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.

Method, system and computer program product for detecting at least one of security threats and undesirable computer files are provided. A first method includes receiving a data stream which represents outbound, application layer messages from a first computer process to at least one second computer process. The computer processes are implemented on one or more computers. The method further includes monitoring the data stream to detect a security threat based on a whitelist having entries which contain metadata. The whitelist describes legitimate application layer messages based on a set of heuristics. The method still further includes generating a signal if a security threat is detected. A second method includes comparing a set of computer files with a whitelist which characterizes all legitimate computer files. The whitelist contains one or more entries. Each of the entries describe a plurality of legitimate computer files.

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. The log-structured file system is configured to perform initial placement and migration of data, as well as fine-grain write allocation of the data, among storage space locations of the hybrid storage media to thereby improve the performance characteristics of the media. 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 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.

In some embodiments, a server for creating photo-based projects is disclosed. The server executes a method for establishing a client-server connection between the server and a user-operated computer connected to the network, receiving images from the computer and storing the images in the a data repository, receiving a use-case identifier, performing photo analysis on the images, comprising: identifying similar images, identifying faces in the images, identifying objects in the images, identifying undesirable images and identifying relevant portions of the images, performing use-case specific heuristics on the images, comprising: grouping similar images, grouping images having identical faces, grouping images having identical objects, removing undesirable images, and cropping images to highlight relevant portions of said images, and, generating an ordered project subsequent to execution of the use-case specific heuristics, wherein the ordered project comprises the images placed in a particular order and pre-processed for printing in book form.

Systems and methods are disclosed for efficient buffering for a system having non-volatile memory (“NVM”). In some embodiments, a control circuitry of a system can use heuristics to determine whether to perform buffering of one or more write commands received from a file system. In other embodiments, the control circuitry can minimize read energy and buffering overhead by efficiently re-ordering write commands in a queue along page-aligned boundaries of a buffer. 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.
