Abstract: Systems and methods for generating a viewer-specific visitor history for a location are provided. In particular, a visitor history for a particular viewer and location can indicate a total number of users who have visited the location and can specifically identify one or more of a set of users using a facepile. The set of specifically identified users can be those users that have an associative link with the viewer and that are also associated with at least one location signal for the given location and for which the particular viewer is a permitted viewer. Thus, location signals having varying scopes of visibility information can be aggregated across a plurality of different web-services to provide a single, unified visitor history for a particular location and viewer, all while respecting user-specified visibility information.

Abstract: A sound system, the sound system including: (a) a signal processor that is adapted to generate a first sound signal and a second sound signal, to provide the first sound signal to a loudspeaker; and to provide the second sound signal to a bone conduction speaker; and (b) the bone conduction speaker that is adapted to transduce the second signal to a bone conductible sound signal that is carried in a bone of a user.

Abstract: A formation surrounding a borehole is traversed with a logging tool employing an acoustic transmitter and a pair of spaced-apart acoustic receivers. Acoustic energy traveling through the formation from the transmitter to the receivers are detected. The energy of tube waves contained within the detected acoustic energy is measured. Such measured tube wave energy is calibrated in response to measurements of tube wave energy ratio carried out in a zone of the formation having zero permeability. This calibrated tube wave energy is transformed into formation permeability in accordance with a measured relationship between permeability and tube wave energy ratio.
