Audio system for conference rooms

Voler developed a prototype for an audio system with advanced digital signal processing for acoustic echo cancellation, ambient noise cancellation and equalization to maximize performance. The system gets its input through an analog front end that filters, amplifies, and powers microphones.  It can also drive multiple speakers through high quality, high performance DACs.  In addition, the [...]

Wake-Up Circuits

Accelerometers are widely used in electronic products such as phones, gaming controllers and cars. Since they are cheap and ultra-low power, in many products they are part of the wake-up circuit. When they sense movement, they turn on the rest of the systems. However, if they are deployed incorrectly, they will cause intermittent problems with [...]

Biosensors: Avoiding errors measuring physiological functions like EKG, heart rate, and temperature

Wearable medical devices are biosensors attached to the human body to detect and monitor changes and capture biological / physiological data. These devices are usually non-invasive devices that function autonomously. Monitoring older adults and subjects with chronic conditions in the home and community are a growing focus of these applications. Common types of physiological functions [...]

Compressed Sensing – The Latest Advances

Recently MIT announced the latest research in compressed sensing that may soon be saving us money for a wide range of imaging and signal-processing applications. Compressed sensing is a new technique in signal processing and imaging that takes a weighted linear combination of samples. Using simple linear equations, these few samples can represent the complete signal. [...]
