摘要： Detecting a boundary between training sequences in a transmission is an important operation. In many communications systems, there are no special boundaries or markers to denote the end of one sequence and the beginning of another. Correlation has been a commonly used technique to detect sequences and a fall in the correlation can be used to indicate such boundaries, but classical correlation can be slow and a significant portion of the new sequence is received prior to the boundary being detected. A method and apparatus is presented that allows rapid detection of the boundary and only a small amount of the new sequence needs to be received prior to the detection of the boundary. Additionally, the method and apparatus can be used to detect the presence of a transmission on the communications medium.

摘要： In a sheet stacking and unloading system in which sheets are stacked on a stacking tray which is then moved from its sheet stacking position to an unloading position for removing the sheet stack from the stacking tray, and the stacking tray has a sheet stacking surface partially interrupted by at least one handhold area for allowing manual lifting access underneath a portion of a stack, there is automatically inserted into the handhold area at least one supplemental sheet stack supporting member to provide supplemental sheet stacking support, preventing the sheets from sagging in those areas, which supplemental sheet stack supporting member is automatically removed from the handhold area when the stacking tray is moved to its unloading position.

摘要： A method of forming a dual gate fin-type field effect transistor (FinFET) structure patterns silicon fins over an insulator and patterns a gate conductor at an angle to the fins. The gate conductor is formed laterally adjacent to and over center portions of the fins. The gate conductor is planarized such that the gate conductor is separated into distinct gate conductor portions that are separated by the fins. These gate conductor portions include front gates and back gates. The front gates and the back gates alternate along the structure, such that each fin has a front gate on one side and a back gate on the opposite side. Then front gate wiring is formed to the front gates and back gate wiring is formed to the back gates.

摘要： The invention is directed to a tensioner assembly for providing tensile force from a floating vessel at the surface of the ocean to the blowout preventer stack, or production tree, which is connected to the wellhead at the sea floor. The tensioner assembly compensates for vessel motion induced by wave action and heave and maintains a variable tension to the riser string alleviating the potential for compression and thus buckling or failure of the riser string. The tensioner assembly of the present invention includes a cylinder, a stop tube disposed with the cylinder, and a ram slidably engaged within the stop tube. The tensioner assembly also includes at least one gas, or air, transfer tube to create a pressurized air over hydraulic fluid arrangement to provide tensile force to the tensioner assembly.

摘要： Devices, systems, and methods controllably cool blood vessels and other body lumens. The blood vessel will often be treated for atherosclerotic or other diseases by inflating a balloon so as to engage the surrounding luminal wall. Controlled cooling of the balloon effected by a change in phase of a cryogenic fluid within the balloon typically a change from a liquid phase to a gas phase can be provided with a controlled, gradual inflation of the balloon. A single control system can be used for any of a variety of alternative selectable balloon catheters having significantly differing cooling fluid flow characteristics.

摘要： A multistage amplifier is disclosed for amplifying light over a wavelength band. A first and second span of amplifying fiber are optically coupled and a gain flattening filter (GFF) in-line with one of two spans of amplifying fiber is provided for attenuating certain wavelengths of amplified light. A first gain spectral response of the first and second spans of amplifying fiber including the GFF are measured over the wavelength band, and the shape of a ripple that oscillates as a function of wavelength in the form of a plurality of peaks or maxima and valleys in the form of minima occur at a plurality of different wavelengths, each different wavelength corresponding to a different channel. A second filter is provided finishing or compensating filter having a second spectral response that has a second plurality of peaks in the form of maxima and valleys in the form of minima is provided. The second filter is designed so that the second spectral response is absent at least 50% of four most predominant peaks or valleys at channels where peaks or valleys, respectively, were present in the first spectral response. The maximum ripple amplitude in the second spectral response is less than a maximum ripple amplitude in the first gain spectral response. This arrangement lessens unwanted effects of systematic error occurring when filters having similar ripple responses with wavelength are cascaded.

摘要： A semiconductor substrate includes a pair of trenches filled with a dielectric material. Dopant introduced into the mesa between the trenches is limited from diffusing laterally when the substrate is subjected to thermal processing. Therefore, semiconductor devices can be spaced more closely together on the substrate, and the packing density of the devices can be increased. Also trench constrained doped region diffuse faster and deeper than unconstrained diffusions, thereby reducing the time and temperature needed to complete a desired depth diffusion. The technique may be used for semiconductor devices such as bipolar transistors as well as isolation regions that electrically isolate the devices from each other. In one group of embodiments, a buried layer is formed at an interface between an epitaxial layer and a substrate, at a location generally below the dopant in the mesa. When the substrate is subjected to thermal processing, the buried layer diffuses upward, the dopant in the mesa diffuses downward until the two dopants merge to form an isolation region or a sinker extending downward from the surface of the epitaxial layer to the buried layer. In another embodiment, dopant is implanted between dielectrically filled trenches at a high energy up to several MeV, then diffused, combining the benefits of deep implantation and trenched constrained diffusion to achive deep diffusions with a minimal thermal budget.
