摘要： Approximation of a function relating an independent to a dependent variable. A first resistance furnishes signals corresponding to the independent variable values at a plurality of first taps, a second resistance furnishes dependent variable signals at a corresponding plurality of second taps. A first and second contact arm respectively scan the first and second resistors simultaneously. A feedback circuit has an input terminal connected to the input furnishing the value of independent variable for which the value of dependent variable is to be found. It has a feedback input connected to receive the signals scanned by the first contact arm. Movement of contact arms is stopped when signal at first contact arm is equal to input signal. Signal at second contact arm then equal to desired value of dependent variable.

摘要： The signals of one or more engine operating parameters, such as r.p.m. and throttle valve vacuum are altered by function generators to correspond to the desired relationship between ignition timing and the parameters that are taken into account. These altered signals are added together and conducted to a comparator that receives as a second input a time and r.p.m. dependent signal from a saw tooh generator, the output of the comparator being fed to the ignition device.
摘要翻译：一个或多个发动机运行参数的信号，如r.p.m. 并且节气门真空度由功能发生器改变，以对应于点火正时和考虑到的参数之间的期望关系。这些改变的信号被加在一起并被传送到比较器，该比较器作为第二输入接收时间和r.p.m。来自锯齿发电机的相关信号，比较器的输出被馈送到点火装置。

摘要： A projector pivotal about an inclined axis casts upon a reflector mounted on a wheel a pattern, in the form of cross hairs, which reflector returns the image to a screen having therein two photo-diodes, the angular movement of the projector required to cause a cross hair to fall across the respective photo-diode is a measure of the caster or camber of the wheel. The projector is connected to the tab of a resistor, the voltage at the tab being indicative of the pivotal movement of the projector.
