Abstract:
Methods, systems, and computer-readable media for monitoring a gas are generally described. In some embodiments, the concentration of a gas may be predicted based on gas measurement information received from a gas sensor and gas sensor response information for the gas sensor. The gas sensor response information may include a response curve. In some embodiments, the response curve may include a curve generated based on a Sigmoid function and/or a curve of the first derivative thereof. In some embodiments, the predicted gas measurement value may be generated by predicting an asymptotic value of the gas measurement information based on a rate of change of the concentration of the gas and the response curve.

Abstract:
Apparatus and method for controlling the distribution of product items over a manufacturing line, in particular, for controlling the distribution of potato slices across the width of a fryer in a commercial potato chip manufacturing process, includes a number of sensors for measuring the moisture content of potato chips exiting the frying and a controller for determining whether a moisture content variation state exists that should be corrected. A number of rotatable flume distributors are provided which are controlled by the controller in accordance with position adjustment values in a look-up table corresponding to detected moisture content variations. The flume distributors are then adjusted to modify the distribution of potato slices across the fryer to reduce or eliminate the variation in moisture content of the chips leaving the fryer.
Abstract:
Removal of carbon monoxide, hydrocarbons and nitrogen oxides from the exhaust gas from lean-burn, diesel and other engines which produce exhaust gases containing excess oxygen is provided by a multicomponent catalyst having different catalytic components in sequence, each capable of reducing nitrogen oxides within a particular range of engine operating temperatures. The first catalytic component may be a component such as Au, Pt/Au alloys, oxidized Cu, oxidized Ag, Ga203, In203, SnO2, Cu, Ag or CoO and the first catalytic component reduces nitrogen oxides at a temperature between about 475 and 800 DEG C. The second catalytic component may be a component such as Pt/Ag alloys, Pt or Rh and the second catalytic component reduces nitrogen oxides at a temperature between about 315 and 475 DEG C. The third catalytic component may be a component such as Pt, Pt/Rh alloy, Pt/Pd/Rh alloy or Pt/Rh/Co alloy and the third catalytic component reduces nitrogen oxides at a temperature between about 200 and 425 DEG C.

Abstract:
PH control device (1, 2, 3, 7, 701) comprising a substrate (10, 710), on which is defined a flow path (22, 528, 722) adapted to receive a liquid. The device (1, 2, 3, 7, 701) further comprises a set of electrodes (12, 512), which includes a pH sensing electrode (523, 524) and pH generation electrodes (521, 522). The electrodes are arranged along the flow path (22, 528, 722). The pH sensing electrode (523, 524) is arranged so as to be subjected to a change in pH of a portion of the liquid on the flow path (22, 528, 722), as caused by the pH generation electrodes (521, 522). In addition, the device (1, 2, 3, 7, 701) includes a controller (541, 641), which is configured to apply a voltage across the pH generation electrodes (521, 522), based on a signal obtained via the pH sensing electrode (523, 524) and a reference electrode (526). This enables local control a pH of the liquid portion. The device (1, 2, 3, 7, 701) may further be embodied as a sensor, additionally comprising a detection electrode (525, 625, 625a, 725).
