Abstract: A sleeping machine includes sleeping machine comprising a housing, a base mounted on a lower portion of the housing, a top cover mounted on an upper portion of the housing, a main control module mounted in the housing, and an electromagnetic module mounted in the housing. The electromagnetic module is electrically connected with the main controller of the main control module. Thus, the electromagnetic module transmits electromagnetic waves with a specified frequency, so as to release and comfort the user, thereby helping the user sleep easily and comfortably.

Abstract: A method and apparatus for identifying and analyzing high power dissipation peaks across a switching device. The method and apparatus include processing voltage waveform data associated with a switching device to determine switching edge and slope parameters for each of a plurality of switching cycles, and identifying those portions of the voltage waveform data associated with switch state transition portions of the plurality of switching cycles. For a plurality of the identified switch state transition portions, respective peak power levels are calculated using portions of the voltage waveform data temporally corresponding to the plurality of identified switch state transitions, and portions of current waveform data associated with the switching device temporally corresponding to the plurality of identified switch state transitions.

Abstract: A method for performing color gamut compression. The method comprises the steps of: (a)receiving pixels indexed to colors of a first palette, (b)receiving a threshold value, (c)assigning one of the colors of the first palette to a second palette and mapping the assigned color thereto, (d)calculating a difference between the colors of the first palette and the second palette, (e)when the differences are larger than the threshold value, assigning the color of the first palette to the second palette and mapping the assigned color thereto, otherwise, mapping the color of the first palette to the nearest color of the second palette, (f)repeating the steps (d) and (e) for all the colors of the first palette, and (g)re-indexing the pixels according to the mapping between the first and second palette.
