Title: Innovations of Geoffrey Gaines
Introduction
Geoffrey Gaines is an accomplished inventor based in Berkeley, CA. He holds a total of 4 patents that showcase his expertise in the field of shape memory alloys and actuators. His innovative designs have contributed significantly to advancements in actuator technology.
Latest Patents
Gaines' latest patents include a variety of shape memory alloy actuators. One notable invention is a linear actuator comprised of a plurality of geometric links connected together in a displacement multiplied fashion by a plurality of shape memory alloy (SMA) wires. The links may feature a trigon or chevron configuration, which can be combined with a hexagonal or rhomboidal shaft to create a defined stacking pattern. The shaft extends from the medial portion of the stack, and ohmic heating circuits connect to the non-moving ends of the SMA wires. Various groupings of links in parallel displacement are described in this patent.
Another significant patent involves actuators that employ a shape memory alloy component as the driving element, which includes both linear and rotational devices. An intrinsic return means (IRM) may be imparted to the SMA actuator, thereby reducing the need for a spring return mechanism. The rotational actuator may feature a cylindrical bobbin with a helical groove to receive an SMA wire, allowing for multiple turns in a small length of bobbin to amplify the rotational excursion. Additionally, a plurality of narrow, coaxial rings may be provided, with grooves to receive an SMA wire, enabling each ring to rotate with respect to the adjacent ring upon contraction of the wire.
