Patent EP-0143405-A2 (EP)
Inventor: HIROSE SYUNICHI
IPC: H02M7/155
Filed: 1984-11-15
Abstract: A phase detecting apparatus comprises a first PLL and a second PLL having a response time shorter than the response time of the first PLL. An AC voltage signal produced by the first PLL which is in phase with the detected AC voltage except until the expiration of the response time of the first PLL after an abrupt change in the phase of the detected AC voltage is normally applied to the second PLL. Until expiration of the response time of the first PLL after rising of the detected AC voltage to a certain level, the detected AC voltage is applied, in place of the AC voltage signal produced by the first PLL, to the second PLL. The second PLL provides a digital signal indicative of the phase of the detected AC voltage.

Abstract: @ A colour cathode ray tube (54) has raster scan colour zones defined by X and Y positional signals derived from a stroke vector generator (51) and stored in a digital memory. Raster scan and stroke vector displays are alternately presented in a hybrid display. The display face (10) of the tube is scanned by a plurality of raster lines and a colour transition point is defined by the intersection of a stroke vector with a raster line. The X and Y addresses of the intersection points define the raster line, pixel element, and colour at the transition point. The system is arranged so that the X and Y addresses are provided by the stroke vector generator (51) in synchronous relation with the colour transition points, and read into memory during the stroke vector refresh period. During the raster scan refresh period, the memory contents are recalled in synchronism with the raster scan, passed through a digital-to-analogue converter, and then applied to the display tube to provide filled- in colour zones superposed on the stroke vector display. The reduced memory requirements and controller access time permit dynamically rotating symbology in a synthetic display for aircraft flight instrumentation.
