Abstract: A method for determining the volume of a test liquid aliquot used to calibrate a liquid delivery device. The method is useful for determining the volume of an aliquot of a test liquid which is complex, non-aqueous or both. A mixture contains the test liquid and a stock solution including a first dye, the first dye having absorbance characteristics which are measurably distinguishable from the absorbance characteristics of a second dye. The mixture is mixed with a diluent including the second dye to form a sample solution used to measure absorbances of the first dye and the second dye. The test liquid and the stock solution are combined gravimetrically in a controlled ratio so that the flow characteristics of the test-stock mixture correspond to the flow characteristics of the test liquid and without affecting the ability to distinguish the absorbance characteristics between the first dye and the second dye.

Abstract: An all-terrain wheelchair including independently operable right and left push bars arranged to enable individuals of varied physical strength to move the chair along a wide range of terrains, including soft terrain. The push bars allow the user to establish mobility without hand to wheel interaction. The all-terrain wheelchair allows the user to propel the chair forward with a forward motion of the push bars while pulling back on the push bars engages a braking system. Turning is achieved with a forward motion on one push bar and a backward motion on the other push bar. The all-terrain wheelchair of the present invention offers the user a multi-speed geared advantage over traditional wheelchairs. Shifting into lower gears for snow, mud, and sand, gives the user the freedom to go where they have not been able to go with traditional wheelchairs. The push bars are removable and may be stored so that the wheelchair may be moved using conventional hand-to-wheel pushing.

Abstract: A liquid aspirating and dispensing apparatus and method of using the apparatus. Among other elements, the apparatus includes a liquid handling device having one or more channel members, each of which has a removable liquid holding tip attached, and a signal transmitting device. A signal transmitted from the signal transmitting device may be used in a variety of ways to yield information regarding the performance of the apparatus.

Abstract: An energy conserving active thermal insulation arrangement installed upon the ambient surface of an insulated structure employing alternately spaced insulated air channels and insulated conductive ply channels. A thin conductive ply conveys the energy by conduction from the airflow into the adjacent conductive ply channels, that contain an additional layer of foam which improves the conservation of energy. The conductive ply is placed above and below structural openings which would otherwise restrict airflow. The airflow is drawn from beneath the frost line, exhaust ventilation or sunspace. A math model solution determines the energy necessary to maintain a desired room temperature for each hour of the day which characterizes the thermal resistance. As the ambient temperature fluctuates, the resistance varies, however the energy for 24 hours is used to determine the total apparent resistance. Examples of apparent resistance R-value have been improved beyond any published resistance values to date.

Abstract: A flow chamber, imaging objective, condenser and imaging light source as part of an optical system includes an oil-immersion objective and high numerical aperture condenser matched to a rectangular flow chamber. The oil-immersion objective and flow chamber include a high index of refraction immersion oil so as to enhance the optical resolution and optical coupling therethrough. The imaging light source generates light which passes through the condenser, the flow chamber and then the objective before being focused onto an imaging camera. Fluorescence excitation passes through the objective to the flow chamber where the oil immersion configuration enhances the focus and collection of the light back through the objective.

Abstract: A system for demodulation of the Loran Data Channel transmitted over the Enhanced Loran (eLoran) system including a quadrature filter. The quadrature filter calculates the real and quadrature phase components of a received ninth pulse. The resultant components are used to obtain the angle of the ninth pulse. This angle is then compared with a set of pre-tabulated angles/symbols that are calculated using the same quadrature filter on thirty-two different simulated ninth pulses. The closest angle match gives the corresponding symbol. Such twenty-four symbols make up a single Reed Solomon encoded message. This message is then passed through a Reed Solomon decoder and the transmitted message is obtained.

Abstract: A method, apparatus and kit for precisely and accurately determining the volume of a liquid aliquot which can be used to calibrate a liquid delivery device. Two dye-containing solutions, a sample solution and a diluent solution, are prepared such that each solution contains a different dye, with the solutions having different absorbance values at a first wavelength and at a second wavelength. The absorbance value of a known volume of diluent solution is measured at both wavelengths. Either one aliquot of sample solution is added to the diluent solution and then absorbance measurements are made at both wavelengths, or multiple aliquots of sample solution are mixed serially into the diluent solution and then absorbance measurements are made at both wavelengths after each aliquot is added. The volume of any single aliquot is calculated by using a two-step formula which is based on the Beer-Lambert law.

Abstract: A system and method that provides dynamic network policy management. The system enables a network administrator to regulate usage of network services upon initiation of and throughout network sessions. The system employs a method of identifying selectable characteristics of attached functions to establish static and dynamic policies, which policies may be amended before, during and after any session throughout the network based on the monitored detection of any of a number of specified triggering events or activities. Particular policies associated with a particular identified attached function in prior sessions may be cached or saved and employed in subsequent sessions to provide network usage permissions more rapidly in such subsequent sessions. The cached or saved policy information may also be used to identify network usage, control, and security. The system and method of the present invention provides static and dynamic policy allocation for network usage provisioning.

Abstract: A method is disclosed for arranging and exciting the stator, rotor and various windings of a multi-stage brushless high frequency alternator so that the resulting multiple high frequency sub-phase armature winding outputs can be rectified and commutated into three phase power frequency alternating current (AC) electrical output. Power frequency currents in field windings control output amplitude, output frequency, and output phase. Devices incorporating this arrangement are suitable of generating fixed frequency electrical power while accommodating variable speed rotation of a generator shaft and offer multiple advantages over existing techniques. The capability to generate speed independent electric power allows natural power sources such as windmills and hydro-power stations to be efficiently coupled to fixed frequency power grids.
