  • Patent number: 8379080
    Abstract: According to various illustrative embodiments, a device, system, and method for reducing stereoscopic phase-lag distortion under motion in a 3-dimensional video display are described. In one aspect, a method comprises reducing a phase difference between a first image and a second image in a portion of a frame time of the 3-dimensional video display. The method also comprises redistributing respective bit sequences of at least portions of the first image and the second image by respective amounts arranged to effect the reduction of the phase difference between the first image and the second image. The method also comprises displaying the redistributed respective bit sequences of the portions of the first image and the second image during the frame time of the 3-dimensional video display.

  • Publication number: 20120091866
    Abstract: Disclosed herein are embodiments of a speaker mounting assembly. In one such embodiment, the speaker mounting assembly comprises a speaker housing having a housing support surface, a speaker mounting bracket having a base surface, a projection extending from one of the speaker housing and the speaker mounting bracket and a mounting structure formed on the other of the speaker housing and the speaker mounting bracket. The mounting structure is configured to receive the projection such that the housing support surface contacts the base surface when the projection is received in the mounting structure. The mounting structure has an anti-rotation structure configured to prevent rotation of the speaker housing with respect to the speaker mounting bracket.

  • Patent number: 8078533
    Abstract: Financial transactions may be monitored for reporting requirements and regulatory compliance. A system provides for receipt of remittances, recognition of payment documents, storage of transaction information, and compliance verification by matching one or more cash equivalent transactions (CETs) made by an individual to determine if the aggregate of the transactions should be reported to meet compliance regulations. Images of the documents may be reviewed by an analyst to determine an account number and/or routing number associated with imaged document. If the information associated with the document reviewed has not been previously reviewed, it may be placed on a list of documents associated with CET transactions such that the document may be determined to be a CET in subsequent encounters with the document without human intervention.

  • Publication number: 20110228270
    Abstract: The invention is a combination of two prior arts (one being a tower elevator system and the other an open-path monitoring system) in order to perform automated “full wall” monitoring of an emission source. The system will allow an open-path detection system to take near real-time readings of the compounds present in the full area between the towers (both rectangular and triangular areas as shown in FIG. 1) by allowing either the retroreflector, or both the retroreflector and an open-path monitoring device to traverse the height of the towers. Sampled air is continuously monitored as the instrument traverses the tower. This is essentially a method for obtaining the impact of an emission source on the environment by acquiring a virtual “wall” of sampled air through automated and synchronized vertical movement and operation (both upstream and downstream of the source) of an open path detection method.

  • Patent number: 7936876
    Abstract: In accordance with the teachings the present invention, a system and method for transporting video data through a dual-link HD-SDI connection is provided. In a particular embodiment of the present invention, the method includes coupling a digital video projector and a playback server with a dual-link HD-SDI connection, the dual-link HD-SDI connection having four 10-bit subchannels; dividing 12-bit, 4:4:4, RGB video data into four 9-bit sections; mapping each 9-bit section of video data into nine least significant bits of a respective one of the four 10-bit subchannels; setting a most significant bit of each 10-bit subchannel to be a compliment of a next most significant bit of the 10-bit subchannel; and transporting the sections of video data from the playback server to the digital video projector through the dual-link HD-SDI connection.

  • Publication number: 20100312106
    Abstract: In some illustrative embodiments, an incoming signal from a transducer in an ultrasound imaging beam-former apparatus is applied to an in-phase sample-and-hold and a quadrature sample-and-hold. The quadrature sample-and-hold may be clocked a quarter period behind the in-phase sample-and-hold. The output of the sample-and-holds are applied to in-phase and quadrature analog-to-digital converters. A magnitude calculator receives the in-phase and quadrature digital values, and outputs a magnitude. A phase calculator receives the in-phase and quadrature digital values, and outputs a phase. An apodizer applies a difference between an amplitude of the outgoing signal and the magnitude and applies a first illumination to a image point in substantial proportion to the difference, and a phase rotator applies a second illumination to the image point in substantial proportion to the phase.

  • Patent number: 7832343
    Abstract: A pyrolyzer has a heated inner housing that includes first and second conveyors. Preferred conveyors have independent or at least potentially independent flows of material to be pyrolyzed. All suitable conveyors are contemplated, including especially screw conveyors, or combination of screw and paddle conveyors. Both first and second conveyors can be disposed within a common lumen, with a partial divider between them. An alternative divider is also contemplated that more or less divides the inner housing into two lumens. Thus, the lumens can be entirely distinct, or can have cross-flow of gases and/or material being pyrolyzed. Heat transfer fins can be advantageously attached, extend from, or be otherwise coupled to the inner housing to assist in transfer of heat into the lumen(s) of the inner housing.

  • Publication number: 20090293306
    Abstract: A mat (12) of impervious material for incorporation in an article, such as an article of footwear, for enabling airflow has a plurality of passageways (14) extending in a plane of the mat (12). At least one of the passageways of the plurality (14) is interconnected with at least one further passageway which extends substantially transversely to the plane of the mat (12). Air in passageways of the plurality can therefore flow to the further passageway(s) and air in the further passageway(s) can flow to passageways of the plurality. Air can therefor flow within the mat in two substantially transverse directions. Such a mat can be incorporated into an article to enable air flow into and out of the article.
