Explore further “I first started thinking about ‘future radio,’ and the possibility of mapping every radio station to the pages of a book,” Watanabe told PhysOrg.com. “Listening to radio like reading a book was the initial idea or concept.”With Watanabe’s book, users can search and access content such as TV channels, digital radio stations, bookmarked Web sites, as well as photo, audio or movie files stored on a hard drive. While current search methods—such as multiple clicking or pressing buttons, graphical user interfaces, and excessive scrolling—can handle smaller amounts of data, they become more complex and time-consuming as the data increases. Books, on the other hand, are interactive, can contain large amounts of information—and don’t crash.“The main audience for this type of device is people who aren’t into technology,” Watanabe said. “I wanted to develop a UI [user interface] which does not change people’s natural, traditional behavior, like turning over the pages.”In this design, 0.8-mm-thick light dependant resistors (LDRs), which measure brightness, are attached to each page and the front and back covers. A peripheral interface controller (PIC) hidden in the back cover senses what page the book is open to (or if it’s closed) from the LDRs, and uses Bluetooth to wirelessly send the state of the book to the target device (e.g. TV or PC). The different states of the book have straightforward meanings: opening the book turns the device on, closing the book turns it off; turning the pages switches pre-set content (such as TV channels); and turning the book upside down mutes the device. Users can operate the book anywhere within about 15 feet from the target device.Watanabe has already used the device for several applications, including a TV remote control. To connect the remote control to the book, Watanabe “hacked” the remote using a PIC and relays, allowing him to switch the buttons on the remote by operating the book. He did the same thing with a digital radio control, digital photo viewer, and bookmarked Web sites.In the future, Watanabe plans to research how electronic paper might be used in the book. Electronic paper could enable even more options, while providing color images and flexible pages. For example, Watanabe hopes to prototype functions such as play, pause, rewind, etc. Also, the content is currently manually pre-set, and Watanabe plans to develop software to make this work easier.As simple and straightforward as the book browser is, the device also extends to the deeper modern concept of bridging the gap between the paper and electronic worlds.“I think paper gives a new interface to the digital world,” Watanabe said. “This bridging will fill the gap between people who aren’t into technology and the digital world.”Citation: Watanabe, Jun-ichiro. “A Device for Easily Browsing Various Content Using the Metaphor of Reading Poetry.” IEEE Transactions on Consumer Electronics, Vol. 53, No. 1, February 2007.Copyright 2007 PhysOrg.com.

Electric bicycle gets 60mile range with portable hydrogen fuel cell

first_imgSiGNa Chemistry’s range extender is shown on this Pedego® electric bicycle. Image credit: SiGNa and Pedego. Compared to advanced Li-ion batteries that have an energy density of about 65 Watt-hours per kilogram, SiGNa’s cartridges have an energy density of more than 1,000 Watt-hours per kilogram. The hydrogen cartridge produces up to 200 Watts of continuous power, and excess energy is stored in a Li-ion battery for climbing hills and energy-intensive acceleration.SiGNa Chemistry demonstrated the “range extender” power system at the Interbike International Trade Expo in Las Vegas at the end of last month. Although the company used the system on a Pedego® electric bicycle, the system is compatible with most other electric bicycle models. Since the fuel cells weigh just 1.5 pounds and are reusable, cyclists can easily replace them on long rides if they have more than one, eliminating the need to stop and recharge.The hydrogen system is also safe, as the hydrogen is produced at just 50% of the pressure of a soda can. The system’s only emission is water vapor, and sodium silicate, an environmentally safe byproduct of sodium silicide, is fully contained in the cartridge.According to SiGNa President and CEO Michael Lefenfeld, the company plans to take this technology beyond bicycles to serve as a primary or back-up power source for other transportation applications. Other applications include generators, lawn mowers, golf carts, consumer electronics, and any electric application that uses 1 W to 1 kW of power.SiGNa is currently taking pre-orders for the cartridges (no price listed), and plans to have the product commercially available next summer.

The New York City-based company has developed a cartridge containing sodium silicide, a stable metal powder. When the powder comes in contact with water (including polluted water, sea water, and urine), it instantly produces hydrogen, and the hydrogen is then converted into electricity. According to the company, one cartridge can power a bicycle for a range of up to 60 miles without pedaling. Sanyo rolls electric bicycles into US market © 2010 PhysOrg.comlast_img read more

Bacteria species part of Curiosity baggage on Mars

This is the finding of a study titled “Identification and Survival of Isolates Collected from the Mars Rover, Curiosity.” The scientists who worked on the study, from the University of Idaho, Jet Propulsion Lab at CalTech in Pasadena, Idaho State University, South Dakota School of Mines and Technology, and Colby College, presented their findings on Monday to the American Society for Microbiology meeting in Boston. Reporting on this project, Nature News said their study is the first to examine the entire archive of microbes collected from Curiosity. The study is not only interesting for the number of strains identified but also for observations about their resistance. Results from the study can now provide details about the microbes that inhabit the surfaces of spacecraft after microbial reduction.Nature News, commenting on the findings, referred to “a surprising number” resisting extreme temperatures and damage caused by ultraviolet-C radiation, the most potentially harmful type.In their presentation abstract, the authors explained how organisms were collected during MSL’s planetary protection implementation campaign. (MSL refers to the Mars Science Laboratory.). Isolates were identified and characterized using standard culturing and molecular techniques. Results showed 62% of the 377 organisms identified were related to members of the Bacillus genus while 31% belonged to non-spore-forming genera. Many isolates showed resistance to desiccation (78%), and UVC radiation and 94% of the isolates could grow in the presence of elevated salt conditions (≥10% NaCl) and 35% at low temperatures (4C), while 11% of isolates could survive under multiple extreme conditions.last_img read more

When Zen dance came to Capital

first_imgArtistes from India and South Korea recently combined martial arts forms with traditional dance techniques to showcase a unique art form that was both entertaining and healing, on the sidelines of a three-day international seminar, a part of Asia Project, in the Capital.Among the art forms showcased were Zen dance and Son Mudo from South Korea and Thangta, the martial arts form of Manipur.‘I developed this art form (Zen dance) in New York in 1972. I combined meditation and dance and created a dance meditation technique,’ said Sun Ock Lee, who performed with partner Won Il Lee at the IIC auditorium. According to Sun, the goal of both martial arts as well as meditation is to bring the mind and the body together and to free life from suffering. Also Read – ‘Playing Jojo was emotionally exhausting’‘But before you can achieve that stage through this technique (Zen dance), you can increase your concentration, creativity and reduce stress level,’ she said.On Son Mudo, Sun Ock Lee said: ‘This art form was created by my teacher 85 years ago. It is all about harnessing the power of the mind and making the body follow the mind. It is very creative.’‘This art form uses the Yin and Yang principle of Chinese, Korean and Japanese philosophy. A lot of opposites are used in it,’ she added. While Zen Dance and Son Mudo were popularised by Sun Ock Lee in Europe and America, she has been working for the last few years to popularise it across Asia.The artiste also displayed Buddhist mudras (hand and wrist movements). ‘They are based on Tantric or Vajrayana Buddhism which was brought to Korea in the fourth century. There is a distinct difference between Buddhist mudras and the Hindu mudras’ Zen Dance and Son Mudo, according to Sun Ock Lee, also have powers of healing.last_img read more

Bengal eyeing twofold hike in export growth rate by 2021 Amit

first_imgKolkata: Bengal government has set a target of doubling the export growth rate of the state within 2021, said Industry, Commerce and Enterprise minister Amit Mitra on Monday.He was addressing a workshop with the exporters, industries and various other stakeholders at a city hotel to accelerate the process of export promotion from the state. Despite some issues relating to the non-payment of refunds to the exporters, particularly to the small-scale ones, the state government has been able to achieve export growth rate of 11.17 percent last year. Also Read – Heavy rain hits traffic, flightsMitra said that there was an export of 8.23 billion US dollars from Bengal in the financial year 2016-17, which has gone up to 9.15 billion US dollars in 2017-18. Products worth around Rs 62,000 crore have been exported from the state in 2017-18.The Bengal government is taking all possible steps to double the figure in the next three years.”We have achieved 11.17 percent growth rate in exports, which is pretty high among all other states. It was around 10 percent last year. The export growth rate of the country according to CAGR remained at 6.01 percent for a period from 2007-08 up to 2016-17. The overall export that stands at Rs 62,000 will be doubled in the next three years,” Mitra said. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedAccording to the minister, an information centre will be set up jointly by the West Bengal Industrial Development Corporation (WBIDC) and the MSME department, to disseminate information relating to the exports and various schemes.There are many schemes which the exporters do not know. The exporters will get to know the details about the schemes from these centres.An export cell will be set up at the district industrial centres, so that people interested in exports can gather information relating to it. Altogether 80 officers from industry and MSME sectors will be given training at the Institute of Foreign Trade in Kolkata, for a period of one month from July 5. Among the total number of officers, around 60 would be from the MSME department, while the rest would be from industries. After returning to the district industrial centres, these officers will give answer to the quarries of the potential exports. They will be made aware on how the documentation is done.Mitra also said that a dyeing centre has come up at Nabadwip, which will meet global standards so that the exporters from the state would no longer face any problems during the certification. Around 50,000 weavers would also be benefitted from the project.There was an overall export of 825 million US dollar of iron and steel from Bengal in 2016-17 and the target is to reach up to 1,500 million US dollar within the next three years.While gold and other precious material export remained at 711 million US dollar, with a target of 1,200 million US dollar.The Bengal government has developed a major infrastructure by setting up a Gems and Jewellery Park at Ankurhati in Domjur in this regard. In the leather sector, export stands at 687 million dollar and the target is to reach 1,500 million dollar.Asia’s biggest leather park has come up at Bantala. The state government has allotted a Rs 400 crore investment in Bantala. Marine products and petroleum products have seen a rise in the export.The minister also reminded that apart from airport and sea port, a land port should also be set up for accelerating the exports. In case of fresh vegetables, the exporters were facing problems as they have to export the products through Vizag port. The issue would be taken up with the Union commerce minister.Sanjay Budhia, managing director, PATTON Group, who was present at the programme, said: “We thank minister Mitra and his colleagues for this much needed initiative and the first of its kind ‘Workshop on Promoting Exports from West Bengal’, involving and interacting with exporters across all sections. Today’s programme again reinforced that Bengal means business and exports is one the key factors to create employment and economic activity.”last_img read more

Celebrating fashion confluence

first_imgPicking up a piece of cloth and creating a visionary design,  by a designer, who too like an artist puts in all the imagination that one has, is a treat for one to witness.  The imagination comes alive and it becomes a proud moment for the artist when he is able to celebrate and showacse his/her collection. Craft revivalist and textile conservationist Madhu Jain hosted an evening to introduce her Spring-Summer collection on Thursday at ‘Ogaan’ in the national Capital.  Maneka Gandhi, Union Cabinet Minister for Women & Child Development, inaugurated the collection. Some of the prominent guests spotted at the event were Designer Poonam Bhagat, Tikka Shatrujit Singh, Ambika Shukla, Neelam Pratap Rudy, Shovana Narayan, Alpana Gujral, Ruchi Malhotra Makhni, and many more. Also Read – ‘Playing Jojo was emotionally exhausting’Madhu, whose formidable reputation has been built on promoting indigenous forms of textile weaving and designs, unveils her vibrant new collection. This time she showcases her brand-new Uzbek-inspired Ikats, alongside a retrospective of her signature Andhra Pradesh and Odisha Ikat styles into which she has infused the Buddhist Mandala design inputs from the textile traditions of Thailand. “My fresh collection showcases a confluence of two cultures—Indian and Uzbek—that share so much in common. Seeing the unifying threads in the traditional weaves of two different regions is something that enthuses and challenges me. I then set about seeing how I can amalgamate the beauty in each to produce a totally new weave that nonetheless stays true to the distinctiveness of the individual cultures. In Andhra, for instance, Ikat fabric is produced on pit looms, and semi-circular frames are used in the preparation of warp and weft.  Also Read – Leslie doing new comedy special with NetflixThe design sensibility leans towards geometricals. In Odisha, on the other hand, Ikat is inspired by temple motifs and also by nature. So, you will notice parrots, flowers, elephants, and deer. And also, Navagunjara, an animal, which is considered to be an incarnation of Vishnu, you will find incorporated in Odisha’s traditional Pattachitra paintings. I took both sets of elements and combined them to come up with contemporary weaves that remain rooted in the traditional forms,” says Madhu.For this collection, Madhu has worked with master weavers to create a convergence of two distinct styles with a colour palette that is largely influenced by Indigo. Atisha Pratap Singh is the face of Madhu Jain’s Spring-Summer line.last_img read more

Fire breaks out at Kolkata Leather Complex tannery two injured

first_imgKolkata: A fire broke out at a tannery in Kolkata Leather Complex area on Wednesday afternoon. Two persons sustained burn injuries due to this and one person among them is seriously injured. Both are admitted to a hospital near Ruby crossing. The fire was extinguished after almost two hours.Sources informed that at around 12:30 pm on Wednesday, the locals noticed smoke coming out of a tannery at plot number 163 of Kolkata Leather Complex.Immediately, nearby people started shouting in order to alert the persons working inside. Some of the workers rushed out of the building but two persons identified as Rinku Mondal and Sagar Das somehow got trapped inside. Fire brigade and police were informed. Within a short period of time, four fire tenders reached the spot and started the rescue operation while a few firefighters went inside with precautionary measures to recover the duo trapped there. Within a few minutes, both the injured persons were recovered and sent to hospital. According to the police, Mondal has been admitted with 80 percent burn injury and Das suffered minor burn injuries. Also Read – Rain batters Kolkata, cripples normal lifeAccording to fire brigade officials, as the tannery was filled with leather, fire spread very quickly and firefighters faced difficulties because of wind while dousing the flames. Later, two more fire tenders were pressed into action. It got extinguished around 2:45 pm.Though it is suspected that the fire occurred due to a short circuit but police and fire brigade officials are yet to ascertain. To mark the cause, fire brigade officials may visit the tannery on Thursday.Apart from the existingfire fighters, Disaster management Group personnel of Kolkata Police also worked relentlessly to douse the flames. It will be investigated whether the fire fighting equipment were in a working condition.last_img read more

Cataract risk in women

first_imgWomen in India who cook using fuels such as wood, crop residues, kerosene and dried dung are nearly 50 per cent more likely to have cataracts than those who use clean fuels such as gas, new research warns. The study, believed to be the largest such, was conducted by the All India Institute for Medical Sciences (AIIMS), Aravind Eye Hospitals and London School of Hygiene & Tropical Medicine. “Our results reinforce the documented risks of biomass fuels on other health conditions in India and highlight the need for the rapid development of affordable, clean cooking fuels,” said study co-author RD Ravindran, the chairperson, Aravind Eye Care System.The population-based study involved nearly 6,000 people aged 60 and over from randomly chosen rural villages and small towns in India.  Also Read – ‘Playing Jojo was emotionally exhausting’Participants were interviewed at home on their use of cooking fuel over their adult life, and on a range of socioeconomic and lifestyle factors. After taking into account other risk factors including indicators of poor nutrition, sun exposure, smoking and chewing tobacco, the researchers found that women who cooked with biomass fuels were 46 per cent more likely to have nuclear cataracts compared to those who used gas. Furthermore, the researchers found that cataracts were more likely to affect women when the length of the time women had used biomass fuels increases. That is from 50 per cent more likely for 20 years use rising to 90 per cent after 30 years. “Our study provides the strongest evidence yet of an association with adult lifetime exposure to biomass fuels and cataracts,” professor Astrid Fletcher from the London School of Hygiene & Tropical Medicine who co-ordinated the study said. Also Read – Leslie doing new comedy special with Netflix“This was only found in women, probably because cooking was almost only done by women using stoves without chimneys, exposing them directly to smoke. Unexpectedly we also found that women who cooked with kerosene were more likely to have cataracts,” Fletcher noted. The study was published in the journal Environmental Health Perspectives.Biomass cooking fuels are particularly common in India, especially in poorer communities, as they are generally cheap and easily accessible. Recent estimates suggest that 83 per cent of rural households and 19 per cent of urban households in India use them. However, they are typically burnt in open stoves exposing households to high levels of health damaging pollutants including small respirable particulates. It is thought these may impair the eye’s defence system, accelerating the clouding of the lens leading to cataract.last_img read more

2 women held for assaulting woman inside train at Sonarpur

first_imgKOLKATA: A woman was allegedly beaten up by two co-passengers in a local train at Sonarpur. Later, Government Railway Police (GRP) arrested the duo. The complainant alleged that on Monday morning, she was taking her daughter to school. Around 10:30 am, when the train was about to enter Sonarpur station, the complainant tried to move forward as she had to get down. Two women were standing near the gate. As her way was blocked, the complainant asked them to provide space for them to pass. Hearing this, both the women used abusive language and asked her to make space for herself. When she tried to move forward, the complainant came in contact with one of the women standing there, which made the duo furious. They started beating up the complainant and pulled her hair. Though none of the co-passengers came to her rescue, some of them screamed as the train had already entered the station. Hearing their screams, some GRP personnel went to the compartment and were informed about the incident. Immediately, both the accused were detained. The complainant was taken to a local hospital and was treated and discharged. Later, she lodged a complaint with the Sonarpur GRP, following which the women were arrested.last_img read more
