    The GuideCane is a device designed to help blind or visually impaired users navigate safely and quickly among obstacles and other hazards. During operation, the user pushes the lightweight GuideCane forward. When the GuideCane's ultrasonic sensors detect an obstacle, the embedded computer determines a suitable direction of motion that steers the GuideCane and the user around it. The steering actio...

    We present an approach based on genetic algorithms for performing camera calibration. Contrary to the classical nonlinear photogrammetric approach, the proposed technique can correctly find the near-optimal solution without the need of initial guesses (with only very loose parameter bounds) and with a minimum number of control points (7 points). Results from our extensive study using both syntheti... View full abstract»

    The problem of multiple faults diagnosis in safety-critical systems is considered. Error propagation between system components is modeled as a directed graph, where the errors propagate instantaneously along the edges. Some of the system components are equipped with alarms, which ring when abnormal conditions are detected. A diagnosis algorithm identifies the set of potential failure sources based...

  • Quantification of arm kinesthetic sense using an arm motion generator

    Publication Year: 2001, Page(s):137 - 142

    The human response caused by the motion of an object grasped by a human operator is defined as an arm kinesthetic sense. Due to nonlinearity and ambiguity of human senses, there is no absolute standard for quantification of kinesthetic sense. In this research, a so-called two-dimensional (2-D) arm motion generator is developed to emulate various mechanical impedance, i.e., stiffness or damping, ch... View full abstract»

    A large class of engineering systems are modeled by coupled differential and algebraic equations (DAE). Due to the singular nature of the algebraic equations, DAE systems do not satisfy the standard state-space description and require special techniques. So far, the literature has concentrated mostly on the numerical analysis and control of DAE systems. This paper investigates the problem of healt... View full abstract»

    A methodology of modeling and analysis of planar mechanical systems is developed based on graph theoretic methods, with improvements in component models. The system model based on cutset and circuit topologies is used to derive a new hybrid cutset-circuit method of formulation of the equations of motion for planar systems. Computer-aided formulation is based on analysis of the substitution procedu... View full abstract»

    We present a practical and systematic strategy for measuring machine intelligence quotient (MIQ) of human-machine cooperative systems. So far, much research related to intelligent control has been established, but the issues about definition and measurement of machine intelligence are not yet clearly formulated. We propose the intelligence task graph (ITG) as a modeling and analysis tool. By using... View full abstract»
