Abstract: A network accelerator for TCP/IP includes programmable logic for performing network protocol processing at network signaling rates. The programmable logic is configured in a parallel pipelined architecture controlled by state machines and implements processing for predictable patterns of the majority of transmissions. Incoming packets are compared with patterns corresponding to classes of transmissions which are stored in a content addressable memory, and are simultaneously stored in a dual port, dual bank application memory. The patterns are used to determine sessions to which an incoming IP datagram belongs, and data packets stored in the application memory are processed by the programmable logic. Processing of packet headers is performed in parallel and during memory transfers without the necessity of conventional store and forward techniques resulting in a substantial reduction in latency. Packets which constitute exceptions or which have checksum or other errors are processed in software.

Abstract: Novel traffic management schemes of a telecommunications network using the concept of virtual links is disclosed. As an example, if a switch connects via a high bandwidth link to an access mux that drives lower bandwidth links. The mux is a potential congestion point in the downstream direction (from high to low bandwidth links) because traffic can arrive at a greater rate over the high bandwidth link than it can exit through the lower bandwidth link. If all of the traffic destined for a particular low bandwidth link can be organized into a unique virtual link. This virtual link can be scheduled at a maximum rate not exceeding the bandwidth of the low bandwidth link, thus preventing the mux from ever becoming a congestion point. Therefore, the amount of mux buffering can be reduced to a very small amount (for jitter absorption). One advantage of this scheme in this example is potentially large cost reductions in the high volume access mux at the lesser expense of a more complex low volume switch.

Abstract: Each of two end sections and one middle section of the present basket form is formed with a centrally and axially disposed passageway and with a pair of diametrically opposing passageways spaced radially outwardly from the central passageway. All of the passageways in one of the sections are simultaneously alignable with corresponding passageways in the other sections. The central passageways are adapted to receive a mounting member. Each of the radially outwardly disposed passageways are adapted to receive a bolt, and a wing nut is tightened onto an outwardly projecting threaded end of each bolt to hold the separable sections of the form in alignment with one another. The middle section of the form may be removed and the two end sections held in alignment with one another to accommodate a shallower basket.

Abstract: An ink jet printer with wiper blade and vacuum canopy cleaning mechanism, and method of assembling the printer. The printer comprises a print head having a surface thereon surrounding a plurality of ink ejection orifices. The orifices are in communication with respective ones of a plurality of ink channels formed in the print head. A vacuum hood capable of sealingly surrounding at least one of the orifices has a passageway therethrough capable of being disposed in communication with the orifice for vacuuming contaminant from the ink channel by way of the orifice. A solvent delivering wiper is connected to the hood and has an areaway therethrough alignable with the surface. The areaway delivers a liquid solvent to the surface to flush contaminant from the surface. Contaminant residing on the surface is entrained in the solvent while the wiper flushes contaminant from the surface. Wicking channels disposed on the bevel edge of the wiper aid in the removal of cleaning liquid and contaminant.

Abstract: A method of applying a wear-resistant hardface material (alloy) to a portion of a turbine blade, typically a wear surface on a shrouded turbine blade. A thin foil of brazing alloy (which in the preferred embodiment is a nickel-based alloy) is placed over said wear surface, and a hardface alloy of a greater than desired thickness (which in the preferred embodiment is a cobalt-based alloy) is placed thereover, thereby sandwiching the foil therebetween. The wear surface, foil, and hardface material are heated for a period sufficient to melt the foil and cause bonding of the hardface alloy to the wear surface. The hardface material is thereafter machined to bring the wear surface to design tolerances. A turbine blade, and a method of rebuilding a portion of a turbine blade, are also disclosed.

Abstract: A DRAM architecture configures memory cells into a predetermined number of arrays. Each array has its own row decoders and sense amplifiers. A data path circuit containing local drivers and data read and write lines is associated with each of the arrays in a first direction. The respective connections between the array and data path circuit utilize IO lines that are considerably shorter than the IO lines used in prior art architectures. Using this unique arrangement of data path circuits and memory arrays as a building block, a DRAM architecture of increased capacity can be constructed by simply placing additional data paths and memory arrays on to the semiconductor device in a second direction orthogonal to the first direction.

Abstract: A method for forming a planarized thin film dielectric film on a surface of a common circuit base upon which one or more integrated circuits are to be attached. The common circuit base includes raised features formed over its surface such that the raised features define a trench area between them. The method includes the steps of forming a first layer of the dielectric film over the common circuit base and over the raised features and the trench, then patterning the newly formed layer to remove portions of the layer formed over the raised features and expose the raised features. After the layer is patterned, formation of the dielectric film is completed by forming a second layer of the dielectric film over the patterned first layer.
