A system for control of a prosthetic device includes at least one Inertial Measurement Unit detecting orientation of a user's foot. The at least one Inertial Measurement Unit is in communication with a device module configured to command at least one actuator of a prosthetic device. The at least one Inertial Measurement unit sends output signals related to orientation of the user's foot to the device module and the device module controls the at least one actuator of the prosthetic device based on the signals from the at least one Inertial Measurement Unit.

A method of calculating in vivo force on an anterior cruciate ligament (ACL) by measuring one or more biomechanical properties during a biomechanical screening task to obtain one or more biomechanical datum from the measured one or more biomechanical properties, and calculating a total load on an anterior cruciate ligament from an ACL force model using the one or more biomechanical datum as inputs to the ACL force model. The ACL force model is defined by F.sub.ACL=F.sub.ACL.sup.sag+F.sub.ACL.sup.front+F.sub.ACL.sup.trans+Σ.sub.jCT.sub.j, wherein F.sub.ACL is the total force on the ACL, F.sub.ACL.sup.sag is the force on the ACL in a sagittal plane, F.sub.ACL.sup.front is the force on the ACL in the frontal plane, F.sub.ACL.sup.trans is the force on the ACL in the transverse plane, and CT.sub.j is the ACL force interaction relationships among the sagittal-frontal (SF), sagittal-transverse (ST), and frontal-transverse (FT) planes, where j=SF, ST, FT.

In at least some aspects, the present concepts include a method for configuring an assistive flexible suit including the acts of outfitting a person with an assistive flexible suit, monitoring an output of at least one sensor of the assistive flexible suit as the person moves in a first controlled movement environment, identifying at least one predefined gait event using the output of the at least one sensor, adjusting an actuation profile of the at least one actuator and continuing to perform the acts of monitoring, identifying and adjusting until an actuation profile of the at least one actuator generates a beneficial moment about the at least one joint to promote an improvement in gait. The at least one controller is then set to implement the actuation profile.

A sleep mask includes a flexible eye cover configured to be worn by a late-term pregnant female and configured to cover and shield the eyes of the wearer from ambient light. At least one light source is carried by the flexible eye cover and positioned to emit light having a wavelength of 450 to 570 nm onto the eyelids of the wearer when asleep and penetrate the eyelids when closed. A controller is connected to the at least one light source and configured to activate the light source to decrease endogenous melatonin levels and suppress uterine contractions in the late-term pregnant female.

Disclosed is an audio-headset for acquisition of a bio-signal from a subject, including a first earpiece; a second earpiece; an arch connecting the first earpiece and the second earpiece; the arch including a hub (4); wherein the arch, the first earpiece and the second earpiece are configured so that the earpieces are placed over a subject's ears when the audio headset is worn by the subject; and at least one posterior branch (1) having a first end extending from the hub and a second free end; the at least one posterior branch (1) including a concave surface with a radius of curvature, a collapsed state when the headset is not worn by the subject and an expanded state when the headset is worn by the subject.

The present invention discloses a carbon dioxide inhalation treatment device for central sleep apnea comprising a blower, a gas cylinder filled with carbon dioxide (CO.sub.2), an airbag, a mask, and a detection mechanism for detecting the central apnea by measuring the electromyographic activity of the chest wall muscles. The mask is provided with multiple holes providing a communication between the inside and outside of the mask in order to prevent any sense of resistance of breathing and to provide greater control of inspired CO.sub.2. Inspired CO.sub.2 from a gas mixture containing also a minimum 20% O.sub.2 is driven by air using a blower into a mixing chamber. This carbon dioxide inhalation treatment device for central sleep apnea can provide a stable, mild level of carbon dioxide for patients with central sleep apnea, thus by preserving respiratory drive correcting central sleep apnea without increasing the arousal and microarousal frequency.

Systems and methods are disclosed for conducting spinal cord stimulation or other neurostimulation and sensing evoked compound action potential (ECAP) signals. The sensed signals may be processed to isolate ECAP features from noise and/or interfering signals. The isolated ECAP features may be used to control neurostimulation therapy for the patient and/or guide an implant procedure.
