Title: Digital scanning converter
Inventor: REIMONDO JIEI BERII
IPC: G01S7/52
Filed: 1982-05-15
Abstract: A digital scan converter is disclosed wherein signal information supplied by a sector scanning surveillance system relative to a polar coordinate system is converted to a signal for driving a television-type display or other Cartesian coordinate device by: (a) sampling the signal associated with each consecutive scanning path of the surveillance system at a rate determined by the azimuthal angle that defines the scanning path of interest; (b) storing each set of signal samples as a column of data in a rectangular memory array; (c) accessing the stored data on a row-by-row basis; and (d) utilizing a previously determined mapping strategy to cause each accessed signal sample to form a segment of a line of display within the Cartesian-formulated display devices so that the length of the segment formed by each signal sample is determined by the row and column address of the storage location that is associated therewith when forming a television compatible signal, each signal sample dictates video signal level during a portion of a corresponding horizontal sweep period that is determined by the mapping strategy.

Abstract: PURPOSE:To enable the grade start of an electric rolling stock to be performed safely and exactly, by releasing an air brake after the starting thrust of a non-synchronous linear motor is sufficiently generated on the start of an electric rolling stock. CONSTITUTION:By the contact point of a start command relay SR, start command is directed to a gate control circuit GCB for input for a variable-voltage and variable frequency inverter VVVF, and by the variable-voltage and variable- frequency inverter VVVF, proper three-phase AC voltage and frequency controlled so that a starting thrust may be generated on non-synchronous linear motors LIM1-LIM4 are fed.
