摘要： A method and apparatus for spatially filtering a signal set to enhance interface echoes representing a borehole configuration. The spatial filtering technique provides information regarding the various interfaces formed between materials in the borehole environment, as well as thicknesses of the various materials present in the borehole. Further, the presence of channels formed during the cementing procedure are detected.

摘要： A charge pump voltage regulating circuit which uses a constant current generator and a second current generator, controlled by the output voltage of the charge pump circuit. The current from the constant current generator is divided between the input to a current controlled oscillator and the second current generator. When the output voltage of the charge pump circuit increases the current in the second current generator increases, the current flowing into the current controlled oscillator decreases, the frequency of the clock signals supplied to the charge pump circuit decreases, and the output voltage of the charge pump circuit decreases. When the output voltage of the charge pump circuit decreases the current in the second current generator decreases, the current flowing into the current controlled oscillator increases, the frequency of the clock signals supplied to the charge pump circuit increases, and the output voltage of the charge pump circuit increases.

摘要： Methods for removing particles from a wafer for photolithography. A method is provided including providing a semiconductor wafer; attaching a polyimide layer to a backside of the semiconductor wafer; and performing an etch on an active surface of the semiconductor wafer; wherein particles that impinge on the backside during the etch are captured by the polyimide layer. In another method, includes attaching a layer of polyimide film to a backside of a semiconductor wafer; dry etching a material on an active surface of the semiconductor wafer; depositing of an additional layer of material on the active surface of the semiconductor wafer; removing the layer of polyimide film from the backside of the semiconductor wafer; patterning the layer of material using an immersion photolithography process to expose a photoresist on the active surface of the wafer; and repeating the attaching, dry etching, depositing, removing and patterning steps.

摘要： A stepped light guide has an incident surface, an emitting surface and a stepped reflecting structure. The emitting surface is adjacent to the incident surface. The stepped reflecting structure is adjacent to the incident surface, faces the emitting surface and has a proximal end, a distal end, multiple planar surfaces and multiple inclined surfaces. The proximal end is adjacent to the incident surface. The distal end is opposite to the proximal end. The planar surfaces are parallel to and separated from the emitting surface by a depth, the depth being gradually reduced from the proximal end to the distal end. The inclined surfaces are formed between every two adjacent planar surfaces. The light guide effectively changes a linear or point light source into a surface light source having uniform illumination.

摘要： A diaper having wetness detectors, a system thereof and a wetness detecting method are adapted to detect the excreting status of an animal. The diaper includes a first set of contacts and a second set of contacts which are constituted by conductive material. The first set of contacts and the second set of contacts are respectively disposed on proximal and distal area of the diaper corresponding to the excretory organ of the animal. A detecting circuit detects the electrical property of the first set of contacts and the second set of contacts and then determines the excretion status of the animal to be a reference for a caregiver.
