摘要:
The present invention provides methods, compositions, and kits comprising snap-back primers used for forming 3′ hairpin structures, 5′ hairpin structures, and double hairpin structures. The hairpin structures may be used for detecting target sequences (e.g., such as small RNA target sequence), for detecting polymorphisms in target sequences (e.g., such as polymorphisms located near the 5′ or 3′ ends of the target sequence), or other nucleic acid characterization methods. In certain embodiments, the hairpin structures form invasive cleavage structures (e.g., in combination with a probe or upstream oligonucleotide) which may be cleaved by structure-specific enzymes in order to detect the presence or absence of a particular nucleotide or nucleotide sequence.

An observation system for observation calls to a call center includes an automatic call director (ACD) unit, an interactive voice response (IVR) unit, and a recorder unit. The ACD receives incoming calls to the call center and also queues and switches the calls to various lines of the call center. The IVR unit is connected to the ACD unit and interacts with a caller via an interactive computer program in which the caller enters a response to a prompt and the response causes the interactive program to provide the caller with information or another prompt. The recorder unit records calls to the call center from beginning to end, including prompts made by the IVR unit, callers responses to the prompts, and information provided by the IVR unit to the callers.

A system for forming a database indexed with content-based parameters, corresponding to recordings of contacts to a contact center, includes an analysis unit, a mining unit, and a correlation unit. The analysis unit performs automated-portion analysis techniques to ascertain predetermined events occurring in recordings of automated portions of the contacts to the contact center. The mining unit performs audio mining of recordings of agent portions of the contacts to the contact center. The correlation unit correlates an event occurring in an agent portion of the recordings with a corresponding one of a plurality of content-based parameters selected to be used as indices of the database, and makes an entry in the database based on the correlated event and the corresponding content-based parameter.

This invention discloses a small slot antenna incorporated within a flat circuit board and having a three dimension omni-directional radiation pattern. In one embodiment, the antenna is formed as an L shaped slot along two edges of the circuit board of a miniature radio transceiver. The antenna is ideally suited for use in applications where radio frequency inventory tags (operating in the high VHF to low UHF frequency ranges of 400 to 500 mHz) are associated with items for which a high level of inventory control is required. It is important that such tags be able to communicate with vertical and horizontal polarized signals with reasonable gain. This invention features a low cost for manufacture and has application in radio communications in general wherever there is a requirement for a small transceiver with an integrated, orientation insensitive antenna.

The present invention provides compositions and methods for the detection and characterization of mutations associated with cystic fibrosis. More particularly, the present invention provides compositions, methods and kits for using invasive cleavage structure assays (e.g. the INVADER assay) to screen nucleic acid samples, e.g., from patients, for the presence of any one of a collection of mutations in the CFTR gene associated with cystic fibrosis. The present invention also provides compositions, methods and kits for screening sets of CFTR alleles in a single reaction container.
摘要:
A system for analyzing an interactive voice response (IVR) system of a call processing center determines a complete sequence of events occurring within the IVR system. The IVR system being operable to automatically accept calls from callers and respond to input from the callers. The system models a call flow of the IVR system as a non-deterministic finite-state automaton. A recording of a plurality of calls to the call processing center is split, such that each of plural calls to the call center is in one audio file. For a plurality of calls, the system detects a complete sequence of DTMF and/or speech input to the IVR system, detects selected prompts issued by the IVR system, and inputs the detected sequence of DTMF and/or speech input as well as the detected prompts issued by the IVR system into the finite-state automaton to determine a call-event sequence for that call. The call-event sequence includes information regarding how that call left the IVR system.

Message delivery approaches are disclosed in which senders can define filters with associated actions for evaluation in relation to specified messages. After creating and storing filters with specified actions, senders dispatch messages to a processing system, which evaluates the filters against the messages. If a match occurs, the processing system performs the specified actions on the messages. In one embodiment, the processing system can send the same message multiple times to different receiving systems, and can modify the source IP address and outbound interface of the message for each receiving system. Further, the source IP address or interface may be modified by a filter in response to external events, such as a receiving system blocking another copy of the message. In this way, a single message processing system can appear as a large number of virtual message sending units, thereby increasing the chance that a particular message will arrive at its destination without blocking by message blocking or filtering technologies at the receiver. For bulk mailers, different filters can be associated with different communication campaigns.
摘要:
Systems and methods that, among other things, analyze and monitor the performance of a call center including performance of the interactive voice response (IVR) systems, call center agents, and other components of the call center. The systems and methods record characteristics of the call such as the audio data, and analyze that record to identify the events and the actions that take place during the call. These events and actions may be defined as complex customer/call center interactions, such as dropped calls, logic errors or other event. A call center administrator may also identify a set of metrics, such as the number of dropped calls that occur during a day or for each agent, the number of times a client was left on hold for more than two minutes, or other such metrics that may be monitored by the systems described herein. The data collected about these events and the resulting metrics may be stored in a database and provided to a call center administrator through a user interface that allows the administrator to browse through the collected metric and recorded call data and directly review relevant portions of a call that are of interest to the administrator.
摘要:
An apparatus and method for monitoring the performance of an interactive voice response (IVR) system used by an automated call processing center generates logs of call activity, determines routing information from the logs, notes predetermined significant activity in agent-caller dialog portions of calls routed to an agent in the logs, and determines at least one quantity correlated to a true intention of callers. A performance model of the IVR system is generated from the logs. The logs, the routing information, the quantity correlated to the true intention of the callers, and the performance model are analyzed to determine a performance value of the IVR system, which is used to monitor the IVR system.
