    摘要： A method for retrieving data from a data source by querying the data source with data points of a layer. The data points may be encompassed within a determined region of the layer. The steps of the method may include: determining the region of the layer, dynamically querying the data source with one or more data points of the layer encompassed within the region upon determining the region, and receiving the data from the data source.

    摘要： A transponder having a dynamic remapping circuit remaps a value of decision threshold voltage Vdtc and a value of optical power RXP to a reference voltage Vref to minimize the bit error rate BER of a communication system. The dynamic remapping circuit implements a bilinear mapping of Vdtc and RXP to Vref with three bilinear remapping constants “a”, “b”, and “c” selected to align a remapped value of Vdtc_opt to a selected Vdtc normalization value, Vdtc_norm. A transponder in accord with an embodiment of the invention prevents BER from exceeding a threshold value of BER whether RXP or OSNR, or both, remain constant, change continuously, or change intermittently. Constants “a”, “b”, and “c” are related to parameters resulting from mathematically fitting a line to data comprising Vdtc_opt versus RXP. Another embodiment comprises a method for dynamically optimizing Vdtc and RXP to Vref in a transponder with a bilinear remapping circuit.

    摘要： A compound inkjet print head printer has a compound print head module. The compound print head module includes at least two inkjet print heads for providing ink droplets of one color but with different sizes. Since the compound inkjet print head module provides different sizes of ink droplets in a swath, the number of print swaths can be decreased. The compound inkjet print head printer increases a printing speed with high photo quality.

    摘要： A cleaning device is mounted on either of the sides of an ink-jet printer. The cleaning device uses the power source of a paper delivering motor to transmit power to the cleaning units so that the cleaning units rotate to perform cleaning and scrubbing operations for an ink-jet print head. When the printer performs printing operations, the paper delivering motor is used to deliver paper without causing an interference with the ink-jet print head during the printing operation. When the ink-jet print head needs to be cleaned, an ink carriage moves to be opposed to the cleaning device under the ink carriage, then, the paper delivering motor supplies power to drive an external transmission device set. The external transmission device set drives the cleaning device on the revolving seat to rotate so as to clean the ink-jet print head of the ink carriage.
