Abstract:
A method and apparatus for processing metal bearing gases involves generating a toroidal plasma in a plasma chamber. A metal bearing gas is introduced into the plasma chamber to react with the toroidal plasma. The interaction between the toroidal plasma and the metal bearing gas produces at least one of a metallic material, a metal oxide material or a metal nitride material.

Disclosed is a multi-modular maze device comprising a plurality of maze modules interconnected using a plurality of adaptors to configure a plurality of interconnected pathways. The maze modules and the adaptors are removably engaged to each other using hook and loop fastening arrangements. The maze device is capable of being removably installed on a supporting surface (for example, floor), either outdoor or indoor.
Abstract:
Emergency call-routing apparatus, and an associated method, for use in a packet-based, telephonic network. An emergency call router is positioned selectably to provide local call handling functionality to a local network that is normally connected by way of an access gateway to the telephonic network whose operation is normally controlled by a softswitch. The apparatus is used when, e.g., a total communication link failure condition occurs between the access gateway and the softswitch. The emergency call router selectably routes calls within the local network to permit continued, local calling functionality in spite of the failure of the communication link. High-priority calls, such as calls placed to an emergency dispatch center, are routed within the local network to a designated, local-network station. And local calls are also selectably routed by the emergency call router. A call priority scheme is also used in the event that call capacity is exceeded. Calls of higher priority are permitted while calls of lower priority are blocked.
Abstract:
An improved plasma vessel (i.e., plasma applicator) that provides effective cooling includes a plurality of generally linear tubes having a dielectric interior fluidly connected together by dielectric connectors. The tubes and connectors are joined together to form a leak-tight plasma vessel. A cooling system surrounding the improved plasma vessel includes a rigid cooling plate and a deformable thermal transfer material disposed between the plasma vessel and the cooling plate. After use or at an operator's discretion, the plasma vessel can be removed from the cooling system and a new vessel may be inserted in its place. Alternatively, the used vessel may be refurbished and re-inserted into the cooling system. The new or refurbished vessel may or may not be of the same size or configuration as the used vessel. Thermal contact between the cooling system and the new or refurbished vessel, however is maintained through the deformable thermal transfer material.
Abstract:
A method for sequentially detecting multiple target nucleic acid fragments in a sample includes steps of adding a sample into a column having a test snare which has thereon multiple single strand capture DNA sequences; wherein each capture sequence binds specifically with one target nucleic acid fragment, and forms a double strand segment; washing out unbound target nucleic acid fragment; adding a first DNA probe, which has thereon a chemical label, to attach specifically to a probe binding site of the first target nucleic acid fragment; washing out unbound first probe; adding a triggering solution to trigger the chemical label; and detecting signals on the test snare for determining the first target nucleic acid fragment; subsequently, adding a second DNA probe to bind specifically to the second target nucleic acid fragment; washing, triggering and detecting signals for determining the second target nucleic acid fragment in the same manner.
Abstract:
An electrical connector (1) has an insulative housing (10), a plurality of contacts (20) received in the housing, an inner shell (30) surrounding the housing and an outer shell (40) surrounding the inner shell. The connector has a plurality of tabs (251, 263) extending inwardly therefrom. The tabs are constructed in the cover and bottom of the inner shell and can be latched to a mating connector. The out shell is conjoint to and overlaps the inner shell.
Abstract:
A power connector (1) includes an insulating housing (10), a number of contacts (20) received in the insulative housing, a first and a second shielding shells (30,40). The insulating housing has a base (101), and a tongue (103) extending horizontally from the base and including an upper mating face (1031) and a lower mating face (1032) parallel to the upper mating face. A number of receiving passages (105) are defined through the base toward the tongue. A plurality of receiving slots (104) extend from the upper mating face to the lower mating face to communicate with corresponding receiving passages. Each contact has a contact portion (201) received in corresponding receiving slot. The contact portion has a first and a second contact surfaces (202, 203) respectively exposed in the upper and the lower mating face.
Abstract:
A material processing apparatus having an integrated toroidal plasma source is described. The material processing apparatus includes a plasma chamber that comprises a portion of an outer surface of a process chamber. A transformer having a magnetic core surrounds a portion of the plasma chamber. The transformer has a primary winding. A solid state AC switching power supply comprising one or more switching semiconductor devices is coupled to a voltage supply and has an output that is coupled to the primary winding. The solid state AC switching power supply drives an AC current in the primary winding that induces an AC potential inside the chamber that directly forms a toroidal plasma that completes a secondary circuit of the transformer and dissociates the gas.
Abstract:
An optical interleaver is described, comprising a splitting element for splitting an incident beam into a first optical signal directed along a first path and a second optical signal directed along a second path, a first resonant element positioned along the first path, a second resonant element positioned along the second path, and a combining element positioned to receive and to interferometrically combine the outputs of the first and second resonant to produce the output signal. The optical interleaver may be implemented using a free-space configuration using a beamsplitter and a plurality of resonant cavities such as asymmetric Fabry-Perot resonators or Michelson-Gires-Tournois resonators. In an alternative preferred embodiment, the optical interleaver may be implemented in a Mach-Zender-style configuration using couplers and fiber ring resonators.
