Abstract:
An automated balloonsonde launcher (88) and a method for an automated balloonsonde launch are disclosed. The automated balloonsonde launcher, for example, may comprise a collapsible protective cover (60) forming an inner region for receiving a balloon, a gas inlet for receiving a gas, a gas outlet for mating with a balloon, a valve operable between the gas inlet and the gas outlet for inflating a balloon within the inner region of the protective cover. The launcher further comprises a controller that controls the valve to inflate a balloon within the protective cover, opens an opening in the protective cover and releases a balloon through the opening of the protective cover.
Abstract:
A device and method for measuring the concentrations of components of a fluid stream. In the preferred embodiment, the device comprises a radiation source (12) and a radiation detector (20) for measuring radiation transmitted through the fluid stream. Optics, including appropriate lenses (14a, 16a) and a polychromator (18) disperse the radiation and focus it on the radiation detector. The linear photodiode array (21) is located in the focal plane of the polychromator so that each diode corresponds to particular wavelengths of the spectrum produced by the polychromator. Preferably, the fluid stream is an in situ gas stream, such as a fossil fuel fired flue gas in a smoke stack (24a). The measurements are determined from the intensity of radiation over a selected range of radiation wavelengths using peak-to-trough calculations. The need for a reference intensity is eliminated.
Abstract:
An electrolyte is introduced into an electrochemical device, passed, via a first corrugation feature, through a first electrode of the electrochemical device, passed through an ion permeable separator, and contacted with a second electrode. The first or second electrode comprises a second corrugation feature in fluid communication with the first corrugation feature to contact the electrolyte across a portion of an active surface of the first or second electrode.
Abstract:
The invention relates generally to carbon nano-tube composites and particularly to carbon nano-tube compositions for electrochemical energy storage devices and a method for making the same.
Abstract:
A method and apparatus measures the presence of total residual oxidant species in aqueous environments. More specifically, the apparatus is operable to measure hypohalites (e.g., hypochlorite and hypobromite) in water containing halide salts using electrochemistry. The apparatus can be a sensor having four electrodes - a reference electrode, a working electrode, and two auxiliary electrodes. The fourth electrode, i.e., the second auxiliary electrode, can be used to generate ionized water near and in contact with the working electrode. The ionized water can clean the working electrode to minimize effects due to scaling or biofilm formation. As such, the working electrode does not need the capability to clean itself. Thus, other elements, originally believed to be unsuitable for use in saline aqueous environments, can be used for the electrodes, for example, gold.
Abstract:
An upper extremity prosthetic device is provided that comprises three main components, namely, an arm cuff, a forearm section and a distal connector. The arm cuff is adjustable to accommodate lower arms of different sizes. The forearm section may be constructed in certain limited sizes to accommodate different sized forearm residual limbs. The distal connector is designed to connect to any of the forearm section configurations, and the distal connector enables any terminal device to be attached to the connector. The components may be mixed and matched in various combinations to fit the physical dimensions of virtually any amputee. The interchangeable parts will accommodate a wide range of residual limb geometries, overall sizes and lengths. Embodiments of the present invention minimize the need for time and resource-intensive customized fitting and create an affordable, relatively low-cost prosthetic interface.
Abstract:
The present invention is directed to a pre-positionable prosthetic hand, including one or more pre-positionable joints. Pre-positionable joints in accordance with embodiments of the present invention include a multi-axial thumb joint, a metacarpal- phalangeal joint and a wrist joint. Additionally, the present invention may include a number of pre-positionable phalanges or fingers having a segmented construction, which allows them to be placed in various positions. The present invention may be used in connection with a pentadactyl glove and may be positioned in such griping positions as: a key or lateral grip, a hook grip, a cylindrical grip, a spherical grip and a tip-pinch grip.
Abstract:
The present invention provides systems and methods for quantifying, purifying and separating fullerenes, such as single wall carbon nanotubes (SWNTs). The purification/separation combination provides nearly 100% carbonaceous impurity-free SWNT content from a given impure sample and provides a desired chirality and diameter from a given non-separated sample. Nanometrological validation of the success of purification and separation uses a pyroelectric detector and Raman spectroscopy in a single system, thus providing a critical aspect for the nanomanufacturing environment. The purification/separation and nanometrological validations may be performed in a feedback loop to provide a satisfactorily refined sample and optimized purification/separation settings.

A cable lock device includes a body 204, 616 and a factional shoe 208, 608 operable to engage a Bowden cable 120, wherein, in a first mode, the Bowden cable 120 moves freely in first and second opposing directions 304, 308 and, in a second mode, the shoe inhibits the Bowden cable from moving in the first direction 304 while allowing the Bowden cable to move freely in the second direction 308.
Abstract:
A decontaminating system (200) is provided that includes: (a) a decontaminating apparatus (100) including (i) an electrically conductive scrubbing shoe (104) having an inlet (204) for a gel-like material and (ii) an insulating standoff (116) positioned between the scrubbing shoe (104) and a surface (120) to be decontaminated to maintain a desired distance between the scrubbing shoe (104) and the surface (120); (b) a reservoir (216) for the gel-like material (124), the reservoir (216) being in communication with the inlet (204); and (c) a voltage source (224) in communication with the electrically conductive scrubbing shoe (104), whereby a current is passed through the gel-like material (124) applied to the surface (120), thereby removing contaminants from the surface (120).
