Patent number: 7649548Abstract: A method transfers image information from a camera module (1) to an electronic device, such as a mobile station (23). In the camera module (1), an image is formed by an image sensor (2) having pixels, where the light to which the pixel (P1,1-Pm,n) is exposed is converted into an analog signal which is converted into digital image information. The image information is transferred in serial form, and the transfer of the image information is controlled by the electronic device (23).Type: GrantFiled: January 19, 1999Date of Patent: January 19, 2010Assignee: Nokia CorporationInventors: Jarno Knuutila, Jari Toivanen, Janne Juhola, Markku Lipponen, Ari Aho, Janne Haavisto, Kaj Saarinen

Patent number: 7644309Abstract: The invention relates to a recovery of a hardware module of an electronic device from a malfunction state. The hardware module is connected via a signal line to a recovery component of the device, a state of the signal line being controlled by the hardware module. The recovery component monitors a state of the signal line. Whenever the signal line is detected not to assume a predetermined state during a predetermined period of time, the recovery component causes a hardware reset of the hardware module.Type: GrantFiled: May 20, 2005Date of Patent: January 5, 2010Assignee: Nokia CorporationInventors: Juha Nurmi, Kaj Saarinen

Patent number: 7516395Abstract: 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.Type: GrantFiled: October 12, 2005Date of Patent: April 7, 2009Assignee: Nokia CorporationInventors: Juha H-P Nurmi, Kaj Saarinen

Publication number: 20070176918Abstract: 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.Type: ApplicationFiled: December 14, 2006Publication date: August 2, 2007Inventors: Ari Aho, Kaj Saarinen
