    Abstract: PROBLEM TO BE SOLVED: To provide a tunable liquid microlens which increases the latitude for the selection of materials, which shows excellent tuning performance, and which decreases or eliminates the contact angle hysteresis and the stick slip effect. SOLUTION: The tunable liquid microlens includes an insulating layer 24, a transparent conductive liquid droplet 22 and a lubricating layer disposed on a first surface of the insulating layer and between the droplet and the insulating layer. The microlens contains a plurality of electrodes 26 insulated from the droplet by the insulating layer and the lubricating layer. The plurality of the electrodes are arranged in such a manner that a bias voltage is selectively applied between the droplet and each of the plurality of electrodes to generate the respective voltage, and thereby, the angle θ between the droplet and the plane parallel to the first surface of the insulating layer can be varied and the position of the droplet can be varied with respect to the insulating layer.

    Abstract: A tunable liquid microlens (100) includes an insulating layer (104), a droplet of a transparent conducting liquid (102) disposed on a first surface of the insulating layer and a plurality of electrodes (106) insulated from the droplet by the insulating layer (104). The plurality of electrodes are disposed such that they may be selectively biased to create a respective voltage potential between the droplet and each of the plurality of electrodes, whereby a contact angle (&thetas;) between the droplet and the first surface is variable and the droplet may be repositioned along the first surface.

    Abstract: An optical fiber assembly (101) includes an optical fiber (102) having at least a portion thereof surrounded by a ferrule (111), and a microlens (107). Said optical fiber (102) and ferrule (111) have a common face (109). Said microlens (107) is joined to the face (109) of the optical fiber (102) and ferrule (111), the microlens (107) being made from a pre-dispensed droplet (115) of a liquid (21) which adheres to the face (109) such that a focal point of said microlens (107) is located at a selected point on, or at a selected distance from, said face (109).

    Abstract: A method and apparatus are disclosed wherein a battery comprises an electrode having at least one nanostructured surface. The nanostructured surface is disposed in a way such that an electrolyte fluid of the battery is prevented from contacting the electrode, thus preventing discharge of the battery when the battery is not in use. When a voltage is passed over the nanostructured surface, the electrolyte fluid is caused to penetrate the nanostructured surface and to contact the electrode, thus activating the battery. In one illustrative embodiment, the battery is an integrated part of an electronics package. In another embodiment, the battery is manufactured as a separate device and is then brought into contact with the electronics package. In yet another embodiment, the electronics package and an attached battery are disposed in a projectile that is used as a military targeting device.
