Abstract: A method for open-text searching of information sources owned by a library is provided. The method uses existing full-text search engines and databases of open-text scans of text documents to provide searches which are limited to the actual set of information sources owned by or within a physical library. This set of information sources may be defined by a listing of ISBN or document identification numbers at an access rights database. Users may access this system from computer terminals within the library, or offsite using a unique library patron identification card. Constraints may be placed on the searches which limit the number of users searching a specific book at one time or the level of search access permitted.

Abstract: A device for monitoring wear in a component, including a radio frequency identification chip adapted to be attached with the component and a sensor configured to monitor wear of the component, the sensor being in communication with the radio frequency identification chip. The sensor may be embedded within the component and may include a plurality of circuits of varying lengths to measure different stages of wear.

Abstract: A device for monitoring wear in a component, including a radio frequency identification chip attached with the component and a sensor configured to monitor wear of the component, the sensor being in communication with the radio frequency identification chip. The sensor may be embedded within the component and may include a plurality of circuits of varying lengths to measure different stages of wear. The monitoring device may be employed in a roller, such as the fuser roller in a printing apparatus. The roller may be constructed from a multiplicity of non-conductive layers in which portions of the layers are doped with a conductive material to form the plurality of circuits for sensing wear. The monitoring device may also be employed in a belt for use in a printing apparatus. A printing apparatus may also employ a roller or belt equipped with the monitoring device along with a control system for periodically reading the chip and collecting the wear data.

Abstract: A dynamically reconfigurable input button display provided on an operational face of multi-function physically displaceable buttons allows easy dynamic display of various operating modes or functions associated with operation of the button. The button forms part of a user interface of a input device, such as a piece of office equipment or a hand-held electronics device. The buttons may form an array in which a plurality of discrete functionality displays are provided on each of the buttons. The display is a thin film device, such as an organic LED display.
