摘要:
A computer system for extrapolating from relatively small amounts of information provided by a consumer to generate a wide range of travel options that are still associated with the information provided by the consumer. For example, the system includes processes for generating or finding travel packages with exactly matching travel dates and destinations supplied by the consumer. In addition, the system includes processes for varying the dates of travel by several days, or proximate weekends, and the destination of travel with nearby or regional destinations, so as to generate or find additional travel options. Further, the system can be configured to extract a theme of the consumer requested information and to use this theme to construct or find travel packages with similar or matching themes.

A method of testing a digital mobile phone network such as a GPRS or 3G network comprises either using real traffic or creating test traffic using test mobile phone coupled to a computer, and using the computer to measure a parameter associated with the network's response to the traffic. The measurements made by the computer are themselves sent as traffic to create one or more data streams within the mobile phone network comprising the traffic, measurements relating to the traffic, and signalling relating to the traffic, whereby this data stream or these streams can be captured at interface points within the network and analysed to investigate the functioning of the network dynamically as the network is exercised with the traffic. Software and test equipment for performing the method are also described.

A four-stroke cycle reciprocating internal combustion engine includes a piston mounted for reciprocal movement within a power cylinder and primary and secondary intake valves. The primary valve has a fixed event, in terms of both duration and lift, and the secondary valve has variable duration and lift. Although the timing of the primary and secondary valve events may be retarded from a standard timing value, both valves close at the same time regardless of the presence of timing retard. The dual event strategy, combined with camshaft timing retard for part load conditions, produces excellent charge motion by staggering the respective lifted flow areas of the primary and secondary valve events and by delaying the secondary valve opening.

A method, system, apparatus and device for the monitoring, diagnosis and evaluation of the state of a dynamic system is disclosed. This method and system provides the processing means for receiving sensed and/or simulated data, converting such data into a displayable object format and displaying such objects in a manner such that the interrelationships between the respective variables can be correlated and identified by a user. This invention provides for the rapid cognitive grasp of the overall state of a critical function with respect to a dynamic system. The system provides for displayed objects, which change in real-time to show the changes of the functions of the system. It is a highly flexible system which works with a wide variety of applications, including biological systems, environmental systems, engineering systems, economic systems, mechanical systems, chemical systems and the like. The device of this invention is adapted specifically to providing objects within a frame associated with other objects in a reference grid to provide a graphical representation of cardiovascular function.

The disclosed roller switch has a roller, a flag arm, and a photoelectric detector. The roller is connected to the flag arm and vertical movement of the roller causes the flag arm to move. The movement of the flag arm causes the photoelectric detector to send a signal. The signal may be used to measure the length of a material passing under the roller. The inventive roller switch has a pair of flag arms, and the roller is mounted on a shaft extending between the pair of flag arms. By providing a pair of flag arms connected by the roller, the roller switch is more robust and durable. The roller switch is also capable of pivoting across a conveyor belt.

An automotive internal engine 8 is provided which includes an engine controller 70 cognizant of a desired deceleration condition for a vehicle and a combustion chamber 12 with a reciprocating piston 15 mounted therein. The piston has a top dead center and a bottom dead center position. A cam driven exhaust valve 14 is provided which can be selectively disabled to a closed position to deactivate the combustion chamber 12 in response to a signal given by the engine controller 70. A variable phase cam driven intake poppet valve 16 responsive to a signal given by the engine controller 70 is provided to selectively set the opening and closing operation of the intake poppet valve 16 to be generally symmetrical about one of the center positions during the first combustion chamber 12 deactivation during vehicle deceleration.

A core crush resistant prepreg for use in making a fiber reinforced composite panel structure is provided. The prepreg comprises a woven fabric consisting essentially of carbon fiber tow strands impregnated with a hardenable polymeric resin composition. Typically the fabric has an areal weight of from about 180 to about 205 grams per square meter. The prepreg has an average fiber tow aspect ratio of less than about 15.4, a prepreg thickness of at least about 0.245 mm, and a prepreg openness of at least about 1.2 percent but less than about 6.0 percent. Preferably, the resin composition is predominantly viscous in nature and has a tan &dgr; value of between 0.9 and 2.0 at an elevated temperature between 70° C. and 140° C., and an average epoxy functionality of greater than 2.0. A method for evaluating core crush resistance properties of a prepreg is also provided. The method includes determining a fiber tow average aspect ratio of the prepreg, determining a prepreg thickness, and comparing said average fiber tow aspect ratio and prepreg thickness to a set of predetermined values.
摘要:
An internal combustion engine valve control system for improving automotive cold-starts. A “negative” valve-overlap (NVO) time period is created during a first part of each piston's intake stroke wherein, with the intake and exhaust valves closed, a high vacuum is produced in its associated cylinder. As the intake valve starts to open at the end of the period an initial small low-lift valve gap creates a high-pressure differential across the gap increasing the velocity of the air/fuel charge being injected through the gap. The added velocity elevates turbulent mixing intensity in the cylinder enhancing atomization and vaporization of the charge, improving distribution in the combustion chamber for charge stability. This allows additional spark retard and a leaner air/fuel ratio, achieving rapid catalyst warm-up, while promoting converter efficiency and reducing exhaust-gas emissions.

The present invention provides a position-sensing system which employs sensors incorporating magnetoresistive materials. The position of a magnetic information input member is determined through the resistance change of the magnetoresistive sensor in response to the magnetic field from the magnetic information input member. Exemplary magnetoresistive materials are lanthanum manganites having high magnetoresistive ratios. Two-dimensional position sensing systems for graphics tablets are also described.
