摘要： Data, such as video data, is encoded by identifying a data segment to be encoded. The data segment includes multiple frames. A bit-rate profile for encoding the data segment is generated. The bit-rate profile defines a number of bits associated with each frame in the data segment. Frames are encoded using the bit-rate profile. The bit-rate profile is updated periodically to incorporate past encoding statistics and compensate for any encoding bits deviations from the initial profile.

摘要： A leveling or plumbing device for indicating a line or a plane on a surface, such as wall or floor. The device includes a light beam generator that emits a light beam exteriorly of a body or housing. Level and/or plumb indicators, such as vials, are mounted to the housing for positioning the device in a predetermined orientation on the surface. The device includes a series of extendible and retractable engagement members, each of which defines an outer end having an adhesive. The adhesive engages the surface to releasably secure the device to the surface. The engagement members are biased inwardly toward a retracted position. The adhesive engagement of the engagement members with the surface maintains the engagement members in the extended position against the inward bias.

摘要： A method and apparatus for stirring a molten thixotropic aluminum alloy comprising a first solid particulate phase suspended in a second liquid phase so as to maintain its thixotropic character by degenerating forming dendritic particles into spheroidal particles while simultaneously equilibrating the melt temperature by quickly transferring heat between the melt and its surroundings. The melt is stirred by a magnetomotive force field generated by a stacked stator assembly. The stacked stator assembly includes a stator ring adapted to generate a linear/longitudinal magnetic field positioned between two stator rings adapted to generate a rotational magnetic field. The stacked stator rings generate a substantially spiral magnetomotive mixing force and define a substantially cylindrical mixing region therein.

摘要： A method of producing a semi-solid material without stirring, including heating a metal alloy to form a metallic melt, transferring a select amount of the melt into a vessel, nucleating the melt by regulating the transferring of the melt into the vessel, and crystallizing the melt within the vessel by cooling the melt at a controlled rate to produce a semi-solid material having a microstructure comprising rounded solid particles dispersed in a liquid metal matrix. In one form of the invention, a temperature-controlled shot sleeve is provided for receiving and cooling an amount of metallic melt at a controlled rate to produce the semi-solid material. The shot sleeve has a number of heat transfer zones adapted to independently control the temperature of the melt disposed adjacent various portions of the shot sleeve. The shot sleeve also includes a ram operable to discharge the semi-solid material directly into a die mold to form a near-net-shape part.

摘要： There is provided a continuous casting and rolling process for continuously producing a deformed fine grain solid metal composition suitable for semi-solid forming. The process is characterized by high throughput, continuity, and precise control of the process parameters, such as solidification rate, rolling temperature and speed and total deformation. The solidification rate is preferred to be in a range of 10 to 150° C./s, and the total deformation is controlled to be larger than a Mises effective strain of 2.3 to obtain a deformed fine grain structure with enough distortion energy. A method combining the continuous casting and rolling process of preparing semi-solid raw material with semi-solid forming of shaped articles is also disclosed.

摘要： A nonlinear terahertz (THz) spectroscopy technique uses a sample illuminated by two THz pulses separately. The illumination generates two signals BA and BB, corresponding to the first and second THz pulse, respectively, after interaction with the sample. The interaction includes excitation of at least one ESR transition in the sample. The sample is also illuminated by the two THz pulses together, with an inter-pulse delay τ, generating a third signal BAB. A nonlinear signal BNL is then derived via BNL=BAB−BA−BB. This nonlinear signal BNL can be then processed (e.g., Fourier transform) to study the properties of the sample.

摘要： A camera has a lens and aperture device for determining 3D information. A projector projects an optical pattern toward a surface. The camera has at least two off-axis apertures thereon, arranged to obtain an image of the projected pattern including defocused information. The camera is movable between different positions to image the surface from said different positions, and the projector is at a specified angle of at least 5° relative to said camera. A processor carries out a first operation using information received through the apertures to determine a pose of said camera, and to determine three dimensional information about the object based on a degree of deformation of said optical pattern on said surface indicative of a three dimensional surface. An embodiment projects a grid of laser dots and uses laser-dot defocusing for approximate Z and thus grid correspondence, which can greatly increase the working depth of the system.
