摘要:
Described techniques and tools help model checking scale to large programs while reducing missed errors. In particular, described techniques and tools help reduce the state space of concurrent programs without depending on cycle detection and without scheduling execution of postponed threads at all cycles. For example, described techniques and tools use a type of partial-order reduction called transaction-based reduction to reduce program state space. Analysis is performed at commit points to determine whether to schedule delayed threads.

The invention includes a necktie fastener system capable of restraining the bottom portion of the necktie close to the shirt of a wearer, and thereby controlling the entire necktie so that it won't fly in the wind, or while leaning over a table. The invention is for use when wearing a shirt having buttons located near the center of the front of the shirt. There is an H shape which is attached to the back of the apron of the necktie by simply hot ironing it. The H shape is relatively flexible allowing easy formation of the various necktie knots. Once the necktie has been tied and adjusted, the wearer inserts the a elongated placket under the horizontal bar and attaches the placket to two adjacent shirt buttons. The resulting combination slidably secures the end of the necktie nearest the bottom of the tie to stay near the shirt of the wearer. This gives control of the entire length of the tie from flying away in the wind or falling down when reaching over a table.

Methods and systems for combining multiple video streams are provided. Video feeds are received from multiple optical sensors, and homography information and/or corner metadata is calculated for each frame from each video stream. This data is used to mosaic the separate frames into a single video frame. Local translation of each image may also be used to synchronize the video frames. The optical sensors can be provided by an airborne platform, such as a manned or unmanned surveillance vehicle. Image data can be requested from a ground operator, and transmitted from the airborne platform to the user in real time or at a later time. Various data arrangements may be used by an aggregation system to serialize and/or multiplex image data received from multiple sensor modules. Fixed-size record arrangement and variable-size record arrangement systems are provided.

An integrated receiver supports adaptive receive equalization. An incoming bit stream is sampled using edge and data clock signals derived from a reference clock signal. A phase detector determines whether the edge and data clock signals are in phase with the incoming data, while some clock recovery circuitry adjusts the edge and data clock signals as required to match their phases to the incoming data. The receiver employs the edge and data samples used to recover the edge and data clock signals to note the locations of zero crossings for one or more selected data patterns. The pattern or patterns may be selected from among those apt to produce the greatest timing error. Equalization settings may then be adjusted to align the zero crossings of the selected data patterns with the recovered edge clock signal.

A method and system for automated review and analysis of appraisal reports, including receiving and identifying an appraisal report. After identifying the appraisal report, relevant data and/or information contained therein is identified and extracted. The extracted data and/or information are then normalized for subsequent evaluation. Thereafter, the normalized data and/or information is evaluated to determine, for example, whether the appraisal report complies with generally accepted appraisal practices and whether the appraised property represents a low, moderate, high, or very high risk. The method and system also generates an output relating to the appraisal report evaluation.

A surveillance system interface includes a displayed wide-angle image and a contemporaneously displayed narrower-angle image. The interface permits a user to select a view within the wide-angle image to indicate a region of interest. The narrower-angle image may then be made to correspond to the indicated region of interest.

An apparatus to separate solids from drilling slurry, having an inlet positioned over an outlet of a concentration tank to displace water that would otherwise enter the down-stream centrifuges. Baffles are provided to direct solids to the outlet and minimize the time that solids spend in the concentration tank. Fluids having solids removed therefrom are removed from the apparatus at a location remote from the outlet.

A fluid coupling device employs a male spherical member with a fluid receiving bore and a female housing. The spherical member abuts two axially spaced Teflon ring seats between the member and the housing in the housing chamber. The ring seats reduce friction between the member and the housing, and axially retain the member in the housing with no metal to metal contact. A first O-ring provides fluid sealing between the spherical member and housing inner wall in the chamber. A hose receiving nipple member with a fluid receiving bore has a threaded concave end with a peripheral region that engages the first O-ring to hold the O-ring against the spherical member, one of the ring seats and housing chamber wall to seal the interface between the spherical member and housing. The nipple member has a flange which abuts the housing to limit squeezing action on the O-ring to ensure sufficient contact of the O-ring and mating surfaces to obtain a good seal without creating excessive friction loads. A second O-ring seals the interface between the flange and housing.

The present invention relates to a communication system, protocol and method designed to facilitate information transfer including user and control information from CBR (Continuous Bit Rate) and/or non-CBR signal sources. Such a system, for example, is a CSS (Customer Switching System), a LAN network, a Key System, LAN hub, PABX or PBX. A number of aspects are disclosed in this specification. These include: A) a key system and/or LAN which utilizes ATM technology for the trafficking of CBR, non-CBR, or a combination thereof, B) a round robin feature which facilitates the operation of i. above, C) a cell format which facilitates the operation of i. above, D) an open and closed system architecture for i. above, E) and ATM-TP which serves as an interface for CBR to the architecture and an ATM-HP which serves as an interface for non-CBR to the architecture, F) partial cell filling for system efficiency and/or echo control, G) a staggering feature to facilitate system efficiency, H) a channel aggregation feature to reduce the requirement for external adaptor equipment, I) a by-pass feature to enhance system reliability and serviceability. An example of CBR is voice, video and "non-bursty" data. An example of non-CBR or "bursty" data is LAN data.
