This data processing system for a pattern generator receives data specifying each quadrilateral element in a pattern to be generated by laser scanning or other technique. The scanning is accomplished by swaths. In the preprocessor, separate vectors are produced for the portion of each quadrilateral edge in each swath. A real time processor, including a "pipeline" or cascaded set of beam processors...

For grinding a tyre 2 mounted on a vehicle, an abrasive band 5 stretched around rollers 51, 52, 53, 54 and 46 mounted on a frame 4 is used. A jack 7 takes all weight off the tyre 2. A counterweight 45 pulls the frame 4 towards the tyre 2. The pressure of the abrasive band 5 against the tyre 2 can be adjusted to a very low value.

The invention relates to a process for the production of foams based on polyisocyanates by reaction of polyisocyanates, compounds having at least two hydrogen atoms which are reactive toward isocyanate groups, blowing agents and if appropriate other additives. A blowing agent which consists to the extent of at least 10 mol % of one or more branched dodecafluorohexanes is used here.

To smoothly switching the steering direction of the vehicle automatically driven along a road, leftward and rightward steering angles ( theta L, theta R) are obtained on the basis of leftward and rightward white lines and by means of leftward and rightward cameras (7, 8) and image processors (9, 10) and a calculator (12), respectively. The obtained leftward and rightward steering angles are compa...

In a remotely piloted surface vehicle a television camera is used to send images to a screen on the operator's station. A computer displays the vehicle's intended path on the screen. The path appears as a computer-generated line superimposed on the image of the vehicle's environment, like a stripe painted on the ground. The operator can change or advance the path on the screen with a cursor contro...

Apparatus to prevent endless switchover attempts between processors in redundant processor systems where each processor resets an associated watch dog timer (WDT). Whenever a WDT times out, WDT sends a restart signal to its associated processor and a failure signal to switchover control logic. The switchover control logic causes a switch from the active processor to the standby processor if the st...
