Abstract: A method for communicating a Physical Layer (PHY) mean square error (MSE) to an upper layer device driver includes: receiving a frame by the PHY; computing a MSE for the frame by the PHY; sending the MSE and the frame to a Media Access Control (MAC); inserting the MSE into a frame status frame (FSF) associated with the frame by the MAC; and sending the frame and the FSF to the upper layer driver software. With access to the PHY MSE, the upper layer driver software can compute the average mean square error (AMSE) and determine if a change in the payload encoding (PE), or data transmission rate, should be negotiated. In this manner, the data transmission rate can be optimized while maintaining a low error rate.

Abstract: A buffer, logic circuit, and data processing system employing fast turn-off drive circuitry for reducing leakage. Leakage current in logic circuitry is managed by coupling and decoupling the voltage potentials applied to large, high-leakage devices. Circuitry includes a low leakage logic path for holding logic states of an output after turning off high-leakage devices. A fast turn-off logic path in parallel with the low leakage logic path is used to assert each logic state in the forward direction from input to output. The large output device in each fast turn-off path is relieved of leakage stress by asserting logic states at driver inputs that cause the driver to turn OFF after the output logic state has been asserted.

Abstract: A mechanism for automatically generating code, in particular high level source code for remotely accessing functionality running in a remote process is provided. Given a specified set of functionality, which may be defined via an interface, for providing functionality to a local process, the mechanism generates, in source code form, software for remotely accessing the functionality by an application running in another process, that is, for accessing the functionality by an application running a second process. The code may be generated at build time but before the actual build of a software product implementing the functionality.

Abstract: A method, system and computer program product for detecting the dissemination of malicious programs. The degree of randomness in the Internet Protocol (IP) destination addresses of received IP packets to be forwarded to an external network may be detected by performing a hash function on the IP destination addresses thereby generating one or more different hash values. If a high number of different hash values were generated for a small number of IP packets examined, then random IP destination addresses may be detected. By detecting random destination IP addresses, the dissemination of a malicious program, e.g., virus, worm program, may be detected.

Abstract: An integrated circuit design has circuit macros made up of device cells. The cells are characterized by determining the leakage current dependency on various process, environmental and voltage parameters. When circuit macros are designed their leakage power is calculated using this data and multi-dimensional models for power and temperature distribution. Circuit macros are identified as timing-critical and timing-noncritical macros. Statistical methods are used to determine the average leakage sensitivities for the specific circuit macros designed. The designer uses the sensitivity data to determine how to redesign selected circuit macros to reduce leakage power. Reducing leakage power in these selected circuits may be used to reduce overall IC power or the improved power margins may be used in timing-critical circuits to increase performance while keeping power dissipation unchanged.

Abstract: A method and computer program product for bypassing the initial sign-on of an underlying operating system with single sign-on capability. In one embodiment, a method comprises the step of providing an application framework which logs on a user with a first level of access in the underlying operating system thereby bypassing the initial sign-on screen of the underlying operating system. The method further comprises entering a logon input, e.g., userID and password, on a generated application framework sign-on screen by the user. The method further comprises comparing the logon input with an application framework security database to determine the level of access. If the user is only entitled to the first level of access, then the user is restricted to a first level of access. If the user is entitled to another level of access, then a switch user program may be executed to switch the level of access to a second level of access, i.e., change in the assortment and/or number of applications.

Abstract: A method and system for maintaining synchronization in a home network is disclosed. The home network includes a host ethernet media access controller and an HPNA chip, where control frame and data frame pairs are transferred between the host ethernet media access controller (MAC) and the HPNA chip. The method and system include sending a null frame from the host ethernet MAC to the HPNA chip prior to the data frame, and recognizing the null frame on the HPNA chip as an indication that a next received frame will be the data frame, thereby maintaining synchronization between the control frame and the data frame pairs.

Abstract: Circuitry used to de-skew data channels coupling parallel data signals over a communication link employs SOI circuitry that is subject to generating pulse distortion due to the history effect modifying threshold voltages. To substantially eliminate the pulse distortion, data signals are XOR with a repeating scramble data pattern that generates scrambled data with a minimum average ratio of logic ones to logic zeros logic zeros to logic ones. The scrambled data is sent over the communication link and de-skewed in the SOI circuitry with little or no pulse distortion. The scramble data pattern is again generated at the receiver side of the communication link after a delay time to synchronize the logic states of the scramble data pattern that generated the scrambled data with the scrambled data at the receiver side. The delayed scrambled data pattern is again XOR'ed with the scrambled data to recover the data signal.

Abstract: An LSDL circuit replaces the normal clock control of the pre-charge device for the dynamic node with a control signal that is logic zero whenever the circuit is in an active mode and is a logic one when the circuit is in standby mode. The pre-charge device holds the dynamic node at a pre-charged logic one state independent of the clock. During the logic one evaluate time of the clock, the logic tree determines the asserted state of the dynamic node. During the evaluate time, the asserted state is latched by the static LSDL section. The dynamic node then re-charges to the pre-charge state. Since the pre-charge device is not de-gated during the evaluate time, the dynamic node cannot be inadvertently discharged by noise causing an error. Likewise, since the clock does not couple to the pre-charge device a load is removed from the clock tree lowering clock power.

Abstract: A method and system for reducing memory accesses by inserting qualifiers in control blocks. In one embodiment, a system comprises a processor configured to process frames of data. The processor may comprise a plurality of buffers configured to store frames of data where each frame of data may be associated with a frame control block. Each frame control block associated with a frame of data may be associated with one or more buffer control blocks. Each control block, e.g., frame control block, buffer control block, may comprise one or more qualifier fields that comprise information unrelated to the current control block. Instead, qualifiers may comprise information related to an another control block. The last frame control block in a queue as well as the last buffer control block associated with a frame control block may comprise fields with no information thereby reducing memory accesses to access information in those fields.

Abstract: A method for functionalizing the wall of single-wall or multi-wall carbon nanotubes involves the use of acyl peroxides to generate carbon-centered free radicals. The method allows for the chemical attachment of a variety of functional groups to the wall or end cap of carbon nanotubes through covalent carbon bonds without destroying the wall or endcap structure of the nanotube. Carbon-centered radicals generated from acyl peroxides can have terminal functional groups that provide sites for further reaction with other compounds. Organic groups with terminal carboxylic acid functionality can be converted to an acyl chloride and further reacted with an amine to form an amide or with a diamine to form an amide with terminal amine. The reactive functional groups attached to the nanotubes provide improved solvent dispersibility and provide reaction sites for monomers for incorporation in polymer structures. The nanotubes can also be functionalized by generating free radicals from organic sulfoxides.

Abstract: Activation of printed or dispensed carbon nanotube (CNT) film using a particle-blasting technique, also referred to as sandblasting or bead blasting. The process works by sending particles of material at high enough velocity such that when the particles hit the surface, some of the material at the surface is removed. The surface of the printed CNT film is slowly eroded away by the particles from the particle gun. The CNT fibers may be embedded in several layers of the printed layer, so they may not be removed easily.
