An orientation and position tracking system and method in three-dimensional space and over a period of time utilizing multiple inertial and other sensors for determining motion parameters to measure orientation and position of a moveable object. The sensors, for example vibrational and angular velocity sensors, generate signals characterizing the motion of the moveable object. The information is received by a data acquisition system and processed by a microcontroller. The data is then transmitted to an external data reception system (locally based or a global network), preferably via wireless communication. The information can then be displayed and presented to the user through a variety of means including audio, visual, and tactile. According to various embodiments, the present invention provides for a motion tracking apparatus and method for implementation in motion systems including systems to teach motion to a group and for body motion capture and analysis systems.

A method of cutting material for use in an implantable medical device employs a plotted laser cutting system. The laser cutting system is computer controlled and includes a laser combined with a motion system. The laser precisely cuts segments out of source material according to a predetermined pattern as designated by the computer. The segments are used in constructing implantable medical devices. The cutting energy of the laser is selected so that the cut edges of the segments are melted to discourage delamination or fraying, but communication of thermal energy into the segment beyond the edge is minimized to avoid damaging the segment adjacent the edge.

An in-vivo imaging device incorporating a double field of view imaging system, having a wide field of view with moderate magnification, and a narrow field of view with substantially higher magnification, axially superimposed thereon. A single imaging array is used for both fields of view. At least some of the optical elements are shared between both of the two different field of view imaging systems. The imaging elements for the high magnification system, being of substantially smaller diameters than those of the low magnification system, are disposed coaxially with the imaging elements of the low magnification system, and can thus use the same imaging array without the need for deflection mirrors, beam combiners or motion systems. Their location on the axis of the low magnification system means that a small part of the imaging plane, around its central axis, is blocked out by the high magnification components.

Lost motion systems and methods for providing engine valves with variable valve actuation for engine valve events are disclosed. The system may include a master piston hydraulically linked to a slave piston, and a dedicated cam operatively connected to the master piston. The slave piston may be disposed substantially perpendicular to the master piston in a common housing. The slave piston is adapted to actuate one or more engine valves. The slave piston may incorporate an optional valve seating assembly into its upper end. A trigger valve may be operatively connected to the master-slave hydraulic circuit to selectively release and add hydraulic fluid to the circuit.

An exercise system includes a user input arrangement; a rotatable member that rotates in response to an input force applied by a user on the user input arrangement; a power sensing arrangement that senses power applied to the rotatable member due to the input force applied by the user; and a variable resistance arrangement interconnected with the power sensing arrangement and with the user input arrangement. The resistance arrangement applies resistance to rotation of the rotatable member, and is variable in response to the power sensing arrangement to vary the resistance applied to the rotatable member. The variable resistance arrangement may be a brake that interacts with the rotatable member to resist rotation of the rotatable member, and to thereby resist the input force applied by the user. The variable resistance arrangement includes a controller for controlling the brake in response to the power sensing arrangement.

An alternative embodiment includes a spring winder drum pulley combination.

An exercise system includes a simulation system simulating real-world terrain based on environmental and other real-world conditions. Using topographical or other data, an actual location can be simulated. The exercise system may include a speed, incline or other mechanisms that can be adjusted based on changes in simulated slope, and by amounts simulating actual air resistance due to movement, wind, or both. The simulated speed of the person, as well as speed and direction of simulated wind, are used to determine a simulated air speed. Based on the simulated air speed, the simulation system determines the simulated air resistance that would affect the person under real-world conditions, and changes reflective of the simulated air resistance are made to operating parameters of the exercise system. Simulation may occur by causing the user of the exercise system to expend about the same effort as if performing the exercise in the real-world conditions.
