Lin Wu - Richardson TX, US
Robert Floyd Payne - Allen TX, US
Paul Eric Landman - Allen TX, US
Woo Jin Kim - Dallas TX, US

Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

H03K003/017

US Classification:

327172, 327175, 327100

Abstract:

The present invention facilitates serial communication by performing duty cycle correction. A duty cycle correction component performs duty cycle corrections on a pair of differential sinusoidal signals according to a pair of adjustment signals and, as a result, generates a differential pair of square wave signals. A cross coupled buffer buffers the differential pair of square wave signals and provides the buffered signals to a feedback circuit that measures duty cycles of the signals and generates the pair of adjustment signals accordingly. The buffer can also remove skew from the signals. In a transmitter , the buffered signals are also generally provided to a multiplexer or encoder and in a receiver , the buffered signals are also generally provided to a sampling component.

US Classification:

710 51, 710 52, 370 75, 370315, 370492

Abstract:

A bidirectional repeater and data multiplexer for serial data has A-side I2C port devices A-A coupled to comparators - and pulldowns to ground -. Comparator outputs are coupled responsive to select lines S-S of N:l Select to terminal A of bidirectional control to control pulldown to non-zero low voltage Vp at B-side device B. An inverting comparator coupled to terminal B of bidirectional control responds to input threshold voltage Vt less than low voltage Vp, to prevent data lockup due to data flowback to devices A-A. Output data from comparator is coupled responsive to select lines S-S of 1:N Select to control pulldowns -. This selectively repeats routing of device A-A data to device B. Data from device B is selectively routed to pulldowns of devices A-A.

International Classification:

H04L 7/00

US Classification:

375354

Abstract:

Methods and apparatus to provide clock resynchronization in communication networks are disclosed. An example method of clock resynchronization disclosed herein comprises determining a vote based on adjacent samples occurring within a single bit interval in a sampled data stream, wherein the vote comprises an early vote when the adjacent samples indicate a sampling phase of a sampling clock is early relative to a center position in the bit interval and wherein the vote comprises a late vote when adjacent samples indicate the sampling phase is late relative to the center position, tracking a running difference between a number of early votes and a number of late votes in a plurality of votes corresponding to a plurality of adjacent samples, and adjusting the sampling phase when the running difference reaches a threshold.

International Classification:

G06F 3/00

US Classification:

710316, 710 8

Abstract:

In versions 1. 1a and 1. 2 of the DISPLAYPORT™ standard, capacitors are used between a sourcing circuit and a switch for the auxiliary channel. As a result, these capacitors are generally uncharged when the switch activates the auxiliary channel, which can result in errors. Here, a switch is employed that uses precharge circuits to precharge these capacitors. Thus, errors due to charging of these capacitors can be reduced.

International Classification:

C12Q 1/04
C12Q 1/00

US Classification:

435004000, 435034000

Abstract:

We have developed a high through-put screen capable of isolating inhibitors of polypeptide aggregation, such as Alzheimer's Disease polypeptide Aβ aggregation, or other disease state aggregating proteins, from amidst large libraries of candidate inhibitors. The screen uses a fusion of a polypeptide domain that self-aggregates, such as an Aβ42 domain characteristic of Alzheimer's disease plaques, to a reporter construct, such as Green Fluorescent Protein (GFP) or similar fluorescent protein. In the absence of inhibition, the rapid misfolding and aggregation of Aβ42 causes the entire fusion protein to misfold, thereby preventing fluorescence. Compounds that inhibit Aβ42 aggregation enable GFP to fold into its native structure, and can be identified by the resulting fluorescent signal.

International Classification:

H02S 30/10
F16M 13/02

Abstract:

A mounting assembly comprises a reinforcement channel configured to nest around a first base of a first hat-shaped channel wherein the first hat-shaped channel is configured to nest around a second base of a second hat-shaped channel and the second hat-shaped channel is configured to nest around a load distributing channel. The mounting base, the reinforcement channel, the first hat-shaped channel, the second hat-shaped channel and the load distributing channel are configured to be removable with respect to a fastener along the fastener axis. The fastener is received through coaxial apertures located within the mounting base, the reinforcement channel, the first hat-shaped channel, the second hat-shaped channel and the load distributing channel. The channels are of a certain length that is sufficient to add stiffness to an object being supported by the mounting assembly.
