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 least a first voltage differential is used to create a separation distance between two 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 such 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.

US Classification:

114 67R

Abstract:

A method and apparatus is disclosed wherein nanostructures or microstructures are disposed on a surface of a body (such as a submersible vehicle) that is adapted to move through a fluid, such as water. The nanostructures or microstructures are disposed on the surface in a way such that the contact between the surface and the fluid is reduced and, correspondingly, the friction between the surface and the fluid is reduced. In an illustrative embodiment, the surface is a surface on a submarine or other submersible vehicle (such as a torpedo). Illustratively, electrowetting principles are used to cause the fluid to at least partially penetrate the nanostructures or microstructures on the surface of the body in order to selectively create greater friction in a desired location of the surface. Such penetration may be used, for example, to create drag that alters the direction or speed of travel of the body.

Abstract:

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

US Classification:

429112, 429 62, 429118, 977948

Abstract:

A battery having a nanostructured battery electrode is disclosed wherein it is possible to reverse the contact of the electrolyte with the battery electrode and, thus, to return a battery to a reserve state after it has been used to generate current. In order to achieve this reversibility, the nanostructures on the battery electrode comprise a plurality of closed cells and the pressure within the enclosed cells is varied. In a first embodiment, the pressure is varied by varying the temperature of a fluid within the cells by, for example, applying a voltage to electrodes disposed within said cells. In a second illustrative embodiment, once the battery has been fully discharged, the battery is recharged and then the electrolyte fluid is expelled from the cells in a way such that it is no longer in contact with the battery electrode.

Abstract:

An implantable stent comprises a tubular member having an interior surface and an exterior surface, with a region of at least one of the surfaces being hydrophobic. The region is provided with an array of microstructures or nanostructures that covers first portions of the surface but leaves second portions exposed in the interstices of the array. These structures cause the region to have a dynamically controllable hydrophobicity. In one embodiment, a control device, which is affixed to the tubular member, varies the hydrophobicity of the region. In another embodiment, which is particularly applicable to the delivery of a medicinal substance to fluids in body vessels, the stent also includes such a medicinal substance that adheres to the exposed portions until the control device alters the hydrophobicity of the region and causes the substance to be released into a body fluid in contact with the stent. Various ways to load the stent are described. In yet another embodiment, the tubular member is provided with a mechanism that enables the shape of the stent (e.g., its diameter) in vivo to be controlled dynamically, again by means of external wireless communication. In one more embodiment, sensors are affixed to the tubular member to enable fluid parameters (e.g., pressure, flow rate) to be monitored remotely.
