If an OEM chooses to implement multiple ambient light sensors (to address issues like a hands or shadows obscuring the ALS), the OEM should expose one logical (consolidated) ALS to Windows and report the most accurate data.If multiple sensors are exposed to the system, the single sensor used...
An adaptive, feed-forward, ambient noise-reduction system includes a reference microphone for generating first electrical signals representing incoming ambient noise, and a connection path including a circuit for inverting these signals and applying them to a loudspeaker directed into the ear of a user...
The auto-brightness service in Windows needs to be able to detect a reasonable range of light levels from 1 to 10,000 lux. If the range is smaller than this, the adjusted auto-brightness may not be able to match the actual brightness of the environment....
The invention provides improved ambient noise reduction for ear-worn devices, such as earphones and headphones and for other devices worn upon or used in close proximity to the ear, such as cellular telephone handsets, and it provides, in particular, improvements to "feed-forward" ambient noise-...
A signal processing circuit is intended for use in a noise reduction system, which produces a target filter characteristic that would achieve optimal noise cancellation, the target filter characteristic including a resonant peak at a fir... A Sibbald - US 被引量: 10发表: 2007年 Headset with a...

Third octave bands were implemented using 6-pole Butterworth band pass filters in concurrent non-overlapping 10 s windows before computing the TOLs as the root mean square (RMS) levels after those filters. The TOLs subsequently served for computation of weekly and monthly levels. Further, the ...
