摘要： A mobile wireless device, such as a mobile wireless phone, is adapted based on a user's current abstracted contextual situation, where the context of a user is determined using devices enabled with near-field communication technology. Dynamic information of a user of a mobile device, such as the identity of his or her current environment, is determined using near-field communication, such as radio-frequency identification (RFID) tags. Static information regarding the user is also determined, where such static information can include the user's preferences regarding how the mobile device should adapt to certain environments. An abstracted contextual situation of the user is synthesized based on this dynamic and static information. One or more adaptation directives for the mobile device of the user are determined based on the user's abstracted contextual situation. The adaptation directives are implemented for the mobile device, without user interaction, or by instructing the user to appropriately configure the mobile device.

摘要： Techniques for assessing pronunciation abilities of a user are provided. The techniques include recording a sentence spoken by a user, performing a classification of the spoken sentence, wherein the classification is performed with respect to at least one N-ordered class, and wherein the spoken sentence is represented by a set of at least one acoustic feature extracted from the spoken sentence, and determining a score based on the classification, wherein the score is used to determine an optimal set of at least one question to assess pronunciation ability of the user without human intervention.

摘要： The present invention provides a hybrid call handling method and system. The method comprises navigating a plurality of received calls from a plurality of callers. The method further comprises monitoring a call health status for each of the plurality of the calls being navigated for entire call duration and notifying a bad call health status of the monitored call to a human agent for employing at least one rectification action. The call health status is determined by monitoring and measuring one or more call parameters. The invention provides for a system for call handling and navigation by an automated system with a human agent assisting the automated system for rectification of calls with bad call health status. Once the call with a bad health is transferred to the human agent, he assists the automated system either by directly communicating with the caller or by communicating using a machine interface.

摘要： This disclosure concerns a vertical lasing semiconductor optical amplifier (VLSOA) having a quantum dot active region. In one example, a VLSOA includes a quantum dot active region comprising a semiconductor gain medium. The semiconductor gain medium defines at least a portion of an amplifying path. The VLSOA also includes a laser cavity within which a portion of the semiconductor gain medium is disposed. The laser cavity has a gain characteristic, with respect to an optical signal traversing the amplifying path, that is responsive to a pump input to the laser cavity.

摘要： Systems and methods for stripping an optical mode from a semiconductor laser. A waveguide layer is included in the semiconductor laser and is typically arranged beneath the active region. The waveguide layer is configured to match the phase of the second order mode. The waveguide layer does not substantially match the primary optical mode of the laser. By matching the phase of the second order mode, the confinement of the second order mode is reduced and the second order mode strongly couples with the waveguide layer. The optical confinement of the primary mode is not substantially reduced. The side-mode suppression ratio is thereby improved by stripping the second order mode from the active region.

摘要： A method of classifying samples to one of a number of predetermined classes involves using a number of class models or classifiers to form order statistic for each classifier. A linear combination of the order statistic (L-statistic) is calculated to determine the confidence of that particular classifier, both in general and for that particular sample. Relative weights are then derived from these confidences, and used to calculate a weighted summation across all classifiers for each class of the likelihoods that a sample belongs to that class. The sample is classified in the class which has the associated weighted summation which is greatest in value.

摘要： A language model is constructed for mixed language expressions that have words from more than one natural language. Word equivalence probabilities for pairs of words among the languages are generated and stored. Word equivalence probabilities are used as required to generate a monolingual word history. The monolingual history is used by a monolingual language model to generate a next-word hypothesis. The word equivalence probabilities are also used to compute the next word probabilities in the foreign language.
