  • Patent number: 9709713
    Abstract: High quality flexible optical mirrors (in a single or multi-layer implementation) are fabricated from polymer matrix composite material(s) by replication, cast-spinning, and 3-D printing processes. These mirrors are suited as controllable mirrors for different applications including telescope mirrors. The mirrors made from “smart” materials (carbon nanotubes in epoxy) attain controlled properties that may be changed by application of external stimuli, including stress, temperature, moisture, electric and magnetic fields, as well as electromagnetic fields. When formed with non-ferrous metal particles embedded in epoxy, the mirrors are suited for cryogenic operations. The mirrors formed with the ferromagnetic/epoxy material can be deformed and steered by magnetic or electromagnetic fields.

  • Patent number: 8521305
    Abstract: A lead includes an elongated body and an anchor segment disposed between the distal end of the body and electrodes on a distal portion of the body. The anchor segment has lobes which are separated by slits and movable between a collapsed position and an expanded position. A positioning mechanism is disposed inside the hollow interior of the body and at least partially within the anchor segment. The positioning mechanism has a distal positioning portion attached to the distal end of the body and a proximal positioning portion. A control member is connected with the proximal positioning portion to control the positioning mechanism to pull the distal end toward the proximal end so as to move the lobes from the collapsed position to the expanded position and to push the distal end away from the proximal end so as to move the lobes from the expanded to the collapsed position.
