A positively-positionable mounting apparatus having a ball mount, a multisided positionable mount, and a coupler. The coupler includes two relatively rigid arm members and a clamp structured to secure the arm members together in an operatively juxtaposed configuration. Each of the arm members is formed with a part hemispherical socket adjacent to a first end, the socket structured to cooperate with the ball mount to form a securely positionable ball-and-socket assembly. Each of the arm members is also formed with a multisided partial collar adjacent to a second end, the partial collar structured to cooperate with the multisided positionable mount to form a positively-positionable wheel-and-axle assembly.

In one aspect a unique mirroring of channels from the wireless portion to a hard-wired link provides for mutual access and sharing of overall bandwidth from and to individual transceivers. emperature distribution; and making post-processing to show the calculating results. 5. The ship hull-piece forming method according to claim 1, wherein said database-construction step (a) comprises: (a-1) information modeling containing the flow of data in a formation process of a ship hull-piece on a basis of an object-oriented concept; (a-2) definition of the product model about the formation process of the ship hull-piece on a basis of the object-oriented concept, in which product model data cover all information over a total life cycle--design, production and waste--of specific product such as phase #1, phase #2, phase #3, and phase #4; wherein phase #1 is the selection of objects, including hull-piece and kinematics, bending strains and in-plane strains, principal curvature and piece forming method, rolling and rolling conditions, line-heating and heating conditions, material property and NURBS surface, offset table and surface measuring, measuring points and measuring sequence, heating line set and heating sequence, and communication method and ANN model phase #2 is the definition of attributes and respective relationship; phase #3 is the setup of constraints; and phase #4 is the model integration of these objects; and (a-3) construction of the product database which the forming information is saved to and retrieved from on a basis of such product model. 6. An information-generation system for ship hull-piece formation comprising: a measurement module in which a shape of a plate and forming information is measured; a numerical analysis module in which heating conditions are calculated and verified, using a numerical analysis program for thermal elastic-plastic analysis; a display module in which forming information is displayed, via a monitor, and is printed, via a printer; a data access module in which measuring and forming information is stored to and retrieved from a product database and a STEP physical file that has measuring and forming information is available; an inference module in which forming information and heating conditions regarding the plate are predicted from data of the product database by using an artificial neural network method; an information-generating and control module in which each module previously described is controlled and is obtained through calculation of in-plane and bending strains in the processing stages, wherein heating paths or locations are determined; a communication module through which the information-generating and control module transmits forming information, heating conditions and heating paths to a numerical control machine through which the measured and formation results are transmitted and stored to the product database. 7. The information-generation system as claimed in claim 6, wherein the heating paths for transverse formation are determined perpendicularly to maximum principal directions of bending strains by calculating a ratio between maximum and minimum principal bending strains, and the heating paths for longitudinal formation are determined perpendicularly to maximum principal directions of in-plane strains by calculating a ratio between maximum and minimum principal in-phase strains. 8. The information-generation system as claimed in claim 6, wherein the numerical analysis program is executed by: setting up parameters, including the size of the plate, an initial curvature of the plate, a speed of a torch, the clearance between the torch and a cooler, a film coefficient, and a number of finite elements; setting up material properties, including a conduction coefficient and a specific heat quality, to model a heat source and a cooling method; calculating temperature distribution in each time step; and making post-process to show calculating results; and setting up material properties, including a conduction coefficient, an elastic coefficient, a thermal expansion coefficient, a yield stress; determining boundary conditions; calculating stra
