  • Patent number: 7253802
    Abstract: An electronic input device has a flexible keyboard for receiving user input and a housing defining a space for accommodating the keyboard. The input device has a compacted state and an extended state. The keyboard adopts a compacted spatial configuration in the compacted state and adopts an extended spatial configuration in the second state. In the compacted state the keyboard is wound on a roll. The input device additionally has a retractable, flexible display having corresponding compacted and extended states so that both the keyboard and the display can be rolled in and out together.

  • Publication number: 20050149799
    Abstract: The present invention relates to integrated circuit with reduced leakage power and in particular to a methodology for retaining an operational state of at least a part of the integrated circuit while the part is in standby/low power mode. In detail, the inventive methodology is based on the use of scan chains being implemented in the integrated circuit for production testing purposes. Via the scan chains circuit-internal state-variable memory element content is read out and/or written in such that the operational state of for instance a specific part (power domain) of the integrated circuit may be captured on the basis of the circuit internal contents, retained in an adequately provided data storage and afterwards scanned into the specific part of the integrated circuit to restore the operational state thereof.
