SiliconIntervention: Low-Level Efficiency Improvements in Class-D

Driven by the need to maximize battery life in portable devices, Class-D efficiency at low output levels is receiving greater attention. This is particularly important to achieve longer battery life in designs such as true wireless earbuds. Power optimized amplification is precisely the goal for Multilevel Class-D, and now there's also Fractal Class-D, a new technology developed by SiliconIntervention, a Canadian company formed in 2019 as the result of the pioneering research and development of its founder Martin Mallinson, the former Chief Scientist at ESS Technology.

MindMics, a health technology startup from Cambridge, MA, announced the issuance of its latest patent, US11844618B2, titled "System and Method for Cardiovascular Monitoring and Reporting." This patent marks a significant leap in the field of cardiovascular health, offering a novel, non-invasive approach to disease monitoring and management using standard true wireless earbuds.

Nanusens has had its first patent granted in the US, with filings in other countries underway, and has more patents in the process of being applied for. These all protect the company's innovative technology of building nanoscale structures within a standard CMOS metal layers to create novel NEMS (Nano Electro Mechanical Systems) sensors. Nanusens recently appointed Dr Graham Hine as Chairman with the goal of driving growth and fund raising for the nanosensors company.
