摘要： An improved system for measuring and signaling the magnitude and angular location of unbalance in a rotatable workpiece, characterized especially by a non-contacting sine-cosine wave generator which imposes no mechanical inertia or self-contained unbalance on the system while the workpiece is rotationally driven for testing, and which is immune from the adverse effects of variations in the speed of the rotational drive.

摘要： An improved vector generating electrical system is provided for forming the mathematical representation of a vector. The system is particularly useful for drawing images in any desired pattern on the screen of a cathode-ray tube, whereby the images are composed of a multitude of vector lines having horizontal and vertical components. With the improved system of the invention, the vector drawing speed is not constant, but is an exponential function. One embodiment utilizes suitable switching gates to adjust the time constant of the exponential function at discrete points during the drawing stroke to reduce the vector drawing time as much as possible. In a second embodiment the time constant is changed in an infinite resolution system.

摘要： A method of producing a scan on a CRT which will follow a predefined path, as viewed by an observer, by generating the two voltages to drive the scanning spot with two polynomials (which are functions of two variables describing the desired spot position as a function of time,) representing the path, the coefficients of said polynomials being found by obtaining known values of the voltages and variables for an array of points on the CRT and performing a numerical analysis on said array.

摘要： An electronic system for converting an analog input signal into typical synchro or resolver-type signals. The input voltage is compared with function waveform such as a ramp voltage of a given frequency which is synchronized to the alternating current and power source. When the input voltage balances out the ramp voltage, a sampling pulse is generated. With this pulse, the instantaneous values of two-power frequency sine waves are measured and held in sample-and-hold circuits. The two-power frequency signals are phase-locked to the ramp voltage and can be derived from a biphase oscillator. Coupled to the sample-and-hold circuits are power frequency modulators and output amplifiers with active filters which provide a pair of synchro or resolvertype output signals. The ramp voltage generator and sine wave generator are commonly utilized in the case of a plurality of converter channels.

摘要： A network for sequencing the generation of parts for the display of an electronically generated image using signals established and controlled according to the viewing angle of the display subject. For sequencing purposes, parts of the display are assigned to sets of three groups connected in a closed loop. Depending upon the angle of viewing the display subject, selective transmission of enabling signals determines which group will start the sequence and in which order the other two groups will follow.
