In geology and physical geography, a plateau ( /pləˈtoʊ/, /plæˈtoʊ/, or /ˈplætoʊ/; French: [pla.to]; plural plateaus or plateaux), also called a high plain or a tableland, is an area of a highland, usually consisting of relatively flat terrain, that is raised significantly above the surrounding area, often with one or more sides with steep slopes. Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, and erosion by water and glaciers. Plateaus are classified according to their surrounding environment as intermontane, piedmont, or continental.
Ablation system and method of use
InactiveUS6989010B2Simple systemImproving impedanceDiagnosticsSurgical instruments for heatingEngineeringPlateau
A system and method for creating lesions and assessing their completeness or transmurality. Assessment of transmurality of a lesion is accomplished by monitoring the impedance of the tissue to be ablated. Rather than attempting to detect a desired drop or a desired increase impedance, completeness of a lesion is detected in response to the measured impedance remaining at a stable level for a desired period of time, referred to as an impedance plateau. The mechanism for determining transmurality of lesions adjacent individual electrodes or pairs may be used to deactivate individual electrodes or electrode pairs, when the lesions in tissue adjacent these individual electrodes or electrode pairs are complete, to create an essentially uniform lesion along the line of electrodes or electrode pairs, regardless of differences in tissue thickness adjacent the individual electrodes or electrode pairs.

The invention provides a method of correcting numerous bone abnormalities including bone tumors and cysts, avascular necrosis of the femoral head, tibial plateau fractures and compression fractures of the spine. The abnormality may be corrected by first accessing and boring into the damaged tissue or bone and reaming out the damaged and / or diseased area using any of the presently accepted procedures or the damaged area may be prepared by expanding a bag within the damaged bone to compact cancellous bone. After removal and / or compaction of the damaged tissue the bone must be stabilized.

ActiveUS7591792B2Improves signal couplingImproves resulting measurementElectrotherapyAntenna supports/mountingsMeasurement pointEngineering
Tissue sensors house one or more sensor elements. Each element has a housing mounted substrate and a superstrate with a planar antenna between. A transitional periphery (TP) of a superstrate outer surface interconnects a base to a plateau. At least some of the TP has a generally smooth transition. Plural elements are spaced by the housing. Alternately, the superstrate TP is flat, the housing extends to the outer superstrate surface and a shield surrounds the element. The housing is flush with or recessed below the superstrate and defines a TP between the housing and superstrate. A method converts a reference signal to complex form; plots it in a complex plane as a reference point (RP); converts a measurement signal to complex form; plots it in the complex plane as a measurement point (MP); determine a complex distance between the MP and the RP; and compares complex distance to a threshold.

Described herein are power conservation systems and methods that reduce power consumption for an electronics device including a liquid crystal display (LCD). The LCD includes a backlight that offers multiple luminance levels, where each level consumes a different amount of power. The systems and methods alter video information while the backlight remains at a backlight luminance level. The alteration reduces luminance for the video information to produce new video information that can be presented at a lower backlight luminance level. Change to the lower backlight luminance level may then occur without significantly affecting aggregate luminance of the new video information, as perceived by a user. The LCD and electronics device consume less power at the lower luminance level.
