A method for producing stable atmospheric pressure glow discharge plasmas using RF excitation and the use of said plasmas for modifying the surface layer of materials. The plasma generated by this process and its surface modification capability depend on the type of gases used and their chemical reactivity. These plasmas can be used for a variety of applications, including etching of organic material from the surface layer of inorganic substrates, as an environmentally benign alternative to industrial cleaning operations which currently employ solvents and degreasers, as a method of stripping paint from surfaces, for the surface modification of composites prior to adhesive bonding operations, for use as a localized etcher of electronic boards and assemblies and in microelectronic fabrication, and for the sterilization of tools used in medical applications.

Thermoelectric devices are provided. In one embodiment, a thermoelectric device may include a glass wafer defined by conductive vias, a second wafer, and a plurality of metal film disposed between the glass wafer and the second wafer and against solid, conductive, integral, end surfaces of the conductive vias. A nanogap may be disposed between the metal film and the second wafer. The nanogap may have been created by applying a voltage extending between the conductive vias and the second wafer. Methods of forming the devices, along with methods of using the devices to transform heat energy to electricity, and for refrigeration, are also provided.

A method and apparatus for a negative index metamaterial lens. The method is used for creating a negative index metamaterial lens for use with a phased array antenna. A design is created for the negative index materials lens that is capable of bending a beam generated by the phased array antenna to around 90 degrees from a vertical orientation to form an initial design. The initial design is modified to include discrete components to form a discrete design. Materials are selected for the discrete components. Negative index metamaterial unit cells are designed for the discrete components to form designed negative index metamaterial unit cells. The designed negative index metamaterial unit cells are fabricated to form fabricated designed negative index metamaterial unit cells. The negative index metamaterial lens is formed from the designed negative index metamaterial unit cells.

A system to detect and identify various aerosol agents, such as biological agents which have been aerosolized, is disclosed. The system generally includes a mechanism to collect a selected sample of atmosphere which may include the aerosol agent, a sub-system to detect the presence and type of agent, and a sub-system to communicate the type of agent detected.
摘要:
A vehicle including a body and three legs. Each leg includes a proximal end coupled to the body, a distal end opposite the proximal end, and an actuator. Each actuator imparts enough acceleration to the vehicle along an axis of the leg to cause the distal end of the leg to leave a surface upon which it rests. Thus, the robot can pivot around one leg when the actuator of another leg imparts an acceleration. One actuator may also cause two legs to leave the surface. Moreover, the actuators may be spring biased into a retracted position. Further, the body may be a Platonic solid and the axes of the lags may pass through the vehicle's center of gravity. Of course, the body could be a sphere while the vehicle could be a planetary robot or a toy. Methods of traversing a surface are also provided.

Methods and apparatus for improved thermal isolation for thermoelectric devices are disclosed. In one embodiment, a thermoelectric device includes a first substrate having a first conductive pad, a second substrate having a second conductive pad, and a gap formed between the first and second conductive pads. At least one of the first and second substrates includes at least one opening positioned adjacent to an outer peripheral edge of the conductive pad. The opening may comprise a trench disposed partially or entirely around the outer peripheral edge of the conductive pad. In operation, the opening inhibits heat transfer between the first and second substrates.
