Abstract: An electric motor 10 has a stator 14; a wound rotor 20, including a commutator 28; and brush gear for connecting the commutator to a source of electrical power. The brush gear has at least two cage brush assemblies 34. Each cage brush assembly 34 having a brush 40 for making sliding electrical contact with the commutator of the motor; a cage 50 for guiding the brush 40 along a path towards the commutator; and a spring 70 for resiliently urging the brush 40 along the path through the cage 50. The spring 70 is a constant force spring having two coiled end portions which engage the cage 50 at a commutator end portion. The cage 50 has two fingers about which the coiled end portions of the spring 70 locate.

Abstract: An application on a thin client displays a map. A graphical user interface permits the application to receive single gesture inputs of a stylus. If the single gesture input comprises a drag of the stylus a minimum distance, the map is panned such that the map is shifted to a new center view. The displayed map may contain one or more map objects. If the input comprises a single tap on a specific map object, the map object under the tap may be selected and highlighted. Further, a ToolTip for the map object may be displayed. A further tap of the ToolTip may result in the navigation to a link or URL associated with the map object selected. One or more zoom buttons may also be displayed. If a zoom button is tapped by the user, the map may be displayed in a different level of detail.
