US Classification:

709219, 709203

Abstract:

In one embodiment, a method includes accessing data associated with one or more source logs. The data associated with the source logs corresponds to activity of a user at a particular time. The method also includes identifying the user and a device associated with the source logs; and mapping at least a portion of the data associated with the source logs to a user session associated with the user and the device. The user session corresponds to activity of the user while using the device. The information also includes providing data corresponding to a particular period of time based on the user session. The data corresponds to the particular period of time includes streaming content and geographic data captured during the particular period of time.

International Classification:

H04R 9/02

Abstract:

An electromechanical transducer (e.g., or ) includes a motor structure and voice coil winding support structure or former ( or ) configured with a vented annular spacer (e.g., ) and vented distal pole tip member (e.g., ) having aligned radial channels aimed to transport heat away from a voice coil ( or ) during the transducer's reciprocating movement while providing an extended, linear dynamic range and continuous cooling for the voice coil. A dual magnetic gap embodiment has an inside annular spacer member (e.g., A) and a co-planar outside annular spacer member (e.g., -O), each made of a thermally conductive steel alloy.
