Abstract: A system receives a plurality of data samples associated with a control valve with each of the plurality of data samples associated with a setpoint and a position. A first subset of the data samples that are in a control zone associated with normal operation of the control valve is determined. In a case that a second subset of the data samples are determined to be (i) not in the first subset and (ii) close to a minimum position of the plurality of data samples and (iii) have setpoints less than their associated positions, an alert associated with a low obstruction is indicated. In a case that a second subset of the data samples are determined to be (i) not in the first subset and (ii) close to the maximum position of the plurality of data samples and (iii) have setpoint greater than their associated position, an alert is indicated.

Abstract: An electroluminescent device comprising: an organic electroluminescent element and a junction transistor having a first region, a second region, and an intermediate semiconducting region configured to control flow of charge between the first and second regions, wherein at least two abutting regions consist essentially of one or more semiconducting inorganic metal compounds, and wherein each region of the junction transistor and the electroluminescent element are successively stacked along a common direction.

Abstract: Systems and methods for examining a route inject one or more electrical examination signals into a conductive route from onboard a vehicle system traveling along the route, detect one or more electrical characteristics of the route based on the one or more electrical examination signals, apply a filter to the one or more electrical characteristics, and detect a break in conductivity of the route responsive to the one or more electrical characteristics decreasing by more than a designated drop threshold for a time period within a designated drop time period. Feature vectors may be determined for the electrical characteristics and compared to one or more patterns in order to distinguish between breaks in the conductivity of the route and other causes for changes in the electrical characteristics.

Abstract: A computer-implemented method for monitoring characteristic data includes selecting a first operable system device and receiving a first plurality of data from the first operable system device. The first plurality of data represents at least one characteristic of the first operable system device at a first plurality of points in time. The method also includes determining whether the first plurality of data is useful. If the data is useful, the method also includes receiving a second plurality of data from the first operable system device, the second plurality of data represents at least one characteristic of the first operable system device at a second plurality of points in time, wherein the second plurality of points in time is substantially larger than the first plurality of points in time. If the data is not useful, the method further includes selecting a second operable system device.

Abstract: Some embodiments relate to an absorption probe for measuring an amount of dissolved organic carbon in an aqueous sample, the absorption probe comprising: a housing defining an analysis zone for the containment or passage of an aqueous sample; a light reflector disposed within said housing; an ultraviolet light emitting device disposed within said housing and operable to radiate ultraviolet light along an optical path that passes through the aqueous sample to impinge on said reflector; and a light detector disposed within said housing and operable to detect radiated light reflected from said reflector and to output a received signal from said detected reflected light, said received signal indicative of a measure of an amount of dissolved organic carbon in the aqueous sample.

Abstract: A method allowing a professional service provider to access client data stored in an online account without storing confidential account information by the professional service provider. In particular, the service provider may register the relationship with the client in a third party information transfer framework where the client approves such registration and download the data from the online account using the confidential account information in a temporary manner. The client data may be stored in a repository available to the service provider based on the relationship registration. In an example, a professional tax preparation software may include functionality to check for newly downloaded client data within the third party information transfer framework, notifying a tax accountant (i.e., the service provider), and may provide a one click access to import the client data directly into the client tax return.

Abstract: The invention relates to an aluminium alloy and anode made therefrom containing silicon, iron, copper, manganese, magnesium, chromium, zinc and titanium. The anode is used as a sacrificial anode in water vessels with non-metallic hulls.

Abstract: A process and apparaus for recovery water from raw sewage extracted directly from the sewer including a screen(2) operable to obtain from raw sewage a screened effluent having a maximum particle size of no more than 900 microns. The apparatus also comprises a first membrane separator(5) which is operable to filter the suspended solids from some or all of the screened effluent. The process also includes a second membrane separator preferably in the form of reverse osmosis filter(8).

Abstract: A Fourier transform spectrometer for use, among others, for sensing gases or liquids includes two polarizers, a birefringent optical component interposed between the two polarizers and a detector. Light from an extended source is substantially polarized by a first of the two polarizers, split into divergent beams by the birefringent optical component, and again caused to converge by the birefringent optical component so that, after passing through a second of the two polarizers, the light forms an interferogram in a plane behind the birefringent optical component where the detector is situated. The Fourier transform spectrometer is thereby provided with a way of forming an interferogram of the light from the extended source without a lens or a second birefringent optical component. This improves the field of view of the spectrometer and is likely to reduce its cost.
