Abstract: A technology is described for orienting a user interface. An example of the technology can include receiving touchpoint data for a plurality of touchpoints detected by a touchscreen sensor. The touchpoint data can be analyzed to determine distances between each touchpoint to other touchpoints in the plurality of touchpoints, and the touchpoints can be ranked based on the distances between the touchpoints. A vector can be calculated for a top ranked touchpoint, where the vector can have a direction that extends from a center point of a circle fitted to the touchpoints to the top ranked touchpoint. An orientation of a user with respect to the touchscreen can be determined based on the direction of the vector, and the user interface can be displayed on the touchscreen to correspond to the orientation of the user to the touchscreen.

Abstract: An architecture for providing a legacy software application with touch gesture recognition includes an overlay software application and a converter plug-in software application. The overlay application is configured to intercept and detect touch gestures and provide gesture information to the converter plug-in application. The converter plug-in application converts the detected gesture information into data that the legacy application can use. The converted data is provided to the legacy application via an API. The touch gesture recognition is essentially unnoticeable by the user as the overlay application is positioned over the legacy application and is effectively transparent.

Abstract: A process for recovering precious or base metals from particulate refractory sulfide materials comprises: a) contacting the sulfide material with an aqueous solution containing a thermotolerant bacteria culture capable of promoting oxidation of the sulfide material at a temperature in the range from 25.degree. to 55.degree. C., b) separating the oxidized residue from the aqueous liquid, and, c) treating the oxidized residue and/or the aqueous liquid to recover metal. In this context, a thermotolerant bacterium is one which has an optimum growth temperature of 40.degree. to 45.degree. C., and an operating temperature of 25.degree. to 55.degree. C.

Abstract: A seal for maintaining closure between a hollow cylindrical member and an end member closing the cylindrical member, the seal accommodating radial movement of the cylindrical member and movement of the end member in the direction at right angles to such radial movement.
