An apparatus for assisting a rescuer in performing chest compressions during CPR on a victim, the apparatus comprising a pad or other structure configured to be applied to the chest near or at the location at which the rescuer applies force to produce the chest compressions, at least one sensor connected to the pad, the sensor being configured to sense movement of the chest or force applied to the chest, processing circuitry for processing the output of the sensor to determine whether the rescuer is substantially releasing the chest following chest compressions, and at least one prompting element connected to the processing circuitry for providing the rescuer with information as to whether the chest is being substantially released following chest compressions.

An exemplary method of identifying a source of chest compressions administered during cardiopulmonary resuscitation (CPR) includes receiving, at a processor, signals indicative of pressure exerted during the chest compressions from at least one sensor communicatively coupled to the processor and disposed at a location on the victim's chest away from an indicated compression point for manual chest compressions, generating a compression waveform based on the received signals, detecting compression waveform features representative of the chest compressions based on the compression waveform, comparing the detected compression waveform features to a pre-determined criterion to discriminate between chest compressions from an automated compression device and manual chest compressions, determining whether the chest compressions are from the automated compression device or the manual chest compressions based on the comparison, and generating an output based on whether the chest compressions are determined to be from the automated compression device or the manual chest compressions.

A gait motion assisting apparatus of the present invention includes an actuator unit controlling driver so that assisting force calculated by applying gait motion timing based on detected thigh phase angle to output pattern saved data is imparted to lower leg, and a terminal device capable of wireless-communicating with control device of the actuator unit. The terminal device can receive assisting force setting value including assisting force imparting period during gait cycle and create, based on the assisting force setting value, output pattern setting data indicating a relationship between the gait motion timing and a size of assisting force to be imparted to the lower leg. The control device is configured to overwrite-save the output pattern setting data received from the terminal device as the output pattern saved data.

The present invention provides a device with a pressure control system and methods for controlling the application of negative pressure to an external surface of an individual for creating and/or maintaining patency of the upper airway passage. The device is configured to fit under the chin of a subject at an external location corresponding approximately with the subject's internal soft tissue associated with the neck's anterior triangle. The pressure control system contains control module elements that may include circuit board elements, digital output barometer elements, sensor elements, processing elements and memory elements to optimize device function and safety of the device through regulation of the flow rate of the air pump.

This disclosure includes manipulating apparatuses and related methods. Some manipulating apparatuses include an actuator having a semi-rigid first segment, a semi-rigid second segment, and one or more flexible cells disposed between the first segment and the second segment, where the actuator is configured to be coupled to a fluid source such that the fluid source can communicate fluid to vary internal pressures of the one or more cells, and where each cell is configured such that adjustments of an internal pressure of the cell causes angular displacement of the second segment relative to the first segment.

A device may include a high-level control layer comprising a convolutional neural network (CNN) configured to receive exoskeleton sensor data from one or more sensors on an exoskeleton and generate a user state estimate. The device may include a mid-level control layer configured to receive the user state estimate and generate a torque command for an actuator based on the user state estimate. The user state estimate may be an estimated gait phase, where the mid-level control layer generates the torque command as a function of the estimated gait phase based on an assistance profile. The high-level control layer may include a backward labeler and a real-time adaptation trainer. The backward labeler relabels ground truth gait phase from the exoskeleton sensor data using a local peak detection. The real-time adaptation trainer trains the CNN in a single epoch of backpropagation with the ground truth gait phase.

A motorized tensioning mechanism for orthotic devices, such as a knee brace, wherein the controls for the motorized tensioning mechanism may be manual, automatic, or a hybrid of both. Sensors associated with the orthotic device may inform the user regarding tension or other aspects of the device, and, in cases, may automatically adjust tension in the motorized tensioning mechanism.

A wearable gait detection device, a walking ability improvement system and a wearable gait detection system detect manifestation in a brain based on the wearer's gait and preventive measures. A load measurement part measures a load of a sole of the wearer's feet, a foot movement detection part at the shoes detects acceleration and/or angular velocity during feet movement, a centroid position calculation part calculates a centroid position of the feet based on changes in measured load, a movement locus calculation part calculates a movement locus of the feet based on acceleration and/or angular velocity detected by the foot movement detection part, a manifestation recognition part recognizes manifestation in the brain according to a specificity of centroid fluctuation of the feet based on the calculated centroid position and movement locus of the feet, and a sensory output part feeds back a sensation to the wearer based on a recognition result.

A standing-up assistance apparatus includes a first sensor that measures a muscle potential of a lower leg of a user, a second sensor that measures a knee angle of the user, a processor that determines whether starting to assist the user in a standing-up motion from a seated state is possible, based on, at least, the measured muscle potential and the measured knee angle, and outputs an instruction signal if the processor determines that starting to assist the user in the standing-up motion is possible, and an assistance mechanism. The assistance mechanism starts assisting the user in the standing-up motion when the assistance mechanism receives the instruction signal from the processor.
