Abstract: Aspects for collision recovery interface support in a home phoneline networking alliance (HPNA) control chip are described. The aspects include providing transmit data path logic to receive and transmit data packets within the HPNA control chip. The transmit data path logic is consolidated to include a transmit state machine that handles interfacing the transmit data path logic to at least two separate collision recovery logic means of the HPNA control chip through a minimal number of generic interface signals.

Abstract: A method, computer program product and system for testing stuck-at-faults. A first register may be loaded with a first value where the first value may be written into each entry in a memory array. A second register may be loaded with a second value. A third register may be loaded with either the second value or a third value. The second and third values are pre-selected to test selector circuits for stuck-at-faults with a pattern where the pattern includes a set of bits to be inputted to selector circuits and a set of bits to be stored in the memory cells. A value stored in the n-most significant bits in both the second and third registers may be predecoded to produce a predecode value. The predecode value may be compared with the value stored in the n-most significant bits in an entry in the memory array to determine a stuck-at-fault.

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 IP telephony device monitors when an amount of data being received over the network falls below a predetermined threshold. If this occurs, the IP telephony device will send a signal to the multimedia server, which will then generate a congestion signal to send to all or selected IP telephony devices in the network to throttle data being received by the IP telephony devices from their respective connected network devices.

Abstract: This invention relates generally to forming an array of single-wall carbon nanotubes (SWNT) and compositions thereof. In one embodiment, a homogeneous population of SWNT molecules is used to produce a substantially two-dimensional array made up of single-walled nanotubes aggregated in substantially parallel orientation to form a monolayer extending in directions substantially perpendicular to the orientation of the individual nanotubes. Using SWNT molecules of the same type and structure provides a homogeneous array. By using different SWNT molecules, either a random or ordered heterogeneous structure can be produced by employing successive reactions after removal of previously masked areas of a substrate. Tn one embodiment, SWNT molecules may be linked to a substrate through a linker moiety such as —S—, —S—(CH2)n,-NH-, SiO3(CH2)3NH- or the like.

Abstract: A hard drive having a protected partition is used in the recovery of a BIOS image for a computer system. An EEPROM is used to store a first BIOS image that is used to boot-up the system and recovery code is used to recover a new BIOS image if the first BIOS image has been corrupted. The new BIOS image is stored in the protected partition of the drive. A recover BIOS command is issued whenever the first BIOS image has been corrupted or a remote or local recover BIOS request is received. When the first BIOS is corrupted, the EEPROM is rewritten with the second BIOS image and the system boots with the rewritten first BIOS image. When a recover BIOS request is received in a data packet sent over a communication link, the data packet is authenticated before the first BIOS image is rewritten.

Abstract: A computer system (e.g., a personal computer (PC)) is loaded with multiple versions of the bootable program (e.g., an operating system (OS)). The boot record for each bootable program version is hashed to produce a digest and the digest is signed using the cryptographic signature engine using the program's private installation key. The resulting signature, along with data indicating the program's name and version, is stored in fields of the non-volatile memory. When the system boots with a version of the program, the active entry is decrypted and the resulting data is compared. If a new version is being booted, then it is determined if the new version is the alternative entry. If so, the active entry is discarded and the alternative version is moved to be the active entry and the system boots with the new version of the program.

Abstract: A system receives AC power from an Uninterruptable Power Supply (UPS) on an AC power cable. The AC power cable couples a primary AC line voltage or a switched secondary AC line voltage depending on the quality of the primary AC line voltage. The UPS has a modulating circuit with a power line carrier protocol that receives a power down signal from the UPS if the primary AC line voltage indicates that the system should power down in a controlled manner or take other power down actions. The modulating circuit generates a modulated power down signal that is coupled to the AC power cable. The system has a corresponding demodulating receiving circuit with the power line carrier protocol that receives the modulated power down signal and regenerates the power down signal. The power down signal is coupled to circuitry in the system that initiates power down sequencing options.

Abstract: Leakage current in logic circuitry is managed by coupling and decoupling the voltage potentials of the power supply from circuitry with large high leakage devices. Driver circuits comprise a low leakage logic path for holding logic states of the output. A high leakage 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 high leakage path that enhances the current drive of a logic state on the output are leakage stress relieved by allowing their drive inputs to collapse after the output logic state has been asserted. The high leakage logic paths employ multiple stages with collapsing logic states that are generated in response to asserted logic states on the output and logic states of the low leakage logic path thus reducing the device sizes needed to control leakage.

This display will have two faces such that the alphanumeric information appears from left to right on both sides of the projected image.

Abstract: A method and system for generating colors efficiently. In one embodiment, a start signal for a primary color subcycle may be received. A primary light source used to drive the primary color may be activated if there is data in the primary color's buffer. The primary light source may be deactivated during the primary color subcycle if there is no data in the primary color's buffer. In another embodiment, a highest amplitude signal for one of a plurality of primary colors may be normalized. A drive light source intensity may be adjusted to a percentage or a maximum intensity where the percentage corresponds to a content of the normalized primary color in a frame. The amplitude of all but the normalized primary color may be adjusted proportionally. In another embodiment, a maximum intensity for a light source intensity may be set to a first value. A maximum pixel intensity for each of a plurality of pixels may be set to a second value.

Abstract: A phase detector employs a modified logic gate in conjunction with a set/reset latch to make a phase detector that generates control outputs for use in increasing and decreasing the delay in a delay circuit in the path of a feedback clock generated by delaying a reference clock. The delay circuit provides a controllable delay from less than to greater than one clock cycle of the reference clock. The phase detector generates an up control (UP) signal for increasing delay when the feedback clock leads the reference clock and a down control (DN) signal for decreasing delay when the feedback clock lags the reference clock. The UP signal and DN signal are updated each clock cycle when the leading clock edge makes a transition.

Abstract: A high speed signal transmission system employs differential receivers for receiving data signals transmitted over circuit transmission lines. One input each receiver is coupled to the output of a transmission line and to a termination network. The termination network generates a termination voltage and a source impedance that is matched to the characteristic impedance of the transmission line. The other input of the receiver is coupled to a reference voltage. The termination voltage may be adjusted by programming signals while keeping the source impedance constant and matched to the transmission line. A test mode may be employed where known data signals are transmitted and received and the termination voltage is adjusted while monitoring the states of the received signals on the output of the receivers. In this manner, the system may be optimized or tested for noise margin in an actual operation environment without resorting to probing methods.

More generally, a distributed processing technique and associated method are disclosed for analytical processes that require access to a massive database.

Abstract: The present invention is directed toward methods for incorporating low work function metals and salts of such metals into carbon nanotubes for use as field emitting materials. The present invention is also directed toward field emission devices, and associated components, comprising treated carbon nanotubes that have, incorporated into them, low work function metals and/or metal salts, and methods for making same. The treatments of the carbon nanotubes with the low work function metals and/or metal salts serve to improve their field emission properties relative to untreated carbon nanotubes when employed as a cathode material in field emission devices.

Abstract: A system and method for remotely measuring the temperature of an object using microwave radiometry that may be used in hostile environments. A single pole-single throw reflective PIN diode switch is operable in a PASS mode and a BLOCK mode. In the PASS mode, the switch passes the power received from the object to a low-noise block converter (“LNB”) for amplification. In the BLOCK mode, the switch blocks the object power and reflects the load noise power of an ambient temperature load to the LNB. A detector diode detects the amplified power output during both the BLOCK and PASS mode and the AC signal from the detector is converted to an output signal proportional to the difference in the noise powers detected in the PASS and BLOCK modes.

Abstract: This invention relates generally to cutting single-wall carbon nanotubes (SWNT). In one embodiment, the present invention provides for preparations of homogemeous populations of short carbon nanotube molecules by cutting and annealing (reclosing) the nanotube pieces followed by fractionation. The cutting and annealing processes may be carried out on a purified nanotube bucky paper, on felts prior to purification of nanotubes or on any material that contains single-wall nanotubes. In one embodiment, oxidative etching with concentrated nitric acid is employed to cut SWNTs into shorter lengths. The annealed nanotubes may be disbursed in an aqueous detergent solution or an organic solvent for the fractionation. Closed tubes can also be derivatized to facilitate fractionation, for example, by adding solubilizing moieties to the end caps.

Abstract: This invention relates generally to a method for producing self-assembled objects comprising single-wall carbon nanotubes (SWNTs) and compositions thereof. In one embodiment, the present invention involves a three-dimensional structure of derivatized single-wall nanotube molecules that spontaneously form. It includes several component molecule having multiple derivatives brought together to assemble into the three-dimensional structure. In another embodiment, objects may be obtained by bonding functionally-specific agents (FSAs) groups of nanotubes into geometric structures. The bond selectivity of FSAs allow selected nanotubes of a particular size or kind to assemble together and inhibit the assembling of unselected nanotubes that may also be present.

Abstract: An area is established by positioning a string of boundary objects that are reflective to a range of ultrasonic frequencies. Tracking objects may be placed inside the area which also are reflective to the range of ultrasonic frequencies. An array of transducers insonify the area and the reflected signals are received by each transducer, digitized and stored as digital data. The digital data is read out in time reverse order and time reversal signals are generated that are coupled to each corresponding transducer. The time reversed signals focus energy on the reflective sources. The reflected signals resulting from the time reversed signals are analyzed to generate a reference signature indicating relative locations of boundary and tracking objects. The time reversed signals are sent intervals to generate new signatures which are compared to the reference signature to determine if tracking objects have been moved outside the area.
