Abstract: An anti-locking mechanism of a spherical compressor rotor, an anti-locking power mechanism of a spherical compressor, and a spherical compressor. A pin boss is fixedly arranged on a turntable shaft, and guide pins are movably connected with a guide sleeve. A concave slideway is arranged in a cylinder block spherical surface or a cylinder lower spherical surface, and is distributed along a sliding track of the guide sleeve on the corresponding cylinder block spherical surface or cylinder lower spherical surface in a rotation process of a turntable. A main shaft rotates and drives the turntable. When the turntable rotates to a position at which a turntable axis and a piston axis are superposed, the turntable can continue to rotate around the turntable axis by means of torque obtained by the guide pin from the concave slideway, and thus a problem of a dead point of movement of a spherical compressor rotor is solved.

Abstract: An apparatus and method are provided for ranking content categories. Multiple sessions of usage data is collected for usage activities of a plurality of users (associated with a group) on a plurality of categories of content. The usage data is analyzed for an average group usage of each category across the sessions and a variation of the average group usage of each category across the sessions. Individual usage data is also collected for usage activities of at least one user on the categories of content. The individual usage data reflects an aggregated usage of each category for the at least one user. Category usage is estimated on each category for the at least one user based on a weighted combination of the aggregated usage and the average group usage according to the variation. An amount of weight of the aggregated usage in the weighted combination is inversely related to the variation.
