摘要： System and method for protecting a power converter. The system includes a first comparator configured to receive a threshold signal and a first signal and to generate a comparison signal. The first signal is a sum of a second signal and a third signal, and the third signal is associated with an input current for a power converter. Additionally, the system includes a pulse-width-modulation generator configured to receive the comparison signal and generate a modulation signal in response to the comparison signal, and a switch configured to receive the modulation signal and control the input current for the power converter. An amplitude for the first signal becomes larger if an amplitude for the input voltage becomes larger. The second signal is generated by receiving an input voltage for the power converter, converting the received input voltage to a fourth signal, and converting the fourth signal to the second signal.

摘要： The radiation beam of discrete light source such as LEDs is shaped by a cylindrical lens and a spherical lens to form two perpendicular narrow lines to illuminate a surface. The first line is projected onto a sample surface to improve illumination efficiency, and the second line is projected onto a pupil plane of an imaging lens to improve illumination uniformity. The layout of the LED chip is optimized to match the aspect ratio of the imaging detector. Multiple LEDs at different wavelengths are combined to improve sensitivity. The full surface of the sample is inspected through the relative motion between the sample and the optics.

摘要： Spatial filtering is disclosed that improves the signal to noise ration of a sample inspection system of the type having a detector and collection optics that receive radiation scattered from a point on a sample surface and direct the scattered radiation toward the detector. The spatial filtering may screen the detector from substantially all of the forward-scattered radiation from back-scattered radiation that is scattered in a at an elevation angle less than about 45° with respect to a normal to the surface. Forward scattered noise is screened from the detector while backscattered signal reaches the detector. Programmable spatial filters may be used to selectively block scattered noise due to surface roughness while transmitting scattered signal due to surface defects.

An injection chamber receives hot injection gases. A non-circular stator is coupled to the injection chamber, and the non-circular stator is designed for maximum expansion of the hot injection gas. A rotor is coupled to the non-circular stator and accelerates when the hot injection gas expands, resulting in a conversion of hot injection gas to rotary mechanical power.
