Abstract: A robotic shoe which provides real-time feedback regarding forces acting on the foot of the user, in order to modify these forces in a corrective or diagnostic manner. The shoe comprises an insole equipped with embedded pressure sensors enabling it to continuously monitor the ground reaction forces (GRF) and the foot center of pressure (COP) while the user is standing, walking, and running. The insole COP and GRF readings are input to a programmable system that shifts the COP trajectory dynamically in a patient-specific manner via the robotic platform of the shoe. The robotic platform contains motors that control elements whose movement manipulates the forces acting on the foot and lower limb, resulting in modification of the GRF. Closed loop feedback enables a dynamic fit of an optimal COP. The COP and GRF information can be stored for analysis and diagnosis of gait and instability events accruing during locomotion.

Abstract: An airfoil surface skin, comprising a network of a solid material, embedded in a base of deformable solid material. Fluid pressure applied to the interface between the network and the surrounding embedding material, opens an internal network of channels by viscous peeling of the surrounding solid from the network. The network is offset from the centerline the surround material, such that pressure driven viscous flow through the narrow channels generates two types of deformation of the skin—an in-plane elongation and a curvature of the skin plane itself. The shape of the internal solid core element and its material, and the material of the encompassing solid are chosen to achieve a desired integral structural rigidity. The injected fluid pressure determines the extent of extension and bending. Use of this skin enables shape amending airfoils having reduced drag compared with similar airfoils having conventional flap mechanisms.

Abstract: A high-efficiency, motorless purge system for closed-cycle absorption heat pumps, adapted for both absorption heat transformers and absorption chillers, using a series of valves to control the entry and exit of absorbent solution into a low-pressure, secondary absorption vessel. A small percentage of the total circulating solution is forced under pressure into the secondary absorption vessel via a spray nozzle, causing adiabatic absorption of absorbate vapor by the solution. Non-condensable gases accumulate in the secondary absorber until a certain vapor pressure is reached, upon which, gas, and possibly liquid, are transferred to an exhaust vessel having an exit vent for non-condensable gases. In an absorption chiller system, the secondary absorber has an internal heat exchanger to lower the temperature of the solution within, to facilitate the absorption process.

Abstract: A vacuum arc thruster device having a cathode rod disposed within a concentric insulator tube, and an anode electrode located at the distal edge of the insulator tube, separated from the cathode rod by the insulator tube. A controlled feeding mechanism moves the cathode towards the distal exit plane in a helical motion, the cathode rotating as it moves forward. The cathode rod is fixed in the center of a headless screw segment, which is rotated within a screw thread on the internal surface of a cylindrical wall of the device. As the erosion rate is concentrated at the exit plane, the screw action path enables uniform erosion around the cathode circumference, and cathode linear motion that can be matched to the radial erosion rate. The feeding rate and hence the thrust are proportional to the input power, which can be regulated by the pulse frequency.
