Abstract: A heat dissipation device (30) includes a base (50) and a plurality of individual fin plates (40) standing side by side on the base. Each fin plate includes a main body (41), a flange (43) and a pair of tabs (45) distal from the flange. Each tab defines a split (46) in a middle thereof where it adjoins the corresponding main body and thereby forms a tongue (47) surrounded on three sides by the split. The tongue is coplanar with the main body while the flange and the tabs are perpendicular to the main body. A slot (49) is defined in a distal end of each tab. The flanges of the fin plates are in alignment with each other and attached on the base. The slots of each fin plate receive the tongues of an adjoining preceding fin plate.

Abstract: A soccer kicking practice device. The device has a movable platform or running surface, such as a motorized treadmill, for forcing the user to run while practicing, and a movable kick target, both the movable platform and movable target mounted on a stationary base. Preferably, the practice device has a hand rail and a body harness for steadying and retaining the user. Elevating apparatus enables the practice device to elevate its front end or its rear end, to simulate uphill and downhill inclination of terrain. Controls enable speed of the treadmill and of the kick target to be adjusted, and the elevating apparatus to operate as desired. Optionally, the treadmill is lined with artificial turf. Automated scoring apparatus is optionally provided for recording and totalizing the number of kicks.

Abstract: A device for mounting a tubular sleeve for an obturator of a trocar to a patient's body includes a sleeve-holding part for attaching to the sleeve and a skin-fixation part for attaching to the patient's skin surface. The sleeve-holding part may be formed by an annular washer made of an elastic material which permits a user to move it longitudinally with respect to the sleeve so as to adjust their relative positions. The skin-fixation part may be a crossbar and a cord attached to the washer at one end and to the crossbar at the other. The cord is stapled to the patient's body for fixation.
