Abstract: A system and an apparatus for positioning a plurality of flexible cleaning lances through tubes penetrating a tube sheet of a heat exchanger tube sheet, includes a smart lance tractor drive, a controller, and a tumble box connected to the controller operable to generate and/or distribute electrical power to the AC induction sensor from an air pressure source, supply electrical power to the controller and distribute pneumatic power to pneumatic motors for positioning the tractor drive on the positioner frame. The smart tractor drive includes sensors for detection of mismatch between expected and actual lance positions, sense lance insertion distance and lance removal and provide automated drive reversal operation to remove blockages within tubes being cleaned.

Abstract: A laser heater assembly for a vaporizer includes a power source, a laser source, a lens, and a reaction chamber. The lens is disposed within the optical path. During operation, the laser source emits light, the light propagating along an optical path during operation of the light source. The lens receives the emitted light from the laser source, and outputs a modified light having an energy profile that is substantially spatially uniform. The modified light traverses at least a portion of an opening of the reaction chamber and vaporizes a vaporization substance (e.g., a dry plant material) received within the reaction chamber. The emitted light can be collimated light, and the modified light can be a homogeneous line profile beam.

Abstract: At least one aspect is directed to determining an estimate of an intersection of user identifiers in a first set of user identifiers and a second set of user identifiers. The first and second sets of user identifiers can be populated with user identifiers that have interacted with the same content item or content item campaign. Estimates of intersections of the first and the second sets can be determined based on a binomial vector approach, a vector of counts approach, or a hybrid approach. The binomial vector approach generates vectors based on k hashes of each user identifier in the first set and summing the vectors to generate a first vector. The intersection can be determined based on a dot product of the first vector and a second vector similarly generated from the second set of user identifiers.

Abstract: A connection device for fastening two expanded cellular confinement structures includes: an insertion member; an integral shank extending perpendicular from the insertion member; and an integral handle member extending perpendicular from the shank at an end of the shank remote from the insertion member. One or more barbs may project from the insertion member. The device can have a washer section between the handle member and insertion member. The handle can be curved, or it can be in the shape of a polygon.

The first and second sets of user identifiers can be populated with user identifiers that have interacted with the same content item or content item campaign.

Abstract: A cooping appliance which has a multi-layer lid, the lid preferably includes three spaced layers and venting between the outer and middle layers such that the outer most layer remains cooler to the touch compared to prior art grills. The lid preferably can comprise materials of relatively low melting points or burning points such as polymers or leather or wood or other decorative materials which ordinarily would get too hot on a grill lid. The outer layer is preferably curved in shape with the middle and inner layers formed from a number of straight sections with bends therebetween.
