Abstract: A portable device receives content from a computer and a signature certificate. The signature certificate is derived from content after the content successfully passes a watermark screening process. The portable device compares the received signature certificate to the received content. The content is only played in the portable device when the received signature certificate authenticates the received content as passing the watermark screening process.

Abstract: Content is authenticated by generating signature certificates for content that has been successfully watermark screened. When a request is received for importation of content into a secured domain, a search is made in a signature certificates cache for a signature certificate associated with that requested content. If an identified signature certificate authenticates the requested content, the content is imported into the secured domain. If no signature certificate is identified, the content is watermark screened. If the content successfully passes the watermark screening process, a new signature certificate is then added to the signature certificate cache.

Abstract: A page table method that allows programming of flash memory without corrupting the translation lookaside buffers is described. Flash memory is used to store page tables and other data. In one embodiment of the invention, the page tables are shadowed in random access memory after system bootup to prevent the system from crashing in the event the page tables are accessed while the read only memory is being programmed. In a second embodiment of the invention, the translation lookaside buffers are pre-charged.

Abstract: This patent pertains to reduced oil fried foods with acceptable taste, texture and appearance may be achieved by applying a hydrocolloid to the food, crosslinking such hydrocolloid, and coating the food with a starch product prior to frying.

Abstract: A Stirling cycle engine comprises a substantially sealed engine block that defines a working fluid space, a hot path and a cold path. A heat source and a heat sink are configured to keep the hot path and the cold path at different temperatures. The engine includes a valve chamber that is communication with the working fluid space, the hot path and the cold path. A valve is moveably positioned within the valve chamber between at least a first position and a second position. The valve defines a passage that, in the first position, places the working fluid space in communication with the hot path and, in the second position, places the working fluid space in communication with the cold path. A regenerator positioned within the passage.

Abstract: The present invention is directed to a system and method which allows a user to easily find a desired community or discussion category that pertains to a topic of interest to the user. A preferred embodiment of the invention involves a hierarchical structure for a plurality of communities and a matching engine that essentially only searches the plurality of communities. It is preferable to allow any user to extend the structure by adding new keywords and links and new communities by indexing existing or newly created communities.

Abstract: A method for configuring a network appliance with instructions sent by e-mail. A mail recipient on the appliance, either a mail client or a mail server, receives an e-mail containing instructions. The appliance then configures itself according to the instructions. The instructions may be parsed into instructions at the appliance or the instructions may arrive in a command format that does not require parsing. The appliance may have a persistent network connection or may connect to the network occasionally.

Abstract: An adapter for providing network access to a shared image projection device may comprise a network interface for connecting to a network and receiving network data from a network device over the network. A client, operatively associated with the network interface, receives data from the network interface and produces a data signal. A video display driver, operatively associated with the client, receives the data signal and produces video data for the shared image projection device.

Abstract: A way of controlling sharing of files by portable devices is provided. A portable device is provided that comprises an interface to receive at least one file and a transfer count associated with the file from another device. The portable device further includes a controller that is communicatively coupled to the interface, the controller to allow transfer of the file based on the associated transfer count.

Abstract: The present invention relates to a system and method for sharing resources between workstations separated by security measures such as firewalls by employing electronic mail messaging and attachments thereto to transmit tasks and/or functions through firewalls for execution at a destination workstation. A dedicated lightweight SMTP server is preferably deployed at destination workstations to operate on incoming email messages associated with tasks for execution at such workstations.

Abstract: A digital music player. The player includes a memory capable of storing music files. The player has a user interface allowing a user to select and access the music files. A port on the player allows the user to establish a connection to other digital music players. The user can then send and receive music files without an intervening host.

Abstract: A method for managing a storage medium includes searching the storage medium for a first file having a reference to a second file that has moved to a new location on the storage medium. The reference is updated such that it indicates that the second file has moved to the new location.

Abstract: An enzymatic process for preparing an oil based product significantly enriched in omega-3 fatty acids is disclosed. The process is a two-step procedure involving lipase-catalyzed transesterification of triglycerides followed by low-temperature crystallization. The process yields a mixture of highly pure monoglycerides, at least sixty-percent of which contain omega-3 fatty acids. The process can also be used to produce omega-3 enriched triglyceride products.

Abstract: The present invention pertains to a novel starch-based opacifying agent, to methods of manufacture and to food and non-food formulations containing the opacifying agent. The starch-based opacifying agent comprises an opacifier (e.g., titanium dioxide) and starch in the form of a complex in which the opacifier has been stabilized or entrapped therein. The opacifying agent can be used in low fat and fat-free foods and beverages, including coffee creamer, cottage cheese dressing, nutritional beverages, mayonnaise, sour cream, ice cream, yogurt, salad dressing and other foods and beverages that need to be opacified. The opacifying agent can also be incorporated into non-food formulation, such as cosmetics, creams and lotions.

Abstract: Texturized oils and oil-continuous emulsions are prepared by combining liquid oils with edible polymers. The resulting texturized oils and emulsions are gelled substances having a fat-like consistency which approximates the viscoelastic properties of solid fats, such as butter, margarine or hydrogenated vegetable oils, but contain no saturated fats. These texturized oils and emulsions can be used as a substitute for solid fats in food products and to make high-quality spreads containing reduced amounts of saturated fat.

Abstract: Water-dispersible microparticles of hydrophobic, water-insoluble, non-denatured protein, and method for preparing a suspension of these microparticles by the controlled precipitation of the protein, is described. The suspension can be used as a substitute for most dietary fats, or to encapsulate selected molecules. The water-insoluble proteins used in the process can be chemically or enzymatically modified to enhance the properties of the microparticles.
