Abstract: Oppositely directed sensors (41,42) determine separately that an object is moving in a normal or opposite to normal direction along a path (16) when signals reflected back from the object indicate that it has moved further than a preset minimum distance in either of the two directions. A warning device (14) is activated if one of said sensors (41,42) indicates that an object is moving in the opposite to normal direction. 
     If the two sensors disagree, a third sensor (43) is activated to confirm which sensor (41,42) is correct. If two of the three sensors (41,42,43) indicate opposite to normal motion, a signal indicating the same is sent to a base station. A fourth sensor (44), on detecting said object, sends a further signal to the base station indicating that an object has passed the warning device 14. 
     Sensors 41 and 42 are used by themselves in a second embodiment, and in both cases are turned off and on in cycles to save power.

Abstract: The ink duct has an open frame (3), in which an ink roller (1) is rotatably mounted and a doctor blade carrier (2) is retained. The doctor blade carrier is arranged such that its gap-forming edge lies above the centre line of the axis of rotation of the roller. The roller and the doctor blade thus together form an ink trough. This arrangement results in the roller and doctor blade carrier flexing in the same direction during operation. With corresponding dimensioning and mounting of the roller and the doctor blade carrier, a uniform ink layer can be applied to the roller regardless of the viscosity of the ink and regardless of the circumferential speed of the ink roller. <IMAGE>

Abstract: Delay analysis in logic simulation is enhanced by providing, in a simulation model of a logic circuit, a timing delay tag on each circuit path connecting the output (30;10) of a first (BLK1;BLK4) with the input (A0,D01) of the second circuit element (BLK4;BLK3). Each circuit leg is given a delay value and a clock phase tag providing information about how the delay value is clocked. The clock phase tags (T0,...,T3) correspond to respective phases of a multi-phase circuit clock and relate the delay values to particular clock phases. The phase tag also indicates whether the signal on the data path is triggered by the rising (R) or falling edge of the specified clock phase. At circuit nodes, clock phase tags are concatenated. Thus, if a clocked circuit element responds to an input signal which is a composite of several upstream output signals, the concatenated clock phase tags and delay values can be analyzed to determine if a timing adjustment is required. The information further supports the automatic adjustment of delay value, if needed.
