Abstract: A clock architecture including a clock source, a multi-phase clock signal generator, a control bus, a number of clock signal lines, and at least one circuit block. The clock source generates a global clock signal, which is then transferred to the multi-phase clock signal generator connected to the clock source. Upon receipt of global clock signal, the multi-phase clock signal generator, which is connected to a control bus, generates clock signals of different phases according to the signals from the control bus. Each of the clock signal branches transfers one of the clock signals of different phases, wherein each of the clock signal branches is individually connected to the circuit block through an electrical switch. Only one switch is at an on state at one time, so that the clock signal of a corresponding phase is transferred to the circuit block. The driving forces applied on the clock buffer connected to the clock source and the clock buffers on the branches are adjustable for reducing clock skew.

Abstract: A new generation of hybrid form multi-axis machine tools is described. The hybrid machine tools comprise a position mechanism and an orientation mechanism. Both mechanisms are three-DOF parallel mechanisms that can be connected either in series to form a hybrid parallel-serial manipulator, or in parallel to form a cooperating machine. The position mechanism is used for manipulating the position and the orientation mechanism is used for manipulating the orientation of an object. Six-axes machining of a workpiece is achieved by coordinating the motions of the position and orientation mechanisms. This approach has several important advantages. First of all, a high stiffness, low inertia, and high speed machine tool is realized by using the parallel construction. Secondly, its direct and inverse kinematic solutions could be solved in closed forms which would greatly simplify the control and path planning problems. Thirdly, it has a relatively large workspace in comparison to fully parallel platform manipulators.

Abstract: A new and innovative concept for the control of backlash in gear-coupled transmission mechanisms. The concept utilizes redundant unidirectional drives to assure positive coupling of gear meshes at all times. Based on this concept, a methodology for the enumeration of admissible redundant-drive backlash-free robotic mechanisms has been established. Some typical two- and three-DOF mechanisms are disclosed. Furthermore, actuator torques have been derived as functions of either joint torques or end-effector dynamic performance requirements. A redundantly driven gear coupled transmission mechanism manipulator has a fail-safe advantage in that, except of the loss of backlash control, it can continue to function when one of its actuators fails. A two-DOF backlash-free arm has been reduced to practice to demonstrate the principle.
