Abstract: A microprocessor-controlled mobile machine for curing a floor coating includes a source of radiant energy in the form of ultraviolet (UV) light which is mounted to the machine. The machine may be operated in a Traverse mode under operator control of speed for moving to an application site. A Standby mode permits the UV applicator to operate at a quiescent state to reduce warm-up time while permitting the machine to be maneuvered by the operator. A Cure mode (of which there may be a plurality) operates the machine at predetermined, processor-controlled speed and the UV applicator at a predetermined power level.

Abstract: A system for measuring the tenderness of meat includes a probe equipped with a force transducer which generates an electrical signal having an instantaneous amplitude representative of the penetration resistance force encountered by the probe during insertion to a predetermined depth. The transducer is connected in a bridge circuit which is energized by a storage battery coupled to the bridge through a regulating network to insure a constant supply voltage for the resistive transducer. An amplifier receives the force signal and couples it to a memory circuit which includes a capacitor fed by a unidirectional current-carrying circuit. The capacitor stores a charge proportional to incremental increases in the transducer signal; and since it does not discharge except by operator reset, the charge stored after the probe comes to rest is representative of the peak penetration resistance force and, thus, a measure of the tenderness of the meat.
