Space boomerangs

07 Mar 2008

Do boomerangs return when thrown in zero-gravity? Japanese astronaut Takao Doi will soon find out by throwing some around inside the International Space Station.

When the Space Shuttle Endeavour launches on March 11, Doi will be carrying a pair of paper boomerangs presented by Yasuhiro Togai, a 2006 world boomerang champion and space enthusiast from Osaka. Togai, who long wondered how boomerangs would fly without the downward pull of gravity, suggested Doi conduct boomerang experiments in space after they met several years ago. Doi agreed, and Togai taught him how to throw. Togai believes the space boomerangs will spiral up and away without returning, but he says he is looking forward to the results.

Cyber Goggles: High-tech memory aid

04 Mar 2008

Smart goggles --

Researchers at the University of Tokyo have developed a smart video goggle system that records everything the wearer looks at, recognizes and assigns names to objects that appear in the video, and creates an easily searchable database of the recorded footage. Designed to function as a high-tech memory aid, these "Cyber Goggles" promise to make the act of losing your keys a thing of the past, according to head researcher professor Tatsuya Harada.

Cyber Goggles are equipped with a compact camera that feeds video to a computer worn on the user's back. The computer records the footage and relies on ultrahigh-speed image recognition processing software to analyze, name and file the objects that appear in the video. Later, when the user types in a keyword to search for a particular item, the corresponding video plays on a tiny LCD screen attached to the right-side lens, helping the user remember the location of the item in question.

In a demonstration at the University of Tokyo last week, 60 everyday items -- including a potted begonia, CD, hammer and cellphone -- were programmed into the Cyber Goggle memory. As the demonstrator walked around the room viewing and recording the various objects, the names of the items appeared on the goggle screen. The demonstrator was then able to do a search for the various items and retrieve the corresponding video.

In addition to functioning as a memory aid for the elderly, Cyber Goggles have a number of other potential uses, says professor Harada. For example, the image recognition processing technology can be used to sift through enormous amounts of video in search of specific images. It might also help in the development of robots with human-like abilities, he says.

Japan’s crying Virgin Mary statue

03 Mar 2008

Japan's crying Virgin Mary statue --

This 1979 photograph shows the teary-eyed Our Lady of Akita statue at the Seitai Hoshikai (The Institute of the Handmaids of the Holy Eucharist) convent in Akita prefecture. In January 1975, 12 years after a local sculptor carved the statue from the wood of a Japanese Judas tree, it began to cry. Over the next 6 years, around 2,000 witnesses reported seeing the statue weep 101 times. The quantity and frequency of the tears varied each time -- sometimes the statue cried a few times per day, and sometimes it went months, and even years, without crying. The statue, which is still housed at the Akita convent, shed its final tears in September 1981.

Video: Cloud streets

27 Feb 2008

Cloud streets --

This video -- a follow-up to a previous post about strange cloud formations seen over the Sea of Okhotsk last summer -- provides a rare close-up bird's-eye view of cloud streets, which are created when convection currents cut low-lying cumulus into long, clean strips. According to the video narration, these clouds floated just over the sea surface, stood 300 meters tall and stretched for over 100 kilometers.

Kirichimpo: Phallic promotional mascot

26 Feb 2008

Kirichimpo --

Fresh on the Akita prefecture promotional gimmick scene is a unique and decidedly male mascot modeled after the region's famed kiritampo grilled rice cake skewers. "Kirichimpo" (kiri means "cut" and chimpo is slang for the male organ), a lovey-eyed kiritampo stick with a conspicuous protuberance dangling from its lower end, is the brainchild of Fruru Co., Ltd., an Akita-based souvenir designer and wholesaler.

Mamemokkori and Marimokkori -- The company came up with the idea for Kirichimpo last year after witnessing the far-reaching success of Marimokkori, a happy, well-endowed green monster mascot from Hokkaido, whose name is a play on the words marimo (a type of giant algae ball found in Lake Akan) and mokkori ("erection"). Marimokkori's popularity extends far beyond Hokkaido's shores, to as far away as Chiba, the home of his younger peanut-headed cousin named Mamemokkori (mame means "bean"), and Tokyo, where mounds of the popular Marimokkori can be found inside UFO Catcher claw vending machines at game centers.

While Kirichimpo has yet to rise to Marimokkori status, it appears to be enjoying a measure of success. Last year's initial shipment of 6,000 Kirichimpo keychains sold out in a matter of months. And with demand still strong, the company is rolling out a Kirichimpo ear pick and other new gimmicks, which are soon to appear at souvenir shops and train stations throughout Akita prefecture at a price of 350 yen ($3) each.

Vintage anime: Evil Mickey Mouse invasion!

25 Feb 2008

1930's war anime --

"Toy Box Series, Episode 3: Picture Book 1936" (Omocha-Bako Series, Dai-3-Wa: Ehon 1936) is a 1934 propaganda-ish film about a future (1936) conflict started by a swarm of evil, bat-riding Mickey Mouse clones that descend on a tiny island inhabited by peace-loving dolls and cats (including a Felix lookalike). Overwhelmed by the attack, the desperate island residents bang on the cover of a large picture book to enlist the help of Momotaro, Urashima Taro (the Japanese version of Rip Van Winkle), and other traditional fairy tale heroes and characters. After Urashima Taro uses his famous "mystery box" to turn the big Mickey into a decrepit old fogey, Hanasaka Jiisan makes the cherry trees bloom and the cats and dolls celebrate by dancing to "Tokyo Ondo" (an old Japanese folk song). The soundtrack also includes renditions of the Momotaro song and Gunkan March ("Warship March"), a song that is nowadays typically played at pachinko parlors.

Laughometer measures aH

23 Feb 2008

Laugh measurement system -- For those who believe laughter is the best medicine, now there is a way to measure the dosage. Researchers at Kansai University have developed a machine that can scientifically measure the quantity of a person's laughter, as well as distinguish between the real and the fake.

The laughter measurement system, which the researchers say will help scientists conduct more detailed research into the physiological effects of laughter on the immune system, relies on a series of electrode sensors that monitor the tiny amounts of bioelectricity generated by certain muscles that flex when you chuckle. The sensors, which attach to a person's cheeks, chest and abdomen, take 3,000 measurements per second. Sensor data is relayed to a computer, where it is analyzed by special software that determines the nature of the laugh and assigns a numerical score based on the quantity.

The laughter quantity is expressed in terms of "aH" -- a unit of measurement developed by the research team. According to chief researcher Yoji Kimura, a Kansai University professor, 1 second of explosive laughter amounts to 5 aH.

The system distinguishes between real and fake laughter by closely monitoring the movement of the diaphragm -- the thin sheet of muscle extending across the bottom of the rib cage, which separates the chest organs from those of the abdomen. According to Kimura, the diaphragm does not vibrate significantly when a person pretends to laugh, even when the person's voice and facial expression appear genuine. On the other hand, when one laughs at something they truly find funny, the diaphragm generates 2 to 5 distinct vibrational waves per second.

At Kansai University on February 21, the researchers publicly demonstrated the system by measuring the laughter of a 30-something-year-old woman and her 5-year-old daughter as they watched a performance by Yoshimoto comedians. The mother, who apparently found no humor in the comedy routine, experienced only slightly more than 0 aH of laughter, while her amused daughter experienced a hearty 42 aH.

The researchers, who spent over a year developing the system, are aiming to create a portable version of the system for use in health and entertainment devices.

Robot buoy hunts down spilled oil

21 Feb 2008

SOTAB -- As long as oil is transported by sea, accidental spills will remain a threat to the marine environment. When an oil spill occurs, the cleanup response must be quick in order to minimize the environmental and economic impact. To help speed up the response, researchers at Osaka University are developing an autonomous marine robot that can track down spilled oil and provide real-time location data.

SOTAB 1 (Spilled Oil Tracking Autonomous Buoy 1) is a 110-kilogram (243 lb.) GPS-equipped robot that measures 2.72 meters (9 ft.) from top to bottom and 27 centimeters (11 in.) in diameter. It has imaging sensors that can spot floating globs of oil from a distance, as well as viscosity sensors that detect the presence of oil, and it includes a wind monitor, depth meter and water thermometer. When multiple robots are dropped into the water at regular intervals around an oil spill, they can provide a wealth of valuable data to cleanup crews and allow them to monitor a wide area.

Once in the water, SOTAB 1 begins searching for oil by reducing its buoyancy and diving underwater, where it trains its imaging sensors back up at the surface. When the robot sees something that looks like oil, it readjusts its buoyancy and floats back to the surface, using 4 fins to steer toward the oil slick. It then takes water samples and determines how much oil is present. As SOTAB 1 follows the oil around, it sends back real-time data about its location and the surrounding meteorological and oceanographic conditions.

Head researcher Naomi Kato, an underwater robotics engineering professor at Osaka University, says SOTAB 1 is still in the development phase, but he hopes to see it become commercially available in 2 to 3 years.

"We want to get the weight under 30 kilograms and extend the battery life to about 3 to 4 weeks," says Kato, who began working on the robot in 2006. "We would one day like to see these robots become standard equipment on oil tankers."

Fitness machines with finger vein readers

19 Feb 2008

medimo --

In recent years, Hitachi's finger vein authentication technology, which identifies individuals by the unique pattern of blood vessels inside their fingers, has helped beef up the security of devices ranging from ATMs and cardless payment systems to computers and automobile ignition systems. Now this biometric technology is heading to the gym.

IT company Fukui Computer has unveiled a new line of networked exercise machines, called "medimo," that are equipped with Hitachi finger vein readers. When users identify themselves with a simple press of the finger, the machines respond by automatically adjusting the weight resistance and seat position based on the user's previously set preferences.

The machines also connect to a remote server to retrieve the user's personal exercise data -- including previous exercise records and stats, training regimens and calorie consumption data -- which shows up on a touch-screen display. Users can then do their workouts based on this data, which is updated each time a machine is used, or personal trainers can refer to it when providing exercise advice.

Fukui, who unveiled the 12 new medimo machines on February 18, plans to begin selling them on April 1 for about 1.8 million yen ($17,000) each. The company is targeting fitness gyms, hospitals and welfare facilities, and is expecting to sell 2,000 machines over the next 3 years.
