A method for creating a playlist uses audio clips (i.e. a segment or portion of predetermined or selectable audio content from an audio data file) for audio data file recognition. Attributes of an audio clip may be selectable by the user such as length of playing time, audio file portion, an audio file category, data in an ID3 tag or the like. A user interface allows the user to add identifying data representative of an audio data file associated with an audio clip to the playlist. The method is applicable to all types of devices that play back audio content from a multitude of stored audio content. In particular, the method includes playback of an audio clip from each one of a set of audio data files during the playing of the audio clip. During playback of a particular audio clip, the user may add the selection to the playlist. Particularly, identifying data representative of an audio file associated with the currently playing audio clip is added to the playlist in response to user input. A user interface allows, for example, a single button or control to add content to a default, currently selected, or selectable playlist.

A method and system enables network intermediaries such as proxies to transcode multimedia data without violating end-to-end security guarantees. In one embodiment, a content provider decomposes a data stream into a plurality of components, each of which are independently encrypted. In a preferred embodiment, an intermediary or proxy performs transcoding of the components by prioritizing and dropping predetermined components, in accordance with unencrypted clear-text metadata associated with each component, without the need for decrypting the components. Clear-text metadata preferably provides a semantic understanding of the absolute or relative importance / priority of the components with respect to each other, thereby facilitating the transcoding process. The destination / client device can subsequently decrypt the components transmitted by the transcoding proxy and reassemble them into a representation of the original data content.

Methods and systems for accelerating data communication by reducing network latency particularly by data compression in which requested data is recursively compressed by an encoder and sent to the requester in codes which may or may not be understood by the requester. The requester can subsequently request data corresponding to unknown codes. The request-reply sequence is also recursive and continues until the requested data is present at the requester. To further accelerate communication, a persistently connected network is employed, together with a new socket layer capable of combining multiple messages from different machines, threads, and / or processes into single TCP / IP packets to be relayed along message hubs in the persistent network. These features are introduced singly and combined to create a new caching network. A new content distribution network can take advantage of these data communication improvements since requested content can be distributed in caches in a caching network.

Exemplary methods and apparatus for improving speed, scalability, robustness and dynamism of data transfers and workload distribution to remote computers are provided. Computing applications, such as Genomics, Proteomics, Seismic, Risk Management require a priori or on-demand transfer of sets of files or other data to remote computers prior to processing taking place. The fully distributed data transfer and data replication protocol of the present invention permits transfers which minimize processing requirements on master transfer nodes by spreading work across the network and automatically synchronizing the enabling and disabling of job dispatch functions with workload distribution mechanisms to enable / disable job dispatch activities resulting in higher scalability than current methods, more dynamism and allowing fault-tolerance by distribution of functionality. Data transfers occur asynchronously to job distribution allowing full utilization of remote system resources to receive data for job queues while processing jobs for previously transferred data. Processor utilization is further increased as file accesses are local to systems and bear no additional network latencies that reduce processing efficiency.

A fingerprint reading mechanism is utilized so as to determine which audience members are present during various stages of an audio, visual, or audiovisual program. The fingerprint reading mechanism is associated with a processing mechanism, an “enter” button, an “exit” button, a clock, memory, an output indicator, and a code receiver. As an audience member enters or exits the program performance area, the audience member places a hand, or portion thereof, in proximity to the fingerprint reading mechanism, and also presses the “enter” or “exit” button as appropriate. Optionally, the functionalities of the “enter” button and the fingerprint reading mechanism may be combined into a single automatically activated enter / fingerprint reading mechanism, and the functionalities of the “exit” button and the fingerprint reading mechanism may be combined into a single automatically activated exit / fingerprint reading mechanism. The fingerprint reading mechanism generates a fingerprint data record in response to a human hand, or portion thereof, held in proximity thereto. The processing mechanism compares the generated fingerprint data record with each of a plurality of stored fingerprint data records accessed from memory so as to permit retrieval of an audience member identifier corresponding to the generated fingerprint data record. An audience log entry associates the retrieved audience member identifier with a corresponding clock time parameter and a corresponding enter / exit parameter. In response to retrieving an audience member identifier from a generated set of fingerprint data, the processing mechanism creates and stores an audience log entry by loading the current value of the clock as the clock time parameter.

An SOI-based photonic bandgap (PBG) electro-optic device utilizes a patterned PBG structure to define a two-dimensional waveguide within an active waveguiding region of the SOI electro-optic device. The inclusion of the PBG columnar arrays within the SOI structure results in providing extremely tight lateral confinement of the optical mode within the waveguiding structure, thus significantly reducing the optical loss. By virtue of including the PBG structure, the associated electrical contacts may be placed in closer proximity to the active region without affecting the optical performance, thus increasing the switching speed of the electro-optic device. The overall device size, capacitance and resistance are also reduced as a consequence of using PBGs for lateral mode confinement.

The system generates an individual care plan for a patient base on the identified markers and the claims data containing clinical information relating to the patient.

Touch sensitivity is enabled using a touch system that comprises a panel configured to conduct signals, e.g. by TIR, along detection lines across a touch surface. A signal processor operates to generate data samples indicative of transmitted signal energy on parallel detection lines at a number of different angles across the touch surface; process the data samples for generation of interpolated Fourier coefficients at grid points in a regular grid in a Fourier domain; and operate a two-dimensional inverse Fourier transform on the interpolated Fourier coefficients so as to generate an interaction pattern for the touch surface. The interpolated Fourier coefficients are generated sequentially for individual groups of grid points. Each individual group comprises grid points that have equal distance to an origin in the regular grid, e.g. grid points that are mapped onto each other by one or ore lines of symmetry in the regular grid. The group-based processing may improve processing speed and / or reduce the need for data storage.

A method and system for transforming a video image from a High Dynamic Range (HDR) image on an array of pixels to a Low Dynamic Range (LDR) image. An old luminance generated from a color space of the HDR image is scaled and segmented into stripes. Each stripe has at least one row of the array. A target zone surrounding a current pixel in each stripe is determined from a search strategy selected from a linear search strategy and a zone history-based search strategy. A convolution of the scaled luminance at a current pixel of each stripe is computed using a kernel specific to the target zone. The convolution is used to convert the stripes to tone-mapped luminance stripes which are collected to form a tone mapped luminance pixel array that is transformed to the color space to form the LDR image. The LDR image is stored and / or displayed.

Hashing functions have many practical applications in data storage and retrieval. Perfect hashing functions are extremely difficult to find, especially if the data set is large and without large-scale structure. There are great rewards for finding good hashing functions, considering the savings in computational time such functions provide, and much effort has been expended in this search. This in mind, we present a strong competitive evolutionary method to locate efficient hashing functions for specific data sets by sampling and evolving from the set of polynomials over the ring of integers mod n. We find favorable results that seem to indicate the power and usefulness of evolutionary methods in this search. Polynomials thus generated are found to have consistently better collision frequencies than other hashing methods. This results in a reduction in average number of array probes per data element hashed by a factor of two. Presented herein is an evolutionary algorithm to locate efficient hashing functions for specific data sets. Polynomials are used to investigate and evaluate various evolutionary strategies. Populations of random polynomials are generated, and then selection and mutation serve to eliminate unfit polynomials. The results are favorable and indicate the power and usefulness of evolutionary methods in hashing. The average number of collisions using the algorithm presented herein is about one-half of the number of collisions using other hashing methods. Efficient methods of data storage and retrieval are essential to today's information economy. Despite the cur-rent obstacles to creating efficient hashing functions, hashing is widely used due to its efficient data access. This study investigates the feasibility of overcoming such obstacles through the application of Darwin's ideas by modeling the basic principles of biological evolution in a computer. Polynomials over Zn are the evolutionary units and it is believed that competition and selection based on performance would locate polynomials that make efficient hashing functions.
