Method and system for prioritizing performance interventions

A member of a workforce of a contact center, such as an agent of a call center, can receive performance interventions, such as training, information, tips, or other items intended to enhance workplace performance. The performance interventions can be organized, sequenced, ranked, or prioritized in a lineup, an ordered list, or a queue, that specifies the sequence that the workforce member should receive the performance interventions. The agent might select a training course at the top of the list, for example. Two criteria, parameters, or values can characterize some aspect of each performance intervention. One criterion might characterize time sensitivity, while the other criterion might characterize importance, for example. Processing the two parameters can determine the sequence of performance intervention delivery.

Tooth movement system and method

A patient's dentition is analysed to determine an orthodontic treatment plan by simulating an intervention in advance. 3D imaging techniques and computer technology are used to simulate and predict tooth movement as a function of the chosen treatment, i.e. a specific orthodontic appliance. In this way treatment options can be compared and the most optimal (shortest treatment time, lowest forces . . . ) treatment for each individual patient can be selected. Sub-steps of the tooth movement are not predefined but computed based on a simulation of orthodontic elements and wire as they would be used in the orthodontic treatment of the patient. This means that the sub-steps are calculated based on the relationship between the applied loads and the tooth movement; only one of both parameters can be chosen freely. Thus, either the tooth load is specified and applied in order to calculate the resulting tooth movement or vice versa the tooth movement is specified and applied in order to calculate the tooth load that should be applied. Moreover, the current invention allows predicting the time at which brackets and / or archwire should be changed, and comparing different treatment options with respect to tooth loading and duration.

Method for forming a model of a geologic formation, constrained by dynamic and static data

Method for forming, by means of an inversion technique, a model of an underground zone, constrained by static data: data obtained by seismic exploration or measured in situ (logs), and by dynamic data: production measurement, well testing, etc. From an a priori selected meshed geologic model and from relations between parameters or physical quantities characteristic of the medium: acoustic impedance and cabsolute permeability for example, a simultaneous inversion of the two parameters is performed by minimizing a global cost function, which has the effect of considerably decreasing the number of possible solutions and of improving characterization of the underground zone. The method can be used notably for modelling hydrocarbon reservoirs, of zones likely to be used as gas, waste storage places, etc.

Device and Method for Generating a Coded Multi-Channel Signal and Device and Method for Decoding a Coded Multi-Channel Signal

In a multi-channel encoder generating several different parameter sets for reconstructing a multi-channel output signal using at least one transmission channel, the data stream is written such that the two parameter sets are decodable independently of each other. Thus, a multi-channel decoder is enabled to skip a parameter set which is marked as optional and / or has a higher version number when reading the data stream and still to perform a valid multi-channel reconstruction using a data set marked as mandatory or a data set having a sufficiently low version number. This achieves a flexible encoder / decoder concept suitable for future updates characterized by backward compatibility and reliability.

Thin hollow backlights with beneficial design characteristics

InactiveUS20100156953A1Reduce the total massLosses associated with the light sources are kept to minimal levelsCathode-ray tube indicatorsHollow light guidesBack reflectorLight guide
A backlight unit (10) has a hollow cavity (16) instead of employing a light guide. One or more light sources (24a-c), such as LEDs, are arranged to emit light into the cavity, which is formed by a front (12) and a back reflector (14). The backlight is typically of the edge-lit type. The backlight can have a large area, is thin and consists of fewer components than conventional devices. Its design permits light recycling. The unit emits light of a predefined polarisation and can be arranged to have desired horizontal / vertical viewing angle properties. Light is uniformly distributed within the guide and the light output (20b, 2Od) is substantially collimated. Such backlights occupy a specific region in a parameter space defined by two parameters: first, the ratio of the output emission area to the total source emission area should lie in the range 0.0001 to 0.1; and second, the ratio of the SEP to the height of the cavity (H) should be in the range 3 to 10, where the SEP is an average plan view source separation, a special measure of the average spacing of light sources in the plane of the unit. There is also a discussion on the required number of light sources N, their arrangement near the periphery of the cavity, as well as the shape and size of the output emission area. A required minimum brightness uniformity (VESA) value to be maintained, when a subset of Madjacent sources is switched off (where M is at least 0.1 N or M>2 or both), is also disclosed. The backlight can be used for a display or for general lighting purposes.

Method to control base station transmit power drift during soft handoffs

A UNMTS (universal mobile telecommunications system) based system comprises a common control point, a number of base stations, K, and a mobile terminal. During a soft handoff involving the K base stations and the mobile terminal, the common control point receives individual user channel transmit powers from each of the K base stations. In addition, the common control point receives two parameters from the mobile terminal—the identity of that base station involved in the soft handoff that has the strongest received signal at the mobile terminal and, on an average, a value representing how much stronger the received SNR was in comparison to the SNR target maintained by the mobile terminal. The common control point then decides on a downlink reference user channel transmit power for each of the base stations as a function of the individual user channel transmit powers reported by each base station involved in the soft handoff and the information provided from the mobile terminal.

Method and user interface tool for navigation through grid of scheduled items

Methods and software tools are described for allowing users to navigate through a time schedule quickly and easily. The time schedule interface facilitates a user viewing multiple time periods on an information schedule on a client device quickly without having to completely remake or redraw the entire interface. A user of a computer or similar device is presented with a time schedule interface. This schedule interface may resemble a schedule such as program guide or a train schedule. The schedule typically is composed of a grid or blocks of information defined by two parameters. One parameter is almost always time, while the other parameter depends on the type of schedule. The interface in this invention includes a moveable virtual slider. The slider rests on or is attached to a time scale axis. This time scale axis may be implemented as a horizontal or vertical bar and in addition may contain markings corresponding to time intervals much like a ruler. A user may select and control this slider along the time scale axis. The position of the slider along the time scale axis controls the time periods displayed in the schedule.
