A location system is disclosed for commercial wireless telecommunication infrastructures. The system is an end-to-end solution having one or more location centers for outputting requested locations of commercially available handsets or mobile stations (MS) based on, e.g., CDMA, AMPS, NAMPS or TDMA communication standards, for processing both local MS location requests and more global MS location requests via, e.g., Internet communication between a distributed network of location centers. The system uses a plurality of MS locating technologies including those based on: (1) two-way TOA and TDOA; (2) pattern recognition; (3) distributed antenna provisioning; (5) GPS signals, (6) angle of arrival, (7) super resolution enhancements, and (8) supplemental information from various types of very low cost non-infrastructure base stations for communicating via a typical commercial wireless base station infrastructure or a public telephone switching network. Accordingly, the traditional MS location difficulties, such as multipath, poor location accuracy and poor coverage are alleviated via such technologies in combination with strategies for: (a) automatically adapting and calibrating system performance according to environmental and geographical changes; (b) automatically capturing location signal data for continual enhancement of a self-maintaining historical data base retaining predictive location signal data; (c) evaluating MS locations according to both heuristics and constraints related to, e.g., terrain, MS velocity and MS path extrapolation from tracking and (d) adjusting likely MS locations adaptively and statistically so that the system becomes progressively more comprehensive and accurate. Further, the system can be modularly configured for use in location signing environments ranging from urban, dense urban, suburban, rural, mountain to low traffic or isolated roadways. Accordingly, the system is useful for 911 emergency calls, tracking, routing, people and animal location including applications for confinement to and exclusion from certain areas.

A hybrid media storage architecture has a log-structured file system configured to control a plurality of different storage media organized as hybrid storage media that cooperate to provide a total storage space of a storage system.

By defining and implementing heuristics and policies directed to, e.g., types of data, the file system may initially place data on any of the different media and thereafter migrate data between the media at fine granularity and without the need for manual enforcement.

A method, system, and apparatus are directed towards selectively concatenating data into a packet to modify a number of packets transmitted over a network based on a combination of network and/or send-queue metrics. In one embodiment, Nagle's algorithm is used for concatenating data into a packet. The concatenation may be selectively enabled based on heuristics applied to the combination of metrics. In one embodiment, the result may indicate that there should be a concatenation, or that data should be sent immediately, or that a current state for whether to concatenate or not should be maintained. The heuristics may include an expert system, decision tree, truth table, function, or the like. The heuristics may be provided by a user, or another computing device. In another embodiment, the concatenation may be enabled based on a conditional probability determined from the combination of metrics.

A computer-implemented method for double auction trade-building by matching, based on feasibility and price/cost heuristics, a plurality of electronically posted bid with a plurality of electronically posted ask records. A one-pass sequential trade building method selects ask records one at a time and sequentially inserts, in one pass, as many of the bid records as possible while maintaining feasibility criteria. A two pass sequential trade building method inserts the bid records in two stages, the first terminating when the trade becomes feasible and the second when no further bids can be inserted.

A method and apparatus for reducing the workload of titrating drug to effect while leaving clinician users in control of a related procedure is described. A drug delivery device is controlled to achieve a target drug concentration at a selected site in the patient or a predetermined infusion rate waveform. The time profile of the target drug concentration or a predetermined infusion rate waveform is controlled by a drug state model that uses clinical heuristics to implement safe, pre-defined changes in the target drug concentration or infusion rate and user-commanded changes in target drug concentration or infusion rate. The invention allows time to assess the response of the patient to changes in drug level by making small incremental and conservative changes in drug level over time.

The present invention provides value to brand owners, retailers, and consumers through the use of radio frequency identification, stenography, nanolithography, fingerprints, novel heuristic threat evaluation, indication, and detection model.

Systems and methods for data analysis and trend prediction. Multiple networks are combined for analysis to improve the accuracy of the evaluation by broadening the type of criteria considered. Relevant features are extracted from a dataset and at least one network is formed representing various relationships identified among the items contained in the dataset according to heuristics. Statistical analyses are applied to the relationships and the results output to a user via one or more reports to permit a user to evaluate each of the items in the dataset relative to each other. The trend of the relationships may be predicted based on the results of statistical analysis applied to the features over successive discrete time periods.

A modular scoring system using rank aggregation merges search results into an ordered list of results using many different features of documents. The ranking functions of the present system can easily be customized to the needs of a particular corpus or collection of users such as an intranet. Rank aggregation is independent of the underlying score distributions between the different factors, and can be applied to merge any set of ranking functions. Rank aggregation holds the advantage of combining the influence of many different heuristic factors in a robust way to produce high-quality results for queries. The modular scoring system combines factors such as indegree, page ranking, URL length, proximity to the root server of an intranet, etc, to form a single ordering on web pages that closely obeys the individual orderings, but also mediates between the collective wisdom of individual heuristics.

A method and a system for making merging decisions for a translation are disclosed which are suited to use where the target language is a productive compounding one. The method includes outputting decisions on merging of pairs of words in a translated text string with a merging system. The merging system can include a set of stored heuristics and/or a merging model. In the case of heuristics, these can include a heuristic by which two consecutive words in the string are considered for merging if the first word of the two consecutive words is recognized as a compound modifier and their observed frequency f₁ as a closed compound word is larger than an observed frequency f₂ of the two consecutive words as a bigram. In the case of a merging model, it can be one that is trained on features associated with pairs of consecutive tokens of text strings in a training set and predetermined merging decisions for the pairs. A translation in the target language is output, based on the merging decisions for the translated text string.

In further embodiments, the control circuitry can optimally combine write commands from a buffer with write commands from a queue. After combining the commands, the control circuitry can dispatch the commands in a single transaction.

A crawler collects webpage data and obtains a list of URL's of interest used to construct a searchable index. The HTML stream is received for each relevant URL and each HTML stream is imported onto a browser or rendering engine so as to render the page. From the browser, the run-time data structure for each page is obtained. From the run-time data structure, layout information of the webpage is obtained. The layout information can include location and size of images, text, video clips, banners, etc. Using various heuristics, selected items of interest are identified as relevant according to their associated layout information. Then, when a query is received and a match is found in the index, only the information identified as relevant is fetched and presented to the user.
