    摘要： An apparatus for loading, chamfering and unloading a ceramic or ceramic/polymer substrate for electronic components. An automatic part loader moves substrates in a row as a unit, using a frangible pin to push the parts. The part loader separates the first of the substrates from the rest, and a load pedestal pushes the first substrate up into a loading/unloading nest. The load pedestal is mounted on rods so that the substrate may move laterally to center itself in the nest. The nest then rotates to load the substrate onto a movable process pedestal. The chamfering apparatus includes a pair of spaced, rotatable cutting spindles for chamfering edges and corners on the substrate. The cutting spindles include: i) separate top and bottom edge cutters for simultaneously chamfering top and bottom of edges of a substrate secured on the carrier as the substrate passes between the spindles and ii) corner cutters for simultaneously chamfering corners of a substrate secured on the carrier as the substrate contacts the spindles. The pedestal rotates the substrate about an axis normal to the plane of the substrate and moves the substrate in a direction normal to the plane of the substrate to present unchamfered edges and corners to the cutting spindles. A disc brake on the process pedestal may be actuated to prevent rotation of the substrate during chamfering. An enclosure surrounds the substrate, chamfering cutters and process pedestal during chamfering and utilizes the air flow supplied by the rotating cutters to propel chips into a particle collector.

    摘要： Acoustic dialers are widely used to dial telephone numbers by generating a pair of DTMF tones for each key being depressed. Non-linearities in telephone systems, acoustic dialer loudspeakers, and telephone microphones may cause interfering tones to be produced due to mixing of generated DTMF tones. These interfering tones are especially problematic when they are near the frequencies of the DTMF tones and have similar amplitudes. When these interfering tones are received by a receiver decoder, the decoder may be unable to distinguish the interfering tones from the DTMF tones, and consequently the decoder may reject the DTMF tones received. The present invention prevents these types of rejections by generating a supplemental tone in addition to the normal DTMF tones. This supplemental tone attenuates the interfering tones so that receiver decoders can distinguish the interfering tones from the DTMF tones.

    摘要： A patterning device, including alignment targets having alignment features formed from a plurality of diffractive elements, each diffractive element including an absorber stack and a multi-layered reflector stack is provided. The diffractive elements are configured to enhance a pre-determined diffraction order used for pre-alignment and to diffract light in a pre-determined direction of a pre-alignment system when illuminated with light of a wavelength used for the pre-alignment. The diffractive elements may occupy at least half of an area of each alignment feature. The diffractive elements may be configured to enhance first or higher order diffractions, while substantially reducing zeroth diffraction orders and specular reflection when illuminated with a wavelength used for reticle prealignment. The dimensions of each diffractive element may be a function of a diffraction grating period of each alignment feature.

    摘要： A high pressure liquid chromatography (HPLC) capillary column device, system and method for processing a HPLC sample with a cartridge housing a packed capillary column; at least one inlet connection to the capillary column for a sample fluid; and at least one outlet connection from the capillary column for the sample fluid. The outlet connection is able to accommodate either a spray tip for atomizing the sample fluid or a transport tube for transporting the sample fluid from a spray tip column to a spray tip. Inlet connections enable supply of electrical power to the capillary column through electrical connections disposed within the cartridge housing; and gas for evaporating the sample liquid is supplied to at least one outlet connection from the capillary column for the sample fluid through a gas supply line within the cartridge housing. The temperature of the sample liquid can be controlled through a heat connection.

    摘要： In general, in one aspect, the invention relates to a method for static analysis. The method includes: obtaining source code; constructing a control flow graph (CFG) corresponding to the source code, by identifying control structures within the source code, creating a set of graph nodes of the CFG, and creating a set of directed graph edges of the CFG connecting the set of graph nodes; assigning a first Boolean flow value to a selected node of the set of graph nodes; backward traversing the CFG from the selected node to a target node; computing, by a computer processor and while backward traversing the CFG, disjoint predicate expressions representing flow values at the set of directed graph edges; computing, based on the disjoint predicate expressions, a resulting disjoint predicate expression; and identifying, based on the resulting disjoint predicate expression, a potential program property in the source code.
