Abstract:
A liquid-based gravity-driven etching-stop technique for controlling structure dimension is provided, where opposite etching trenches in cooperation with an etching-stop solution are used for controlling the dimension of a microstructure on the wafer level. In an embodiment, opposite trenches surrounding the microstructure are respectively etched on sides of the wafer, and the trench depth on the side of the wafer, on which the microstructure is, is equal to the design dimension of the microstructure. Contrarily, it is unnecessary to define the trench depth on the back-side of the chip. In the final step of the fabrication process, when the device is etched, such that the trenches on the sides communicate with each other to separate the microstructure from the whole wafer automatically and thereby shift from the etchant into the etching-stop solution to stop etching.
Abstract:
An apparatus is provided for feeding fabric workpieces one at a time from the top of a stack of like workpieces having a first rough side and a second smooth side, the workpieces being stacked with alternating sides up. A computer controlled picker is used to separate the top workpiece from the remaining workpieces in the stack, and for depositing the workpiece on a downstream conveyor. An ultrasonic face detector is mounted above the first conveyor for determining whether the side of the workpiece facing the face detector--the top surface--is relatively rough or relatively smooth. A pivoting feeder/inverter is provided at the end of the first conveyor. If the workpiece has the desired side up for subsequent sewing operations, the inverter/conveyor is placed in a first position so that the workpiece is directed into a sandwich belt type conveyor which will not change the orientation of the workpiece. If the workpiece has the desired side down, the feeder/inverter is pivoted to a second position to enable the workpiece to enter an inverter conveyor which will rotate the workpiece 180 degrees about an axis along the direction of travel to place the workpiece in the correct orientation for the subsequent sewing operation. Thus, this apparatus takes all of the fabric workpieces from a stack in which the sides facing up alternate, and automatically places all of them in the same orientation prior to arrival at a sewing station.
Abstract:
A method for animating fibers in a computer-based animation process, the method comprises: obtaining a fiber cache comprising a plurality of fibers, each of the plurality of fibers comprising a plurality of fiber vertices; obtaining one or more guides, each of the one or more guides comprising a plurality guide vertices; and determining binding information to bind the one or more guides to the fiber cache. Determining the binding information comprises, for each fiber of the fiber cache: associating the fiber with one or more nearby guides; and, for each of the one or more associated nearby guides: associating each fiber vertex with a nearby guide vertex; and determining, for each fiber vertex, a displacement vector between the fiber vertex and the associated nearby guide vertex.

Abstract:
An automatic garment inspection and measurement system can create a two-dimensional or three-dimensional electronic representation of an object. This electronic representation can then be combined with other electronic representations to create a database of measurements from which standard patterns can be generated for use in manufacturing garments. The electronic representation can also be used to compare the manufactured object it represents to an ideal representation in order to determine if the object's measurements are within a predetermined tolerance of the ideal representation. A machine vision system is used to capture an image of the object and convert that image into a digital representation which can then be added to a database to be used to compile an ideal pattern or can be compared to an already existing ideal image to determine if the object is the correct size.
Abstract:
A method for manipulating vertex positions of one or more simulated hair strands based on user input while preserving shape details of the one or more simulated hair strands. The method comprises receiving a displacement vector and a region as input and identifying first consecutive groups of vertices of a first simulated hair strand within the region. For each first consecutive group of vertices within the region, the method comprises finding the average vertex position, determining the closest vertex of the consecutive group of vertices to the average vertex position, determining a new positional constraint based on the closest vertex and the displacement vector and determining new vertex positions for the first simulated hair strand by running a constraint enforcement process constrained by the new positional constraint for each consecutive group of vertices and one or more shape-preserving constraints.
Abstract:
A field emission device has pixels with cathode and anode provided on the same plane, so that electrons directly penetrate an independently provided fluorescent powder layer to produce light, giving the display the advantages of easy focusing, no dark spots, high brightness, and enhanced light emitting performance. Since the light produced by the fluorescent powder layer is not blocked by the anode, the problem of charge accumulation on the fluorescent powder layer is avoided, and it is not necessary to use expensive light-transmittable conducting glass as the anode. With the cathode and the anode located at the same plane, it is not necessary to use a high precision spacer to maintain a fixed distance between the cathode and the anode, enabling the device to be manufactured at reduced cost and high good yield.

A scrap device for a food processor is connected to the cap of the processor and the cap includes a feeding tube which is located above the grinding plate of the processing unit. The grinding plate includes blades for grinding fruit or food and is driven by a motor. A filter extends from a periphery of the grinding plate and the scrap plate keeps a proper a gap between an inside of the filter and the scrap device. The scrap plate is stationary and the filter is rotated together with the grinding plate so that the scrap plate remove the debris attached on the filter which operating the food processor.
