Abstract: An industrial truck, in particular a counterbalanced front-forklift truck, is provided which can be operated both manually and automatically and has a fork to handle pallets and loads located thereon. The forklift truck is equipped for automatic operation with a control system which can be brought into active connection with the vehicle drive system, the vehicle steering system, the vehicle braking system or the movement control system for the fork.

Abstract: A navigation system for an autonomous mobile robot within an environment which comprises coded signs at predetermined points comprising means for storing data regarding said environment, including data regarding the positions of said coded signs relative to the environment, passive vision systems for the image acquisition and automatic recognition of said coded signs, a computer for estimating its own position and orientation relative to one of said coded signs and to the environment, means for acquiring the location of target positions, means for planning a path to be covered within said environment to reach target positions, and means for controlling the robot motion based on the stored path data.

Abstract: A system for determining the location of a seismic wave source in a homogeneous medium (the soil) comprises a linear array of equispaced sensors sampled by respective pulse extractors in turn feeding a plurality of cascaded two-dimensional recursive digital filters which act as phase shifters estimating in small or incremental steps the magnitude of the wave field away from the sensor array. The output signals of the sensors are sampled at a rate equal to the ratio of the distance between the sensors and the wave velocity in the homogeneous medium, thereby giving rise to samples distributed in a single quadrant of the space-time domain. An attenuator connected in series with the phase-shifting filters damps frequency components outside the rotated quadrant, while an equalizer connected in cascade with the attenuator ensures a global linear response thereof.
