Abstract: A computing system generates an extended reality environment for an end user. The extended reality environment includes a plurality of tasks and a plurality of goals to be achieved by the end user. The computing system receives input data from an extended reality system associated with the end user. The computing system updates a progress of the end user through the plurality of tasks and the plurality of goals based on the input data. The computing system receives a voice command from the end user. The voice command corresponds to a statement uttered by the end user within the extended reality environment. The computing system processes the voice command to generate a response to the voice command. The computing system causes the response to appear within the extended reality environment as an audible, visual or haptic feedback response to the voice command.

Abstract: A computing system helps a user in an extended reality (XR) learning experience achieve mastery through personalized, programmable and conversational coaching. One aspect is that the XR learning experience may consist of a plurality of tasks associated with the user. A second aspect is that the XR learning experience can define different types of conversational interventions triggered by the computing system at various times. A third aspect is that some tasks or interventions can make use of a conversational assistant. A fourth aspect is that as the user is going through the XR learning experience, the system determines which, if any, interventions can be triggered based on the user's state.

Abstract: The present invention is a method and apparatus for non-invasive, real-time monitoring of the autonomic nervous systems. The present invention allows for monitoring of the autonomic nervous system using spectral analysis of both heart rate and respiratory signals. A preferred embodiment uses short-time Fourier transform (STFT) with a novel modified Bartlett windowing scheme in real-time so that the dynamic interactions between the sympathetic and parasympathetic divisions of the autonomic nervous system can be independently monitored. In addition, a preferred embodiment of the present invention uses the same techniques to monitor other biological or physiological data, including continuous blood pressure.

Abstract: A method and apparatus for non-invasive, real-time monitoring of the autonomic nervous systems using non-stationary spectral analysis of both heart rate and respiratory signals. Continuous wavelet transformation is used in real-time so that the dynamic interactions between the sympathetic and parasympathetic divisions of the autonomic nervous system can be independently monitored in the frequency domain. The method in accordance with the present invention allows spectral analysis, formerly limited to the study of stationary data, to be applied to time-varying biological data such as heart rate variability and respiratory activity. In addition, the same techniques are used to monitor other biological or physiological data, including blood pressure.

Abstract: A teleconferencing system uses video conferencing between a nurse station and a patient station to deliver medical care. The patient station is programmed to contain customized instructions concerning medications, procedures, or visitations that were placed there by the nurse. The customized audio, video and text information transforms the patient station into a highly personalized information source which can be reviewed by the patient when the unit is off line. Medical procedures and medications are also programmed into the patient station by the nurse to remind the patient of all scheduled events, including visitations. A record of medical compliance is stored in the patient station, which record is uploaded to the nurse station and compared to the original event schedule. In such manner, the patient station is an intelligent personal medical assistant, programmed by the nurse to provide customized reminders and information necessary for the efficient management of the patient's illness.

Abstract: A process for controlling a gimballed motion base system substantially duplicating operator perceptions in a simulated vehicle. Such vehicles may include but not be limited to, aircraft, automobiles, boats, roller coasters, bob sleds, and futuristic space vehicles. The process includes: a subprocess accounting for an effect of yaw on a motion base arm, a full-G bias function and a limited-G bias function, a low-G bias function, improved computation of pitch and roll gimbal commands to negate artifacts, a negative-G process, allowing various yaw gimbal positions, allowing various cockpit orientations, and a yaw gimbal control process.A perceptual model based on empirically observed human response data predicts perceived pitch, roll, and yaw, and accounts for the fact that a Gy component of linear acceleration affects both roll and yaw perception.

Abstract: A arterial blood velocity-to-volume flow rate converter, including a pair of function generators a computer, and a multiplier, is incorporated within a system to objectively measure by non-invasive means the blood volume flow rate to the head of an occupant in a rapidly accelerating vehicle, and take corrective measures to stabilize the vehicle when that flow falls below a preselected lower limit for a predetermined length of time. A conventional ultrasonic Doppler velocimeter determines the blood velocity, subsequently feeding a representative signal to pressure function generator. The output therefrom is then fed to a cross-sectional area signal generator which determines the time-varying area of the artery, a signal representing such being fed to the multiplier along with the velocity signal to compute the flow.
