Abstract: In one embodiment, a distance that a target moves is calculated utilizing an optical sensor. A first temperature of a first portion of the optical sensor is measured at the time of the distance calculation. A second temperature of a second portion of the optical sensor is measured at the time of the distance calculation. The distance is adjusted by a compensation factor that is a function of the first and second temperatures.

Abstract: A bidirectional signal separation module includes a comparator having a first input node communicatively coupled to a bidirectional single-ended bus, a second input node communicatively coupled to a first voltage source, and an output node communicatively coupled to a unidirectional data transmission node; and a resistive network having a first node communicatively coupled to the second voltage source, a second node communicatively coupled to the bidirectional single-ended bus, a third node communicatively coupled to ground, and a fourth node communicatively coupled to an electronic switch. The electronic switch is configured to alternately couple the fourth node of the resistive network to the second voltage source or ground according to a voltage level on a unidirectional data receiving node.

Abstract: A reaction chamber with a fluidized bed encloses two superposed cyclone separators connected in series. In order to prevent combustion gases from entering the lowermost separator by way of its particulate matter outlet, this is formed as a downwardly extended pipe, which is enclosed by a sleeve through which secondary air passes. The sleeve projects somewhat below the mouth of the pipe, and the issuing air causes an ejector action, which prevents gas from entering the pipe. The particulate matter return flow pipe from the upper cyclone is also extended downwards and terminates within the ejector. A storage vessel is located below the reaction chamber. An open conduit extends from the storage vessel to a location above the fluidized bed. Also, there is a return conduit for returning material from the storage vessel to an area above the fluidized bed. An equalizing conduit connects the vessel with an ejector supplying air to the fluidized bed.
