20110137603 | Enforcing Worst-Case Behavior During Transmit Channel Analysis - Techniques for analyzing the signal integrity of a channel by enforcing a worst-case behavior during the analysis are presented. Initially a channels response to an input bit sequence, followed by a test bit sequence is simulated. Subsequently, a pulse response is extracted from the simulated channel response. A worst-case pattern bit sequence is then derived from the extracted pulse sequence and the channels response to the worst-case pattern bit sequence is simulated. In further implementations, the channels response to the worst-case pattern bit sequence is displayed for a user. | 06-09-2011 |

20110188562 | Characteristic Response Extraction for Non-Linear Transmit Channels - Techniques for extracting the characteristic response of a non-linear channel are presented. In various implementations of the invention, a channel's characteristic response may be determined by identifying a first input sequence, determining the ones compliment of the first input sequence and then determining the response of the channel to these two input sequences. Subsequently, two input matrices and two response matrices may be generated based upon the two input sequences and their corresponding responses. Given these four matrices, a symmetrical response component may be determined by iteratively solving a system of equations formed from the columns of each matrix. Subsequently, given the symmetric component and these four matrices, an asymmetrical response component may be determined by again iteratively solving the system of equations for the columns of each matrix. | 08-04-2011 |

20090138031 | Thrombectomy catheter with a helical cutter - A thrombectomy catheter including two major members: a cutter of the helically wounded structure and also a cutter of the tubular shape which is located coaxially with the first one. The outside diameter of the helical cutter fits inside diameter of tubular one with a small gap. Thus they cold move independently. Each of them is equipped with the cutting edges on their distal area. Due to this feature the catheter is able to cut off the major portion of the obstacle from a vessel without its fragmentation and safe removing it off the vessel. The catheter is also providing blood perfusion during the surgery as well as provides opportunity for the monitoring of the operation by means of ultrasound, visual etc. devices during the operation. The original flexible design of the helical cutter also prevents the damage of the vessel. | 05-28-2009 |
20100026285 | Material Condition Assessment with Eddy Current Sensors - Eddy current sensors and sensor arrays are used for process quality and material condition assessment of conducting materials. In an embodiment, changes in spatially registered high resolution images taken before and after cold work processing reflect the quality of the process, such as intensity and coverage. These images also permit the suppression or removal of local outlier variations. Anisotropy in a material property, such as magnetic permeability or electrical conductivity, can be intentionally introduced and used to assess material condition resulting from an operation, such as a cold work or heat treatment. The anisotropy is determined by sensors that provide directional property measurements. The sensor directionality arises from constructs that use a linear conducting drive segment to impose the magnetic field in a test material. Maintaining the orientation of this drive segment, and associated sense elements, relative to a material edge provides enhanced sensitivity for crack detection at edges. | 02-04-2010 |
