Abstract:
Methods and apparatus for measuring a phase fraction of a flow stream are disclosed. An infrared phase fraction meter includes a light source for emitting into a flow stream infrared radiation that includes first and second wavelength bands. The first wavelength band substantially transmits through first and second phases of the flow stream and is substantially absorbed by a third phase. In contrast, the second wavelength band is substantially absorbed by the second phase relative to the first and third phases. One or more detectors simultaneously detect attenuation of the first and second wavelength bands upon the infrared radiation passing through at least a portion of the flow stream, and a phase fraction of the second phase is determined based on the attenuation. As an example, the first, second and third phases are gas, water and oil, respectively, produced from a well.
Abstract:
A method of controlling acceptance of a call by a network node in a communication network having a required quality of service includes the steps of determining an infimum of a function of the probability of the node being overloaded if the call if accepted and determining from that infimum the effective bandwidth of the calls to the node if that call should be accepted and determining a corresponding quality of service. The corresponding quality of service is then compared with a quality of service that is required for satisfactory operation of the network. If the quality if maintained or exceeded then the call is accepted for the node.
Abstract:
A method and apparatus for utilizing a digital computer to print characters of multiple fonts, both textually and graphically, on a single printer from within a single document [is disclosed]. Existing computer programs provide the capability of printing pre-defined textual characters or graphical characters separately, but not in an integrated manner as is disclosed. Thus, the invention enables printing of a variety of mixed characters, such as international alphabetic characters and complex mathematical characters, within a single document.
Abstract:
The present invention provides a method of registering image data for a series of images acquired over a period of time. The images may be acquired from a medical imaging device, such as an MRI scanner. The method allows image-by-image registration to a partially compressed dataset in which motion artefacts are suppressed in a series of target images generated to resemble the original dynamic data. The registration process is refined with each iteration of the process. The method uses Principal Component Analysis which allows accurate registration to be performed without the need to make any assumptions about pharmacokinetic model parameters, which not only avoids the problems of accurate model-fitting but permits the use of much larger target areas of the dataset.
Abstract:
A method and apparatus for controlling the ratio of ambient air to recirculated gases in an internal combustion engine, wherein an gas injector includes a intake air conduit defining a ambient air flow path, an actuator connected to the intake air conduit, a recirculated gas conduit operatively coupled and disposed within the intake air conduit defining a recirculated gas flow path and a valve apparatus operatively coupled to the intake air conduit and recirculated gas conduit. The valve apparatus includes; a shaft, a throttle valve coupled to the shaft and in fluid communication with the ambient air flow and a recirculated gas valve coupled to the shaft in fluid communication with the recirculated gas flow. The shaft rotates one of the throttle valve and the recirculated gas valve independent of the rotation of the other one of throttle valve and said recirculated gas valve.
Abstract:
An optical transmission apparatus for transmission of optical signals at an optical wavelength of about 1550 nanometers. The optical transmission apparatus includes a single mode optical fiber link formed of optical fiber having substantially zero dispersion at an optical wavelength of about 1300 nanometers and a dispersion of about 17 picoseconds per nanometer-kilometer at an optical wavelength of about 1500 nanometers. Further, at least one dispersion compensating chirped optical fiber grating is coupled to the optical fiber link, the aggregate dispersion of the at least one dispersion compensating chirped optical fiber grating substantially compensating for the dispersion of the optical fiber link. Further, the at least one dispersion compensating chirped optical fiber grating is coupled at respective positions substantially symmetrically disposed about the longitudinal center of the optical fiber link.
Abstract:
A method of reprinting content on a print medium using a mobile telecommunications device, comprising the steps of: determining a first print media identifier, from a first print medium provided with content, using a sensor module of the mobile telecommunications device, the first print medium having been inserted into a media feed path of the mobile telecommunications device; retrieving a copy of the content, previously stored in a database, using the print media identifier; and, printing the copy of the content on a second print medium using a printer module of the mobile telecommunications device.
Abstract:
A method of printing content on a print medium and charging using a mobile telecommunications device, comprising the steps of: identifying the content on the mobile telecommunications device; printing, using a printer module of the mobile telecommunications device, the content on the print medium; and transmitting, using the mobile telecommunications device, billing information to a billing server.
Abstract:
A mobile device including: a printhead disposed in a print path along which a print medium travels while being printed; and a sensor in the print path to sense when a print medium has been inserted therein; the mobile device being configured to: sense, using the sensor, that a print medium has been inserted; without further user intervention, commence printing onto the print medium.
Abstract:
A method and apparatus for alerting a user of the status of an appliance includes a controller that is coupled to a telephone network and a keypad to permit the entry of a numeric sequence and to communicate the numeric sequence to the controller. The keypad is coupled to the control circuit of the appliance to determine whether the appliance has commenced a requested task, to determine if the requested task has been completed, and to provide the numeric sequence to the controller in response to determination that the requested task has been completed. The controller initiates a call over the telephone network based upon the numeric sequence to provide notification of the completion of the requested tasks by the appliance.
