Disclosed are an apparatus and method of processing an audio signal to optimize audio for a room environment. One example method of operation may include recording the audio signal generated within a particular room environment and processing the audio signal to create an original frequency response based on the audio signal. The method may also include identifying a target sub-region of the frequency response which has a predetermined area percentage of a total area under a curve generated by the frequency response, determining whether the target sub-region is a narrow energy region, creating a filter to adjust the frequency response, and applying the filter to the audio signal.

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 for controlling a damping modification in an artificial knee joint of an orthosis, an exoskeleton, or a prosthesis. The artificial knee joint has an upper part pivotally connected to a lower part A resistance unit is secured between the upper part and the lower part in order to provide a resistance against a flexion or extension The resistance unit is paired with an adjustment device to modify the resistance when a sensor signal of a control unit paired with the adjustment device activates the adjustment device. The flexion resistance is reduced for the swing phase. A curve of at least one load characteristic is detected when walking or standing; a maximum of the load characteristic curve when standing is ascertained; and the flexion damping is reduced to a swing-phase damping level during the standing phase when a threshold of the load characteristic below a maximum is reached.

Prosthetic and/or orthotic devices (PODS), control systems for PODS and methods for controlling PODS are provided. As part of the control system, an inference layer collects data regarding a vertical and horizontal displacement of the POD, as well as an angle of the POD with respect to gravity during a gait cycle of a user of the POD. A processor analyzes the data collected to determine a locomotion activity of the user and selects one or more control parameters based on the locomotion activity. The inference layer may be situated between a reactive layer control module and a learning layer control module of the control system architecture.

A prosthetic foot assembly is disclosed. The assembly includes a pivoting ankle joint with a hydraulic system, a prosthetic foot connected to the distal side of the ankle joint, and, at the proximal side, the ankle joint includes a transducer with pyramid adaptor for attaching to a pylon. The ankle joint sensor provides data collection during the stance and optionally, the swing, phases of walking using, for example, strain gages and accelerometers. Also disclosed are methods for real-time feature extraction. Key parameters are captured to which are applied linear, fuzzy logic, neural net, or generic algorithms to determine current state (walking flat, uphill, downhill etc.) in real time and execute changes to the angle between the ankle and foot almost instantaneously based on those parameters.

The application relates to an orthopedic device comprising a joint and to a method for controlling an orthopedic device, which has an upper part and a lower part supported pivotally thereon, wherein upper connecting means for fixation onto a limb are disposed on the upper part, and a locking device, which prevents a bending motion of the upper part relative to the lower part, wherein the locking device is configured such that it can be actively actuated by the user of the orthopedic device, wherein a control device is associated with the locking device, the control device being attached to the device with at least one sensor and automatically unlocking or locking the locking device as a function of the sensor signal.

A method of controlling a prosthetic hand having at least one motorised component is provided. The method comprises the steps of providing the hand with a first wireless transceiver and a controller in communication with one another, storing at least one manipulation instruction relating to the at least one component, and assigning a code relating to the at least one manipulation instruction to at least one second wireless transceiver. The at least one second transceiver is placed in a location at which the at least one manipulation instruction is to be given, and the controller manipulates the at least one component in accordance with the at least one manipulation instruction when the first transceiver communicates to the controller that the at least one second transceiver is within a predetermined distance of the first transceiver. Related methods and systems for controlling a prosthetic hand are also provided.
