Latest Patents

Among his most notable inventions is the **Miniature Thermoacoustic Cooler**. This MEMS-based thermoacoustic cryo-cooler is designed for the thermal management of cryogenic electronic devices. It effectively integrates a cooling system directly into cryogenic devices. Utilizing a vertical comb-drive, this invention generates an acoustic source through a driving plate that excites a standing wave within a resonant tube. This process creates a temperature differential across a stack within the tube, enabling efficient heat exchange. Notably, the invention features a tapered resonant tube that enhances cooling efficiency compared to conventional cylindrical designs, resulting in reduced harmonics and potent standing waves.

Additionally, Hammer holds a patent for a **Vertical Comb Drive Actuated Deformable Mirror Device and Method**. This innovative deformable mirror design includes a vertical comb actuator with a reflective surface attached. The comb drive's structure comprises stationary elements interspersed with moving components. When a potential difference is applied, the moving parts are pulled downward, deforming the reflective surface. This technology typically utilizes multiple actuators that can be individually addressed, ensuring precise control. Springs play a critical role in maintaining the reflective surface's original position, while the vertical comb drive allows for a large stroke and a linear voltage-to-displacement response throughout its range.
