  • Publication number: 20120280732
    Abstract: Described herein are an apparatus, system, and method for compensating voltage swing and duty cycle of a signal on an input-output (I/O) pad of a processor by adjusting the voltage swing and duty cycle of the signal. The apparatus comprises a driver to transmit a signal on an I/O pad, the signal on the I/O pad having a voltage swing and a duty cycle; and an adjustment unit, coupled to the driver, to receive the signal from the I/O pad transmitted by the driver and to generate voltage swing and duty cycle control signals for adjusting the voltage swing and duty cycle of the signal on the I/O pad respectively. Described herein is also an analog-to-digital (A2D) converter for measuring and/or calibrating various signal attributes including current, voltage, and time.

  • Patent number: 8142538
    Abstract: A filter element in the form of a nonwoven self-supporting filtration web having rows of folded or corrugated spaced-apart pleats, the web containing continuous thermoplastic fibers a majority of which are aligned at 90°±20° with respect to the row direction. The filter element can be made by forming rows of pleats in such a nonwoven web and cutting the web to a desired size and shape. The filter elements can provide improved mechanical and filtration properties and can exhibit reduced susceptibility to pleat deformation and the loss of space between pleats.

  • Patent number: 7957428
    Abstract: Embodiments of the invention provide an algorithm for dividing a link into one or more reduced-width links. For one embodiment of the invention, a multiplexing scheme is employed to effect a bit transmission order required by a particular cyclic redundancy check. The multiplexed output bits are then swizzled on-chip to reduce on-board routing congestion.

  • Patent number: 7844767
    Abstract: A technique is described by which two link agents with ports coupled together using a point-to-point interconnect in a system exchange their link width support capabilities and negotiate a link width that is mutually agreeable. The interconnect between each pair of agents comprises a pair of uni-directional links having multiple electrical wires, or lanes, where one link is used by a first agent to transmit data to a second agent and another link is used by the second agent to transmit data to the first agent.

  • Patent number: 7804890
    Abstract: A discussion of improving integrated device deterministic response to test vectors. For example, limiting the transmission delay for an integrated device's response within known bounds by synchronizing an initialization training sequence to a reset deassertion. Specifically, the proposal facilitates response determinism from the DUT by synchronizing training sequences and subsequently synchronizing flit transmission to reset assertion as sampled by reference clock.

  • Patent number: 7765698
    Abstract: A method of making an electret article, from a polymeric article that has a zeta potential of greater than or less than ?7.5 millivolts. The article is charged by contacting it with an aqueous liquid that has a pH and conductivity as follows: (i) if the article has a zeta potential of ?7.5 mV or less, then the contacting liquid has pH greater than 7 and a conductivity of 5 to 9,000 microSiemens per centimeter; and (ii) if the article has a zeta potential of greater than ?7.5 mV, then the contacting liquid has a pH of 7 or less and a conductivity of 5 to 5,500 microSiemens per centimeter. An electret article made in this manner can provide improved electret performance, particularly in electret filtration articles.

  • Publication number: 20080227169
    Abstract: A method for immobilizing an amino-containing material to a substrate is described. The method involves providing a tethering compound with two reactive groups: a substrate reactive group and a fluoroalkoxycarbonyl group. The method further involves preparing a substrate-attached tethering group by reacting the substrate reactive group of the tethering compound with a complementary functional group on the surface of a substrate. The substrate-attached tethering group has a fluoroalkoxycarbonyl group that can be reacted with an amino-containing material to form an immobilization group that connects the amino-containing material to the substrate.
