A novel and useful apparatus for and method of multiple input multiple output (MIMO) detection for use in MIMO based communication systems. The mechanism of the invention performs a simplified tree search utilizing a single stage expansion of the most likely first symbol candidates, in the case of a 2×2 MIMO system. The invention also provides a refinement mechanism that is operative to significantly improve the soft information (i.e. log likelihood ratio) of the list of candidates. To improve the soft information, the mechanism applies one or more refinements rounds to generate additional candidates for both first and second detected symbols.

Road height values for a road network area are generated based on locations of junctions and stacking orders of roads in junctions in which at least one road passes over another road. A cost function can be optimized to obtain height values for each road of each junction. The cost function can be constrained such that roads of the grade separated crossings satisfy the stacking order designated for the roads and to have a minimum distance between roads having consecutive stacking order values. The obtained height values can be used for rendering a three-dimensional map of a part of the road network area.

An endoluminal stent composed of a plurality of first structural elements arrayed to form the circumference of the stent and extending along the longitudinal axis of the stent, and a plurality of second structural elements that interconnect adjacent pairs of first structural elements. The plurality of first structural elements have either a linear shape or a generally sinusoidal configuration with either a regular or irregular periodicity or regions of regular and regions of irregular periodicity between the peaks and troughs of the pattern, with the peaks and troughs projecting from the first structural elements in the circumferential axis. The plurality of second structural elements are generally linear or sinusoidal-shaped members which interconnect an apex of a peak of one of the plurality of first structural elements with an apex of a valley of a second and adjacent one of the plurality of first structural elements. Each of the plurality of second structural elements are generally oriented parallel to the circumferential axis of the stent.

An adjustable gas block for a gas operated firearm offering a means to adjust a volume of gas directed to the host rifle's operating system. The adjustable gas block provides two positions of adjustment that are selectable based on the presence of a pressure increasing device being mounted on the firearm. A first position provides an optimal volume of gas into the gas operating system absent a back pressure increasing device. A second position usable in the presence of a back pressure increasing device causing venting of a portion of the volume of gas into a secondary chamber prior to release into the atmosphere. The amount of gas received by the operating system due to venting is reduced to a volume that is substantially equal to the volume of gas that would be received by the operating system absent a back pressure increasing device.

A method of metering a fluid, pollutant-reducing medium, in particular an aqueous urea solution, into a motor vehicle exhaust system is proposed, in which the fluid medium is delivered to a nozzle module, in particular a nozzle or a valve, and introduced into the exhaust system by the nozzle module. A transport system arranged upstream of the nozzle module is activated with pulse-width modulation. The method and the associated metering system ensure that, in particular, a reducing agent is arranged or metered precisely and in a robust manner relative to degrees of coldness, with the use of few components.

A prosthetic valve assembly for use in replacing a deficient native valve comprises a replacement valve supported on an expandable valve support. If desired, one or more anchors may be used. The valve support, which entirely supports the valve annulus, valve leaflets, and valve commissure points, is configured to be collapsible for transluminal delivery and expandable to contact the anatomical annulus of the native valve when the assembly is properly positioned. Portions of the valve support may expand to a preset diameter to maintain coaptivity of the replacement valve and to prevent occlusion of the coronary ostia. A radial restraint, comprising a wire, thread or cuff, may be used to ensure expansion does not exceed the preset diameter.
