    • Image or other data is stored in a memory. A first validation parameter (e.g., a checksum) is determined for the data stored in the memory at a first time, and stored. A second validation parameter is determined for the data stored in the memory at a second time, and also stored. The stored first and second validation parameters are then compared. In this manner, corruption of data in the memory may be determined by the comparison. In the case where the compared first and second validation parameters are not identical (within a threshold in certain embodiments), the data stored in the memory is updated. As applied to graphical image data, this is seen as advantageous over the prior art approach of periodically updating a frame memory even when no new image data set is present. Apparatus and computer program products are also detailed.
    • 图像或其他数据存储在存储器中。 对于第一次存储在存储器中的数据确定第一验证参数(例如,校验和)并存储。 为第二次存储在存储器中的数据确定第二验证参数,并且还被存储。 然后比较存储的第一和第二验证参数。 以这种方式,可以通过比较来确定存储器中的数据的损坏。 在比较的第一和第二验证参数不相同的情况下(在某些实施例中在阈值内),更新存储在存储器中的数据。 应用于图形图像数据,即使在没有新的图像数据集存在的情况下,这被认为优于周期性地更新帧存储器的现有技术方法。 仪器和计算机程序产品也是详细的。

    • An energy-conserving mobile station and a means for reducing the energy consumption of a mobile station and to reduce burn-in on the display element, where a part of the liquid crystal display element (LCD) of a mobile station is switched off, when the whole display element is not needed and a limited amount of information is displayed on the switched-on part of the display element (A1). An arrangement according to the present invention can be implemented by e.g. driving the control circuit (DC) of the liquid crystal display that supports the partition of the display element to switch of certain rows of the display element in energy conservation mode and switching them on to be used, when information is desired to be displayed on all of the display element.
