A method and system for measuring stray light for use in an exposure apparatus uses an image sensor to be disposed at a wafer level in the exposure apparatus. The stray light is measured by preparing a reference pattern and a measuring pattern on a reticle. The reference pattern includes a light shielding region having first open regions for transmitting light to a center of an active region of the image sensor. The measuring pattern includes a light shielding region having second open regions for transmitting light to a periphery of the active region. A first intensity of light reaching the active region after being filtered by the reference pattern and a second intensity of light reaching the image sensor after being filtered by the measuring pattern are measured. The intensity of the stray light is evaluated by a difference between the first and second light intensities.

A system and method for reducing visible speckle in images displayed using coherent light. In an embodiment, a system for displaying images includes a light source to produce coherent light, an array of light modulators optically coupled to the light source and positioned in a light path of the light source after the light source, and a controller electronically coupled to the array of light modulators and to the light source. The light source includes a coherent light source, and a first digital micromirror device (DMD) having a first plurality of micromirrors. The first DMD is optically coupled to the coherent light source and positioned in a light path of the coherent light source after the coherent light source. The first DMD directs coherent light by moving the micromirrors of the first plurality of micromirrors through a first range of tilt angles substantially continuously.

A combustible charcoal fuel package is disclosed which includes an outer wrapper, preferably formed from burlap or other similar woven material that encloses large pieces of charcoal material, medium pieces of charcoal material and smaller pieces of charcoal material coated or otherwise soaked in a vegetable wax to form an aggregate. The aggregate is disposed at or near the bottom of the burlap wrapper, with the medium-size pieces of charcoal material disposed thereon with the larger pieces of charcoal material disposed on top of the medium-sized pieces of charcoal material. Preferably, all charcoal materials are fabricated from all-natural charcoal logs fabricated from compressed charcoal particles without the use of odor causing binders.

This device is a wireless tailgate braking and turn signal System, which will temporarily enable a driver of a vehicle to have taillights and/or a blinker system for emergency situations. This would insure road safety in all types of conditions, both in terms of extremes in temperature and inclement weather.

A system for controlling engine air/fuel ratio includes an engine, a compressor having an inlet receiving air. The compressor discharges air to the engine intake. A recirculation path is provided from the compressor discharge to the compressor inlet. A controllable valve is located along the recirculation path. A controller is programmed to control the valve to vary the air flow to the engine intake, thereby controlling the air/fuel ratio. Various applications for the compressor recirculation arrangement are possible.

The invention relates to the field of auto interior decoration and in particular relates to an artificial leather treating agent, polyvinyl chloride artificial leather, a preparation method and an application thereof. According to the artificial leather treating agent, acrylic acid modified waterborne polyurethane per 100 parts by weight contains 5-10 parts by weight of an auxiliary agent, wherein the auxiliary agent comprises the following components in parts by weight: 3-8 parts of a curing agent, 0.01-0.2 part of a defoamer, 0.5-1.5 parts of a flatting agent and 8-15 parts of a feeling agent. The viscosity of the artificial leather treating agent is that the time of the artificial leather treating agent flowing out through a bottom hole of a #3 Ford cup is 30-40s. The artificial leather treating agent is coated to the surface of a base layer to form a treatment layer, wherein the coating amount is 45-70g/m<2>; and a semiproduct forming the treatment layer is foamed and knurled to obtain the polyvinyl chloride artificial leather. The polyvinyl chloride artificial leather applied to an automobile interior decorative material has the characteristic of reducing the frictional noise and meets the requirement of frictional noise of an interior decorative product.

Composite or plastic molded articles used in a grand piano piano action. The articles make up a piano action with less dynamic mass which is, thus, more responsive. In addition, the new action provides the extremely valuable collateral benefits of increased efficiency of manufacture and maintenance. The invention also provides the capability to achieve true half stroke design in both the sharp and white keys at the same time. Additionally, the application discloses a universal composite grand piano piano action that is capable of being installed into any brand of grand piano.

A solid-state light source (SSLS) with light modulation control is described. A SSLS device can include a main p-n junction region configured for recombination of electron-hole pairs for light emission. A supplementary p-n junction region is proximate the main p-n junction region to supplement the recombination of electron-hole pairs, wherein the supplementary p-n junction region has a smaller electron-hole life time than the electron-hole life time of the main p-n junction region. The main p-n junction region and the supplementary p-n junction region operate cooperatively in a light emission state and a light turn-off-state. In one embodiment, the recombination of electron-hole pairs occurs in the main p-n junction region during a light emission state, and the recombination of electron-hole pairs occurs in the supplementary p-n junction region light during the light turn off-state.

First integrating circuits 110 convert electric currents from one group of photosensitive portions electrically connected to each other in a plurality of pixels arranged in a first direction into voltages, and output the voltages. First S/H circuits 130 hold and output the voltages outputted from the first integrating circuits 110. A first maximum value detecting circuit 140 detects the maximum value of the voltages outputted from the first S/H circuits 130. First level shift circuits 170 shift levels of the voltages outputted from the first S/H circuits 130. A first A/D converter circuit 180 sets a range from the maximum value detected by the first maximum value detecting circuit 140 to a value smaller than the maximum value by a predetermined value as an A/D conversion range, and converts the voltages outputted from the first S/H circuits 130 into digital values within the A/D conversion range.
