Ultrasound Could Replace Proximity Sensors In Phones
Elliptic Labs recently launched new software that could negate the need to install proximity sensors in smartphones. The company proposes using ultrasound waves, generated by the phone's earpiece speaker and microphone, as a way to eliminate sensors. The ultrasound waves would be processed by Elliptic Labs' Beauty ultrasonic software, which is able to determine proximity based on changes in the waves when phone users' hands or face are near to the phone. Elliptic says Beauty is able to measure proximity at greater distances than physical sensors, and isn't confused by skin color or external temperatures, which can also impact physical sensors' reliability. The company further claims its technology can reduce the cost of smartphone hardware and manufacturing, free up internal space for other components, and allow for more cosmetically appealing designs. Elliptic Labs says it is working with phone makers to integrate Beauty into future handsets.

Elliptic Labs hopes to let people interact with their phones via hand gestures. The company is using the speaker and microphone already installed on most smartphones to emit sound waves, which its algorithms can then decipher as you move your hand closer to the phone.

OmniVision Partners with Almalence for Low-Light Performance
OmniVision Technologies today announced that it is working with Almalence to improve the low-light capabilities of its products. Specifically, OmniVision is pairing Almalence's computational imaging algorithms with its own OV10823 and PureCel OV13850 image sensors.
This is neat.
As far as I'm aware, normal smartphone mics and speakers have limited frequency output and input (based on my own tests as an audiophile and musician), so... How does this work?
