THE INSTITUTEA German shepherd that lost part of his leg will soon have a new motorized prosthesis, thanks to the Iota Delta chapter of IEEE Eta Kappa Nu (IEEE-HKN) and volunteers at the Stevens Institute of Technology, in Hoboken, N.J.

Buddy was abandoned last year outside of Animal Care Centers of NYC in Brooklyn. Shelter workers believe his left hind leg was ensnared in a wire or wrapped in a rubber band and became infected, causing 1-year-old Buddy to gnaw off his foot and part of his ankle. To save the dog’s life, a veterinary team amputated the bottom part of the leg and attached a prosthesis. The prosthesis gives Buddy a limited range of motion, however. The veterinary team says they expect the limitation would ultimately result in hip dysplasia, which likely would limit the dog’s use of his hind legs.

Deep Learning Could Bring the Concert Experience Home

The century-old quest for truly realistic sound production is finally paying off

Now that recorded sound has become ubiquitous, we hardly think about it. From our smartphones, smart speakers, TVs, radios, disc players, and car sound systems, it’s an enduring and enjoyable presence in our lives. In 2017, a survey by the polling firm Nielsen suggested that some 90 percent of the U.S. population listens to music regularly and that, on average, they do so 32 hours per week.

Behind this free-flowing pleasure are enormous industries applying technology to the long-standing goal of reproducing sound with the greatest possible realism. From Edison’s phonograph and the horn speakers of the 1880s, successive generations of engineers in pursuit of this ideal invented and exploited countless technologies: triode vacuum tubes, dynamic loudspeakers, magnetic phonograph cartridges, solid-state amplifier circuits in scores of different topologies, electrostatic speakers, optical discs, stereo, and surround sound. And over the past five decades, digital technologies, like audio compression and streaming, have transformed the music industry.
