    摘要: A method for removing a stationary noise pattern from digital images uses an adaptive noise estimation algorithm to calculate a prediction of the fixed pattern noise and a confidence estimate for the prediction. In one embodiment, a predicted noise value is obtained from the captured image and a predicted image derived from spatial and temporal pixel value prediction techniques. The predicted noise value is used to update a fixed pattern noise estimate only when the confidence estimate for the predicted image is high. In another embodiment, the confidence estimate is used as a weight factor for blending the noise prediction into the noise estimate. In yet another embodiment, the adaptive noise estimation algorithm is applied to a prediction area in the image for calculating scaling parameters which scaling parameters are used to calculate a noise estimate for the entire image based on a reference noise image.

The method comprises the steps of: supplying the electrocardiogram signals in a first processing branch to a low pass filter and a derived value sum generator; comparing the output signal with a threshold value to generate a first comparison result; feeding the electrocardiogram signals in a second processing branch to a derived value generator; comparing said signals with an upper and a lower threshold value to generate a second comparison result; repeat the above steps for the second and if necessary further channels; evaluating all first and second comparison results for all channels in a weighted logic circuit; and triggering the measurement as a function of the result of the weighted logic circuit.

    摘要: A method for providing an identifier for a semiconductor chip after the manufacture of the semiconductor chip using a fabrication process includes selecting one or more circuit elements formed on the semiconductor chip where each of the circuit elements having an electrical parameter that has a time-invariant statistical process variation, measuring data values of the electrical parameter of the one or more circuit elements, processing the data values, and deriving the identifier for the semiconductor chip using the processed data values. The identifier identifies the semiconductor chip from other semiconductor chips manufactured using the fabrication process. The circuit elements can be selected from the group of bipolar transistors, MOS transistors, light detecting pixel elements, and memory cells. The chip identification method is particularly useful for identifying image sensor chips where the dark current values or the defective pixel locations can be used as the chip identifier.

    摘要: A system and methods are shown for handling multiple target memory requests. Memory read requests generated by a peripheral component interconnect (PCI) client are received by a PCI bus controller. The PCI bus controller passes the memory request to a memory controller used to access main memory. The memory controller passes the memory request to a bus interface unit used to access cache memory and a processor. The bus interface unit determines if cache memory can be used to provide the data associated with the PCI client's memory request. While the bus interface unit determines if cache memory may be used, the memory controller continues to process the memory request to main memory. If cache memory can be used, the bus interface unit provides the data to the PCI client and sends a notification to the memory controller. The memory controller identifies the memory request, or returned data associated with the request, and discards it to ensure no data is returned to the bus controller from the memory controller. Once the data is received from the bus interface unit, the bus controller is free to send new memory read requests to the memory controller.

    摘要: A digital imaging system includes an image sensor, a frame buffer and a tone correction circuit. The tone correction circuit computes tone corrected pixel data using one or more tone correction curves. In operation, tone corrected pixel data for a first pixel is computed by generating a pixel mask for an m×n neighborhood of pixels surrounding the first pixel, applying a blending mask of weight factors to the pixel mask and computing a selector value based on the pixel mask and weight factors associated with the blending mask. The selector value is used to derive a first tone correction curve for use to compute the tone corrected pixel data for the first pixel. The first tone correction curve can be selected from the multiple tone correction curves based on the selector value or it can be derived by blending multiple tone correction curves based on the selector value.

    摘要: The invention relates to a superconductive device containing a rotor that can be rotated about an axis of rotation and that comprises a superconductive winding in a winding support. Said winding support has a central cavity, into which two fixed thermal tubes project axially. One of said tubes forms a cooling finger that is closed at the end and contains a second coolant with a higher condensation temperature. The other tube supplies a first cooling with a lower condensation temperature to the central cavity and evacuates said coolant from the cavity. To condense the coolants, the tubes lead to a refrigeration unit, situated outside the rotor and equipped with a refrigeration head and a condenser device.
