Panasonic’s device is among a small but growing number of exoskeletons available commercially—less fantastic and more cumbersome versions of a technology that’s been a staple of science fiction for some time. Though they have mainly been tested in medical and military settings, the technology is starting to move beyond these use niches, and it could make a difference for many manual laborers, especially as the workforce ages.
“We expect that exoskeletons, or power-assist suits, will be widely used in people’s lives in 15 years,” says Panasonic spokesperson Mio Yamanaka, who is based in Osaka, Japan. “We expect that they will be used for tasks that require physical strength, such as moving things and making deliveries, public works, construction, agriculture, and forestry.”

Stokowski was not only one of the world’s foremost conductors; he was a technology enthusiast who firmly believed that technology could contribute to the dissemination and spread of classical music. Stokowski and his orchestra made many acoustic phonograph recordings between 1917 and 1924, and were in 1925 among the first to make an Orthophonic recording through the then-new electrical recording system licensed by the Victor Company from AT&T. He also arranged to have much of the Philadelphia Orchestra’s 1929-1930 season broadcast nationally over the NBC radio network. But he was universally unhappy with the quality of these recordings or broadcasts.
Bell Labs and its predecessor, the Western Electric Engineering Department, had been studying ways to improve the transmission, recording and reproduction of sound since the 1910s as a central part of its mission to perfect the quality of sound for the telephone network. To do so, the researchers wanted to record telephone transmissions. But the phonograph of the day was an acoustic/mechanical device. There was no electricity; and thus no way to directly couple the recording equipment to the telephone. Moreover, the frequency response was limited and uneven.
A team led by Joseph Maxfield solved the problem by inventing a system for electrical recording. AT&T then licensed the new technology to the recording industry. Victor began issuing electrical “Orthophonic” records in 1925. The improvement in sound astonished listeners. Company researchers soon coupled electrical recording to silent movies; the result was The Jazz Singer and Hollywood’s adoption of sound.
Bell Labs continued to work on improving the quality of recorded sound. A team led by AIEE Fellow Halsey Frederick invented new recording techniques, including a moving coil recording arm with a diamond or sapphire recording stylus that tracked a groove vertically (hill and dale) rather than laterally, and with a much smaller force. This provided greater dynamic range and less noise then a conventional recording. Alongside this they devised an improved method of preparing masters from the original wax recording; and gold sputtering, which coated the etched wax with a one-molecule layer of gold, which in turn could be electroplated with copper to produce a surface from which stamping masters for records could be made. Their new system provided a frequency response up to 10,000 Hz (up from 6000Hz) with reduced surface noise and an improved 60 dB dynamic range.
Electric lighting had been around since Davy's arc lamp in 1809. It took seventy years for Edison to patent the first really practical light. In the same year an engraving appeared of a portable electric light apparatus from Marhsall, Sons & Co. in England. The generator is on the two-wheeled assembly powered by a six horsepower steam engine. The claim was it only took an hour to put into operation and produced 6,000 candle power.
The interested reader can make some assumptions for lumens/sr with a common candle being roughly 1cd and check out the efficiency:-)
We knew the world would not be the same. A few people laughed, a few people cried, most people were silent. I remembered the line from the Hindu scripture, the Bhagavad-Gita. Vishnu is trying to persuade the Prince that he should do his duty, and to impress him takes impress him takes on his multi-armed form and says, "Now, I am become Death, the destroyer of wolds." I suppose we all thought that one way or another.
