Abstract:
Cabinets (10) are formed by a frame (60) enclosing shelves. The frame (60) has a plurality of openings in the front face (70, 71) of the cabinetry to allow access to the contents of the cabinets (10). The openings are covered by doors (21, 22, 31, 32, 41, 42, 51, 52) connected to the frame by hinges. Art work covers the doors (21, 22, 31, 32, 41, 42, 51, 52) and frames (60) of the cabinets (10) and is arranged so that the art work is not distorted or interrupted by the division of the cabinetry front between the doors (21, 22, 31, 32, 41, 42, 51, 52) and frame (60). The artwork extends across the door (21, 22, 31, 32, 41, 42, 51, 52) onto the frame (60) in such a manner as to give the impression that it is a single piece of art. When viewed from a distance, the viewer sees the complete work of art even though the doors (21, 22, 31, 32, 41, 42, 51, 52) are operable.
Abstract:
Portable microwave plasma systems including supply lines for providing microwaves and gas flow are disclosed. The supply line includes at least one gas line or conduit and a microwave coaxial cable. A portable microwave plasma system includes a microwave source, a waveguide-to-coax adapter and a waveguide that interconnects the microwave source with the waveguide-to-coax adapter, a portable discharge unit and the supply line. The portable discharge unit includes a gas flow tube coupled to the supply line to receive gas flow and a rod-shaped conductor that is axially disposed in the gas flow tube and has an end configured to receive microwaves from the microwave coaxial cable and a tapered tip positioned adjacent the outlet portion of the gas flow tube. The tapered tip is configured to focus microwave traveling through the rod-shaped conductor and generate plasma from the gas flow.
Abstract:
Method, systems and computer readable media for optimizing data acquisition of microwave plasma are disclosed. The present invention provides a method that includes the steps of selecting an operational condition for a plasma generation system, operating the plasma generation system under the selected operational condition, determining whether a stable plasma is established using a sensing device and acquiring/storing plasma data if the stable plasma is established. The method further includes a step of repeating data acquisition under various operational conditions to establish a database for plasma characterization. The present invention further provides a feedback control module that operates in conjunction with a plasma generating system to automate and optimize the process of data acquisition.
Abstract:
Systems and methods for generating relatively cool microwave plasma are disclosed. The present invention provides a microwave plasma nozzle that includes a gas flow tube through which a gas flows, and a rod-shaped conductor that is disposed in the gas flow tube and has a tapered tip near the outlet of the gas flow tube. A portion of the rod-shaped conductor extends into a microwave cavity to receive microwaves passing in the cavity. These received microwaves are focused at the tapered tip to heat the gas into plasma. The microwave plasma nozzle also includes a vortex guide between the rod-shaped conductor and the gas flow tube imparting a helical shaped flow direction around the rod-shaped conductor to the gas flowing through the tube. The microwave plasma nozzle further includes a mechanism for electronically exciting the gas and a shielding mechanism for reducing a microwave power loss through the gas flow tube.

Abstract:
The present invention provides microwave plasma nozzle array systems (10, 70, 230, and 310) and methods for configuring microwave plasma nozzle arrays (37, 99, and 337). The microwaves are transmitted to a microwave cavity (323) in a specific manner and form an interference pattern (66) that includes high-energy regions (69) within the microwave cavity (32). The high-energy regions (69) are controlled by the phases and the wavelengths of the microwaves. A plurality of nozzle elements (36) is provided in the array (37). Each of the nozzle elements (36) has a portion (116) partially disposed in the microwave cavity (32) and receives a gas for passing therethrough. The nozzle elements (36) receive microwave energy from one of the high-energy regions (69). Each of the nozzle elements (36) includes a rod-shaped conductor (114) having a tip (117) that focuses on the microwaves and a plasma (38) is then generated using the received gas.
Abstract:
An advertising and promotional display device has a display sheet formed into a closed loop which is wound around a pair of rollers. A motor is connected to an upper one of said pair of rollers to rotate the roller and revolve the sheet around the pair of rollers in order to show a continuously moving set of images imprinted on the sheet. A pair of stands supports the motor as well as the upper roller so that the pair of rollers and the sheet are essentially suspended from the top ends of the stands. The rollers are composed of detachably interconnected roller members and the stands are also composed of detachably interconnected stand members enabling the device to be collapsed down into component parts for portability. A shroud covers the upper roller, the top ends of the stands and part-of the sheet. The shroud is composed of detachably interconnected segments enabling it to be collapsed into component parts for portability.

A mirror device for a vehicle comprising a base detachably attached to an internal portion of the vehicle, within a viewable range from a driver sitting behind a steering wheel of the vehicle, a mirror attached to a mirror pad, and a substantially elongate member connecting the mirror pad to the base. The elongate member is formed of belt rings and miniature dumbbells alternately interlinked with the belt rings such that each ball of the dumbbells is rotatably caught in a corresponding one of the belt rings, whereby the elongate member is controllably adjustable to one of an infinite number of aerial settings thereof so that the mirror is subsequently displaced to an aerial position desired by the driver.
