A speaker recognition system for authenticating a mobile device user includes an enrollment and learning software module, a voice biometric authentication software module, and a secure software application. Upon request by a user of the mobile device, the enrollment and learning software module displays text prompts to the user, receives speech utterances from the user, and produces a voice biometric print. The enrollment and training software module determines when a voice biometric print has met at least a quality threshold before storing it on the mobile device. The secure software application prompts a user requiring authentication to repeat an utterance based at least on an attribute of a selected voice biometric print, receives a corresponding utterance, requests the voice biometric authentication software module to verify the identity of the second user using the utterance, and, if the user is authenticated, imports the voice biometric print.

Methods, systems and processor-readable media for extracting and classifying location information utilizing social media messages and / or data thereof. The social media messages can be sampled from a social media database and the messages filtered based on a heuristic rule. A geolocation entity from the unstructured social media messages can be extracted utilizing a geolocation entity extracting module. The messages with the geoentities can be uploaded onto a crowd sourcing platform to manually annotate the messages with a label. A text classification model can be built and learned from the label utilizing a machine learning algorithm and the messages can be classified by a location classifier in order to extract the user location. The user location can then be transformed into a geocode so that a spatial search can be enabled and the distance between the locations can be easily calculated.

The present invention includes systems and methods for retrieving information via a flexible and consistent targeted search model that employs interactive multi-prefix, multi-tier and dynamic menu information retrieval techniques (including predictive text techniques to facilitate the generation of targeted ads) that provide context-specific functionality tailored to particular information channels, as well as to records within or across such channels, and other known state information. Users are presented with a consistent search interface among multiple tiers across and within a large domain of information sources, and need not learn different or special search syntax. A thin-client server-controlled architecture enables users of resource-constrained mobile communications devices to locate targeted information more quickly by entering fewer keystrokes and performing fewer query iterations and web page refreshes, which in turn reduces required network bandwidth. Applications are built by leveraging existing collaborative cloud services that enable the maintenance and sharing of user content.

A disk drive is disclosed that utilizes multi-tiered solid state memory for caching data received from a host. Data can be stored in a memory tier that can provide the required performance at a low cost.

As another example, single-level cell (SLC) memory can be used to store data that is frequently written. Improved performance, reduced costs, and improved power consumption can thereby be attained.

In a massed region of each of a plurality of transfer areas of a mask a plurality of light transmission patterns are formed by opening a half-tone film. A phase shifter is disposed in each of the light transmission patterns so that a 180° phase inversion occurs between the lights that transmit through adjacent light transmission patterns. In a sparse region of the plurality of transfer areas a solitary light transmission pattern is formed by opening the half-tone film. Both shape and size are the same among the light transmission patterns, which are disposed symmetrically in both the massed and sparse regions about the center between the transfer areas. The phase shifters in the massed regions are disposed so that the phase of each phase shifter in one of the transfer areas comes to be opposed to that of its counterpart in the other transfer area. In the exposure process, those transfer areas are overlaid one upon another in the same chip region.

The stream data node may also be part of a query execution data structure, where it delivers its data when requested by another node in the query execution data structure.

Fourier domain a / LCI (faLCI) system and method which enables in vivo data acquisition at rapid rates using a single scan. Angle-resolved and depth-resolved spectra information is obtained with one scan. The reference arm can remain fixed with respect to the sample due to only one scan required. A reference signal and a reflected sample signal are cross-correlated and dispersed at a multitude of reflected angles off of the sample, thereby representing reflections from a multitude of points on the sample at the same time in parallel. Information about all depths of the sample at each of the multitude of different points on the sample can be obtained with one scan on the order of approximately 40 milliseconds. From the spatial, cross-correlated reference signal, structural (size) information can also be obtained using techniques that allow size information of scatterers to be obtained from angle-resolved data.

A system for developing and implementing empirically derived algorithms to generate decision rules to determine participant noncompliance and fraud with research protocols in clinical trials allows for the identification of complex patterns of variables that detect or predict participant noncompliance and fraud with research protocol, including performance and enrollment goals, in the clinical trial. The data may be used to overall predict the performance of any participant in a clinical trial, allowing selection of participants that tend to produce useful, high-quality results. The present invention can also be used to monitor participant compliance with the research protocol and goals to determine preferred actions to be performed. Optionally, the invention may provide a spectrum of noncompliance, from minor noncompliance needing only corrective feedback, to significant noncompliance requiring participant removal from the clinical trial or from future clinical trials. The algorithms and decision rules can also be domain-specific, such as detecting non-compliance or fraud among subjects in a cardiovascular drug trial, or demographically specific, such as taking into account gender, age or location, which provides for algorithms and decision rules to be optimized for the specific sample of participants being studied.

The present invention presents a non-volatile memory system that adapts its performance to one or more system related situation. If a situation occurs where the memory will require more than the allotted time for completing an operation, the memory can switch from its normal operating mode to a high performance mode in order to complete the operation quickly enough. Conversely, if a situation arises where reliability could be an issue (such as partial page programming), the controller could switch to a high reliability mode. In either case, once the trigging system situation has returned to normal, the memory reverts to the normal operation. The detection of such situations can be used both for programming and data relocation operations. An exemplary embodiment is based on firmware programmable performance.
