20090212760 | Supply current based testing of CMOS output stages - A CMOS driver test configuration, which allows both leakage current and load current testing, using a single monitor, or current meter, located in a power lead of a tester connected to a power pad servicing the driver circuits. Both leakage testing and load current testing for CMOS drivers is described. The test configuration allows a plurality of driver circuits connected in parallel between power pads to be tested simultaneously. An ESD device, internal to the chip, is used as a load during load current testing in chip testing, and an external load is used during package testing in order to include the bonding means between the chip output pad of the driver and the package I/O pin in the current path during load current testing. | 08-27-2009 |

20100295760 | Advanced multi line addressing - A circuit for a flat panel display, capable of displaying images, is provided. The circuit includes an image storage and processing block for the images to be displayed, a display and timing controller block controlling the display operation, an image pixel matrix containing a multitude of rows and columns arranged pixel elements. The circuit also includes one or more controlled row driver blocks, one or more controlled column driver blocks, and a pixel display operation for displaying pixel elements employing an advanced multi line addressing operation applied to a row and/or column drive activated pixel element display operation. The advanced multi line addressing operation signifies that during every operating sequence a decomposition operation of image data is taking place by analyzing image data from multiple lines for common contents by pixel data comparison, separating common parts of the image data into a multi line data domain and residual parts of the image data into a single line data domain thus allowing for a display of these two data domains in separately activated pixel element display operations. | 11-25-2010 |

That TMLA operation comprises a decomposition of image data by searching all lines of an image for groups of identical lines by tagging each of these lines with a unique code and thus decomposes image data into multi line and single line domain data in such a way, that lines with matching tags, indicating their common and identical contents, are outputted as image data into related groups of the multi line domain with no left over residual image data and thus the related groups in the single line domain data are all zeroes. | 11-25-2010 |
20100295861 | Extended multi line address driving - A circuit for a flat panel display includes an image storage block, a display and timing controller block, an image pixel matrix containing a multitude of row and column arranged pixel elements, also one or more controlled row and column driver blocks, and a pixel display operation employing the extended multi line addressing (XMLA) operation. That XMLA operation comprises a decomposition of image data by analyzing image data from at least two lines from the image data but employing as many lines of the image data as possible according to a certain ‘best match’ criterion directly expanding these operations over their ‘widest possible range’ of lines using that ‘best match’ criterion to find within multiple lines common parts of contents, then separating these common parts into a multi line and the residual parts into a single line data domain thus allowing for a separate display of those data domains. | 11-25-2010 |
20110227815 | PWM precharge of organic light emitting diodes - Methods for PWM precharging of organic light emitting diodes (OLEDs) have been disclosed. Image quality has been improved by including the light generated during pre-charge phase is included in the overall budget. The approach invented is especially beneficial to displays using Multi-Line Algorithms (MLA). Constant discharge time for anodes, discharging the anodes to just below the luminance level saves power by reducing the pre-charge requirements for the next driving phase. High impedance terminal (HiZ) discharge is performed after a fixed discharge of anodes. | 09-22-2011 |

20130231118 | FEMTOCELL ACCESS CONTROL - Methods and apparatus for controlling access of a mobile device to a femtocell base station in a communications network are described. The method determines whether to allow access of the mobile device to the femtocell base station based on the femtocell-mobile device path loss for transmissions between the mobile device and the femtocell base station. Access may be allowed if the femtocell-mobile device pathloss is lower than a threshold amount. Additionally or alternatively access may be allowed only if the femtocell-mobile device pathloss is lower than the macrocell-mobile device pathloss for transmissions between the mobile device and a macrocell base station. The method is particularly applicable for hybrid access mode femtocells and additional conditions may be applied regarding the number of mobile device that are not part of the subscriber group that can access the femtocell. The method may be implemented by the femtocell, the macrocell or by any other suitable network device. | 09-05-2013 |

20080251071 | Method and system for motor failure detection - Systems and methods for detecting developing faults in a flow generator or ventilator during therapeutic use thereof are provided. The motor current may be measured to estimate the torque input by the motor, while the output torque from the impeller may be determined (e.g., as inferred from the motor control system model and/or by consulting a lookup table).
