Appl. No.:

10/427082

Inventors:

Peter Pham - San Jose CA, US

International Classification:

G06F015/16
G06F017/00
G06F007/00

US Classification:

707/002000, 709/203000, 707/104100

Abstract:

A method and apparatus for transparently linking keywords displayed in a document viewer on a display monitor attached to the said computer system to information on a remote web-based information retrieval system (or web site) comprises of an access agent executing on a computer system. The said web site is coupled to the said computer system over a computer network and executes a keyword lookup server as a server-side program (CGI) for providing a keyword-based information retrieval service which is remotely accessible using standard Universal Resource Locator (URL) web access method (or HTTP). The said access agent installs one or more input device handlers for intercepting and scanning user input for one or more pre-configured hot key. Each of the said hot keys is mapped to one or more URLs which contain a special marker to be replaced by a keyword selected by the user and is used to access the said lookup service for retrieving information associated with the said user-selected keyword. The user selects the said keyword displayed in a document viewer by highlighting it or positioning an input device's cursor on or at it and then applies a said hot key. The said hot key consequently triggers the said access agent to retrieve the said URL associated with the said hot key and the said user-selected keyword from the display buffer associated with the said document viewer window. Next, the said access agent replaces the special marker in the said URL with the said user-selected keyword and then invoke a web browser using the said URL for retrieving information associated with the said keyword and handling the retrieved information.

US Classification:

351239000, 600558000, 351246000

Abstract:

An automated unaided virtual perimetry system and underlying method for relative-threshold contrast sensitivity interrogation of the visual field via algorithmic presentation of visual stimuli on a screen and subsequent analysis of test response data for the detection of pathophysiologic scotomas as well response time registration and analysis for visual motor reflex testing. Launch of system via access from a remote server or direct installation of systems technology allows seamless capability at the local computer system to instruct, administer, and analyze output of stimuli and input of responses of test subjects or subjects independent of external input or control. Specific algorithmic test environment is designed to achieve comparable clinical efficacy and diagnostic utility to office-based perimetry system.

International Classification:

H04L 29/08
H04L 12/26

Abstract:

A proxy processing device and associated method are provided to receive control signals from a manager that are based on user input received by the manager. Further, the control signals are sent to an agent for controlling one or more aspects of a collection of data from at least one node and a communication of the data to a destination via at least one channel. The collection of the data and the communication of the data is performed by the agent utilizing a plurality of software components that each customizes the one or more aspects of the collection of the data and the communication of the data.

Peter T. Pham - Hollister CA, US

International Classification:

G06N 5/02
G06N 7/00

Abstract:

An example method comprises receiving a first data stream regarding performance of a monitored system at a first time, determining a plurality of distributions from the first data stream using a density function of a plurality of bins for the data, identifying at least one state for each different distribution of the plurality of distributions to identify a plurality of states, classifying each of the plurality of states into classifications, identifying at least one of the plurality of states as being a problematic state using a first log likelihood ratio, for each state recognizing one or more transitions from or to other states of the plurality of states, receiving a second data stream of the monitored system at a second time, identifying a precursor state indicating at least a potential future transition to the-problematic state, and generating a warning before the monitored system enters the problematic state.
