Abstract: An ion source capable of extracting a ribbon ion beam with improved uniformity is disclosed. One of the walls of the ion source has a protrusion on its interior surface facing the chamber. The protrusion creates a loss area that serves as a sink for free electrons and ions. This causes a reduction in plasma density near the protrusion, and may improve the uniformity of the ribbon ion beam that is extracted from the ion source by modifying the beam current near the protrusion. The shape of the protrusion may be modified to achieve the desired uniformity. The protrusion may also be utilized with a cylindrical ion source. In certain embodiments, the protrusion is created by a plurality of mechanically adjustable protrusion elements.

Abstract: The invention relates to an incorporation of a current limiting/regulating circuit on a luminaire board for ensuring that the luminaire board will automatically operate at its desired current after a replacement. Since the current control at the luminaire board causes an initial mismatch between the current supply of the driver and the demand of the luminaire board, the driver output voltage will drift towards the maximum output voltage of the driver. When the maximum output voltage is reached, the driver is configured to operate in constant-voltage (CV) mode, sense the output current and reduce its output current to the same value as consumed by current-controlled luminaire board. Alternatively, the driver may gradually reduce the setpoint of the output current until it just leaves the CV mode and stay at that setpoint. In this way, the driver will automatically operate at the correct current of a newly installed luminaire board without any action from the user.

Abstract: The present application discloses an identification circuit for a power-line carrier signal. During signal transmission on a power line, the amplitude change and duration of a voltage signal on the power line are identified and then decoded into corresponding data, so as to reduce dependency on a power supply voltage during signal identification, and prevent the signal identification rate from decreasing as a result of an increase in the transmission distance, thereby reducing requirements for a system power supply.

Abstract: Presented are average current mode control systems and methods for driving a load with a constant current. In embodiments, this is accomplished when, in response to a zero-current detection circuit detecting a zero current condition in the load current, a compensation circuit is disconnected from a first error amplifier to enable that error amplifier to provide a first voltage to a second error amplifier.
