Abstract: An information handling system comprises a TCP/IP network connecting a hub to a multimedia server and the hub to a data server, and the hub to an IP telephony device that is then coupled to a network device. Data sent from the network device is addressed for transmission to the data server and is transmitted through the IP telephony device to the TCP/IP network. The present invention allows a user, such as a supervisor, to monitor the audio conversations of users on the system and current display information of another station. This can be done between remote systems so that the monitoring individual does not have to be in the same system as the user who is being monitored.

Abstract: The present invention provides a network state machine which supports the three network states of the Home Phone Line Networking Alliance specification version 2.0 (HPNA 2.0) using two network states has been disclosed. When a station is in the V1M2 mode, instead of transmitting this frame in the 10M8 format frame with the gap frame, the frame is transmitted in the 1M8 format frame without any gaps in the frame. With this, the three network state equations of HPNA 2.0 collapses into two equations. With only two network states, the complexity of the network state machine is reduced, and a Physical Layer (PHY) which supports only the two network states may be used.

Abstract: A computer system processor incorporates a special S-latch which may only be set by secure signals. One state of the S-latch sets the processor into a secure mode where it only executes instructions and not commands from an In Circuit Emulator (ICE) unit. A second state of the S-latch sets the processor into a non-secure mode. A non-volatile random access memory (NVRAM) is written with secure data which can only be read by boot block code stored in a BIOS storage device. The boot block code is operable to read the secure data in the NVRAM and set the S-latch to an appropriate security state. If the boot block code cannot set the S-latch, then remaining boot up with BIOS data is stopped. On boot up the boot block code reads the NVRAM and sets the S-latch into the appropriate security state.

Abstract: The N channel field effect transistor (NFET) of the inverting output stage of a LSDL gate is split into a large NFET and a small NFET. The large NFET is coupled to a feedforward pulse so that it is turned ON only when the inverting output is a logic one. When the inverting output is a logic one, another inverting stage turns ON if the dynamic node evaluates to a logic zero. The dynamic node is inverted and coupled to the large NFET on the inverting output stage thus quickly pulling the inverting output to a logic zero. The small NFET is turned ON as a keeper device through the normal logic path. If the inverting data output is a logic zero the feedforward pulse is not generated. By making the largest NFET a pulsed device the other FETs are reduced in size resulting in leakage and switching power savings.

Abstract: A method, system and computer program product for detecting conditions of network instability. An attribute indicative of network instability, e.g., processor and/or co-processor utilization, packet arrival rates, packet peak rates, packet size distribution, packet clustering tendencies, buffer usage patterns, occurrence of peak utilization, out-of-buffer conditions, packet discard rates, may be monitored for a network device, e.g., router. The monitored attribute may be associated with a plurality of labels (variables) where a portion of those labels may be stored in a cache. A hit ratio for the cache storing labels associated with the monitored attribute may be tracked within a period of time based on the number of requested items, i.e., labels, that are currently stored in the cache. A condition of network instability may then be detected based on the hit ratio by determining if the absolute value of the acceleration of the hit ratio exceeds a threshold.

Abstract: An apparatus and method for unaligned cache reads is implemented. Data signals on a system bus are remapped into a cache line wherein a plurality of data values to be read from the cache are output in a group-wise fashion. The remapping defines a grouping of the data values in the cache line. A multiplexer is coupled to each group of storage units containing the data values, wherein a multiplexer input is coupled to each storage unit in the corresponding group. A logic array coupled to each MUX generates a control signal for selecting the data value output from each MUX. The control signal is generated in response to the read address which is decoded by each logic array.

Abstract: A gas-phase method for producing high yields of single-wall carbon nanotubes with high purity and homogeneity is disclosed. The method involves using preformed metal catalyst clusters to initiate and grow single-wall carbon nanotubes. In one embodiment, multi-metallic catalyst precursors are used to facilitate the metal catalyst cluster formation. The catalyst clusters are grown to the desired size before mixing with a carbon-containing feedstock at a temperature and pressure sufficient to initiate and form single-wall carbon nanotubes. The method also involves using small fullerenes and preformed sections of single-wall carbon nanotubes, either derivatized or underivatized, as seed molecules for expediting the growth and increasing the yield of single-wall carbon nanotubes. The multi-metallic catalyst precursors and the seed molecules may be introduced into the reactor by means of a supercritical fluid. In addition the seed molecules may be introduced into the reactor via an aerosol or smoke.

Abstract: A method of performing link stack operations comprises the steps of reading and writing to a link stack. During a write, a location in the link stack pointed to by a current write pointer is selected and a link address associated with an instruction and a current read pointer to the link stack are written into the selected location. After the write operation, the read pointer is updated such that the new read pointer equals the current write pointer and the write pointer is updated. During a read from the link stack, a location in the link stack is selected using a current read pointer. A new read pointer and a link address associated with an instruction are read from the selected read location.

Abstract: A method and system for performing hamming distance comparison. A hamming distance comparator may comprise a plurality of evaluation circuits where each evaluation circuit may be configured to evaluate a bit in a received data packet. Each evaluation circuit may comprise a first and a second capacitor configured to store a true and a complement value of a bit evaluated during a reset state. During an evaluation state, one of the first or second capacitors may be switched if the state of the bit evaluated changed state in a second subsequent received data packet. By switching one of the first or second capacitors, a net change in potential may be provided on a common line coupled to the first and second capacitors. The net change in potential on the common line provided by the evaluation circuits may be used to determine the hamming distance.

Abstract: The present invention relates in general to graphical user interfaces (GUI) in computer display systems, and in particular, to the instrumentation of graphical control for task navigation in a GUI system. The present invention provides a method, apparatus, and processing system for performing a step-by-step procedure using a task oriented interface integrated into a single, intuitive, graphical control/display that further controls the user's ability to navigate through the steps and prevents the user from attempting to revise irreversible steps. The interface display graphically displays how many steps remain to be completed, and how many steps have already been completed. Additionally, it enables the user to deviate from the predefined order of steps and skip optional steps while compelling the user to complete the required steps. The display also differentially displays the completed steps to indicate which steps can be revised and which cannot.

Abstract: Buckyrock is a three-dimensional, solid block material comprising an entangled network of single-wall carbon nanotubes (SWNT), wherein the block comprises greater than 75 wt % SWNT. SWNT buckyrock is mechanically strong, tough and impact resistant. The single-wall carbon nanotubes in buckyrock form are present in a random network of individual single-wall carbon nanotubes, SWNT “ropes” and combinations thereof. The random network of the SWNT or SWNT ropes can be held in place by non-covalent “cross-links” between the nanotubes at nanotube contact points. In one embodiment, SWNT buckyrock is made by forming a SWNT-water slurry, slowly removing water from the slurry which results in a SWNT-water paste, and allowing the paste to dry very slowly, such that the SWNT network of the SWNT-water paste is preserved during solvent evaporation. Buckyrock can be used in applications, such as ballistic protection systems, involving light-weight material with mechanical strength, toughness and impact resistance.

Abstract: A method and system for memory page protection wherein new stack memory load/store instructions are defined for memory management. A corresponding operating system and compiler utilize these new stack memory load/store instructions. Whenever it is desired to have a block of memory used as a stack memory, the stack memory load/store instructions are used. A stack memory attribute is stored in a page table associated with the block of memory. Memory blocks having a stack memory attribute may be read and written into using only stack memory load/store instructions. If a normal load/store is attempted to a memory block having a stack memory attribute a error condition is indicated. Likewise a stack memory load/store to a block of memory not have a stack memory attribute will cause a error condition. Stack memory load/stores meant for one type of stack memory (e.g., program stack attribute) will also cause a fault if the stack load/store is attempted to another type of stack memory (e.g., processor stack).
