  • Publication number: 20180006577
    Abstract: A control circuit is configured to sense an AC input voltage of a power factor correction (PFC) power circuit in a switching power converter, provide a control signal having an on-time and an off-time to at least one power switch of the PFC power circuit, and in response to detecting a peak voltage of the AC input voltage, increase the on-time of the control signal based on the sensed AC input voltage during an interval that begins with the peak voltage of the AC input voltage and ends with the next zero crossing following the peak voltage of the AC input voltage to improve a power factor of the switching power converter. Other example switching power converters, PFC power circuits and control circuits for controlling one or more power switches are also disclosed.

  • Patent number: 9546783
    Abstract: A modular luminaire which uses LED light sources. The basic frame comprises two end pieces compressed together by through bolts. At least one elongated heat sink is compressed between the end pieces. Each heat sink may bear a plurality of LEDs mounted on a printed circuit board which may have an integral metallic backplate, and is installed on one of the heat sinks with a layer of heat conductive grease therebetween. The heat sinks have fins projecting in three directions, the fourth direction being accounted for by the LEDs, and are rotatable about their longitudinal axes to adjust direction of light propagation. The heat sinks are arrayed in an arc, so that the outside heat sinks shield observers from direct glare from opposed heat sinks. Heat sinks may be extruded to form cooling fins and slots which may receive fasteners such as screws.

  • Patent number: 9274410
    Abstract: Methods and systems for generating masks for spacer formation are disclosed. As a part of a disclosed method, a predefined final wafer pattern is accessed, areas related to features in the predefined final wafer pattern are identified and a template mask is formed based on the identified areas for forming spacers on a wafer. Subsequently, a mask is formed for use in the removal of portions of the spacers to form an on wafer pattern that corresponds to the predefined final wafer pattern.

  • Patent number: 9202693
    Abstract: A method of forming an ultra-shallow junction in a semiconductor substrate. The method includes forming an amorphous region in a semiconductor substrate by performing a pre-amorphization implant step and implanting one or more dopants in the amorphous region by performing a monolayer doping step. The semiconductor substrate is then thermally treated to activate the implanted dopant in the amorphous region to thereby form an ultra-shallow junction in the semiconductor substrate. The thermal treatment can be performed without any oxide cap overlying the implanted amorphous region.
