The present invention discloses methods and systems for providing very high quality audio playback using all-digital wireless paths from a source to speaker transducers and/or headphones located anywhere within a distance allowed by the FCC. Each speaker has a separate digital amplifier dedicated to each transducer within it (e.g. woofer, tweeter). The present invention also discloses a system that provides a data link capable of sending an all-digital, full-bandwidth, signal from the original digital source material to each separate transducer in the system without using sound degrading lossy data compression. This system is designed to read, broadcast, and reproduce with accurate audio loudspeaker time-alignment (

An isometric exercise system according to the present invention facilitates user interaction with a host computer system and includes at least one effector, at least one sensor coupled to the effector, a platform to accommodate the user and control circuitry including a processor. The platform accommodates a user and includes the effector attached thereto. The sensor measures at least one force applied by a user to the effector, where the applied force effects a strain on or deflects the effector. The processor receives and processes data corresponding to applied force information measured by the sensor for transference to the host computer system in a compatible format and facilitates user interaction with the host computer system via effector manipulation by the user. The host computer system processes the information to update or respond to events within an executing software application (e.g., a game).

A motion platform system includes a support and a motion platform supported by the support and rotatable about a plurality of bearing axes The motion platform is further rotatable with respect to the support about at least one axis that is offset from the plurality of bearing axes. The motion platform may include an intermediate frame supported by the support, where the intermediate frame is rotatable about a first bearing axis with respect to the support. The motion platform may further include an inner frame supported by the intermediate frame, where the inner frame is rotatable about a second bearing axis with respect to the intermediate frame. Rotations of the inner and intermediate frames about the first and second bearing axes facilitate rotation of the inner frame with respect to the support about at least one axis offset from the bearing axes.

An interface device and method for interfacing instruments to a vascular access simulation system serve to interface peripherals in the form of mock or actual medical instruments to the simulation system to enable simulation of medical procedures. The interface device includes a catheter unit assembly for receiving a catheter needle assembly, and a skin traction mechanism to simulate placing skin in traction or manipulating other anatomical sites for performing a medical procedure. The catheter needle assembly and skin traction mechanism are manipulated by a user during a medical procedure. The catheter unit assembly includes a base, a housing, a bearing assembly and a shaft that receives the catheter needle assembly. The bearing assembly enables translation of the catheter needle assembly, and includes bearings that enable the shaft to translate in accordance with manipulation of the catheter needle assembly. The shaft typically includes an encoder to measure translational motion of a needle of the catheter needle assembly, while the interface device further includes encoders to measure manipulation of the catheter needle assembly in various degrees of freedom (e.g., translation, pitch and yaw) and the skin traction mechanism. Alternatively, the shaft may include an additional encoder to measure translational motion of an instrument inserted through the catheter needle assembly. The simulation system receives measurements from the interface device encoders and updates the simulation and display, while providing control signals to the force feedback device to enable application of force feedback to the catheter needle assembly.

A configurable game controller according to the present invention selectively assigns functions within a gaming application to controller input devices. The controller includes input devices, signal sources, a switching device and a switch control unit. The input devices are each coupled to a corresponding signal source that detects or measures manipulation of the corresponding input device and produces a signal indicating the measurement. The signals produced by the signal sources are processed by a signal processor whose inputs are associated in a fixed manner with game functions. The switching device receives information from each signal source and provides the appropriate signals to the signal processor inputs to attain the desired configuration or function assignment received from the user via the switch control unit. In addition, the configurable controller may be utilized with an exercise device to enable exercise and/or controller input devices to control gaming functions.

A computer-based digital wireless audio and video system for consumer audio, home theater and recording studio applications is disclosed. The system distributes synchronized 2-channel stereo and multi-channel home theater video and audio digital signals via wireless broadcast to a closed network including a personal computer, a display, and one or multiple digital active loudspeakers or headphones. Each loudspeaker has a separate digital amplifier dedicated to each transducer within it. The system provides a data link capable of sending an all-digital, full-bandwidth signal from the original digital source material to each separate transducer in the system without using sound degrading lossy data compression. This system is designed to read, broadcast, and reproduce with accurate audio and video channel synchronization in the effort to maintain the integrity of the entire audio and video signal.
