Abstract: Method and apparatus are disclosed for thermally destroying a layer of an organ such as the mucosal layer of the gall bladder. The apparatus includes a catheter (100) having an elongated member (103) having a plurality of lumens therein. At the distal end of the elongated member is an electrode (104) for emitting radiofrequency current to the mucosal layer (101). Also at the distal end is a capacitive balloon electrode (106) surrounding the current-emitting electrode for containing an electrolyte solution (107) and for distributing the radiofrequency current to the mucosal layer (101). The balloon electrode is expanded with the electrolyte solution to conform and make contact with the mucosal layer. The electrolyte solution has a resistivity significantly less than the resistivity of the gall bladder wall, as well as the gall bladder bile, to cause a concentrated power deposition in the mucosal layer. The distal end of the catheter is endoscopically inserted into the body (114) of the gall bladder (102) by a retrograde route through the duodenum (117), common bile duct (118) and cystic duct (119). While the balloon electrode is being expanded, the bile present in the gall bladder is drained through one of the lumens in the elongated member. The apparatus also includes a radiofrequency generator (112) for supplying radiofrequency current to the current-emitting electrode. The current-emitting electrode is energized for a period of time to cause the mucosal layer to be heated for a predetermined period of time to thermally coagulate the mucosal layer of the gall bladder and cystic duct. A dispersive electrode (120) is positioned on the skin of the patient's body to facilitate a complete circuit back to the generator without causing trauma to the patient.

Abstract: A computing system includes a processor (101), a system memory (104) containing data utilized by the processor (101) and two cache memories. Each cache memory is connected directly to the processor (101). A first cache memory (103) is connected to the processor (101) and to the system memory (104). The first cache memory (103) contains a subset of data in the system memory (104). A second cache memory (102) is also connected to the processor (101). The second cache memory (102) contains a subset of data in the first cache memory (103). Data integrity in the system memory (104) is maintained using the first cache memory (103) only. Whenever the processor (101) writes data, the processor (101) writes data both to the first cache memory (103) and to the second cache memory (102). Whenever the processor (101) reads data, the processor (101) attempts to read data from the second cache memory (102). If there is a miss at the second cache memory (102), the processor (101) attempts to read data from the first cache memory (103). If there is a miss at the first cache memory (103), the data is retrieved from the system memory (104) and placed in the first cache memory (103). The processor (101) then reads the data from the first cache memory (103). Generally, when the processor (101) reads data from the first cache memory (103), the read data is written into the second cache memory (102).

Abstract: Methods and apparatus for sending link state information through a network of nodes interconnected by links. Link state packets (LSPs) are fragmented, and the fragments are sent individually through the network. The network routers may update their link state databases and perform routing without having to receive and reassemble all of the fragments. When the state of a link changes, only an amended version of the fragment affected by the change is transmitted. In another aspect, the invention features methods and apparatus for transmitting LSP sequence number information through the network. First, the link state packets being stored by a node are ordered alphabetically according to their source node. Next, a range of this order is selected and placed in a summary packet indicating the boundaries of the selected range and, for each link state packet in the selected range, the source and sequence number of the stored link state packet.

Abstract: Modern subscriber terminals, e.g. featurephone, MultiTel and modern ancillary devices, normally offer a whole range of facilities to make them easier to use. To simplify the communication process, these devices usually contain a digital memory for data, in particular for telephone numbers, names, addresses etc., where the contents of the memory can either be shown visually on a display or can be output in audible form. To enable the data transmitted via the telecommunication network to be stored automatically, even during the temporary absence of the subscriber, and to be read out in simple fashion by the called subscriber, a buffer memory is disposed in the subscriber terminal. A control device compares the telephone number in the buffer memory with those in the memory and, if the telephone numbers coincide, the data allocated to this telephone number are read out from the memory and are also stored in the buffer memory. By pressing a button, the subscriber can retrieve in succession the data stored in the buffer memory, e.g. telephone numbers, and use them for automatic call set-up. The new subscriber terminal enables the representation of any temporarily stored messages in surprisingly simple fashion and can be used in differently configured communication networks for switched connections. <IMAGE>

Abstract: Direct Electrostatic Printer (10) including a combination toner charging and delivery system. The combination toner charging and delivery system (12) serves to convey well charged toner to an area adjacent an apertured printhead (14) through which toner particles are propelled in image configuration. The system is provided with an annular channel (35) in a generally cylindrical member (34) through which toner laden air moves under pressure. During movement uncharged toner particles collide with a triboactive surface of the channel (35) due to centrifugal force and become charged. The other surface delineating the channel carries a bias electrode thereon. The electrostatic field created by the bias prevents toner from colliding with the triboactive surface once it has reached a predetermined charge/mass ratio.

Abstract: A user inquiry facility and method are described for use in a computerised data processing system which provides for monitoring of conversations or information transmission between a user of the data processing system, during the execution of the user's program, and a communication partner (which could include a database or other facility) associated with the data processing system. Task progress tracing information is selected from the conversations and stored. The stored information is updated to keep it current with the progress of the task of the user's program. An instruction is provided by the facility or method which, when activated, by the user selects task progress tracing information from the stored information and after formatting it for readability is transmitted to the user's display or terminal. The inquiry facility is independent of the successful operation of the user's program so that it can feedback information to the user about any failure in the program or in any communication paths used for the conversations.

Abstract: A fault-tolerant storage device array using a copyback cache storage unit for temporary storage. When a Write occurs to the RAID system, the data is immediately written to the first available location in the copyback cache storage unit. Upon completion of the Write to the copyback cache storage unit, the host CPU is immediately informed that the Write was successful. Thereafter, further storage unit accesses by the CPU can continue without waiting for an error-correction block update for the data just written. In a first embodiment of the invention, during idle time for relevant storage units of the storage system, an error-correction block is computed for each "pending" data block on the copyback cache storage unit, and the data block and corresponding error-correction block are copied to their proper location in the RAID system. The copyback cache storage unit in effect stores "peak load" Write data and then completes the actual Write operations to the RAID system during relatively quiescent periods of I/O accesses by the CPU. In a second embodiment of the invention, after Write data is logged to the copyback cache storage unit, normal Read-Modify-Write operation by the RAID system controller continues in overlapped fashion with other CPU I/O accesses using Write data in the controller's buffer memory. Performance is enhanced because the CPU can continue processing as soon as the simple Write operation to the copyback cache storage unit completes, thus eliminating the delay caused by a normal Read-Modify-Write RAID system. In this embodiment, the copyback cache storage unit acts more as a running "log" of Write data.
