A system and method for controlling the speed of operation of sexual stimulation devices from videos of sexual activity using a less computationally intensive method of estimating movement speed from a video. In an embodiment, the system and method involve estimating movement in a video using pixel-by-pixel color change over time, calculating a rate of color change in the video, estimating a speed of movement in the video from the rate of color change, and applying an algorithm to convert the estimated speed of movement in the video to a speed of operation of a sexual stimulation device.

An assist device includes a first harness, a second harness, a belt body, an actuator and a controller. The controller is configured to perform operation control of the actuator. The controller is configured to, upon operation of the actuator being started in a state in which the first harness and the second harness is fitted to the user, perform winding of the belt body with a first winding force, and is configured to, upon the winding of the belt body being completed, change the winding force of the actuator to a second winding force that is smaller than the first winding force.

A system and method for voice-based control of sexual stimulation devices. In some configurations, the system and method involve receiving voice data, analyzing the voice data to detect spoken commands, and generating control signals based on the commands. In some configurations, the system and method involve receiving voice data, analyzing the voice data for non-speech vocalizations, detecting voice stress patterns, and generating control signals based on the detected patterns. In some configurations, the analyses of the voice data are performed by machine learning algorithms which may be trained on associations between speech and non-speech vocalizations of a user while the user engages in one or more voice-based training tasks, associating speech and non-speech vocalizations with controls of the sexual stimulation device. In some configurations, machine learning algorithms are used to make the associations. In some configurations, data from other biometric sensors is included in the associations.

A system and method for adaptive speech and biofeedback control of sexual stimulation devices. In an embodiment, the system and method involve receiving audio from a microphone, processing the audio through an automated speech detection engine to detect speech within the audio, matching the speech to a control command for a sexual stimulation device, generating a control signal for the sexual stimulation device based on the control command, receiving biometric data from a biometric sensor, and adjusting the control signals based on the biometric data before outputting the adjusted control signal for use in operating the sexual stimulation device. In some embodiments, the adjustment to the control signal is made automatically by a machine learning algorithm using the command and biometric data as inputs.

A cushion promotes healthy blood flow within the body when the patient is sitting/lying down. A pressure controlling support automatically balances user weight, detects application of user weight, or otherwise detects when the user is at-risk for pressure sores. Pressure is dynamically redistributed by inflation/deflation of individual bladders, rebalancing user support. The cushion prevents the user from applying their weight to impede their blood flow at an at-risk location or from cramping their musculature. The cushion also massages the user's musculature, by moving a pressure difference about selected bladders, promoting blood flow and reducing seating fatigue. The cushion detects changes in pressure at each bladder, to detect/predict user fidgeting/movement and adjust pressure in response thereto, to support the user's new position.

A knee rehabilitation active motion machine (KRAM) and method of use. The KRAM provides key benefits for users after undergoing knee replacement or other surgeries. Studies have indicated that pedaling and balance exercises provide better recovery for total knee replacement patients. The adjustable features of a pedaling unit and a moving assembly allow the user to use the KRAM through the entirety of their rehabilitation process. For post-surgery rehabilitation, users will be able to adjust the KRAM parameters to limit their desired flexion and extension due to stiffness or soreness. As rehabilitation progresses, users can electronically increase the flexion and extension angles they can achieve, all the way to a full range of motion of approximately 135 degrees maximum flexion and full extension of approximately 20 to 0 degrees.
