Abstract: An electrical connector that includes a first part housing for supporting contacting elements each configured to conductively couple with an electrical power source. First part coupling elements are configured to move between a connected and an unconnected configuration. In the connected configuration, each first part coupling element conductively couples with contacting elements, and in the unconnected configuration the first part coupling elements are not conductively coupled with contacting elements. At least one biasing element is configured to maintain the first part coupling elements in the unconnected configuration. A second part housing supports second part coupling elements each configured to conductively couple with one of the first part coupling elements.

Abstract: A system and method are provided for presenting a list of items to a user via a device having a limited display capability. In general, the number of items in the list may be much greater than the device can display at once. A list module is configured to receive a list of items and determine the number of items, or ranges of items, that may be displayed at once. If the list contains too many items to be displayed on one card, the list module divides them into groups nearly equal in size, so that to display any one item requires the same or nearly the same number of cards. Until each range is less than or equal to the number of items that can be displayed simultaneously, the list module presents (e.g., transmits to the device) cards having successively smaller ranges. Eventually a card will have few enough items to be displayed individually, and the user may make a final selection.
