  • Patent number: 7921066
    Abstract: A method of predicting the behavior of software agents in a simulated environment involves modeling a plurality of software agents representing entities to be analyzed, which may be human beings. Using a set of parameters that governs the behavior of the agents, the internal state of at least one of the agents is estimated by its behavior in the simulation, including its movement within the environment. This facilitates a prediction of the likely future behavior of the agent based solely upon its internal state; that is, without recourse to any intentional agent communications. In the preferred embodiment the simulated environment is based upon a digital pheromone infrastructure. The simulation integrates knowledge of threat regions, a cognitive analysis of the agent's beliefs, desires, and intentions, a model of the agent's emotional disposition and state, and the dynamics of interactions with the environment.

  • Patent number: 7853360
    Abstract: A PWM signal on which a dither signal is superimposed is used for adjusting a central position when controlling a solenoid valve. To improve this type of control process in which the amplitude of the dither signal depends on the current of the solenoid valve and thus on the PWM signal, the PWM signal and the dither signal are generated in a computer unit independently of the power regulation process. Forming the signals separately has the advantage of generating a constant amplitude for the dither signal each time a triggering signal is generated for the solenoid valve such that the armature of the solenoid valve can oscillate specifically about the central position and thereof at constant small vibrations. This allows frictional forces to be reliably reduced and the solenoid valve to be switched more rapidly while the load on the main computer is reduced.

Angular and rectilinear misalignment amounts of the target object in the angular and rectilinear directions are calculated, with reference to detection and reference values of a signal output from the optical sensor, and at least one of detection and reference values of a radius of the target object. A controller controls the transfer unit to compensate for the angular and rectilinear misalignment amounts in transfer of the target object by the pick.

  • Patent number: 7529599
    Abstract: The invention provides systems and methods that integrate and/or control motion of a plurality of axes in a motion control environment. Grouped axes can be linked (e.g., via a tag) to provide desired multi-axis coordinated motion as well as provide control for corresponding aspects of motion such as acceleration, velocity, etc. Such axes can be integrated with other control functionality such as process and/or machine control to provide the user with a comprehensive control. The foregoing can provide simple mechanisms for moving devices in multiple axes of a coordinate system in a coordinated fashion. Such coordinated move functionality can provide a user-friendly interface for linear and circular moves in multi-dimensional space. The algorithm employed for path planning can provide fast execution and dynamic parameter changes (e.g., maximum velocity, acceleration and deceleration) along a desired path of motion.

  • Patent number: 7515991
    Abstract: In cleaning using a self-propelled cleaning device, firstly the cleaning device moves alongside a wall surface and then a reference direction is set. Next, the cleaning device advances alongside the wall surface at a prescribed distance, makes a right-angle turn, and travels in the reference direction. When the cleaning device reaches the surface of an opposing wall, it moves in a spiraling manner. At that time, the orientation angle of the cleaning device, which is estimated using a gyro sensor, is checked and corrected. If an obstacle is encountered while traveling, the cleaning device travels on a path that avoids the obstacle or travels in a spiral manner in a region in front of the obstacle.

  • Patent number: 7496415
    Abstract: A digital servo control unit which uses a D/A converter, which suppresses the spike-like pulsation superimposed on a current error signal inside a current control circuit, and which has control performance not lower than that in the background art even when a low-voltage and low-price power supply circuit is used. A first-order low pass filter acts on an analog signal output by the D/A converter, and a stabilizing compensation occurs for a phase delay caused by the first-order low pass filter. The first-order low pass filter is formed as a low pass filter having a cut-off frequency which is lower than a sampling frequency. The first-order low pass filter may be replaced by a notch filter having a cut-off frequency which is equal to a sampling frequency or which is equal to an integer multiple of a Nyquist frequency.

  • Patent number: 7487069
    Abstract: A method for optically detecting the position of a moveable test object (10), especially a mirror or reflector, in which a measuring beam (6) produced by a light source (2) is reflected by the test object (10 and reaches a position-sensitive light detector (12) which carrier out a conversion into information corresponding to the position of the test object (10). The invention enables the position of mirrors, especially rotating mirrors, to be quickly measured optically using a simple optical construction. The measuring beam (6) is focused onto the light detector (12) by an optical system (8). A signal corresponding to the geometric center or the maximum (I0) of the intensity distribution of the focused measuring spot is determined based on the measured values obtained by the light detector (12).

  • Patent number: 7477965
    Abstract: A twisted wire actuator, whereby the shortening of the length of a wire or a bundle of wires, as it is twisted, is used to control the motion of an actuated element, achieving sub-micron motion resolution. The control can be performed robotically. The high resolution can be achieved without the use of gears, sliders, or high precision lead screws, thus enabling a simplified actuation system and eliminating sources of friction. The use of wires operating in opposing directions and having oppositely directed rotations significantly reduces the non-linearity effect inherent in twisted wire actuation, resulting in a system having a good level of motion linearity as a function of control input impulse. The use of multiple twisted wires attached to the actuated element at different angles, enables the implementation of robotic systems with multiple degrees of freedom. Several experimental actuators verify these results.

  • Publication number: 20080281441
    Abstract: There is described a method and a device for positioning an element of a machine. A setpoint position variable is generated, said setpoint position variable is reduced by means of a limiting variable and a modified setpoint position variable which is forwarded as a setpoint variable to a controller for positioning the element is formed in this manner. An expected setpoint position variable is determined from the modified setpoint position variable, the braking distance of the element is determined from the expected setpoint position variable, and a braking process of the element is initiated if the braking distance matches a target position which is reduced by the expected setpoint position variable. An element of a machine can so be positioned with accuracy.
