ams Wins Innovation Gold Award at 2017 Sensors Expo for Single Wire Communication Interface that Enables Battery-Free Smart Active Noise-Cancelling Headsets

Austrian company ams, a leading supplier of high performance sensor solutions, has won the prestigious Gold Level Innovation Award at the 2017 Best of Sensors Expo Awards (Sensors Expo & Conference, San Jose, California, 27-29 June 2017). ams won the award for its novel Accessory Communications Interface (ACI), a technology, which enables Active Noise Cancellation (ANC) headsets to operate with no battery in the earphone when connected via a single wire to a host device like a smartphone.

ams announced the launch of a technology which enables noise-cancelling headsets with a four-pole 3.5mm jack to operate for the first time without a dedicated battery power supply. The new Accessory Communication Interface (ACI), invented by ams, uses a single wire to carry power and bidirectional data as well as digital audio signals, enabling small form factor noise cancellation headsets while offering the flexibility to include sensors, LEDs and displays.
