A suitable waypoint is selected using a goal score, a section from a start point to a goal point through the waypoint is divided into a plurality of sections based on the waypoint with a solution of inverse kinematics, and trees are simultaneously expanded in the sections using a Best First Search & Rapidly Random Tree (BF-RRT) algorithm so as to generate a path. By this configuration, a probability of local minima occurring is decreased compared with the case where the waypoint is randomly selected. In addition, since the trees are simultaneously expanded in the sections each having the waypoint with a solution of inverse kinematics, the solution may be rapidly obtained. A time consumed to search for an optimal motion path may be shortened and path plan performance may be improved.

This invention vaporizes a botanical substance for inhalation using a combustion generated heat source. A substantially planar non-porous heat exchanger transfers heat to the inhalation air and keeps combustion byproducts separated from the inhalation air. In use, air is drawn past the heat exchanger and then through a reservoir holding the botanical substance, vaporizing any volatiles in the substance. The heat exchanger assembly can be magnetically attached to the pipe assembly.

The present invention provides methods, systems, kits and devices that reduce dyskinesis and hypokinesis. For example, the direct compression cardiac device may be positioned about at least a portion of a heart, and includes a resilient inner panel in contact with at least a portion of the heart periphery, one or more resilient members positioned about the resilient inner panel and at least partially surrounded by an expandable outer panel. The resistance supplied by the inner panel to the heart may be modulated to control the end-diastolic heart volume and remodel the heart, the resistance supplied by the expandable outer panel to the heart may be modulated to control the end-systolic heart volume and remodel the heart or both.

A method of positioning a patient or person 0 to 90 degrees in an upright position or greater in a supine or prone position while maintaining neutral skeletal alignment (non flexed position) with a body positioning mattress capable of applying a vacuum process to remove air; molding the mattress around the body to maintain position. A means to place the support mattress onto a manual or motorized bed frame to position and maintain a patient or person 0 to 90 degrees or greater in the supine or prone position.

A skin retention device 10 for a medical jet-injection unit 20 comprises a contact face provided with adhesive 12 in the area surrounding and close to the injection opening(s) 11 of the nozzle 21 which ensures god contact between the nozzle 21 and the skin 30 of a subject in the area chosen for an injection. Consequently the injection force can be lowered dramatically. In case of two-stage jet-injections, the initial injection force can be lowered because the skin retention close to the injection point significantly reduces the energy consuming elastic expansion of the skin 30 in the injection area, and the second injection force can be lowered because of the high degree of fixed positioning of the injection opening of the nozzle 21 relative to the injection channel in the skin 30 made during the initial injection stage. Thus a high degree of injection safety is achieved, minimizing the risk of whet shots, while skin lift and lower injection force decreases the risk of damage of the underlying tissue.
