Abstract: The present invention provides a novel rate adaptation algorithm and QoS-aware MAC scheduling system and method that either maximizes user satisfaction or maximizes spectrum utilization while maintaining user satisfaction by trading off the spectral resource allocations of connections for the application-level QoS based on the user-specific requirements. An adaptive scheduler is presented that incorporates user specific QoS requirements in the spectral allocation of resources.

Abstract: An integrated vectorcardiogram (VCG) device having 3 pairs of electrodes placed in three orthogonal directions with the capability to continuously measure the electrical activity of the heart. All of the electrode pairs may be contained within a single miniaturized housing thereby eliminating the need for cumbersome wires required with current 12-lead ECG systems, while providing the same amount and quality of information as the 12-lead ECG system. The integrated VCG device also includes a communications function to allow the data collected by the electrodes to be transmitted wirelessly to a remote device, such as a pacemaker, to control its function or to a remote monitoring station for continuous real-time patient monitoring.
