US Classification:

715229, 715200, 715254, 715271

Abstract:

An item-providing system supplies items to a user device for consumption at the user device via communication infrastructure. The device may correspond to a book reader device or other type of device. In one illustrative case, the item-providing system may provide items to the user device in incremental form or in full form. The item-providing system and user device implement a protocol for determining whether the content should be delivered in incremental form or full form.

Assignee:

Yahoo! Inc. - Sunnyvale CA

International Classification:

G06F 17/30
G06F 3/0484

Abstract:

A system may provide for retrieving data within a selected region of a map is provided. The system may include mobile devices configured to display a map and to receive a user selection of a region of the map. An application server may receive data from the mobile device, representing the user selected region of the map and a search criterion. A database may be in operative communication with the application server and executes a query using the data representing the selected region of the map and the search criterion and to return data results corresponding to a plurality of locations within the selected region and related to the search criterion. The mobile device may further be configured to display the data results corresponding to the plurality of locations on the selected region of the map and the displayed data results are automatically updated when the user moves the selected region of the map.

International Classification:

G01R 31/36
H01M 8/04
H01M 8/24

US Classification:

324434, 429452

Abstract:

A measurement device for measuring voltages along a linear array of voltage sources, such as a fuel cell stack, includes at least one movable voltage probe that measures voltage transitions along an array element. The measured voltage is used to determine a distance of travel of the at least one voltage probe along the fuel cell stack from the speed of the probe and the timing of the transitions.
