    • An imaging includes an image acquisition module which has an image sensor and a first lens system, having a focal plane, for imaging an object onto the image sensor, a display module which displays the image captured by means of the image acquisition module such that a user can perceive it with one eye, and a control unit. A measuring module is provided to the control unit for measuring the accommodation state (B1(t)) of the eye of the user. The control unit adjusts the position of the focal plane of the first lens system on the basis of the measured accommodation state (B1(t)) and, at the same time, adjusts displaying of the image by means of the display module on the basis of the measured accommodation state (B1(t)) such that the user can perceive the displayed image in sharp definition with his eye having the measured accommodation state (B1(t)).

    • The regulated output voltage of a voltage regulator is maintained up to a current limit, Ilimit, then as the load impedance continues to decrease the output current does not increase past the current limit, Ilimit, but rather the output voltage decreases forcing the output current to also decrease to satisfy Ohm's Law: IOUT=VOUT/ZLoad. When the output voltage drops below the regulated voltage value because of current limiting the voltage regulator shifts from a current limit mode to a current foldback mode wherein the output current decreases with the decrease in output voltage until the output current reaches a current foldback minimum, Ifoldback, at an output voltage of substantially zero volts. As the load impedance increases so will the output voltage and current until the output voltage is back at substantially the regulation voltage value, and the output current is less than or equal to the current limit, Ilimit.
    • 电压调节器的稳压输出电压保持在电流限制Ilimit,因此当负载阻抗持续降低时,输出电流不会超过电流限制Ilimit,而是输出电压降低迫使输出电流 也降低到符合欧姆定律:IOUT = VOUT / ZLoad。 当输出电压由于电流限制而降低到调节电压值以下时,电压调节器从电流限制模式转换到电流折返模式,其中输出电流随着输出电压的降低而减小,直到输出电流达到当前折返最小值Ifoldback ,输出电压基本为零伏特。 当负载阻抗增加时,输出电压和电流将直到输出电压恢复到基本上的调节电压值,并且输出电流小于或等于电流限制Ilimit。

    • An orientation measuring device with a plurality of precision tooled grooves, indentations or the like. Two precision tooled adaptor bodies, preferably of cylindrical shape, are removably mountable in the indentations, where appropriate, for a given measuring task. The adaptor bodies are held in place by, e.g., magnets. The device is capable of determining the spatial orientation of rolls, bars, hollow or solid cylinders, ranging from small to large diameters by appropriately selecting in which of the grooves or indentations the adaptor bodies are mounted.

    • A differential input operational amplifier has a voltage clamp differential transistor pair coupled to an input differential transistor pair of the operational amplifier. The voltage clamp differential transistor pair limits the output voltage of the operational amplifier by taking over control of the operational amplifier circuits from the input differential transistor pair as the output voltage approaches a clamp voltage value. A reference voltage may be used to set the output voltage at which the input differential transistor pair will be clamped by the voltage clamp differential transistor pair. Below the clamp voltage, operation of the input differential transistor pair will not be affected. At the clamp voltage the input differential transistor pair will no longer control the output of the differential amplifier, rather the voltage clamp differential transistor pair will control the maximum voltage output of the differential amplifier. Both positive and negative limiting of the operational amplifier output voltage may be accomplished.
