    Abstract: An anti-cycling luminaire control system may detect repeated lamp-off conditions and interrupt power to the lamp and provide an indication of lamp cycling after a predetermined number of lamp-off conditions has been detected. The control system also provides a cool-off period after a lamp-off cycling event is detected during which time restarting of the lamp is inhibited. If the lamp does not restart after multiple restart attempts and cool-off periods, the system determines that a fault condition exists, and may provide a fault alert. The system may provide for shut-off or dimming of the lamp during the night after a portion of the night has passed. This delayed turn-off may be varied according to the length of the night. Starting and dimming the lamp at a zero voltage crossing of the line current can reduce stress on luminaire and control system components and reduce maintenance.

    Abstract: The invention is related to a cathode ray tube of the index type (1). Tracking elements (16,18) from a tracking structure flank, preferably above and below each phosphor element (20), being provided on an inner surface of a screen (10). A tracking signal that is derived from response signals from the tracking elements, is used to keep the electron beam (7,8,9) on the right phosphor element. In the index tube according to the invention a part of the tracking lines is provided with gaps (30, 30′). The gaps generate an interruption in the tracking signal. This interruption can inter alia be used to derive the precise position of the electron beam (7,8,9) on the screen (10), especially during the star-up phase of the tube.

    Abstract: A digitally-controlled vertical S linearity correction with a constant amplitude without using an AGC. To preserve line spacing between horizontal lines toward a top and bottom of a screen a third order correction voltage Vcube is applied to a sweep voltage Vosc. A constant current decoder determines an amount of appropriate correction current, which is employed to generate a sweep voltage with modified amplitude due to S correction and one without the modified amplitude. The sweep voltage with constant amplitude is employed to generate Vcube. Vcube is then applied to the sweep voltage along with a compensated amplitude component of the sweep voltage, such that a reduction in the amplitude caused by the S correction is compensated in the output voltage Vout. The compensation of the output voltage amplitude prevents a size reduction of the displayed picture on the screen without employing an iterative auto-align process.

    Abstract: A dynamic focus amplifier for generating a dynamic focus voltage for a focus electrode for a cathode ray tube at a capacitive load includes a source of a periodic signal at a horizontal deflection frequency. A pull-down transistor is responsive to the periodic signal and coupled to the capacitive load for producing, in accordance with the periodic signal, a first portion of the dynamic focus voltage that decreases, during a first portion of a period of the periodic signal. A storage capacitor is coupled to the capacitive load for replenishing a charge stored in the storage capacitor from a charge stored in the capacitive load to develop a control voltage in the storage capacitor. A pull-up transistor is responsive to the control voltage and coupled to a source of a high voltage and to the capacitive load for producing from the high voltage a current that is coupled to the capacitive load. The current develops a second portion of the dynamic focus voltage that increases, during a second portion of the period of the periodic signal, and stores the charge in the capacitive load.
