    Abstract: A liquid electrical switch is disclosed that uses a plurality of droplets of conducting liquid to form an electrical path. In a first embodiment, at leas t a first voltage differential is used to create a separation distance between t wo droplets. The droplets are illustratively contained within a housing and surrounded by an immiscible, insulating liquid. In this embodiment, the at least a first voltage differential draws at least a portion of at least one of the droplets away from a second droplet, thus preventing electrical current from flowing from the at least one droplet to the second droplet.In another embodiment, the at least a first voltage differential is changed in a way su ch that at least one liquid droplet is made to come into contact with a second droplet, thus creating an electrical path between the two droplets.

    Abstract: An ordnance fuse apparatus (100) is described that uses electrical and mechanical, and optical devices. The ordnance fuse apparatus includes a controller (150) to control an optical switch (120) and a laser (111) to detonate an explosive charge (140) of the ordnance. Other embodiments include an accelerometer (122) and/or spin detector (123) for detecting that the ordnance has been fired and an optical detector (114) for detecting the proper operation of the laser (111) and a position sensor for detecting correct positioning of the optical switch (120). Another embodiment includes a microlens (130) to focus the laser optical signal onto the ignitor. In yet other embodiments, the explosive charge (140) is detonated either by ignition of an ignitor or by a shock wave from the ignitor. The resulting ordnance fuse apparatus (100) has significantly reduced size and improved performance and safety.

    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.
