Abstract: A recommendation system associated with an online marketplace can generate recommendations pertaining to users and assets of the online marketplace by computing user-asset propensity scores. The recommendation system can compute a corresponding user-asset propensity score for each unique user-asset combination. Based on the scores, recommendations indicating predicted user behavior can be generated. To generate the user-asset propensity scores, the recommendation system can generate machine-learned models based on training data. The model can comprise a plurality of classifiers each being associated with user-asset attributes.

Abstract: A glow in the dark paddleboard and/or wakeboard is disclosed that is visible in low-light conditions. The paddleboard and/or wakeboard comprises a top surface visible in low-light conditions. Preferably, the paddleboard and/or wakeboard comprises at least one glow in the dark element that is photoluminescent following sufficient exposure to a recharging source. The paddleboard and/or wakeboard are used in surface water sports and allow a user to traverse the surface of a body of water. However, when the user is in or near the water at night, or in other low-light scenarios, the glow in the dark element radiates visible light enabling a companion, or a rescuer to better visualize the user, thereby increasing the likelihood of a successful retrieval or rescue if required, and also prevents accidents as passing boats and other watercraft are more likely to see the individual and not run them over.

Abstract: A glow in the dark wetsuit is disclosed that is visible in low-light conditions. The wetsuit comprises an outer surface visible in low-light conditions with at least one fastener for securing the wetsuit on a user. Preferably, the wetsuit comprises at least one glow in the dark element that is photoluminescent following sufficient exposure to a recharging source. The wetsuit insulates the user from cold water when submerged and protects the user from injury from marine life or from abrasions when diving in the water under any light condition. However, when the user is in or near the water at night, diving deep underwater, or in other low-light scenarios, the glow in the dark element radiates visible light enabling a companion, a dive buddy, or a rescuer to better visualize the user.

Abstract: An architecture is presented that provides a glow in the dark flotation device that increases the likelihood of quickly locating individuals lost in water by increasing the visibility of the user, and more particularly to a durable conventional life jacket having a phosphorescent portion that emits visible light under low-light conditions.

Abstract: The present invention comprises a chemical mechanical polishing tool comprising a polishing platen and a removable, replaceable platen top mounted on a top surface of the platen. Preferably, the platen top comprises a material substantially impervious to the slurries used when planarizing an object. Most preferably, the platen top comprises aluminum alloy or glass. The platen top may be tailored to provide enhanced polishing conditions by acting as an insulator, a conductor or machined to be concave or convex. The invention may further include endpoint sensors attached to the platen top.

Abstract: A semiconductor post-polishing processing apparatus and method employing a non-optical wafer sensor for detecting the presence of a semiconductor wafer within the processing stations. The apparatus comprising a wet processing station, a wafer transport track, and the non-optical sensor. Preferably, the non-optical wafer sensor is a transducer, and most preferably, a piezo element, which emits and detects sound waves. The sound waves are reflected back to the emitter signaling the presence of a semiconductor wafer. The signal is sent to a receiver linked to a processor which is adapted to move a wafer holder situated at the end of the transport track to receive a wafer in the next available empty slot of the holder. The non-optical wafer sensor is impervious to slurry and CMP residue, film build-up, bubbles, wafer color/hue variations, and other wet environment problems.

Abstract: An apparatus for polishing a semiconductor wafer is provided which includes a wafer carrier having on its lower surface a non-uniform surface structure means to vary the force against a wafer during a polishing operation so that the polishing is enhanced and imparts a planar surface across the polished wafer. Preferred non-uniform surface structure means include use of a wafer carrier having on its lower surface a backing film having a first central portion having a predetermined compressibility and a second peripheral portion having a different compressibility than the first portion. Another non-uniform surface structure means to vary the force against the wafer comprises a wafer carrier having on its lower surface a raised circumferential region around the periphery of the carrier.
