Abstract: The present disclosure teaches systems, devices, and methods to monitor the correct positioning of a positive airway pressure (PAP) mask. In the system, a PAP mask monitor is configured to capture sound from a PAP device over a first period of time; capture sound from a patient breathing over the first period of time; determine a difference between the PAP device sound and the patient breathing sound over the first period of time; and identify, based on a fast Fourier transform (FFT) analysis a selected frequency that can distinguish the patient's breathing from other noise. The PAP mask monitor is further configured to assert a dislodged mask alert signal if a breathing event is not detected during a determined apnea time window; and communicate an alarm signal to a smart wearable device that will awaken the patient so that the mask can be re-positioned properly.

Abstract: The present disclosure teaches systems, devices, and methods to detect sleep apnea. A method, for example, includes affixing a sleep apnea detection device to a patient. The sleep apnea detection device has a processor, at least one memory, at least one micro-electromechanical system (MEMs) device, at least one transceiver, and at least one power source to power the sleep apnea detection device. Data that indicates the patient's breathing is collected with the at least one MEMs device, and based on the collected data, at least one of the patient's inhalations and the patient exhalations is determined. It is also determined when the patient fails to inhale over a determined first period of time. Based on a number of times the patient fails to inhale, an Apnea Hypopnea Index (AHI) score is calculated, and if the AHI score crosses a selected threshold, it is determined that the patient has sleep apnea.

Abstract: The present disclosure relates to conducting testing on a remote client computer by a server computer. The remote client computer is connected to the server computer through a network which allows either the remote client computer or server computer to initiate a testing session with the other. Programs resident on the remote client computer and server computer initiate the session. A graphics test tool application program is resident on the server computer. The graphics test tool application program includes a set of instructions and data used to communication to a set of instructions and data in the remote client computer. Communication in particular is performed through a communication channel which further allows graphics tests to be sent from the graphics test tool application program to the remote client computer. The graphics tests may be timed as to how long they take to be sent to the remote client computer.
