摘要： Device for increasing the resolution of an angle measuring instrument using two pairs of rotating discs each provided with measuring indicia where one pair of discs has one more measuring indicia per unit length than the other pair. The discs provide vernier-like pulse trains wherein a delay of less than a predetermined amount between corresponding pulses of the two pulse trains indicates angular measurement. This delay is determined by using a pulse of the first pulse train to conduct high frequency counting pulses into a counter having a limited capacity that produces an output pulse when such capacity is exceeded. A logic circuit connected to the counter determines whether a pulse from the second pulse train appears before the counter capacity is exceeded whereupon the counter is interrupted, the indication of the counter at that time being the interpolated position indication.

摘要： A system for producing a reference value for a desired value of an independent variable of a nonlinear function for which, in the range of interest, the dependent variable varies regularly and unidirectionally with variations of the independent variable in a given direction, according to a known function, the reference value being produced by simultaneously determining the values of the dependent variable for successive pairs of independent variable values which differ by a selected amount, while varying the independent variable, and producing an indication of one of the independent variable values of that pair at which a given ratio exists between the dependent variable values, this ratio corresponding to a predetermined independent variable difference between such one independent variable value and the desired value.

摘要： Described is an electro-chemical pulse counter suitable for use as a vehicle odometer. The pulse counter may include a number of identical stages, each of the stages having an electro-chemical cell. When DC current pulses pass between cell electrodes, metal is transferred from one electrode to another and this changes the cell''s electrical resistance. If the DC pulses are related to distance traveled by a vehicle, the cell resistance is proportional thereto. This is detected by an AC signal applied to the electro-chemical cell. The AC signal does not change the cell''s resistance.

摘要： In the pulse measuring apparatus disclosed herein, a pulse input signal is applied to a plurality of discriminators to provide respective timing signals when the signal amplitude passes respective preselectable levels. Signals having amplitudes which are functions of the intervals between selected ones of these events are then provided by performing time-to-pulse-height conversions in real time. As the means performing these conversions typically cannot provide continuing or stored signals, a plurality of means are further employed to provide continuing signals representative of the respective intervals.

摘要： A departure gate for sporting runs includes two riser members forming an outlet, each riser member bearing a device comprising a bar arranged to be angularly movable, the bar extending at least halfway over the width of the outlet. Each device includes an electrical contractor controlled by the bar and operated thereby as soon as the bar has traversed a predetermined angle (.alpha.). The contactors are coupled in a manner such that an electrical output signal is produced only when at least one of the bars has traversed the angle .alpha.. The gate minimized or eliminates the influence that the starting position of the contestant may have on his result.
