Methods for analyzing system operator coupling susceptibility are described herein. In one embodiment, an open loop frequency response can be compared to a related over-steer point. An over-steer point can be the condition where, as operator gain is increased for an open loop system, the corresponding closed loop gain at a corresponding resonance peak increases by at least approximately the same amount as the increase in operator gain or at least approximately a selected larger amount than the increase in operator gain. In other embodiments, an open loop frequency response can be compared to a critical gain rate. The critical gain rate can be the rate of change of open loop gain per open loop phase angle of the corresponding open loop system response at an over-steer point that is associated with a zero decibel closed loop gain.

The invention provides assay methods and reagents useful for evaluating the level of enzyme activities within living cells. Enzyme activity levels within living cells, such as caspases and Serine proteases, can be key determinates in assessing; 1) the apoptotic state of a cell, 2) the presence of tumor (cancer) cells, 3) the predictive efficacy of a chemotherapeutic treatment regimen using a particular therapeutic agent or process, 4) the probability of graft rejection or acceptance, identification of the up or down regulation relationships of serine proteases and caspases within living cell systems, provides a rapid, yet finely tuned mechanism for predicting the current and future state of these cell populations, and 5) the disease state status of a cell.

In a specific embodiment, a system for providing video is disclosed, the system having a system bus, which in one embodiment is an Advanced Graphics Port (AGP) bus. The system bus is connected to a data bridge, which is connected to a second and third AGP bus. Each of the AGP busses are connected to graphics processors. The bridge routes data requests from one graphics processor to the second graphics processor without accessing the system AGP bus based upon a memory mapping information stored in a routing table or a register set. In another aspect of the present invention, the bridge responds to initialization requests using attributes that may vary depending on the specific mode of operation. Another aspect of the present invention allows for conversion between various AGP protocol portions.

An improved etch sequence and an improved integration scheme of plasma doping in the fabrication of a DRAM integrated circuit device are described. Semiconductor device structures are provided in and on a substrate wherein the substrate is divided into an array area and a periphery area. The semiconductor device structures are covered with a dielectric layer. The dielectric layer is concurrently etched through in the array area to form bit line contact openings and in the periphery area to form substrate contact openings. Doped regions are formed in the substrate exposed within the bit line contact openings and the substrate contact openings using a plasma doping process. Next, the dielectric layer is etched through to form a gate contact opening. Thereafter, the bit line contact openings, the substrate contact openings, and the gate contact opening are filled with a conducting layer to complete forming contacts in the fabrication of a DRAM integrated circuit.

The present invention teaches a modular telephone jack "system" capable of voice and data applications, which may be relatively flush-mounted within a conventional electrical box or to a surface and which is characterized by the absence of conventional screw terminal technology. A lacing strain relief system facilitates connections in terminal clips which face forward and which are accessible from the front of the system for testing and repair through a snap-off face or cover plate, and facilitates relatively rapid installation and easy access for testing, troubleshooting and wiring. The system may be equipped with combinations of duplex modular jacks of similar outer configurations, such as four, six and eight-conductor versions. The system includes its own "universal" surface-mounting housing of box, where needed.

A method and apparatus for accessing a non-volatile memory cell. In some embodiments, a memory block provides a plurality of memory cells arranged into rows and columns. A read circuit is configured to read a selected row of the memory block by concurrently applying a control voltage to each memory cell along the selected row and, for each column, using a respective local sense amplifier and a column sense amplifier to successively differentiate a voltage across the associated memory cell in said column to output a programmed content of the row.
