摘要： An electric arc welding system for creating an AC welding arc between an electrode and a workpiece wherein the system comprises a first controller for a first power supply to cause the first power supply to create an AC current between the electrode and workpiece by generating a switch signal or command with polarity reversing switching points in the first controller, with the first controller operated at first welding parameters in response to first power supply specific parameter signals to the first controller. The system has at least one slave controller for operating a slave power supply to create an AC current between the electrode and workpiece by reversing polarity of the AC current at switching points where the slave controller is operated at second welding parameters in response to second power supply specific parameter signals to the slave controller. An information network connected to the first controller and the slave controller and containing digital first and second power supply specific parameter signals for the first controller and the slave controller and a digital interface connects the first controller with the slave controller to control the switching points of said second power supply by the switch signal or command from the first controller.

摘要： Electric arc welder (10) performs a given weld process with selected current waveform performed between electrode (24) and workpiece (26). Welder (10) includes a controller with a digital processor (30), sensor (44) for reading instantaneous weld current, and circuit (56) to convert the instantaneous current into a digital representation of the level of instantaneous weld current. Digital processor (30) has program circuit (64, 66) to periodically read and square the digital representation at a given rate, register (70, 72) for summing a number N of square digital representations to give a summed value, and an algorithm (82, 84, 86, 88) for periodically dividing the summed value by the number N to provide a quotient and then taking the square root of said quotient to thereby digitally construct rms signal (40) representing the root mean square of the weld current.

摘要： In a tracking radar system target glint and multipath sometimes produce signals which falsely indicate high acceleration rates of the target. These signals cause the boresight of the antenna to be driven away from the direction in which the target actually lies.To avoid this problem, received signals from a receiver are fed through a switch which is opened whenever the target appears to have an acceleration or velocity above a threshold value. The threshold value is varied so that the proportion of the time during which the switch is open is kept approximately constant. Thus, if there is a period during which a large number of high acceleration or high velocity signals appear from the receiver (for example is there is a very high noise level) the switch still remains closed for a certain proportion of the time period. This ensures that the tracking system never loses the target while also ensuring that false tracking due to target glint and multipath is minimized.A circuit is included so that, when the switch is open the antenna is not brought to a complete halt but rather is allowed to continue to move in the direction that it was moving before the switch was operated.
摘要翻译：在跟踪雷达系统中，目标闪烁和多路径有时会产生错误地指示目标的高加速度的信号。这些信号导致天线的视轴被驱动远离目标实际位于的方向。为了避免这个问题，来自接收机的接收信号通过开关被馈送，只要目标似乎具有高于阈值的加速度或速度，该开关就被打开。阈值变化，使得开关打开的时间的比例保持近似恒定。因此，如果存在从接收器出现大量高加速度或高速度信号的时段（例如，存在非常高的噪声电平），则开关仍然保持关闭该时间段的一定比例。这样可以确保跟踪系统不会丢失目标，同时确保由于目标闪光和多路径引起的错误跟踪最小化。包括一个电路，使得当开关断开时，天线没有完全停止，而是允许在开关被操作之前继续沿其移动的方向移动。

摘要： The present invention provides a method, system, and computer program product for the on-demand creation and distribution of customized dynamic contracts. At least one business opportunity is extracted from an opportunity database. For each extracted business opportunity, a credit score for a customer associated with the extracted business opportunity is obtained and a dynamically modifiable contract for the extracted business opportunity is generated. The dynamically modifiable contract is distributed to a contact associated with the extracted business opportunity, who presents the dynamically modifiable contract to the customer associated with the extracted business opportunity. The contact can modify the dynamically modifiable contract, if necessary, during negotiations with the customer, to provide a contract that is acceptable to the contact and the customer.

摘要： A method and system for updating a database structure. The database structure includes a dynamically changing list of control documents. A control document specifies tasks to be performed on the database structure. An agent finds an approved control document on the list such as by looking into a view of control documents. Processing the approved control document includes causing an execution of at least one task on the approved control document. Execution of a such task includes updating of the database structure, and may be implemented by the agent that found the control document or by another agent called by the agent.
