Abstract: The present invention provides a method and apparatus for diagnosing of the medical condition of a fully ambulatory subject who exhibits temporal variations in various physiological parameters as a result of the subject's medical condition. The method comprises the steps of (1) locating a separate, self-contained, recording unit on a plurality of selected measurement sites of the subject, (2) using these units to collect sensor output data, (3) sampling this sensor output data at prescribed time intervals, (4) time stamping and storing this sampled data in recording, (5) transferring this data via a smart input/output interface device to an external computer, and (6) using the external computer with appropriate application software to analyze and diagnose the medical condition of the subject. A system of recording units is disclosed for an embodiment of the present invention directed at diagnosing subjects exhibiting sleep disorders.

Abstract: The present invention provides a method and a device for evaluating a fully ambulatory subject for sleep apnea.

Abstract: The present invention provides apparatus and methods for monitoring and recording the position and extent of motion of the body of a human or a lower animal. In a preferred embodiment of the invention, it comprises: (1) a three-dimensional-position monitoring, mercury sensor, (2) a programmable control unit that receives as input the output from the sensor and has the capability to sufficiently interpret said input so as to determine the position and related movements with respect to gravity of the measurement site at which said sensor is located on its user's body, (3) a storage device, operable by said control unit, that stores time-stamped, data regarding the user's body position and related movements, and (4) an interface device that has the capability of transferring the stored data to an external computer.
