Abstract: An example apparatus comprising a heat dissipation mechanism and a controller to detect a temperature of a surface of the apparatus, in response to detecting that an audio output device is connected to the apparatus, determine a thermal profile, and instruct the heat dissipation mechanism to dissipate heat from the apparatus based on the thermal profile.

Abstract: In some examples, a method for compressing a spectral reflectance dataset may be performed through compression circuitry. The method may include computing a principal component analysis basis for the spectral reflectance dataset; projecting the spectral reflectance dataset onto the principal component analysis basis to obtain a weight matrix; quantizing the weight matrix; performing a Huffman encoding process on the quantized weight matrix to generate a Huffman table and Huffman codes for the quantized weight matrix; and providing compressed spectral reflectance data as the principal component analysis basis, the Huffman table, and the Huffman codes.

Abstract: At least one value of abnormal metrics is identified as being an abnormal dimension value. A dominant dimension related to the anomaly is identified based on the identified abnormal dimension value.

Abstract: A method for generating a clustered halftone representation of a continuous-tone image for printing includes applying a search technique. In the search technique, evaluation of a similarity between an initial halftone and the continuous-tone image includes application of an initialization filter to an initial error image that represents a difference between the initial halftone and the continuous-tone image. Evaluation of a similarity between each updated halftone, formed by modifying a previously-evaluated halftone, and the continuous-tone image includes application of an update filter that is different from the initialization filter to an updated error image that represents a difference between the updated halftone and the continuous-tone image. Relating computer program product and data processing system are also disclosed.

Abstract: According to an embodiment of the present invention, there is provided a system for cooling. The system comprises an equipment rack installable in a facility and for accommodating a plurality of electronic equipment. The system further comprises an exhaust duct into which the electronic equipment, when installed in the rack, exhausts gas drawn from a first section of a facility. The system further comprises a gas flow meter for measuring gas flow in the exhaust duct, and a controller for generating control signals to control, based on the measured gas flow, the output of a cooling unit arranged to provide cooled gas to the first section of the facility.

Abstract: A method for determining locations in a predefined area for placing a Radio Frequency Identification (RFID) reader in order to obtain a full coverage of the predefined area is provided. The method includes arranging a plurality of hexagonal area to form a combined area until the total area of the combined area is equal or larger than the predefined area, aligning the predefined area within the combined area, and determining the hexagonal area which is fully or partially covered by the predefined area. Each hexagonal area represents an area of coverage of the RFID reader, and the center of the hexagonal area which is determined to be fully or partially covered by the predefined area corresponds to one of the locations for placing the RFID reader.
