CES 2013: Share Battery Power Between Mobile Devices

Fulton Innovation, manufacturer of eCoupled wireless chargers, demonstrated at CES this week what it hopes will be a feature of the next generation of wireless power products—two-way wireless power. The company plans to introduce this technology to the Wireless Power Consortium, the group that developed the wireless power standard Qi, for inclusion in its next update. 

Given that people tend to carry multiple mobile devices, two way charging, the company says, will let people easily share power between devices rather than worrying about making sure they are all fully charged. For example, say a pad computer’s battery is almost out of power, but the user wants to catch the ending of a movie before shutting it off; he might decide to pull a little power from a mobile phone. Alternatively, a laptop or pad computer could act as a backup power source for a smartphone.

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.
