摘要:
A home agent, attached to a home network, receives, adapts and forwards messages intended for a mobile node attached to one of a plurality foreign networks. The home agent, having received a message, passes the message on to a processing unit to assess whether the message should be adapted so as to be compatible with the destination foreign network and to adapt the message accordingly. The adapted message is returned to the home agent to be encapsulated and tunnelled to a foreign agent attached to the destination foreign network. The foreign agent decapsulates the message and passes it on to the mobile node. This method has the advantage that the mobile node is able to receive messages regardless of the type of network to which it is attached.

A system and method for updating a filtering system which controls access to a website/page between a local area network (LAN) and an Internet. The LAN includes an Internet gateway system coupled to a workstation and configured to receive a URL request. The system controls access to the website/page associated with the URL based on one or more categories that are associated with the URL. The Internet gateway system can determine the category that is associated with the URL by referencing a master database or requesting the category from a database factory. The database factory can receive URLs from multiple Internet gateway systems. The database factory determines whether the identifier was previously categorized by the database factory and provides the category to the Internet gateway system. Once the Internet gateway system has the category, it applies rules associated with the category and user to filter access to the requested website/page.

A blast resistant window structure capable of withstanding typical car bomb blast pressures of 100 psi or more and of resisting leakage of chemical or biological agents is described, the window structure including a frame hermetically enclosing two glass panels in confronting relationship defining an air gap therebetween, each glass panel having a thin layer of polymer film on each surface thereof, and a pressure relief valve in the frame for releasing air pressure from within the gap in response to blast pressure imposed on an outer surface of one of the panels.

An apparatus for controlling the position of a screen pointer for an electronic device having a display screen includes a light source for illuminating an imaging surface, thereby generating reflected images. The apparatus includes a single chip for receiving the reflected images, generating digital representations of the reflected images, and generating a first set of movement data based on the digital representations of the reflected images. The first set of movement data is indicative of relative motion between the chip and the imaging surface. The single chip includes a serial interface for outputting motion data in a serial format based on the movement data.

Laser power control arrangements interrupt power to a laser used in electro-optical readers upon detection of operating conditions not conforming to preestablished standards, and adjust power to the laser to enhance reader performance without violating prevalent safety standards.

A user of a client device selects a service provider from a plurality of available service providers. The client device then queries the user for the user's information and formats the user's information into a predetermined data structure and format. The client device connects to the service provider and sends the formatted user's information to the service provider. The service provider responsively creates configuration data and provides it to the client device. The configuration data is used to configure a plurality of applications on the client device, allowing the user to establish future communication sessions with the service provider.

An apparatus and method enable parallelism in a computer program using parallelism that is built-in to many modem database managers. The parallelism provided by a database manager in executing user-defined functions provides an easy way to implement parallelism for database and non-database functions in a computer program without the need of hard-coding all the parallelism support in the computer program itself. A database table is defined with instructions the user wants to execute in parallel. A user-defined function is then defined that executes the instructions in the table. A database operation is then defined for the table that invokes the user-defined function. When the database operation is executed, the database manager provides parallelism by executing multiple tasks in parallel in the user-defined function. The built-in parallelism in many modem database managers thus may be used to enable parallelism in a computer program by using user-defined functions in a manner not previously thought of before.
摘要:
An imaging apparatus including a photo sensor array having an array of sensors is disclosed, each sensor having an active area and a support hardware area adjoining the active area. In the prior art, the support hardware area of each sensor adjoins the active area of the sensor in the same direction. In the present invention, a sensor array has an array of sensors where, for each sensor, the support hardware area adjoins the active area of the sensor in a direction that is radially away from center of the sensor array whereby at least one freed area is defined within the sensor array. One or more reference detectors can be fabricated in the freed areas. This design allows the imaging apparatus to gather better image statistics, overcome shortcomings of the prior art design, or both.

A process for producing photonic crystals comprises (a) providing a substantially inorganic photoreactive composition; (b) exposing, using a multibeam interference technique involving at least three beams, at least a portion of the photoreactive composition to radiation of appropriate wavelength, spatial distribution, and intensity to produce a two-dimensional or three-dimensional periodic pattern of reacted and non-reacted portions of the photoreactive composition; and (c) removing the non-reacted portion or the reacted portion of the photoreactive composition to form interstitial void space.

A CAD/GIS system that automatically discovers hierarchical relationships between root faces/parcels, smaller faces/parcels, and other defined areas of land. As the definitions are entered into the system, hierarchical relationships are created by the system to ease data management functions.
