Abstract:
A method and apparatus detects a ground fault on a span-powered telecommunication wireline within a plurality of span-powered wireline segments, to respective ones of which DSL-Cs are coupled, so that a ground fault may be detected when power is delivered by the DSL-C over a respective wireline segment to a respective downstream functional RT. A respective DSL-C measures a first voltage across a first sense resistor representative of current flowing in a first portion of its wireline segment to the RT, and also measures a second voltage across a second sense resistor representative of current flowing in a second portion of the wireline segment from the RT. In response to a difference in the first and second voltages an output representative of a ground fault in that wireline segment is generated.
Abstract:
A system for processing presentation instruments that includes a presentation instrument reservoir, a presentation instrument reader, a distribution stock holder, a distribution stock reader, two or more motor systems for advancing distribution stock and presentation instruments, and attaching the presentation instruments to the distribution stock when codes printed on the instruments and stock match each other. In some cases, the motor systems can interface to an interface controller via a serial interface, and the interface controller can be coupled to a process control computer via an Ethernet connection. In some cases, distribution stock is blank and has no readable code, in which case the blank stock is automatically advanced to a reject bin without interrupting the operation of system.
Abstract:
The present technique relates to a method and apparatus for managing voltage buses. In a memory device, such as SRAM or DRAM, a periphery voltage bus may supply voltage to periphery circuitry and an array voltage bus may supply voltage to array circuitry. A bridge circuit may be utilized to isolate the buses from each other and couple the buses together, depending on the control signals are received by the bridge circuit. As such, the bridge circuit enhances the operation of the memory device by reducing duplicative circuits and equalizing the voltage that are applied to the buses. In addition, the bridge circuit isolates the buses from each other to protect sensitive circuitry in the array and periphery circuitry from noise on the other bus.
Abstract:
A development tool enables a device database to be created, managed, and deployed to a device as part of the a device project. The device database may have an installation property which provides logic for installing the device database at the device. Additionally, stored procedures and triggers may be registered with the device database. The registered stored procedures and triggers may be embedded in the device database and deployed to the device along with the device database.
Abstract:
A redundancy address decoder for a memory having at least one bank of memory segmented into a plurality of memory blocks. The redundancy address decoder includes a plurality of redundancy comparison circuitry coupled to a respective programmable element block storing addresses that are mapped to redundant memory of a memory plane. The redundancy address decoder further includes redundancy driver select logic coupled to each of the redundancy comparison circuitry to activate a selected one of the redundancy comparison circuitry for comparing a portion of a memory address corresponding to a memory location with the programmed addresses of the respective programmable element blocks, which leads to power reduction for column accesses to the memory device. The selection of the redundancy driver is based on the memory bank in which the memory location is located.

The present invention is directed to an aqueous superabsorbent polymer paste comprising from about 1 to about 5 wt % of superabsorbent particles and from about 95 to about 99 wt % of an aqueous water-soluble solution having from about 0.5 to about 5%, preferably from about 1 to about 3% solid level. The present invention is also directed to a coated substrate comprising a substrate material and an aqueous superabsorbent polymer paste comprising a blend of i) from about 1 to about 5 wt % of superabsorbent particles and ii) from about 95 to about 99 wt % of an aqueous water-soluble solution. The present invention is also directed to a method for reducing the loss of circulation fluids into flow passages of a subterranean formation during well drilling, completion or work over operations, by using the aqueous superabsorbent polymer paste of the present invention.
Abstract:
An insertion system for collating sheets of printed material for insertion into an envelope is disclosed. The insertion system includes an insertion machine, application software and an operating system. Included in the application software is a first function and a second function, where the first function performs tracking for each packet and the second function controls operation of the insertion machine. Each packet includes a plurality of pieces of printed material that may ultimately be sealed in an envelope. The operating system runs the application software at any given instant and executes the first and second functions.

Abstract:
An adapter that buffers received symbols and automatically determines and corrects for skew between lanes is disclosed. In one embodiment, the adapter is a part of a network that includes a first and second devices coupled together by a communications link having multiple independent serial lanes. The first device Initiates communication by repeatedly transmitting a training sequence that includes a start symbol for each lane. An adapter in the second device includes a set of buffers each configured to receive the symbols conveyed by a corresponding serial lane. The buffers are coupled to a reconstruction circuit that removes one “symbol groups” at a time from the buffers. A symbol group is made up of one symbol from each buffer. The reconstruction circuit removes symbol groups until a start symbol is detected. If the start symbol is not detected in all buffers, output from buffers having start symbols is temporarily suspended.
Abstract:
A composite stent/graft tubular prosthesis includes an inner PTFE tubular structure, an outer PTFE tubular structure assembled about the inner PTFE tubular structure, and a circumferentially distensible stent interposed between the inner and outer PTFE tubular structures. The outer tubular body is a non-continuous body formed of polytetrafluoroethylene components, providing axial and circumferential compliance to said prosthesis. The outer tubular body completely overlies the distensible stent.
