Abstract: Methods and systems for combining ablation therapy with navigation of the ablation device. An ablation system may be configured for use with one of two methods to prevent loss of navigation signals during ablation energy delivery. In the first method, ablation energy signals are filtered from the navigation signal. In the second method, the delivery of ablation energy is sequenced with the delivery of navigation energy such that ablation energy and navigation energy are not delivered at the same time and navigation signals received by the system are time-division multiplexed to reconstruct the navigation signals and determine a location of the device within the patient.

Abstract: A leg stabilization or performance system for a skier or snowboarder that absorbs part of the pressure on a user's legs and drives the resistance force down to user's boots, acting like a shock absorber is disclosed. This function also allows the skis or snowboard to keep closer contact with the snow, giving the skier/snowboarder more control through the turns. The performance system includes removably fixable leg straps, upper and lower adjustable leg shafts or portions, a resistance assembly with a shock absorber and a variable resistance adjuster, a boot attachment, and an activator switch. The configuration of the system allows a user to set the system to various levels of resistance.

Abstract: A system for composing alphanumeric characters and/or decorative designs from modules containing line segments. The line segments within each module are to be provided with means to make each line segment differentially visible, for example light-emitting diodes, liquid crystal displays, etc. The arrangement of line segments within the modules is the means whereby a variety of typefaces previously unobtainable in illuminated lettering or signage is now made available through the use of the present invention. Two module types, each with a different arrangement of line segments within, are herein specified.

Abstract: A system of composing alphanumeric characters and/or decorative designs from modules containing line segments. There are eight different module types (I-VIII), each different module type containing a differently shaped or positioned line segment. Most characters are formed by placing six modules in an array of three high by two wide; those of the module types which are needed to create the desired character are used in the array. Some character require an array only three modules high, while others require an array of three modules high by three modules wide. This embodiment has application in the fields of signage, tiling, games, and educational toys.In another embodiment a system for composing alphanumeric characters and/or decorative designs from compound modules is provided.
