  • Publication number: 20150202780
    Abstract: A robotic arm includes first and second bent links and a tool link pivotally connected in order, first to third wheels, and first to fourth imaginary axes intersecting at a center of spherical rotation. The first bent link and wheel are driven to rotate about the first and third imaginary axes respectively. A first flexible rope is wound around the first and second wheels and fixed to the second bent link for driving the second wheel and bent link to rotate about the second imaginary axis when the first wheel rotates. A second flexible rope is wound around the second and third wheels and fixed to the first bent link for driving the third wheel and the tool link to rotate about the fourth imaginary axis when the second wheel rotates. The robotic arm is relatively smaller, obstructs the operator less and produces a wider sphere of action.

  • Patent number: 8924898
    Abstract: An automated processor design tool uses a description of customized processor instruction set extensions in a standardized language to develop a configurable definition of a target instruction set, a Hardware Description Language description of circuitry necessary to implement the instruction set, and development tools such as a compiler, assembler, debugger and simulator which can be used to develop applications for the processor and to verify it. Implementation of the processor circuitry can be optimized for various criteria such as area, power consumption, speed and the like. Once a processor configuration is developed, it can be tested and inputs to the system modified to iteratively optimize the processor implementation. By providing a constrained domain of extensions and optimizations, the process can be automated to a high degree, thereby facilitating fast and reliable development.
