Abstract: A device developed specifically to perform adhesive sheet cutting operation, with one antiskid face (Sandpaper), which is applied over a Skateboard Shape upper face. It is a grip (E1), in which rear end a geometric volume (V1) is formed, which upper face (F1) is bent downward; and between bent face (F1) highest region and grip (E1) rear end upper corner is formed by a recess (R1) with ‘C’ letter shape cross-section, and a knife end (N1) is slightly projected beyond recess (R1), limits, standing over bent face (F1) region.

Abstract: Described herein is a method for enabling human-to-computer three-dimensional hand gesture-based natural interactions from depth images provided by a range finding imaging system. The method enables recognition of simultaneous gestures from detection, tracking and analysis of singular points of interests on a single hand of a user and provides contextual feedback information to the user. The singular points of interest of the hand: include hand tip(s), fingertip(s), palm center and center of mass of the hand, and are used for defining at least one representation of a pointer. The point(s) of interest is/are tracked over time and are analyzed to enable the determination of sequential and/or simultaneous “pointing” and “activation” gestures performed by a single hand.

Abstract: A swimming pool sculpture, according to the invention, is mounted on the edge of an above-the-ground pool. Recirculating water from the pool's filtration system is redirected back into the pool through the sculpture in the nature of a "spray" or "stream". In a preferred embodiment, the sculpture has a body portion secured to the ledge of the pool, and rotatable head portion through which the "spray" or "stream" is directed; with the head being interchangeable with others of like design, a swimming pool toy-accessory of different appearance and/or "spray pattern" may be provided, and one which requires no complex moving parts or piping systems, makes full use of the water available in the system, and maintains the whole area of the pool available for swimming. In an alternative construction of the invention, a valve may be added, to vary the pressure of the recirculating water introduced into the sculpture, and, thereby control the distance of the "spray" or "stream" into the pool.
