Abstract: A circuit for reading fused data, an image sensing apparatus, a method of reading fused data and a method of manufacturing a circuit for reading fused data. The circuit includes a fuse and a capacitive component configured to provide a data input signal to a data input node of a one bit data storage unit and a signal delay component configured to provide a delayed signal to a clock input terminal of the one bit data storage unit. The method of operating the circuit includes applying a signal to the fuse and to the signal delay element, delaying the signal in the delay element, providing a delayed signal from the delay element to a clock input of a one bit storage element, and providing the signal from the fuse and the capacitive component to a data input of the one bit storage element.

Abstract: A discharge vessel with a ceramic wall is filled with inert gas and metal and is ignited and operated by an electronic circuit including a half bridge converter with an LC circuit which, when the lamp is not ignited, enters an oscillation state near a resonance frequency which lies near the third harmonic of the switching frequency of the half bridge converter. The vessel encloses a cylindrical discharge space of diameter D and length L, wherein L.ltoreq.D.ltoreq.1.2 L.
