Abstract:
A fluid recirculating cleaning device includes an exhaust port defining an exhaust port longitudinal axis, a fluid source end and an exhaust end defining a first cross-sectional area. A suction port includes a suction port longitudinal axis, a fluid exit end and a fluid entrance end defining a second cross-sectional area greater than the first cross-sectional area. The suction port includes a second outer surface that extends from the entrance end toward the fluid exit end. A vacuum blower motor sucks fluid in through the suction port to create fluid flow away from the vacuum motor and toward the exhaust port exhaust end. The exhaust port exhaust end is recessed from the suction port fluid entrance end and the two ports are located with respect to one another so that fluid flow from the exhaust port will be effectively drawn into the suction port.
Abstract:
Microneedle devices and methods of use thereof are provided for the enhanced transport of molecules, including drugs and biological molecules, across tissue by improving the interaction of microneedles and a deformable, elastic biological barrier, such as human skin. The devices and methods act to (1) limit the elasticity, (2) adapt to the elasticity, (3) utilize alternate ways of creating the holes for the microneedles to penetrate the biological barrier, other than the simply direct pressure of the microneedle substrate to the barrier surface, or (4) any combination of these methods. In preferred embodiments for limiting the elasticity of skin, the microneedle device includes features suitable for stretching, pulling, or pinching the skin to present a more rigid, less deformable, surface in the area to which the microneedles are applied (i.e. penetrate). In a preferred embodiments for adapting the device to the elasticity of skin, the device comprising one or more extensions interposed between the substrate and the base end of at least a portion of the microneedles.
Abstract:
Improved techniques are provided for forming ionized molecules from electrosprayed droplets for analysis by a mass spectrometer. A high voltage is applied to a capillary tube for spraying droplets at substantially atmospheric pressure or above, and the electrosprayed droplets contain sample solute of interest and solvent. The electrosprayed droplets are passed into an ion generating chamber which is maintained at a pressure in the range of from 0.2 Torr to 10 Torr. The walls of the ion generating chamber are controllably heated to a temperature which will desolvate the droplets and produce ionized molecules of interest for analysis by the mass spectrometer. The electrospray technique does not rely upon a countercurrent heated gas flow, and provides a particularly simple and inexpensive means to couple electrospray ionization to either quadrupole or magnetic mass analyzers.
Abstract:
A wheel rim guard includes a body having an outer surface and an inner surface each radiating from a central point and the outer surface and the inner surface each co-terminating and defining a circumferential peripheral edge. The guard also includes a returnably-resilient seal disposed along the circumferential peripheral edge, the seal engaging a wheel rim berm. The guard also includes a handle depending from the outer surface of the body.
Abstract:
A guard comprises a body having an obverse surface and reverse surface, the surfaces in mutually opposed orientation and having a thickness (t) intermediately disposed between the surfaces and with the surfaces mutually terminating at an outer circumferential periphery. The guard includes a first channel disposed within the reverse surface of the body, and a first flexible gasket disposed within the first channel. The guard also includes a handle disposed on the obverse surface of the body. A holder may be included that clips to the handle of the guard to position the guard for hands-free operation.
Abstract:
Described herein is a passive wireless resonating non-linear sensor that is typically based on a ferroelectric varactor. The sensor replies its data at an intermodulation frequency when a reader device illuminates it at two closely-located frequencies. Furthermore, described herein is a general intermodulation read-out principle for passive wireless sensors. A sensor utilizes a mixing element, such as a varactor and it can be equipped with a capacitive, inductive, or resistive sensor element. When the sensor is illuminated with signals with two frequencies it replies the sensor data at an intermodulation frequency.
Abstract:
This publication discloses a method and apparatus for functionalizing nanoparticle systems. The method comprises treating a nanoparticle-containing layer so as to produce a pattern of structurally transformed zones, the treatment comprising applying an electric field through the nanoparticle layer. According to the invention an AC-field capacitively coupled to the nanoparticle-containing layer is used as said electric field. The treatment preferably results in at least partly sintered structures, which can be used as conductors, for example. The document discloses several realizations for utilization of the disclosed functionalization in mass-fabrication lines.
Abstract:
Methods, systems, and products that execute modeled business controls on a modeled input work item to generate a corresponding modeled output work item. Input data values included in the modeled input work item either match or approximate corresponding values included in a corresponding actual input work item. Each modeled business control is defined by business rules that represent a business policy, and the business rules and the input data values of the modeled input work item are used to generate the modeled output work item. An actual output work item from a business process is compared to the modeled output work item. The actual output work item includes actual output data values. The business process changes the actual input work item into the actual output work item. The modeled output work item includes modeled output data values. Differences between the actual and modeled output work items are reported.
