Abstract: A posture training device is immovably attached to a user's chest. On the exterior of the device, there are three LEDs, an ON/OFF button and a selector button. When the ON/OFF button is first pressed, the device boots to the ON state.

A user presses and holds the central selector button, while standing or sitting in a desired posture position until he feels a vibration. The device locks on to the selected position one second after selector button release. Vibrational negative feedback is provided whenever the user slumps or slouches outside the limits permitted by the chosen sensitivity level. Vibrational positive feedback is provided when correct posture is reestablished. When the ON/OFF button is pressed again, the device shuts OFF.

Abstract: A walking assist device which allays uneasiness felt by a user when a wearable device actively applies torque to a leg. A walking assist device comprises a controller, a headphone and a wearable device attached to left and right legs. The wearable device has a sensor that detects motion of the user's leg and a motor that applies torque to a joint of the user's leg. The controller controls the wearable device such that the joint angle of the user follows a target pattern which represents time-dependent changes of a target joint angle. The controller specifies a change timing at which a time-dependent change of the target joint angle in the target pattern meets a predetermined condition, and informs the user, before the specified change timing, that the change timing is arriving. The uneasiness felt by the user when an actuator actively applies torque to the leg joint is allayed by informing the user of the motion before the actuator performs that motion.

Abstract: The invention provides a body-worn monitor that measures a patient's vital signs (e.g. blood pressure, SpO2, heart rate, respiratory rate, and temperature) while simultaneously characterizing their activity state (e.g. resting, walking, convulsing, falling). The body-worn monitor processes this information to minimize corruption of the vital signs by motion-related artifacts. A software framework generates alarms/alerts based on threshold values that are either preset or determined in real time. The framework additionally includes a series of ‘heuristic’ rules that take the patient's activity state and motion into account, and process the vital signs accordingly. These rules, for example, indicate that a walking patient is likely breathing and has a regular heart rate, even if their motion-corrupted vital signs suggest otherwise.
