A recuperating four-stroke internal combustion engine obtains improves Carnot efficiency by use of a new and novel cylinder head which captures thermal energy normally thrown away in the exhaust and re-introduces it to the working cycle. This result, long sought by others, has been achieved by incorporating within the head a compact internal recuperative heat exchanger in series with a combustion chamber or pre-chamber. A recuperator-protecting valve segregates the recuperator from hot combustion gases until the gases reach maximum expansion in the cylinder. Recuperators of both common-duct and seperated-duct design are described, the separated duct recuperator permitting higher recuperator temperature and increased efficiency and a reduction in the number of valves necessary to control gas flow. A preferred embodiment employs four valves per cylinder unit, a separated duct recuperator, and an insulating liner that surrounds both the combustion chamber and the recuperator. A similar prototype recuperative engine has demonstrated that recuperation can reduce exhaust temperature as much as 600° Rankine below that attainable in an equivalent Otto Cycle engine.

An active matrix electro-wetting on dielectric (AM-EWOD) device includes a plurality of array elements arranged in an array, each of the array elements including array element circuitry, an element electrode, and a reference electrode. The array element circuitry includes an actuation circuit configured to apply actuation voltages to the electrodes, and an impedance sensor circuit configured to sense impedance at the array element electrode to determine a droplet property at the array element. The impedance sensor circuit is operated by perturbing a potential applied to the reference electrode. The AM-EWOD device includes a common row addressing line. The impedance sensor circuit further is operated by supplying voltage signals over the common addressing line to effect both a reset operation and an operation for selecting a row in the array to be sensed. The circuitry isolates the array element from the actuation voltage during operating the impedance sensor circuit.

An improved method of controlling air pollution, a combustion gas is passed through a solution of an alkaline-earth metal sulfide and a redox buffer (e.g., a mono alkaline-earth metal phosphate salt), preferably but not essentially in combination with an alkaline-earth metal carbonate FGD system. The reagents are provided in a fully soluble form enabling low cost application and retrofitting of existing facilities whilst also including alkaline-earth bases salts, which advantageously afford stability to the process product. The reagents co-precipitate when the solution achieves a pH of 4.5 to 6.5 such as is encountered in the acidic environment in conduits that carry combustion flue gases.
