Abstract: A method and an apparatus are disclosed for scoring the quality of sleep experienced by a subject wearing the apparatus for a specified period. This sleep monitoring apparatus includes a motion sensor that quantifies the temporal variation in the subject's motion, an analog to digital converter to sample the sensor data, a microprocessor with embedded programmable memory to store control and processing firmware, a memory device for data storage, a display means, and a switch for staring and resetting the device. The firmware for this apparatus: (i) directs the microprocessor to sample sensor output at a prescribed time interval and to temporarily store this data in the memory device, (ii) directs the microprocessor to analyze the temporarily stored data to compute a sleep score based on the magnitude of movements recorded during the monitoring period, and (iii) controls the operation of the display means.

Abstract: A method and a device for counting the number of sleep disordered breathing events experienced by a subject within a specified time period.

Abstract: The present invention provides a method and a device for counting the number of sleep disordered breathing events experienced by a subject within a specified time period.

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.

Abstract: A method and apparatus for accurate and convenient feedback to a user concerning activity level performance. Features of the invention include visual and audible outputs indicating a current level of activity. Another feature includes varying the rate of an audible tone output to reflect an actual and current activity level. In one embodiment an audible outputs is provided when a user's activity level reaches a desired minimum threshold within a given period of time. These features provide immediate and reliable feedback to a user for improved maintenance of at least a desired level of activity.
