Abstract: A method and a device are described for selecting between multiple available filters in an encoder to provide a frame having a low error and distortion rate. For each full and sub pixel position, determining whether to use an alternative filter over the default filter during interpolation by estimating the rate distortion gain of using each filter and signaling to the decoder the optimal filter(s) applied to each full and sub-pixel position. In one embodiment, identifying a reference frame and a current frame, interpolating the reference frame using a default filter to create a default interpolated frame, interpolating the reference frame using an alternative filter to create an alternative interpolated frame, determining for each sub-pixel position whether to use the default filter or the alternative filter based on a minimal cost to generate a final reference frame.

Abstract: Denoising such as discrete universal denoising (DUDE) that scans a noisy signal in an attempt to characterize probabilities of finding symbol values in a particular context in a clean signal can perform a rough denoising on the noisy signal and identify contexts from a roughly denoised signal. The rough denoising improves estimation of the statistical properties of the clean signal by reducing the false differentiation of contexts that noise can otherwise create. Statistical information regarding occurrences of symbols in the noisy signal and corresponding contexts in the roughly denoised signal can then be used to denoise the noisy signal. The specifics of the rough denoising can be chosen based on knowledge of the noise or of the clean data. Alternatively, the DUDE can be used in an iterative fashion where the denoised signal produced from a prior iteration provides the contexts for the next iteration.

Abstract: A generator of update packages with a matching component employs a matching technique that allows matching of programs that have been relocated to (compiled for) different memory segments. In relocated programs, the code remains the same, while the pointers assume different values, and the matching component is able to allow for such changes while still being able to match them. The matching component is able to capture in the flagged mismatches the changed pointers, addresses, etc. and thereby preserving long sections of the code that have not been modified.

Abstract: A method, system, and device supporting installation of updates to software and/or firmware in memory of an electronic device. The updates may be accompanied by advertising, promotional and information content that is dynamically displayed to a user during processing of the update in the electronic device. The update information may be automatically generated based upon a list of all software components or packages already present on the electronic device, and may comprise software components for all dependencies of an application being installed by the update that are not already present on the electronic device.

Abstract: A file system based OS, such as CRAMFS, is employed in an electronic device. These OS are embedded in some electronic devices and the file systems have particular behavioral characteristics in these electronic devices embedded OS. Updating files in such file system requires the use of heuristics that help manage the update process. For example, heuristics is used to conduct efficient garbage collection in the device as part of the update process, in a preprocessing step.

Abstract: A discrete, universal denoising method is applied to a noisy signal for which the source alphabet is typically large. The method exploits a priori information regarding expected characteristics of the signal. In particular, using characteristics of a continuous tone image such as continuity and small-scale symmetry allows definition of context classes containing large numbers of image contexts having similar statistical characteristics. Use of the context classes allows extraction of more reliable indications of the characteristic of a clean signal.

Abstract: An undercarriage liner made of plastic for a vehicle is detachably attached to the adjacent vehicle chassis. In order for an undercarriage liner to have a significantly lower weight per unit of area, and thus a definitely reduced total weight, while retaining the same flexural strength and impact strength, the undercarriage liner, in the form of a sandwich structure, has a lightweight core layer of polypropylene foam or unconsolidated glass-mat-reinforced thermoplastic. The core layer is provided with a thin cover layer of polypropylene fiber-reinforced polypropylene on both sides. The two rigid and high-impact cover layers are each thermally bonded to the core layer.

Abstract: An efficient generator for update packages employs one of two possible schemes to perform preprocessing when an ELF file or other similar information is not available. The first technique embeds the preprocessing in the generator loop and does not rely on the knowledge of the architecture. The second technique, called node list technique, needs to know the syntax of the assembly instructions used by the executable.

Abstract: An efficient generator of update packages employs a new command SET PTR CACHE to take advantage of a rudimentary caching mechanism that allows exploiting of local patterns in pointer replacements.

Abstract: A number of methods and systems for efficiently storing defective-memory-location tables. A asymmetrical-distortion-model vector quantization method and a run-length quantization method for compressing a defective-memory-location bit map that identifies defective memory locations within a memory are provided. In addition, because various different compression/decompression methods may be suitable for different types of defect distributions within a memory, a method is provided to select the most appropriate compression/decompression method from among a number of compression/decompression methods as most appropriate for a particular defect probability distribution. Finally, bit-map compression and the figure-of-merit metric for selecting an appropriate compression technique may enable global optimization of error-correcting codes and defective memory-location identification.
