Abstract: A water wheel assembly is disclosed and comprises a water wheel including a plate having a rotation axis and a plurality of circumferentially-spaced receivers, each including a first slit defined through the plate, proximal to the axis, and a second slit defined through the plate, distal to the axis. A vane is provided for each receiver and includes: a body hinged to the plate for movement between a lowered position, flush therewith, and a raised position, angularly extending therefrom; and a pair of flaps extending from the body to: project through respective slits and beyond the plate when the body is lowered; and define, in combination with the body and the plate, a scoop, when the body is raised. The plate is mounted in a flow of water with its axis normal thereto and such that the plate is free to rotate about the axis.

Abstract: The present invention improves the stability of a Web browser by identifying plug-in modules that cause failures. Data in memory at the time of a failure is analyzed and a failure signature is generated. The failure signature is compared to a database of known failure signatures so that the source of the failure may be identified. If a plug-in module to a Web browser is identified as the source of a failure, options are presented to the user who may update the plug-in module with code that does not produce a failure or disable the plug-in module altogether.

Abstract: The present invention provides a method and a computer-readable medium containing computer-executable instructions for allowing a user of an application program to manage add-ons associated with the application program. A user interface that displays the add-ons associated with the application program is provided. The user interface provides the user with the ability to disable or enable the add-ons, the ability to update certain type of add-ons. In addition, an administrator of the application program can approve or deny certain add-ons and disable a user's ability to disable or enable add-ons.
