Digital noise cancellation technology via an automatic leakage compensation (ALC) algorithm enables active noise cancellation (ANC) in loose-fit earbud designs, reports ams. The company has developed ALC technology for loose-fit in-ear wireless earbuds to adjust for air leakage between the earbud and the user’s ear in real time. As a result, users can also enjoy augmented hearing and noise cancellation while using loose fitting earbuds.
Wearable
Integrated MEMS inertial module up their game
Designed for augmented reality (AR), virtual reality (VR) and tracking applications, STMicroelectronics has designed the LSM6DSR inertial module for next-generation gaming, industrial, and sports applications.
Bosch adds user interaction and activity tracking to ear accelerometer
User interactions and accurate activity tracking are enabled by the BMA456 accelerometer variant with integrated hearable features. The sensor from Bosch Sensotec will be highlighted at the Sensors Expo and Conference later this month.
Renesas announces memory technology for AI
Renesas Electronics has developed an AI accelerator that performs convolutional neural network (CNN) processing at high speeds and low power. A test chip with this accelerator has achieved the power efficiency of 8.8Tera operations per second per W (TOPS/W), which is the industry’s highest class of power efficiency, reports Renesas. The accelerator is based on the processing-in-memory (PIM) architecture, in which multiply-and-accumulate (MAC) operations are performed in the memory circuit as data is read out from that memory.
