Abstract: A closed loop tubular discharge assembly for an electrodeless light-emitting device and discharge reactor is disclosed. The discharge assembly comprises one or more tubular segments tubularly connected at their respective ends to form the closed loop tubular assembly, which hermetically encloses an ionizable gas. At least one of the one or more tubular segments forms a non-cylindrical, hollow-shaped tubular segment. In one embodiment, the non-cylindrical, hollow-shaped segment is formed by an internal tube at least partially enclosed within an external tube, forming a hollow-shaped discharge envelope enclosing the ionizable gas there between. When a discharge current circulates in the ionizable gas of the envelope, a hollow-shaped plasma is created in the envelope and surrounds the internal tube. This design has been shown to increase performance and provide several improvements over prior art devices.

Abstract: There is described a method and corresponding pulse generating device, for generating an output pulse signal having an output pulse duration. The method comprises: receiving at an input port an input pulse signal comprising an input pulse duration; duplicating the input pulse signal into a first digital pulse signal and a second digital pulse signal each comprising the input pulse duration; delaying at least one of the first and the second digital pulse signals by a time delay to obtain respectively a first and a second delayed digital pulse signal, a time delay difference between the first and the second delayed digital pulse signals being substantially equal to the output pulse duration; logically combining the first and the second delayed digital pulse signals to generate the output pulse signal with the output pulse duration smaller than the input pulse duration; and outputting the output pulse signal at an output port.
