The invention relates to process for roughening thermoplastic films and roughed films. The invention further relates to process for preventing thermoplastic packaging films from slipping on each other and a suitable system for such purpose. The essence of the roughening process is that practicles consisting of the same polymer as that of the film and/or other plastic material being able to weld together with that, and having suitable size and/or abrasion resistance are brought to the surface to be roughened of semi-finished product having sufficient reserved heat content to maintain condition appropriate for welding said particles on said thermoplastic film surface to be roughened or on one or on both film surfaces being re-heated to such temperature and are dispersed in suitable closeness and configuration and that condition of the roughened surface is maintained until desired welding process is completed. Process for preventing thermoplastic packaging films from slipping on each other characterised in that a system comprising films to be stacked-at least one of which is roughed-and has protrusions of suitable closeness on its surface; a binding element having a loose fibrous structure and stability is placed on the film or on its specified parts, on the entire surface or on surface pan(s); said binding element comprises fiber of such closeness and layer thickness that between the fiber of the binding element and the protrusions of the roughed film a mechanical joint is formed.

The invention provides multi-textured animal treats and methods for making the multi-textured animal treats. In a general aspect, the multi-textured animal treat includes one or more soft component comprising a mechanical joint that is wrapped around a hard component fixedly attached to the mechanical joint on the soft component.

Robotic mobility assistant exoskeleton with frame members, which are attached adjacent to biological joints, supplements relative movement between skeletal members. Mechanical joint defines a center of relative rotation of frame members about three mutually perpendicular axes with the center of relative rotation of frame members being displaced from the outer surfaces of skeletal members to correspond in position with the center of biological joint. Actuation devices including powered cable springs rotate frame members. Control system executes calibrated user specific posture sequences and activates power. Mechanical joint exhibits cylindrical guide surfaces defining a slidable or rotatable connection of frame members and has a radius intersecting the center of the biological joint. Node control network distributes computing load and reduces communications overhead. Map unit has object recognition system for monitoring environment. Standard posture data derived from rules of ambulation and posture provide positioning control, optimized by energy-timed margins for balance maintenance.

The present invention is directed to an autonomous exoskeleton device that includes one or more actuators, one or more controllers, one or more sensors with one or more unidirectional transmissions. The present invention provides a mechanical joint in parallel with a biological joint. The exoskeleton device preferably includes and electric motor and winch, chain, belt, cam transmission or other mechanism for providing unidirectional force to assist rotation about the biologic joint. Moreover, a controller, a motor angle sensor, joint angle sensor and/or force sensor may be used for additional control and monitoring of the device. The motor may be any type of motor, but is preferably brushless in configuration where its diameter is larger than its length to provide a compact and lightweight exoskeleton device.

The invention discloses an anti-winding locating device for a 360-degree rotary joint of a robot. Locating of the joint is achieved by an edge signal of a zero Hall switch, a Z-pulse signal of an incremental encoder and an edge signal of a limiting Hall switch on the basis of the zero Hall switch and the limiting Hall switch. Thus, on one hand, the precision and the automatic degree are improved when the robot carries out zero locating, and the problem that an electric lead is wound on a mechanical joint is solved; on the other hand, the problem that the electric lead is wound when the joint normally moves is solved under the situation that a work space is 360 degrees. The anti-winding locating device has the advantages of low cost, simple structure, ease in operation and high precision.
