Abstract: A pulse signal compensation circuit of a pulse generator can include a pulse measurement circuit and a compensation generator circuit. The pulse measurement circuit can be configured to receive a plurality of pulse signals and to generate an average duty cycle or pulse overlap signal proportional to the duty cycle or pulse overlap of the plurality of pulses. The compensation generator circuit can be configured to receive the average duty cycle or pulse overlap signal and generate a duty cycle or pulse overlap compensation signal based on the average duty cycle or pulse overlap signal. The compensation signal can be utilized to adjust the duty cycle, amount of positive or negative pulse width overlap, and or the like of the plurality of pulse signals.

Abstract: An infrared pulse radiation heating method for curing board surface powder comprises melting and curing sequentially performed. The curing is to make a board, with a film formed by quickly melting a power coating, pass through a medium wave infrared pulse radiation area to be heated, the heating is performed alternatively at a high temperature and a low temperature, the medium wave infrared pulse radiation area is formed by separate medium wave infrared pulse radiation heating units consecutively arranged, and medium wave infrared heating tubes in the medium wave infrared pulse radiation area are vertically arranged. Further provided is a device for implementing the heating method. By means of the method and the device, thermal damage is prevented from being incurred to the board, the coated film is uniformly cured, and the energy-conserving effect is improved.

Abstract: In some embodiments, the present invention provides a method for scheduling an indexed data broadcast such that both mean access time and mean tuning time are reduced to a practical minimum. In one embodiment of such a method, data items are first scheduled for broadcast. Such data items are advantageously scheduled such that: (1) all data items to be broadcasted are equally spaced; and (2) when indexed with appropriate “indexing keys,” the indexing information can be efficiently stored and broadcasted. In one embodiment, a schedule having a mean access time about 1.5× that of the theoretical minimum is provided. The indexing information is advantageously arranged in a way that allows for efficient delivery thereof to clients to apprise them of the broadcast schedule of the data items. The indexing information is advantageously arranged in a tree structure referred to herein as an “indexing tree.
