20100061139 | RANDOM ACCESS MEMORY CIRCUIT - A random access memory circuit includes a plurality of pixels, each having a light sensitive area and a light blocking layer arranged over at least each of the light sensitive areas. In an alternative embodiment, the circuit includes a plurality of memory elements for storing data. Each memory element may comprise a bit node formed between a photodiode, having a light arranged over the photodiode, and a switching element, where data may be stored. The circuit may also include a plurality of reading and writing circuits for reading and writing data to and from the memory cells. | 03-11-2010 |
20110019048 | SENSOR AND SENSOR SYSTEM FOR A CAMERA - A sensor module has first and second sensor arrays formed on a substrate, with the first and second sensor arrays adapted to share common readout circuitry and shared read out for a pair of sensors on a single array. | 01-27-2011 |
20110057906 | POINTING DEVICES - A touch pad uses a plurality of optical mouse type sensors. The sensors are optimized for detection of motion along the predominant direction of a user's finger as the finger is moved around the touch pad. A first one of the sensors functions to optically sense motion in a first direction, while a second one of the sensors functions to optically sense motion in a second, different, direction. The first and second directions are oriented a closed, for example, circular, path. | 03-10-2011 |

20100245627 | PROCESSING FOR CAPTURED IMAGES - A method is provided for reading a captured image, with the captured image comprising at least first and second parts and a border area positioned between the first and second parts. Converted pixels are obtained by applying digital-to-analog conversion to the pixels in the captured image, and the converted pixels corresponding to the border area of the captured image are stored in a buffer. A first set of processed pixels is obtained by applying image processing to the converted pixels corresponding to the first part of the image and to the converted pixels stored in the buffer, and a second set of processed pixels is obtained by applying image processing to the converted pixels corresponding to the second part of the image and to the converted pixels stored in the buffer. A processed image is provided by combining the first and second sets of processed pixels. Also provided is a processing device for reading a captured image. | 09-30-2010 |

20100244846 | METHOD FOR DETERMINING THE STATE OF HEALTH OF A BATTERY - A method for determining the state of health (SOH) of a battery is provided in which cell impedance is determined continuously, and including determining one or more confidence coefficients that depend on one or several variables selected from cell current, temperature or state of charge or their derivatives or integrals with respect to time, and continuously determining the state of health of the battery at a given point in time, using the state of health of the battery at a preceding point in time corrected as a function of cell impedance determined at the given point in time and weighted by the confidence coefficient or coefficients. The method provides a reliable way of determining the state of health of the battery with greater stability and robustness than existing methods. | 09-30-2010 |
20110307202 | SYSTEM FOR MONITORING THE STATE OF A BATTERY - The invention is a monitoring system for a battery having a plurality of accumulators. The system comprises means for measuring the voltage on the terminals of each accumulator, means for measuring the temperature of the battery, means for measuring the current flowing through the battery, means for calculating a voltage difference between a maximum voltage measured on the terminals of one of the accumulators and a minimum voltage measured on the terminals of one of the accumulators, means for comparing the voltage difference with at least one threshold value depending on the measured temperature and current, and means reporting an error if the voltage difference is greater than or equal to said at least one threshold value. | 12-15-2011 |
