摘要： A method is provided for obtaining images for use in displaying a three-dimensional illusion which includes the step of obtaining first and second images of a subject volume having foreground and background portions with the points of origin of those images located in a first plane which includes left and right points of origin of an observer of the subject volume and which is normal to the optical axis of that observer. The first and second points of origin are also respectively located equidistant above and below a first line interconnecting the left and right points of origin and are located along a second line which is normal to and bisects the first line. The first and second optical axes are aligned to converge in a second plane parallel to the first plane which includes the foreground portion of the subject volume within the field of view of the observer which is closest to the first plane. A support apparatus is provided for using one or two imaging devices in implementing the method of the subject invention and an alternative support apparatus is disclosed which incorporates a teeter-totter arrangement to automatically provide for maintenance of convergence of the optical axes in the second plane upon adjustment of the effective first and second points of origin above and below the first line connecting the left and right points of origin of the observer. Image recording medium containing images produced by the above method is also disclosed.

摘要： A single camera autostereoscopic recording system includes a single image recorder having a single optical path moved along a scanning path defined by a pair of rails and an arm movable on the rails substantially continuously for a plurality of scanning cycles. Alternatively a lens maintains the point of convergence. A path defining structure includes the ability to adjust the convergent point as well as the extent of travel along the scanning path or disparity of the images. The convergent point of the scanning path can be manually or automatically adjusted using a range finder. A unique driver structure including a reciprocating armature and stator provides scanning motion with reduced reactional forces. The degree of motion of the recorded images is used to adjust the amount of travel along the scanning path. Synchronization between the driver and the recorder is bi-directional for double exposures. The recorded image is adjusted in recording or in display as a function of the position in the scanning path.

摘要： Solid state emulations of vacuum tube power amplifier are shown for both high-power and low-power applications. The emulations include the screen grid and power supply effect of compression, the variable output impedance for reacting with a speaker load, power tube distortions, the limiting and bias shifting created by the power tube grids, and the bias shifting of the phase splitter. The high-power disclosure includes a current amplifier which may be linear or switching. The low-power disclosure simulates a vacuum tube amplifier with a speaker load in order to drive a master volume without diminishing the classic distorted tone. It has means to simulate the speaker impedance. The solid state emulation includes a gain control means which produce an unclipped region which may be divided into more or less distortion than one percent and two clipped regions having different output impedances or different frequency characteristics.

摘要： This switching amplifier is for driving inductive loads, stepping motors in particular. This amplifier uses dual threshold concept with improvements to the current feedback. These improvements compensate for errors in the feedback signals of the prior art. These improvements measure currents erroneously omitted or included in the feedback signal and add or subtract said measurements from said feedback to improve signal fidelity.

摘要： A control circuit for a stepping motor is provided which rotates the motor armature in such a manner as to minimize motor resonances while not appreciably reducing the motor torque at high speeds. The motor inherently possesses a non-linear transfer function of current to flux and the circuit includes means responsive to an input signal for developing a position command signal which is a sinusoidal waveform modified by the inverse of the motor transfer function. Further means are provided responsive to the position command signal for developing an energization signal for the stepping motor including means responsive to the position command signal and motor field current for terminating a motor energization cycle.
