System and method for patient medical care initiation based on physiological monitoring data with the aid of a digital computer
Individuals who suffer from certain kinds of medical conditions, particularly conditions that only sporadically exhibit measurable symptoms, can feel helpless in their attempts to secure access to medical care because, at least in part, they are left to the mercy of their condition to present symptoms at the right time to allow diagnosis and treatment. Providing these individuals with ambulatory extended-wear health monitors that record ECG and physiology, preferably available over-the-counter and without health insurance preauthorization, is a first step towards addressing their needs. In addition, these individuals need a way to gain entry into the health care system once a medically-actionable medical condition has been identified. Here, the ECG and physiology is downloaded and evaluated post-monitoring against medical diagnostic criteria. Medical specialists are pre-identified and paired up with key diagnostic findings, such that an individual whose monitoring data indicates a medical concern will be automatically referred and treated. |

Systems and methods for improving cell-edge receiver performance
Systems and methods for providing improved cell-edge antenna performance are disclosed. The system can use various signal quality indicators (SQIs) for each user equipment (UE) on a particular wireless base station (WBS) or network.
