Abstract:
A system, method and computer readable storage medium that receives traffic/packets from external devices attempting to access protected devices in a protected network. A determination is made to whether a received packet belongs to one of a plurality of packet classifications. Each packet classification indicative of different classes of IP traffic. Countermeasures are applied to a received packet to prevent attack upon the protected devices. Applying a countermeasure to a received packet determined to belong to one of the plurality of packet classifications includes countermeasure modification/selection contingent upon the determined packet classification for the received packet.
Abstract:
A method and system for streaming dynamically generated Zip archive file content using a standard, non-streaming Zip archive format. In response to a request from a client to receive one or more files, a Zip archive file is dynamically generated that includes at least one file that is altered while servicing the request, wherein the size of the altered file is unknown prior to completion of the alteration operation. For a Zip file entry corresponding to an altered file, a local file header including an overestimated file size and predetermined CRC32 value is generated. After alteration, the file entry content is adjusted using padding and a CRC32 adjustment such that the length and CRC32 values for the resulting Zip file entry match the overestimated file size and predetermined CRC32 value. Examples of file alteration operations include watermarking, compressing, and/or encrypting the file content.
Abstract:
A collaboration system described herein empowers non-technical users to create and manage custom collaboration portals, called hubs. Hubs are easy to manage, often providing a satisfactory default configuration after the user answers questions through a wizard-like interface. The collaboration system may be provided as an Internet-based service that can be accessed by users regardless of their affiliation with a company or other predetermined group. In addition, the system shields users from the systems that provide storage for hub content, so that users can avoid the difficulties of data management. The system may provide one or more hub widgets that provide specific functionality, such as a calendar widget for managing events, a file widget for sharing files, a comments widget for managing electronic discussions, and so forth. Thus, the collaboration system facilitates online collaboration for users without advanced software experience.
Abstract:
A device for monitoring movement of an object is provided. A first module is configured to secure to the object. A second module, capable of electrically connecting to the first module, includes at least a rechargeable battery and a memory capable of storing a history of movement data. A third module, capable of electrically connecting with the second module, includes a data modem capable of connecting to a remote station, and a battery charger. When the second module is connected to the first module, the memory periodically records available location data representing a position of the device at the time of recording. When the second module is connected to the third module, the memory downloads through the data modem and the battery charger charges the battery.

Abstract:
A client computer runs an operating system that executes additional applications by loading them using an application loader and executes device drivers for peripheral devices by loading the drivers using a device loader. The operating system restricts the functionality of the operating system, such as by making selected portions and functionality of the operating system unavailable to the user or by limiting the user's ability to add software applications or device drivers to the computer. Additionally, various techniques can be used to remove or reduce the functionality limitations of the computer

Abstract:
A method for encoding network data, such as Internet Protocol (IP) data, into a format for transmission over a satellite system is described. The network data is configured in a packet having a data block and header information. The network data packet is encoded into a variable-length multi-packet transport (MPT) frame. The MPT frame comprises a data frame to hold data and header information. The IP packet in inserted its entirety into the data frame of the MPT frame. The variable-length MTP frame is then encoded into one or more fixed-length MTP packets. Each MPT packet has a data fragment block comprising a portion of the MTP frame and associated header information to designate what portion of the MTP frame is contained in the data fragment block. The MPT packets are sized to be embedded as a specific size payload of the satellite packet that is transmitted over a satellite network. Using this method, data received over a data network (i.e., Ethernet or Internet) in large network data packets are broken into smaller packets defined by the multi-packet transport. These smaller packets are then inserted as the data payload within standard fixed-size packets suitable for transmission across a particular distribution medium, such as satellite network. The network data remains independent of the underlying network and can be easily extracted at the receiver for use by computer applications.
Abstract:
A client computer collects registration information regarding a user and/or the client computer and attempts to upload the collected information to a remote registration system. The client computer stores the registration information locally and delays uploading of the information to the registration system until a connection to the registration system is established. The connection to the registration system and the uploading of the registration information can be performed automatically and transparently to the user, eliminating the need for any further required actions on the part of the user once the registration information is collected.
Abstract:
A visualization system for enabling a user to select a vehicle and to overlay images of various user-selected accessories onto an image of the vehicle to cause a computer to display an image of the desired combination includes a database that stores digitized images of various vehicles and accessories. The accessories can be photographed separately from the vehicle, so that it is not necessary to photograph an accessorized vehicle for each one of the potentially thousands of vehicle/accessory combinations. The database correlates accessories and colors, with prices and other data, to the relevant vehicles. An Internet user can access the database over the Internet to select a vehicle with user-defined accessories, and then a composite image of the vehicle with accessories is presented to the user. Or, a salesperson in a dealership can access a local database of vehicles/accessories to display, on a monitor in the showroom, a composite photograph of a vehicle with a buyer-defined suite of accessories, such that the buyer can visualize the desired vehicle/accessory combination even if an actual vehicle with the desired accessory suite is not on the lot.
