Abstract: A traffic manager for a network switch port includes a buffer memory and a buffer manager for writing incoming cells into the buffer memory and for thereafter reading the cells out of the buffer memory and forwarding them. The traffic manager also includes a queue manager for determining an order in which the buffer manager is to forward a set of cells stored in the buffer memory. The queue manager supplies the buffer manager with a sequence of pointers, each pointer referencing a separate cell of the set of cells, with the sequence of pointers being ordered to indicate an order in which the buffer manager is to forward the set of cells. After receiving the pointer sequence, the buffer manager changes the order of pointers in the pointer sequence to optimize a rate at which it can read the cells out of the buffer memory.

Abstract: The present invention relates to apparatus and methods that proactively ensure alignment (parallelism) of the connectors on the circuit board during the solder assembly of the connectors to the circuit board. The apparatus and methods include an alignment fixture that has been specifically designed to ensure parallelism of straddle-mounted connectors during the solder reflow assembly process. The fixture has connector slots and a circuit board slot. The slots help to detect whether the connectors meet the X- and Y-axis alignment requirements after the insertion process (after the connectors have been placed onto the circuit board). That is, if the X- and Y-axis alignment specifications are met, the circuit board with its attached connectors can be completely fitted into the slots of the alignment fixture.

Abstract: A network communications device is arranged to have a fast throughput of data packets. This is achieved by recognising that, in protocols such as Ethernet, the first symbols in a data packet do not carry any data and therefore do not necessarily require to be properly carried through a communications hub. Rather, a known number of symbols are discarded from the start of a packet on receipt and replaced on re-transmission. This discarding reduces the reception delays particularly in bussed-architecture repeaters where bus arbitration must take place for each received packet.

Abstract: A memory device includes an array of memory cells arranged in rows and columns with a portion of the rows of the memory cells being divided into segments. A global bias circuit generates a plurality of first bias currents. Each of a plurality of local bias networks includes a local bias circuit that generates a plurality of second bias currents in response to a corresponding one of the plurality of first bias currents, and includes a plurality of segment bias circuits that each generates a third bias current. Each segment bias circuit is adjacent to a corresponding segment of the memory cells. Each segment bias circuit provides a ground feedback signal to the local bias circuit, which adjusts the second bias current in response to the ground feedback signal.

Abstract: A high voltage generator provides high voltage signals with different regulated voltage levels. A charge pump generates the high voltage, and includes a quadrature phase forward and backward Vt-canceling high-voltage self-biasing charge pump with a powerup-assist diode. A high voltage series regulator generates the high voltage supply levels, and includes slew rate enhancement and trimmable diode regulation. A nested loop regulator eliminates shunt regulation.

Abstract: An operational amplifier comprises multiple stages. A differential input stage that includes an adaptive high voltage differential pair generates up and down output currents in response to up and down input voltages. The differential input stage includes adaptive common input high voltage (HV) bias. An intermediate stage converts the up and down output currents into a first output voltage signal. The intermediate stage includes a folded cascode arrangement. The intermediate stage is biased by fixed voltage bias signals. The intermediate stage also includes unaffected slew rate stability compensation and a combined split stability compensation. An output stage includes a class AB source follower driver that generates a second output voltage signal in response to the first output voltage signal. The output stage is biased with an adaptive push-pull source follower output HV bias. The output stage includes feed-forward slew rate enhancement.

Abstract: The DPIC makes use of the D detected symbols from the output of the Slicer to estimate the precursor ISI which still exists at the input sample of the Slicer. The estimation of the residual ISI value is done by a D-tap Finite Impulse Filter (FIR). This D-tap FIR has the same structure as the DFE or the Echo or NEXT canceller except the values of the coefficients. Since it calculates, A D-symbol delay element is used to keep the DT-delayed sample, from which the corresponding residual precursor ISI computed the D-tap FIR, is removed.

Abstract: A low profile pipe leak repair clamp for sealing a leak in a wide range of pipe sizes includes a flexible, circular metal band lined with a sealing gasket. The clamp a tightening assembly comprising a pair of open and close lugs and a nut and bolt for tightening the band around a leaking pipe. Each lug includes an open slot leading to an inner recess adapted to firmly engage a folded end of the flexible metal band, the recess being of such dimensions as to maintain each folded end in its original shape, thus preventing the metal band from being pulled from the slot upon tightening the clamp. Each lug has an upper jaw and a lower pressure jaw forming the slot and recess. The lower pressure jaw is arcuate at its end and its lower surface chamfered downward to the lower lug surface.

The opening is etched to a substrate location proximate the word line in a self-aligning manner relative to both the bit line and the word line. In another embodiment, capacitor contact openings are formed to elevationally below the bit lines after the bit lines are formed. In a preferred embodiment, capacitor-over-bit line memory arrays are formed.
