Abstract: A gas collapsible stove includes an expandable combustion chamber formed from nested annular rings that can collapse to about the height of a single ring and expand into a combustion chamber for burning combustible materials. Ventilation holes at the bottom of the combustion chamber provide airflow into the combustion chamber. The combustion chamber is frustoconical and narrows at the top which increases air flow into the combustion chamber via the Venturi effect. Combustible fuels can be added and ignited in the combustion chamber and cookware containing food can be placed onto an associated top plate suspending the combustion chamber. A gas head with a plurality of gas apertures can be inserted through a bottom plate secured to the bottommost annular ring to allow a combustible gas to be used as a combustible fuel in the combustion chamber.

Abstract: A brain-machine interface is provided that incorporates a neural dynamical structure in the control of a prosthetic device to restore motor function and is able to significantly enhance the control performance compared to existing technologies. In one example, a neural dynamical state is inferred from neural observations, which are obtained from a neural implant. In another example, the neural dynamical state can be inferred from both the obtained neural observations and from the kinematics. A controller interfaced with the prosthetic device uses the inferred neural dynamical state as input to the controller to control kinematic variables of the prosthetic device.

Abstract: Artificial control of a prosthetic device is provided. A brain machine interface contains a mapping of neural signals and corresponding intention estimating kinematics (e.g. positions and velocities) of a limb trajectory. The prosthetic device is controlled by the brain machine interface. During the control of the prosthetic device, a modified brain machine interface is developed by modifying the vectors of the velocities defined in the brain machine interface. The modified brain machine interface includes a new mapping of the neural signals and the intention estimating kinematics that can now be used to control the prosthetic device using recorded neural brain signals from a user of the prosthetic device. In one example, the intention estimating kinematics of the original and modified brain machine interface includes a Kalman filter modeling velocities as intentions and positions as feedback.

Abstract: A reel comprises a motorized spool member about which a linear material can be wound. A housing surrounds the spool member and has a port through which the linear material extends. A motor controller detects when the linear material is pulled from the spool member through the port, and responds by operating a motor to rotate the spool member in an unwind direction. During this operation, the motor controller (1) uses a spool sensor system to detect an unwind rate at which the linear material is unwound from the spool member, (2) uses a translation sensor system to detect a pull-out rate at which the linear material is pulled through the port in the unwind direction, and (3) adjusts the motor speed based on the detected rates, to limit a length of unwound linear material between the spool member and the port to less than a predetermined length.
