The present invention defines a new protocol for communicating with an offload engine that provides Transmission Control Protocol (“TCP”) termination over a Fibre Channel (“FC”) fabric. The offload engine terminates all protocols up to and including TCP and performs the processing associated with those layers. The offload protocol guarantees delivery and is encapsulated within FCP-formatted frames. Thus, the TCP streams are reliably passed to the host. Additionally, using this scheme, the offload engine can provide parsing of the TCP stream to further assist the host. The present invention also provides network devices (and components thereof) that are configured to perform the foregoing methods. The invention further defines how network attached storage (“NAS”) protocol data units (“PDUs”) are parsed and delivered. |

Engine start control apparatus, engine start control method, and motor vehicle equipped with engine start control apparatus
In a motor vehicle with idle stop function, upon satisfaction of preset engine restart conditions (step S205), automatic engine restart control refers to a preset map representing a variation in amount of fuel Q1, which is to be initially injected into a cylinder Cyin stopping in an intake stroke, against the piston stop position Pin of the cylinder Cyin, and specifies the amount of fuel Q1 corresponding to the detected piston stop position Pin of the cylinder Cyin (step S220). The automatic engine restart control then controls an injector to inject the specified amount of fuel Q1 into an intake port of the cylinder Cyin (step S230). Under the condition that the piston stop position Pin of the cylinder Cyin suggests low gas intake performance, the increased amount of fuel Q1 is injected into the intake port of the cylinder Cyin. This arrangement desirably reduces a misfire rate at the timing of first combustion and thereby improves the startability of an engine. When the amount of fuel Q1 specified at step S220 is equal to zero, the cylinder Cyin is not subject to the first combustion. Such control desirably prevents poor emission. |

Disclosed is a method of generating a detection signal for detecting energy in a spread-spectrum signal, comprising: de-spreading the spread-spectrum signal by applying a predetermined spreading code to obtain a sequence of de-spread signal symbols (202A-202D); accumulating a number of said signal symbols to obtain a single detection signal. The accumulation includes: obtaining a first and a second subset of said de-spread signal symbols, wherein the symbols of the first subset have values that are known to the receiver or at least known to be the same for all symbols of the first subset, and wherein the symbols of the second subset have unknown values; coherently accumulating the symbols of the first subset to obtain a first partial detection signal (203A, 203B, 203C); non-coherently accumulating the symbols of the second subset to obtain a second partial detection signal (204A, 204B, 204C); and combining the first and second partial detection signals to obtain the single detection signal (208). |

Interferometric scanning method(s) and apparatus for measuring test optics having aspherical surfaces including those with large departures from spherical. A reference wavefront is generated from a known origin along a scanning axis.

The light that travels through the cells in the sample will experience a difference in the optical path length compared to the surrounding media and the wave front that emerges from the 10 cells will thus be phase shifted. This distortion can be detected in the digital hologram, which is reconstructed from the interference pattern detected by a digital sensor (17), such as a CCD or a CMOS, as phase differences or phase shifts and thereby creating a digital hologram. The 15 phase shift of each element of the hologram is then used for analyzing the characteristics of the cells in the sample. |

Method and apparatus for using multiple relative reflectance measurements to determine properties of a sample using vacuum ultra violet wavelengths
A method and apparatus is disclosed for measuring properties of an unknown sample. A reflectometer and one or more reference pieces is provided. A set of data is collected from the unknown sample and a combination of the reference pieces. A combination of the sample and reference piece data independent of incident intensity is used to determine a property of the unknown sample without calibrating incident reflectometer intensity. The method and apparatus disclosed can measure properties of thin films or scattering structures on semiconductor work pieces. In one embodiment the reflectometer utilizes vacuum ultraviolet (VUV) wavelength reflectometry. Multiple relative reflectance measurements are used to overcome effects of the inevitable contamination buildup that occurs when using optical systems in the VUV region. While advantageous for VUV wavelengths, the method described herein is generally applicable to any wavelength range, and is advantageous in situations where stable reference samples are not available. |

According to the present invention, a polarized image is captured, a variation in its light intensity is approximated with a sinusoidal function, and then the object is spatially divided into a specular reflection area (S-area) and a diffuse reflection area (D-area) in Step S402 of dividing a reflection area. Information about the object's refractive index is entered in Step S405, thereby obtaining surface normals by mutually different techniques in Steps S406 and S407, respectively. Finally, in Steps S410 and S411, the two normals are matched to each other in the vicinity of the boundary between the S- and D-areas. |

Systems and methods for remote monitoring of contaminants in fluids
A system and method of monitoring contaminant particles in pipelines. The system can include a probe for extending into a pipeline, and sampling fluid in the pipeline to ensure that a representative amount of contaminants within the pipeline can subsequently be measured. An analyzer receives the sampled fluid from the probe, illuminates the sampled fluid with a light source, and collects scattered light from any contaminant particles in the illuminated sampled fluid. A detector receives the scattered light from the analyzer, and converts the scattered light into an electrical signal that is proportional to the contaminant particles size. A processor receives the electrical signal from the detector, converts the electrical signal into digital data pertaining to the contaminant particles, and transmits the digital data on an Ethernet connection, or wireless signal to a communication network for distribution to at least one digital data processor for display and evaluation. |

Defect inspection method and apparatus with a threshold value determination
Scattered light from the surface of a sample subjected to the same process as a process for an inspection object is observed, a defect is detected from an intensity of scattered light, and a position of the detected defect and an intensity of scattered light caused by the detected defect are acquired.
