Abstract: A method of ensuring program integrity in a benefit system includes accessing sets of data from two or more data sources. Data from at least one of the data sources relates to eligibility of a recipient to receive a benefit under a government program. Electronic data matching is performed using the data sources. The data sources used for the electronic data matching includes one or more government data sources and may include one or more commercial data sources. Results from the electronic data matching using two or more of the data sources are displayed in a consolidated view. Based on the electronic data matching, assessments are made relating to eligibility of the recipient. Based on the eligibility assessments, one or more recommendations are made regarding eligibility of the recipient.

Abstract: A mercury vapour sensor in which the sensor surface is a gold substrate, and gold nanostructures with controlled crystallographic facets are strongly adhered to the substrate. A substantial increase in response magnitude and stability of a quartz crystal microbalance (QCM) based mercury vapour sensor is achieved using this sensor surface. The method of forming gold nanostructures on a gold substrate includes the steps of electrodepositing gold onto a gold working electrode from a solution of hydrogen or alkali metal tetrahaloaureate (III) and an additive such as lead acetate at an electro-deposition temperature between 20 and 40° C. and a deposition time of at least 15 seconds. The growth is controlled by the composition of the deposition solution, the temperature and the current density. The deposition rates may be varied as will the deposition times which are preferably about 150 seconds but may be as long as 15 minutes. The preferred deposition solution contains 2.

Abstract: The invention involves a variable valve timing actuator that allows the opening and closing of engine valves to be variably and individually controlled without using a camshaft. The invention utilizes energy regeneration so energy delivered to a valve while accelerating it is recovered while it is decelerating. Regeneration is preferably provided by potential energy storage devices such as springs. Energy losses are made up by adding energy to the actuator while the valve is stationary (or nearly so) in an open or closed state. This is done by (1) moving the spring seats in relation to the valve, thereby “charging” the springs in relation to the valve, and/or by (2) moving the valve with respect to the spring seats to “charge” the springs with respect to the valve. This energy addition is extremely efficient because it is performed after the potential energy within the springs has already been expended and the valve is sitting stationary in its open and closed positions.
