A quality of service profile for a mobile communication subscriber unit is determined and includes one or more mobile-specific desired quality of service parameters. Actual values for the service parameter(s) is(are) determined and fed back to a link quality controller to determine whether they are in an acceptable range or relationship with corresponding actual quality of service parameter values. A modulation and/or coding scheme for transmitting the information over the radio link is selected or adjusted based on whether the desired and actual quality of service parameters are in an acceptable range or acceptable relationship. A combined “desired” quality of service parameter using the first and second quality of service parameters (or more if desired) may be determined. A combined “actual” quality of service parameter using first and second actual quality service parameter values is determined. Those combined desired and actual quality of service parameters are compared to determine whether they are in an acceptable range or relationship. The modulation or coding scheme (or both) is (are) selected or adjusted based thereon.

A method and system is provided for identifying in-range sensor faults in a gas turbine engine, by observing the tracked component qualities in an embedded model and recognizing anomalous patterns of quality changes corresponding to sensor errors. An embedded model of the engine is employed to estimate sensed parameters such as rotor speeds, temperatures and pressures, as well as other parameters that are computed based on input parameters. Each major rotating component of the engine, including the fan, compressor, combustor, turbines, ducts and nozzle is individually modeled. Sensor failures are detected by identifying anomalous patterns in component quality parameters. A library of anomalous patterns is provided for comparing quality parameters generated by a tracking filter with the library of anomalous patterns. If a pattern is matched, a sensor may be eliminated from the tracking filter and the estimated model parameter used to avoid corrupting the model quality parameters.

The present invention relates to a process and a device in a radio communication system for observing the quality of channels that are to used in uplink and channels that are to be used in downlink. A quality parameter, for example the interference, is measured (301) for both uplink channels and downlink channels from a measurement receiver comprised in each base station. The measured interference is an approximation to the real downlink interference. The approximation has best correspondence with the real interference situation when the base station and the mobile stations are placed at similar height, for instance in micro- and pico cells. The measurement values can be used for adaptive allocation of frequencies or channels, or for giving statistical information about the radio communication system.

An apparatus, system, and method for the measurement, aggregation and analysis of data collected using non-contact or minimally-contacting sensors provides quality of life parameters for individual subjects, particularly in the context of a controlled trial of interventions on human subjects (e.g., a clinical trial of a drug, or an evaluation of a consumer item such as a fragrance). In particular, non-contact or minimal-contact measurement of quality-of-life parameters such as sleep, stress, relaxation, drowsiness, temperature and emotional state of humans may be evaluated, together with automated sampling, storage, and transmission to a remote data analysis center. One component of the system is that the objective data is measured with as little disruption as possible to the normal behavior of the subject. The system can also support behavioral and pharmaceutical interventions aimed at improving quality of life.

A method, program product and system for conducting a ray tracing operation where the rendering compute requirement is reduced or otherwise adjusted in response to a changing vantage point. Aspects may update or reuse an acceleration data structure between frames in response to the changing vantage point. Tree and image construction quality may be adjusted in response to rapid changes in the camera perspective. Alternatively or additionally, tree building cycles may be skipped. All or some of the tree structure may be built in intervals, e.g., after a preset number of frames. More geometric image data may be added per leaf node in the tree in response to an increase in the rate of change. The quality of the rendering algorithm may additionally be reduced. A ray tracing algorithm may decrease the depth of recursion, and generate fewer cast and secondary rays. The ray tracer may further reduce the quality of soft shadows, resolution and global illumination samples, among other quality parameters. Alternatively, tree rebuilding may be skipped entirely in response to a high camera rate of change. Associated processes may create blur between frames to simulate motion blur.
