A method for controlling movement using an active powered device including an actuator, joint position sensor, muscle stress sensor, and control system. The device provides primarily muscle support although it is capable of additionally providing joint support (hence the name “active muscle assistance device”). The device is designed for operation in several modes to provide either assistance or resistance to a muscle for the purpose of enhancing mobility, preventing injury, or building muscle strength. The device is designed to operate autonomously or coupled with other like device(s) to provide simultaneous assistance or resistance to multiple muscles.

Systems and methods for noninvasive assessment of cardiac tissue properties and cardiac parameters using ultrasound techniques are disclosed. Determinations of myocardial tissue stiffness, tension, strain, strain rate, and the like, may be used to assess myocardial contractility, myocardial ischemia and infarction, ventricular filling and atrial pressures, and diastolic functions. Non-invasive systems in which acoustic techniques, such as ultrasound, are employed to acquire data relating to intrinsic tissue displacements are disclosed. Non-invasive systems in which ultrasound techniques are used to acoustically stimulate or palpate target cardiac tissue, or induce a response at a cardiac tissue site that relates to cardiac tissue properties and / or cardiac parameters are also disclosed.

A cockpit display system has a display, such as a multi-function display (MFD) for displaying a graphical representation of an input device when a sensor senses that an aviator's finger is proximate to the input device. The display graphically depicts in real-time the position of the aviator's finger relative to the buttons of the input device. The aviator's finger can be depicted by an icon, shading or highlighting. When the aviator lightly touches a button, the graphical representation of that button can for example be highlighted, shaded or colored. Furthermore, when the button is firmly depressed, the graphical representation of that button can change color or shading. The aviator can thus operate any awkwardly located input device by simply reaching toward the input device and then guiding his finger to the correct button by looking at the graphical representation of the input device.

An actuator device (2) includes a piezoelectric or electro-strictive solid state actuator element (6) that is elongated upon application of an electric voltage thereto, and a transmission mechanism (8) that amplifies the stroke displacement of the actuator element. The transmission mechanism (8) includes a plurality of rigid frame members (12), including unitary frame members (12.1, 12.2) and divided frame members (12.3), and elastically flexible joints (10) that respectively interconnect the frame members. Each one of the divided frame members (12.3) is made up of a plurality of separate parallel link rods (16). Each flexible joint (10) is made up of a plurality of individual parallel hinge members (18) that respectively connect an end of each one of the link rods (16) to the adjacent unitary frame member (12.1, 12.2). By this division of the flexible joints and of the divided frame members into parallel sub-components, the cross-sectional thickness of each individual hinge member is reduced, and thereby the bending stiffness and the outer fiber strain of the material of the hinge members is significantly reduced while providing the same total tensile strength and tensile stiffness. The link rods of each divided frame member effectively form a parallelogram linkage for moving and guiding the output members (12.1) in a parallel manner.

The invention specifies a method and system for leading a person suffering from “sympathetic predominance”, a specific symptom of which is “hypertension”, to breathe according to a certain pattern for the express purpose of positively altering the condition of sympathetic predominance (over activation), having the effect of bringing the autonomic nervous system into the state of balance, with consequent reductions in “tenseness”, blood pressure, muscular tightness, and emotional strain, as well as the alleviation of the myriad of subtle neuro-physiological consequences resulting from sympathetic predominance potentially including headaches, anxiety, sleep disorders, allergies, and other maladies that have yet to be attributed to this condition, thus leading to a general improvement in health, well being, and homeostasis.
