The speed of in-plant vehicles such as forklift trucks and the like is monitored to provide for the lighting of a warning light where a first speed threshold is reached, the sounding of a horn when a second speed is reached, and for the disabling of the vehicle on the sustaining of the higher speed for a predetermined interval of time. This speed monitoring approach generates a signal having an intermittent monitor output corresponding with the speed of the vehicle and which exhibits a period of lessening duration in corresponding with increasing speeds. Timing of the occurrence of these signals is employed with an accumulator based logic to establish vehicle speed. To avoid apparatus reaction to noise based signals, a select number of occurrences of apparent speed excursions are required before the horn or lamp are activated. Remote supervisory resetting of the monitoring system following the occurrence of a latched warning output is provided through an IR based code transmitting and receiving arrangement.

Speed monitoring of in-plant, operator controlled vehicles

Apparatus for simultaneously forming one or more lines of multi-character messages on the surface of solid material which employs an array of marker pins which are moved by a carriage along a singular plane locus of movement defining a sequence of rows corresponding with a pixel matrix. The locus includes a retrace feature for each row or transverse movement which enhances the quality of character formation. An actuator assembly develops the locus of movement and, in turn, is driven by facing cam wheels which, in turn, are powered from an electric motor. A manifold which receives pneumatic pulses from arrays of conduits is coupled to the carriage and a marker head assembly, in turn, is removably coupled to the manifold. An array of solenoid actuated valves is coupled to the tubing arrays and to a pneumatic source which may be remotely positioned from the manifold.
