摘要： A method for supplying power from a battery pack includes monitoring an output voltage of a battery pack, where the battery pack comprises a number of fractions and determining whether the output voltage is below a predetermined threshold. The method further includes adding at least one fraction of the number of fractions to the output voltage, when the output voltage is below the predetermined threshold and removing the at least one fraction, if previously added, when the output voltage is no longer below the predetermined threshold.

摘要： Disclosed is a portable powered device such as a tool, comprising a housing within which is defined a combustion chamber (8) for combustion of a mixture of fuel and a combustion-supporting gas, which mixture is compressed so as to be subjected to a pressure in excess of the ambient atmospheric pressure prior to combustion, combustion of the fuel/combination-supporting gas mixture providing the power by which the device performs its intended task, and wherein the said combustion and/or a further combustive event provides the power to compress a successive fuel/combustion-supporting gas mixture, such that a successive cycle of operation of the device may be performed without requiring manual compression of a fuel/combustion-supporting gas mixture by the user.

摘要： A detector for detecting cargo in a container has a controller block, a transmitter for transmitting light into the field of view, a receiver for receiving reflected light, and a threshold comparator for determining whether the received light meets a threshold for cargo detection. The receiver includes a DC block for removing effects of ambient light. The detector performs detection multiple times and averages the results, which can be compared with a previously stored condition of cargo presence or absence to increase the detection accuracy further.

摘要： A method for mapping a point (pixel) outside a halftone cell to a point inside the halftone cell by determining the size of a rectangle which is tiled exactly by the halftone cell. If the size of the rectangle permits, a threshold array is employed to render the pixel. Otherwise, the pixel is rendered by calculating four potential solutions and selecting one of the four potential solutions based on the where the four potential solutions are located with respect to the halftone cell.
