Abstract: A method for improving an RSA cryptosystem by generating a user private exponent key, having an associated modulus N, and a user public exponent key for each user of the system. Each user's public exponent key is provided to all users of the system. Each user's private exponent key is divided into a two user key portions. A first user key portion is maintained exclusively by the user for whom the associated private exponent key was generated. A second user key portion is entrusted to one or more other users of the RSA system. The bit length of the first user key portion is no greater than fifteen percent of the bit length of the associated modulus N but not less than 56 bits. The two portions of the private exponent key may be used by two users to exchange two numbers, the product of which is used as a session key to secure communications between the two users. The portions of the private exponent key may also be used by different users to verify the identity of each to the other.

Abstract: A perforate current collector element (21) embedded within at least one of its polymeric intercalation electrodes (23) reduces the internal resistance of a flexible rechargeable lithium-ion battery (20).

Abstract: In accordance with the present invention, data is transmitted through a network in chunks. Chunks are self-describing units designed for high speed protocol processing. Packets act as envelopes for carrying chunks across a network. The self-describing nature of chunks allow them to be processed as they arrive at the receiver regardless of any misordering. The ability to process data without intermediate buffering for reordering or reassembly improves protocol processing performance. The chunks also distribute protocol data units control overhead over multiple packets.

Abstract: A broadband service control point provides processing instructions and data to a broadband session controller and an information sender/receiver. The broadband session controller communicates with a user's settop controller and video information providers, ("VIPs"), and requests processing information from the broadband service control point in response to predetermined triggers. The broadband session controller also instructs the broadband switch network to establish broadband connections between a VIP and a predetermined settop controller. An integrated service control point integrates broadband and telephone networks to provide efficient and effective integrated broadband and telephone services via a video interface at a user's remote location. Also, the integrated network provides unique caller identification delivery services.

Abstract: A system and method are disclosed for transmitting a packet from a source node S in a first stub 300 to a destination node D in a second stub 306 of an internet communications network 200. The first stub 300 is connected with a public data network (PDN) 210 by a first access point node Ra and the second stub 306 is connected with the PDN 210 by a second access point node Rd. The first access point node Ra, writes its PDN subnetwork address in the packet. The first access point node Ra then transmits the packet via a sequence of one or more intermediary access point nodes Rb, Rc on a base path until the packet reaches the second access point node Rd. The second access point node Rd receives the packet via the base path. The second access point node Rd stores the PDN subnetwork address of the first access point node Ra (contained in the packet) in an entry 131 of shortcut table 130 maintained at the second access point node Rd.

Abstract: In advanced digital networks for providing selective point-to-point communications between subscriber's terminals and broadband server's equipment operated by a plurality of independent information service providers, routing through the network is controlled by functionality identified as a Level 1 Gateway. In an enhanced video dial tone network additionally providing an array of broadcast services from multiple providers, the Level 1 Gateway also provides high level control over at least some of the broadcast services. The Level 1 Gateway will perform a variety of functions including communications port management of transmissions of information between subscribers and servers, processing of billing information and session management. The Level 1 Gateway generates menus of providers and broadcast services, either as a function of providers and services available through a particular portion of the network or in a customized fashion specified by individual subscribers.

Abstract: In an Advanced Intelligent Telephone Network system, switching points are programmed to trigger a query to a Service Control Point ("SCP") in response to a dialed "500" number. The SCP performs a data request of an outside database storing service provider information, obtaining a service provider identification or a routing number corresponding to the dialed "500" number. The SCP then transmits a switching instruction to the service system point to route the call to the appropriate destination number.

Abstract: A customer premise equipment (CPE) network integrator (CNI) (20) is connected to today's integrated telephone network to provide additional and improved telephone services. The CNI (20) is connected between a CPE (10) and a network switch (30) and is connected to an STP (40). The CNI (20) detects existing inband call progress network tones, such as dial tone, busy, audible ringback, etc. and a variety of local CPE events, such as offhook, onhook, etc. and uses these tones and events to infer a change in network state. In response to certain network state changes, the CNI (20) queries a network service control point (SCP) (50) and requests call processing information. In response to the call processing information from the SCP (50), the CNI (20) processes the phone call. Because the CNI (20) can infer changes in network states from inband call progress network tones and local CPE events, the CNI (20) can bypass the network switch (30).

Abstract: The error performance of an ATM signaling link operating under the service specific connection oriented protocol (SSCOP) is monitored at the transmitting end of the link by attributing a penalty factor at the end of each polling interval. That penalty factor is determined by whether or not any message was retransmitted in the interval, and whether or not any stat messages transmitted by the receiver in response to each poll were received from the receiver within a predetermined number of polling intervals. At the end of a block of N.sub.-- blk polling intervals, a quality of service (QOS) measure is determined based on the average penalty factor of the block. If the QOS measure is greater than a predetermined threshold, then the link is removed from service. In order to adequately monitor a link with low traffic, the number of stat messages that are are lost within a superblock of N.sub.-- sup polling intervals is determined and if greater than a predetermined number, the link is removed from service.

Abstract: An electrically-conductive collector element (23) in a polymeric laminate lithium ion rechargeable battery is cleaned of surface oxides and coated with an adherent conductive polymer film (34) which is substantially inert to battery electrolyte components and prevents recurrent formation of insulative collector surface oxides, thereby maintaining effective electrode/collector electrical conductivity and significantly reducing internal battery resistance.

Abstract: A scheduling system and method, which employ a token passing scheme, for scheduling transmission of multimedia information between information warehouses (IWHs) and CO clusters (CCs) interconnected by ATM switch(es). Each CO cluster employs a CC schedule processor, which has means for receiving and means for storing requests for multimedia information, means for sorting and prioritizing the requests, means for forwarding requests to appropriate IWHs, and means for accepting or rejecting tokens offered by IWHs in response to a request. The IWH employs an IWH schedule processor which includes means for receiving and means for storing requests from CO clusters, means for selecting a request and generating a token to be sent to the CO cluster originating the request, and means for storing a list of CO cluster rejecting tokens. Requests received from multiple subscribers are stored, sorted, and prioritized at CC schedule processors, which forward the requests to appropriate IWHs.

Abstract: A rechargeable battery comprises a laminate electrolytic cell in which a flexible plasticized polymer hybrid electrolyte/separator layer is interposed between positive and negative electrode layers of lithium-ion intercalating polymeric matrix compositions bearing respective current collector foils. An elongate laminar cell is formed into a unified battery by means of an initial transverse fold disposing one electrode/collector within the structure and with subsequent sequential folds spiralling the cell, without need for interposed insulation, outwardly toward the electrode ends where the collectors accommodate battery terminals. Immersion of the structure in a solvent extracts the polymer plasticizer which is subsequently replaced by contact with lithium salt solution electrolyte to activate the battery.

Abstract: The present invention is directed to a system for the wavelength division multiplexing/asynchronous transfer mode (WDM/ATM) operation of high-capacity optical communication networks. The optical components of the network can transport vast amounts of information, while the ATM-based electronics provides data processing, and information distribution. The capacity of the communications network to reconfigure and rearrange itself is maximized through wavelength translation of its data signals using a limited set of fixed-wavelength channels. The system incorporates an optical fiber communication network ring, or several optical fiber communication network rings that are connected to each other, through which data signals are transmitted and received. Optical WDM cross-connecting switch devices 4a-4e connect adjacent optical fiber rings 3a, 3b to each other, and control the routing of the data signals into and out of the optical fiber rings 3a, 3b.

Abstract: A method for designing a ring communication network is presented. A candidate ring defined by a candidate subset of nodes and a candidate routing is identified. A direction of communication is determined for each of a set of anticipated demands. The cost of operating the ring is calculated based upon the anticipated demands. Finally, the calculated cost is compared to a selected cost threshold to determine if a candidate ring is feasible, wherein the ring communication network comprises the candidate ring.

Abstract: A compensator for thermal or other uncontrollable effects in a liquid-crystal etalon filter. The narrow pass band of the filter is controlled by adjusting the amplitude of an AC drive signal applied to the electrodes on either side of the liquid crystal in the filter. An optical detector detects the intensity of light from a narrow-bandwidth input beam passed by the detector. Electrical circuitry determines the bipolar amplitude of the component of the light intensity that is at twice the frequency of the AC drive signal (the doubled-frequency amplitude) and adjusts the amplitude of the AC drive signal in response to the doubled-frequency amplitude so as to reduce the doubled-frequency amplitude toward zero.
