Abstract: In variants, the method for automatic debris detection includes: determining a region image; optionally determining a parcel representation for the region image; generating a debris representation using the region image; generating a debris score based on the debris representation; and optionally monitoring the debris score over time.

Abstract: A system for delivering fluid, e.g. liquefied petroleum gas or "LPG", through a delivery path (10) under pressure. A delivery control valve (16) is selectably operable to close and open the delivery path (10) and monitors a parameter of the fluid, e.g. dielectric constant, and to sense the presence of vapor or gas phase in the fluid. A control means (30) responsive to the indicating signal from the sensing means (20) causes the delivery control valve (16) to close the delivery path upon sensing the presence of a significant proportion of vapor or gas phase in the fluid. A gas introduction point (35) upstream of the sensing means (20) enables gas to be introduced so as to knowingly expose the sensing means (20) to fluid containing gas phase and thereby enable controlled testing of the correct functioning of the sensing means (20).

Abstract: A pneumatic tire with tread composed of a sulfur cured rubber comprised of, based on the rubber (A) cis 1,4-polyisoprene; (B) at least one of isoprene/acrylonitrile rubber and butadiene/acrylonitrile rubber and, optionally; (C) at least one additional rubber which includes cis 1,4-polybutadiene characterized in that the cis 1,4-polybutadiene is a primary rubber constituent.

Abstract: A vehicle tire (10) has a tread (20) with a plurality of ribs (30,31,32) extending circumferentially about the tread. The ribs each have a pair of lateral edges (48,49;60,61) which comprise edge segments placed end to end to present a zigzag configuration. Each rib has grooves (37,38;39,40) therein which intersect the lateral edges of the respective rib and have varying depths at said lateral edges. Preferably, the tread has an all-season configuration.

Abstract: The present invention relates to novel biologically active tricyclic compounds, of the general formula I: ##STR1## and salts thereof, in which R.sub.1 represents hydrogen, alkyl of 1-6 carbon atoms, an optionally substituted aralkyl group or an acyl group,R.sub.2 represents hydrogen, alkyl (1-6 C), or an optionally substituted aralkyl group, orR.sub.1 +R.sub.2 together with the nitrogen atom represent a heterocyclic 5- or 6-membered ring, p1 X and Y each represent hydrogen, hydroxy, halogen, alkyl or alkoxy of 1-6 carbon atoms, nitro, CF.sub.3 or an acyloxy group, andthe dotted line signifies an optional extra bond.The compounds of the general formula I have valuable anti-depressant activity without a sustained influence on appetite.
