2. Basic hydraulic innovations www.sturmanindustries.com Leader in hydraulics, magnetic valve/actuators Digital Hydraulic Operating System • Digital Valves—high speed, precise control • Hydraulics—high power density • Intelligent Electronic Control Technology benefits • High switching speed—180 µs @ 0.15-mm stroke • Small size, low mass—3-mm-dia. spool @ 0.5 gram • Low electrical power usage—0.125 W @ 10 Hz • Two stable low- or zero-energy states (no “hold” energy) • Integrated position feedback for fast closed-loop control • Fail-safe designs Hydraulic valves, actuators, pneumatic valves Applications: Mobile hydraulics, pick & place machines (robots), engine controls, pump controls,… Superior motion controls (real-time closed-loop) permit enormous efficiency gains, e.g., starting with a brief “kick” to overcome deadweight inertia, then using only low-energy traverse motion
3. Not just steady technological evolution but “punctuated equilibrium,” even in fundamental and mature applications like fluid flow • Biomimetic rotor from Jay Harman’s firm Pax Scientific, San Rafael, CA (www.paxscientific.com) • Fibonacci spiral shape matches the pattern of minimum-drag laminar vortex flow found throughout nature • In pumps, fans, stirrers, turbines, turboexpanders, etc., such overlooked novel rotor forms can significantly raise efficiency and reduce noise • E.g., computer muffin fans get +30% flow/W or –10 dBa • Commercialization is now starting • Nearly unlimited applications: surprisingly, the phenomena don’t depend on scale or Reynolds number! • May ultimately save >10% of all el.
