    Abstract: The invention proposes a device, e.g. an inspection pig, for inspecting conduits made from ferromagnetic materials, such as pipelines, for faults, cracks, corrosion or the like, comprising at least one pulling element, a supporting structure of variable circumference, disposed on the pulling element and comprising substantially radially disposed supporting arms each of which is pivotable about axes disposed perpendicular to the longitudinal central axis of the pulling element, and several permanent magnets disposed at the circumference of the supporting structure for generating a magnetic field, and with sensors. For strengthening or weakening the magnetic field generated by the permanent magnets in dependence on the circumference of the supporting structure or in dependence on the lateral separation between the permanent magnets, the permanent magnets are associated with further magnets having a magnetic field which can be varied in direction or strength. In an embodiment, the further magnets associated with the permanent magnets are permanent magnets, wherein the direction of their magnetic field can be changed by turning using an electric or mechanical actuator. In another embodiment coils are used as magnets, which can be supplied with a variable current.

    Abstract: A computerized pool cue and a controller device are provided which are connected to a computer screen to simulate and display playing a game of pool or billiards. The pool cue is supported above an underlying surface for movement in at least two dimensions with respect to the underlying surface. Movement of the pool cue with respect to game balls in play is shown on the computer screen. A signal is generated from the pool cue to the computer for coaction with software to simulate the game of pool or billiards on the computer screen without using actual game balls.
