6699 results about "Time sequence" patented technology

Most commonly, a time series is a sequence taken at successive equally spaced points in time. Thus it is a sequence of discrete-time data. Examples of time series are heights of ocean tides, counts of sunspots, and the daily closing value of the Dow Jones Industrial Average.

Method for radio resource control

In order to control the use of physical radio resources, the physical radio resources are divided into chronologically consecutive frames (14), so that a frame contains slots (16, 17, 18) of various sizes, which slots represent a given share of the physical radio resources contained in the frame and can be individually allocated to different radio connections. The first dimension of a frame is time and the second dimension can be time, frequency or code. In the direction of the second dimension the slots represent various sizes, and a given first integral number of slots of the first size can be modularly replaced by another integral number of slots of another size. A certain number of consecutive frames form a superframe (19), in which case frames with corresponding locations in consecutive superframes are equal in slot division and allocations, if the data transmission demands do not change. Changes in the state of occupancy of the slots are possible at each superframe. In order to form an uplink connection, the mobile station sends a capacity request, where it indicates the type of requested connection and the demand of resources. In order to form a downlink connection, the base station subsystem sends a paging call, where it indicates the location in the superframe of the slots allocated to the connection. In order to indicate the state of occupancy, the base station subsystem maintains a superframe-size parametrized reservation table.

Method and apparatus for an intruder detection reporting and response system

A method and apparatus is disclosed for improving the security of computer networks by providing a means operating passively on the network for detecting, reporting and responding to intruders. The system is comprised of a plurality of intruder sensor client computers and associated event correlation engines. Resident in the memory of the client computer and operating in the background is a Tactical Internet Device Protection (TIDP) component consisting of a passive intruder detector and a security Management Information Base (MIB). The passive intruder detector component of the TIDP passively monitors operations performed on the client computer and emits a Simple Network Management Protocol (SNMP) trap to an event correlation engine when it identifies a suspected intruder. The event correlation engine, through the use of a behavior model loaded in its memory, determines whether the user's activities are innocent or those of a perspective intruder. When the event correlation engine is unable to classify a user based on a single trap message, it can request historical information from the security MIB, a database of the operating history of the client computer including a chronology of the illegal operations performed on the client. Once the event correlation engine determines that an intruder is located at an associated client workstation, it generates a status message and transmits the message to all of its subscribers, informing them of the presence and location of a suspected intruder.

System and method for visualizing connected temporal and spatial information as an integrated visual representation on a user interface

As data about events and objects become more commonly available, analyzing and understanding of interrelated temporal and spatial information is increasingly a concern for military commanders, intelligence analysts and business analysts. A system and method is provided for creating a multidimensional visual representation of a group of data elements having integrated temporal and spatial properties. The data elements are included in the visual representation as corresponding visual elements, such that the data elements of the group linked by at least one association. The system includes a visualization manager for assembling the group of data elements using the at least one association and for assigning a connection visual element in the visual representation between a first visual element representing a first data element of the group and a second visual element representing a second data element of the group. The system also has a spatial visualization component, such as a sprite, configured for generating a spatial domain of the visual representation to include a reference surface for providing a spatial reference frame having at least two spatial dimensions. The reference surface is for relating the first visual element to a first location of interest in the spatial reference frame and for relating the second visual element to a second location of interest in the spatial reference frame. The system also has a temporal visualization component, such as a sprite, configured for generating a temporal domain of the visual representation operatively coupled to the spatial domain, the temporal domain for providing a common temporal reference frame for the locations of interest. The temporal domain includes a first time track, such as a timeline, coupled to the first location of interest and a second time track coupled to the second location of interest, such that the first visual element is positioned on the first time track and the second visual element is positioned on the second time track. Each of the time tracks configured for visually representing a respective temporal sequence of a plurality of the data elements at each of the locations of interest of the reference surface. In implementation of the method, the connection visual element represents a distributed association in at least one of the domains between the first visual element and the second visual element such that the visual representation is displayed on a user interface for subsequent interaction with user events, including animation of the visual elements to help in the analysis of the data contained in the visual representation.

Geographic information storage, transmission and display system

A system is disclosed in which a geographic area of interest can be selected, and information corresponding to the selected area can be downloaded and displayed by a user in an efficient and timely manner. The geographic area of interest may initially be selected by various input means such as a map, longitude/latitude coordinates, a global positioning system (GPS), and the like. Once the particular geographic area has been selected, geographic information corresponding to the selected area is downloaded to the user. The geographic information may include photographic images, radar, radio transmission, cell phone transmission, time sequenced images, ground moving target information, air moving target information, maritime moving target information, red or blue force identification and/or potential hazard areas information. The geographic information may be stored in a suitable data storage system such as a server. Alternatively, the geographic information may be generated real time and downloaded to the user. In one embodiment, the geographic information includes photographic images and a relatively low resolution image of a large geographic area is initially displayed to the user. The user can then select a limited region of the photographic image for closer viewing. The limited region of the photographic image may then be downloaded to the user in a higher resolution format, thereby reducing the amount of high resolution data that must be transmitted to the user. Various display devices may be used, such as personal data assistants (PDAs), laptop computers, desktop computers, vehicle-mounted computers, tablets, cell phones and the like. The display device may also be used as the input device to both select the geographic area of interest and display the photographic images or other geographic information of the selected area.

Power distribution network double layer planning method considering the time sequence and the reliability

The invention relates to a power distribution network double layer planning method considering the time sequence and the reliability. The method comprises: according to the meteorological files and the load power statistical data, obtaining the typical daily power time sequence curves of the wind electricity, the photovoltaic output and the load in different seasons; based on the opportunistic constraint planning method, creating a power distribution network framework and a distributed power capacity double layer planning mathematical model, including the objective function and the constraint condition; using the particle swarm optimization algorithm to solve the model and using the minimum spanning tree algorithm to ensure the radiation and connectivity structure of the distribution network during the iterative process; and obtaining the target network framework and the Pareto optimal solution set of the distributed power capacity so as to generate the best planning scheme. The invention solves the problems that unnecessary investment into the a power distribution network incurred by the fact that a traditional power distribution network planning method containing a distributed power supply cannot reflect the typical output characteristic of a distribution type new energy; and 2) that by incorporating the power distribution network power supply reliability into a model target function, the reliability target can be realized at the planning stage.

Synchronous task scheduler for corba gateway

A system and method for a synchronous task scheduler. The synchronous task scheduler may be used with a CORBA Gateway between CORBA-based client manager applications and an enterprise manager. The CORBA Gateway may include components such as an Event Gateway which manages events from managed objects, and a Request Gateway which manages requests and responses of managed objects. The Event Gateway and the Request Gateway may be designed as multi-threaded systems. A thread pool may be used to increase efficiency and performance of the CORBA Gateway. To ensure ordered delivery of events or replies to the CORBA gateway clients in a multi-threaded environment using a thread pool, a synchronous task scheduler may be used. There may be a synchronous task scheduler associated with each client manager to preserve the chronology of messages sent to each. The synchronous task scheduler may maintain an internal message list, and deliver one message at a time from that internal list. The synchronous task scheduler may hold a reference to a thread pool and use that thread pool to deliver messages. When a message is scheduled, the synchronous task scheduler may check if any message is already being delivered. If no prior message is currently being delivered, an available thread may be assigned from the thread pool for delivery of the message and the scheduler may initiate delivery of the message. If a prior message is being delivered, it may enqueue the message in the message list. Then, when the prior message delivery is completed, the scheduler may dequeue the message, assign another thread from the thread pool, and initiate delivery of the message. This may continue until the message list is empty.
