摘要： A method of controlling a flyback DC-DC converter includes using a primary control loop to monitor an auxiliary winding of a transformer for determining the amount of energy being transferred to a load. The voltage in the auxiliary winding is induced by current flowing in the secondary winding of the transformer. The primary control loop disables and enables the turning on of a power switch for driving the primary winding of the transformer, and detects the zero-crossing. The duration that the power switch is turned on is established by a secondary control loop using the output voltage for turning off the power switch for a new off phase. The flyback DC-DC converter further includes a fixed frequency oscillator having a frequency lower than the self-oscillating frequency of the converter. The power transferred from the primary circuit to the secondary circuit of the flyback transformer is controlled by introducing a delay on the turn-on instant of the power switch. This is with respect to a turn-on command generated during a self-oscillating functioning phase regardless of the mode of control of the converter. The turn-on command is based upon a zero crossing, a fixed frequency functioning phase, a rising edge of the signal generated by the oscillator, and as a function of the input variables of the primary and secondary control loops.
摘要翻译：控制回扫DC-DC转换器的方法包括使用主控制回路来监测变压器的辅助绕组，以确定正在传送到负载的能量的量。辅助绕组中的电压由在变压器的次级绕组中流动的电流引起。主控制回路禁用并启用用于驱动变压器初级绕组的电源开关，并检测过零点。通过使用输出电压关闭电源开关进行新的关断阶段的次级控制回路来建立电源开关打开的持续时间。反激式DC-DC转换器还包括频率低于转换器的自振频率的固定频率振荡器。通过在电源开关的导通瞬间引入延迟来控制从回扫变压器的初级电路传递到次级电路的功率。这是关于在自振荡功能阶段期间产生的开启命令，而不管转换器的控制方式如何。开启命令基于过零点，固定频率功能相位，由振荡器产生的信号的上升沿，以及主控制回路和次控制回路的输入变量的函数。

摘要： The method for authentication and electronic signature is of the private-key, challenge and response type between a user requesting an authorization, via, for example, a smart card and a controller—check terminal—supplying the authorization. To increase security of the authorization or authentication operations, the smart card comprises a chaotic generator generating user's acknowledgement code, which is compared with a comparison code generated by the check terminal using a chaotic generator which is the same.

摘要： The invention relates to a modular architecture of a cellular network for improved large-scale integration, of the type which comprises a plurality of fuzzy cellular elements (C.sub.m,n) interconnected to form a matrix of elements having at least m rows and n columns, the row and column numbers describing the location of each element. Each fuzzy processor is adapted for connection to other processors of the same type such that a parallel architecture of the modular type can be implemented.

摘要： A control device for a focusing system of a compact disk (CD) reader is provided. The control device uses fuzzy logic incorporated to the audio data processing system of the CD reader which is adapted to detect and segregate a light beam reflected by the surface of the compact disk from an incident light beam to the surface. The fuzzy logic control device receives a focus error signal and a derivative of the focus error. It then calculates, using appropriate membership functions, output signals to provide to a focusing servo-system of the CD reader to adjust the distance of the focal plane from the light beam detecting circuitry.
