A device is provided for a wound wire that is relatively stiff such as electrical wires, cables or similar. According to a first aspect of the invention, the device comprises a shaft; a hub rotatively mounted around the shaft, the hub comprising a central core and a plurality of arms extending radially outwardly therefrom and at least partially around the wound wire for containing the wound wire and restraining an innermost spire thereof; and guides connected to the shaft for guiding the wire extending from the innermost spire as a free end of the spire is being pulled. According to another aspect of the invention, the device comprises a shaft, a body rotatively mounted on the shaft, a hub mounted around the shaft, and guides connected to the body.

The tunable liquid microlens of claim 3, wherein said plurality of electrodes are disposed within said insulating layer, said plurality of electrodes being insulated from said droplet electrode. 6. The tunable liquid microlens of claim 2, wherein said droplet electrode includes: a conductive transparent substrate disposed along a second surface of said insulating layer, said second surface being opposite said first surface; and a conductive lead coupling said droplet to said conductive transparent substrate. 7. The tunable liquid microlens of claim 1, further comprising a transparent supporting substrate disposed along a second surface of said insulating layer, said second surface being opposite said first surface. 8. The tunable liquid microlens of claim 1, wherein said insulating layer is a substantially planar substrate characterized by a relatively high dielectric strength. 9. The tunable liquid microlens of claim 1, wherein said droplet is substantially encompassed by a liquid that is immiscible with said droplet, said liquid protecting said droplet from evaporation. 10. The tunable liquid microlens of claim 1, wherein said droplet is substantially surrounded by a lubricating liquid that is immiscible with said droplet, said lubricating liquid including said lubricating layer. 11. The tunable liquid microlens of claim 1, wherein said lubricating layer includes a relatively low surface energy liquid. 12. The tunable liquid microlens of claim 1, wherein said lubricating layer includes a silicone oil. 13. A method of tuning a liquid microlens, said liquid microlens including a droplet of a transparent conducting liquid, an insulating layer, and a lubricating layer disposed on a first surface of said insulating layer and between said droplet and said insulating layer, comprising the step of: selectively biasing a plurality of electrodes insulated from said droplet by said insulating layer and said lubricating layer to create a respective voltage potential between said droplet and each of said plurality of electrodes. 14. The method of claim 13, wherein said step of selectively biasing includes the step of selectively biasing said plurality of electrodes to vary an angle between said droplet and a plane parallel to said first surface of said insulating layer. 15. The method of claim 13, wherein said step of selectively biasing includes the step of selectively biasing said plurality of electrodes to reposition said droplet relative to said insulating layer. 16. The method of claim 13, wherein said step of selectively biasing includes the steps of selectively biasing said plurality of electrodes to vary an angle between said droplet and a plane parallel to said first surface of said insulating layer and to reposition said droplet relative to said insulating layer. 17. An apparatus, including: a transmitter, said transmitter providing an optical signal; a receiver, said receiver receiving said optical signal; and a tunable liquid microlens disposed to direct said optical signal from said transmitter to said receiver, said tunable liquid microlens comprising: an insulating layer; a droplet of a transparent conducting liquid; a lubricating layer disposed on a first surface of said insulating layer and between said droplet and said insulating layer; and a plurality of electrodes insulated from said droplet by said insulating layer and said lubricating layer, said plurality of electrodes being disposed such that they may be selectively biased to create a respective voltage potential between said droplet and each of said plurality of electrodes, whereby an angle between said droplet and a plane parallel to said first surface of said insulating layer may be varied and said droplet may be repositioned relative to said insulating layer, whereby a focal length and a lateral position of a focal spot of said microlens are adjusted to direct said optical signal from said transmitter to
