used in a mass shooting.


Across the state line in White Plains, N.Y, Executive Rob Astorino also canceled a show, three years after ending a had that had been in place since the 1999 Columbine High School shooting in Colorado. He said he felt the show would be inappropriate now.


But across the country, farther away from Connecticut, attendance at gun shows is spiking, and some stores report they can hardly keep weapons on their shelves with some buyers fearful of that the federal government will soon increase restrictions on gun sales and possibly ban assault weapons altogether.


"We sold 50-some rifles in days," said Jonathan O'Connor, store manager of Gun Envy in Minnesota.


President Obama said after the Sandy Hook shooting that addressing gun violence would be one of his priorities and Rep. Nancy Pelosi, D-Calif., said she would introduce an assault weapons ban this month.


But it is not just traditional advocates of gun control that have said their need to be changes in gun laws since the horrific school shooting.


Republican Sen. Kay Bailey Hutchison of Texas and Virginia Sen. Mark Warner, a Democrat but a long-time opponent of gun control who like Hutchison has received an A rating from the NRA, have both come out in support of strengthening gun laws.


In Stamford, gun dealer Stuart English said participants at the gun show there are doing nothing wrong.


"I have to make a living. Life goes on," gun dealer Stuart English said.


ABC News asked English, what he thought about the mayor of Stamford calling the show "insensitive."


"He's wrong," English said. "This is a private thing he shouldn't be expressing his opinion on."

Five suspected terrorists killed in Indonesia: police

Label:





JAKARTA: Five suspected terrorists were killed in raids on militant camps in eastern Indonesia in the latest in a series of anti-terror operations, police said on Saturday.

National police spokesman Boy Rafli Amar said the raids took place late Friday and Saturday morning on two separate militant training camps in West Nusa Tenggara province.

"Police were forced to open fire as they (the militants) have explosive material. They used the locations to assemble bombs," the spokesman said, adding that five pipe-bombs and materials to make explosive devices such as nitrate urea powder, scores of nails and batteries were seized during the operations.

The raids came after police on Friday killed two suspected militants carrying a handgun and grenades, and arrested four others, in Makassar, capital of South Sulawesi province.

"This is part of the terror group in Poso," Amar said of the latest raids, referring to a restive district in Central Sulawesi province known for being a hotbed of extremism, where militants run a training camp and have been involved in several police killings.

Police had said the group was led by the country's most wanted terror suspect, Santoso, who trained groups of young militants to launch guerrilla attacks against security forces.

Police have beefed up security in the Poso region since late last year after two police officers investigating the camp were found dead and buried in a hole with their throats slit, and several small bomb plots were subsequently foiled.

Indonesia was rocked by a series of deadly terror attacks targeted at Westerners over last decade, with most -- including the 2002 Bali bombings that killed 202 people -- blamed on the Al-Qaeda-linked group Jemaah Islamiyah.

But a crackdown on terrorism has weakened key militant groups and only low-impact attacks have been carried out in recent years by networks targeting law enforcement officers.
