Abstract: The present disclosure provides a system for detecting the contamination condition of lubricating grease of a mechanical component. The system comprises a radio frequency signal generator, a sensor, a switch assembly and a radio frequency signal analyzer. The radio frequency signal generator generates a radio frequency signal with a frequency higher than 1.0 GHz. The sensor contacts lubricating grease to be sensed in the mechanical component. The switch assembly switches between a first mode, in which a radio frequency signal is transmitted through a first transmission path, thereby providing a first feedback signal for the radio frequency signal analyzer, and a second mode in which the radio frequency signal is transmitted through a second transmission path, thereby providing a second feedback signal for the radio frequency signal analyzer. The radio frequency signal analyzer analyzes the first and second feedback signals to detect the contamination condition of lubricating grease.

Abstract: An isothermal drop speed cooling method and an apparatus for same. A glass ribbon carried with glass passes through the forced convection area of the glass annealing lehr, and the glass ribbon is moving while the glass is being air-cooled in the forced convection area. The glass is air-cooled by different air volume according to the temperature of the glass, so that the glass is allowed to be cooled at isothermal drop speed during the moving process of the glass. According to the cooling method and apparatus, the specification size of the opening section of multi-row air nozzles longitudinally arranged is increased along the moving direction of the glass ribbon, so that the cooling air volume from the front to the rear can be gradually increased, thereby allowing the temperature drop speed of a glass plate to be uniform from the front to the rear.

Abstract: One or more systems and/or methods of generating a query-goal-mission structure for a set of queries are provided. A set of queries may be evaluated to identify query information for the queries within the set of queries. The queries may be evaluated as query pairs to determine common goal probabilities (e.g., likelihood two queries correspond to a particular goal, such as to identify vacation planning information) for the query pairs. Responsive to the common goal probabilities for the query pairs exceeding a goal probability threshold, the query pairs may be grouped into goal clusters. The goal clusters may be evaluated as goal cluster pairs to determine common mission probabilities. Responsive to the common mission probabilities for the goal cluster pairs exceeding a mission probability threshold, the goal clusters may be grouped into mission clusters. The mission clusters and the goal clusters may be utilized to generate a query-goal-mission structure.

The feature is evaluated to identify a goal (e.g., finding snow boots) associated with the feature. A mission (e.g., finding outdoor apparel), associated with the goal, is identified. A query (e.g., “outdoor stores near Akron”) associated with a second goal (e.g., find outdoor apparel store) associated with the mission is identified using a model generated utilizing a machine learning method trained using a query-goal-mission structure. A query recommendation (e.g., “outdoor apparel store”) comprising the query is presented to the user. A user satisfaction metric, associated with the query, the query recommendation, a result generated by the query recommendation, etc. is determined based upon user interaction with the query recommendation and the result.
