Abstract: A product on demand nozzle assembly includes a chamber at least partially defined by an external wall and an array of vertically spaced nozzles. Each nozzle has an air inlet, an air and entrained product outlet extending from the external wall, and an entrainment zone between the air inlet and the air and entrained product outlet to receive a product therein to be distributed.

Abstract: A center slide assembly for a multi-point exit device. Upper and lower spool assemblies may be displaced from first positions to second positions along an inner region of a center slide. The displacement of the spool assemblies may displace upper and lower pull cables so as to retract latch mechanisms from extended positions to retracted positions. A first latching pin may be displaced, along with the displacement of the upper spool assembly, along an abutment surface of a tilting link so as to pivotally displace the tilting link from an unlocked position to a locked position. Displacement of the lower spool assembly may displace a second latching pin to a position wherein the second latching pin may be received and retained within a jog of the tilting link when the tilting link is in the locked position, which may thereby retain the associated latch mechanism in the retracted position.

Abstract: A brushroll dowel for a vacuum cleaner has a bristle stiffener protruding from a brush dowel. A plurality of stiffened bristles protrude from the brush dowel adjacent to the bristle stiffener, and a plurality of unstiffened bristles also protrude from the brush dowel and are non-adjacent to the bristle stiffener.

Abstract: A surface cleaning apparatus includes a recovery tank, a suction nozzle in fluid communication with the recovery tank, and a suction source in fluid communication with the suction nozzle and the recovery tank to generate a working air path to transport debris-containing fluid including air and liquid from the suction nozzle into the recovery tank. An air/liquid separator can be provided within the recovery tank for separating liquid from air in the debris-containing fluid.

Abstract: A surface cleaning apparatus is provided with a nozzle cover having multiple functions, including sealing an opening for an above-the-floor vacuum hose, aiding in removal of a suction nozzle from the apparatus and acting as a handle for the suction nozzle upon removal of the suction nozzle from the apparatus. A locking mechanism prevents the suction nozzle from accidentally releasing from the apparatus when the vacuum hose is installed.

Abstract: A brushroll dowel for a vacuum cleaner having bristle stiffeners protruding from a brush dowel. The brushroll can be made using an injection molding process, with the bristle stiffeners integrally molded with the brush dowel and a plurality of stiffened bristles protruding from the brush dowel adjacent to the bristle stiffeners.

Abstract: Calculating a failure intensity value for a group of search sessions is provided. In one example, a method for calculating a failure intensity value for a group of search sessions is provided. The method includes obtaining, by a computing device comprising a processor device, the group of search sessions, where each search session of the group of search sessions includes user input that identifies a search query. The method further includes classifying each search session of the group of search sessions into one or more result categories, where each result category is indicative of an outcome of a search session. The method additionally includes calculating the failure intensity value for the group of search sessions based on a combination of weighted values of the group of search sessions, where the weighted values are based on the one or more result categories of the group of search sessions.

Abstract: A method of tufting, with a tufting tool, a brushroll dowel for a vacuum cleaner having a bristle stiffener protruding from the dowel and a bristle hole adjacent the bristle stiffener. The tufting tool includes a notch. The method provides a brushroll with bristles tufted into the bristle hole adjacent the bristle stiffener. A brushroll for a vacuum cleaner can be made using an injection molding process, with bristle stiffeners integrally molded with the dowel and a plurality of stiffened bristles protruding from the brush dowel adjacent to the bristle stiffeners.

Abstract: Systems and methods for actuating a tactile stimulation in response to detecting a specific event associated with exposure to a particular environmental or physiological condition are described herein. A tactile stimulation device, according to one of several implementations, comprises a sensing layer, an actuating layer, and an adhesive layer. The sensing layer, which is sensitive to exposure to a particular condition, is configured to sense when a specific event associated with exposure to the particular condition occurs. The actuating layer is configured to provide a tactile stimulation to a human subject when the specific event occurs. The adhesive layer is configured to affix the sensing layer and actuating layer with respect to a surface portion of the skin of the human subject such that the human subject can sense the tactile stimulation provided by the actuating layer. The sensing layer, actuating layer, and adhesive layer can be bonded together to form a relatively flat structure.
