Abstract: A power line conditioner using cascade multilevel inverter used for voltage regulation, reactive power (var) compensation and harmonic filtering, including the control schemes for operating the cascade inverter for voltage regulation and harmonic filtering in distribution systems. The cascade M-level inverter consists of (M-1)/2 H-bridges in which each bridge has its own separate DC source. This new inverter (1) can generate almost sinusoidal waveform voltage with only one time switching per line cycle, (2) can eliminate transformers of multipulse inverters used in the conventional static VAR compensators, and (3) makes possible direct connection to the 13.8 kV power distribution system in parallel and series without any transformer. In other words, the power line conditioner is much more efficient and more suitable to VAR compensation and harmonic filtering of distribution systems than traditional multipulse and pulse width modulation (PWM) inverters.

Abstract: A method for efficiently updating and displaying the hierarchy of a remote data store and displaying subfolder indicia indicating that child folders contain at least one subfolder. When a user expands a folder, an e-mail client displays a cached list of the expanded folder's contents. After the cached data is displayed, a list of the expanded folder's child folders and a list of the subfolders contained in the child folders are retrieved from the remote mail server. The retrieved data is sorted and compared to the cached list, and the cached data is updated to reflect the correct child folders and whether the child folders contain subfolders. The displayed hierarchy is then updated to reflect the state of the data that was retrieved from the server.

Abstract: A method and system for monitoring the operational status of a network element in an advanced intelligent network is provided. Custom telecommunications services, such as a call forwarding service, are processed by routing a call to a network element, such as a service circuit node, that processes the call and provides the custom telecommunications service. When the network element or application software resident at that network element fails, calls routed to that network element may be mishandled. The method and system of the present invention utilize advanced intelligent network services to monitor a desired network element prior to routing a call to that network element for custom telecommunications service. A heartbeat message is utilized between a monitored network element and a monitoring network element. The method and system reduce network element downtime by alerting maintenance personnel of network element or application software failure.

Abstract: A scheme for depositing a private key used in the RSA cryptosystem which is capable of maintaining the private key more safely, without requiring a user to always carry around a storage medium. In this scheme, a private key of a user is divided into a first partial private key and a second partial private key at a user's entity, where the first partial private key is set to be maintained at the user's entity, while the second partial private key is deposited from the user's entity to the other entity. Then, the second partial private key is delivered from the other entity to the user's entity in response to a request from the user's entity, and the first partial private key maintained at the user's entity and the second partial private key delivered from the other entity are composed so as to obtain the private key to be used in a processing according to the RSA cryptosystem at the user's entity. This scheme can be generalized to a case of dividing the private key into a plurality of partial private keys.

Abstract: The present invention is a method for producing a nonwoven fabric from a water modifiable polyolefin-containing film. In order to produce the fabric where polyethylene is the minority constituent, a polymer blend is formed with the polyethylene as the dispersed phase and polyethylene oxide as the continuous phase. In another embodiment wherein the polyethylene is the majority constituent and the polyethylene oxide is the minority constituent of the film, a reactive blend created during processing exhibits an inverse phase morphology so that the polyethylene oxide becomes the continuous phase and the polyethylene becomes the dispersed phase. In either embodiment, the film is then treated with an aqueous solvent to remove the polyethylene oxide to produce the nonwoven, porous fabric. The resulting nonwoven, porous fabric has a silk-like hand and shine ideal for disposable personal hygiene articles, and is flushable through waste water disposal systems.

Abstract: Providing data services using idle cell capacity in a cellular communications system. The system and method assign priorities to each remote user device in the cellular communications system. In response to a request for service for a remote user device, the mobile switch determines whether an idle channel is available for the remote user device. If no idle channel is available, the mobile switch determines whether a remote use device with a lower priority than the requesting remote user device is using a channel. If a lower priority remote use is using a channel, its call is terminated and the channel is assigned to the requesting remote user device. If no lower priority remote user device is using a channel, the request for service is put into an ordered queue to wait for the next available idle channel.

Abstract: A Menu Building Component (MBC) builds menus during a computer's idle time. The MBC builds a menu for each menu title on a Menu Bar and stores each built menu in the computer's random access memory (RAM). The MBC requests an allocation of idle time by registering with a Component Manager. The Component Manager notifies the MBC of the availability of idle time by sending a notification signal to the MBC. When the MBC receives the notification signal, the MBC builds the next unbuilt menu corresponding to a menu title on the Menu Bar. When the last menu has been built, the MBC unregisters with the component manager. If a user makes a menu demand for an unbuilt menu, the MBC will build the demanded menu on demand, rather than during an idle time. If the user makes a menu demand for a built menu, the built menu is recalled from RAM and displayed for use by the user. Because the MBC builds menus during idle times, start-up delays and menu demand delays are minimized.
