Abstract:

An acoustic sensor for measuring acoustic waves contained in fluid flow flowing over the sensor. The acoustic sensor reduces any unwanted self-noise associated with the flowing fluid by providing a nose cone having proper aerodynamic properties and by positioning the diaphragm of a microphone of the sensor at a location where any unwanted noise is at a relatively low level. The nose cone has a rounded, blunt or even sharp tip neither of which creates any major disturbances in the flowing fluid which it intercepts.

Abstract:

A digital magazine server presents content to a user that includes various content items. The user may provide a comment to the digital magazine server for association with a content item and may identify an additional user in the comment. To allow the user to more easily identify the additional user, the digital magazine server associates information identifying users who have performed actions with the content item in association with the content item. The digital magazine server compares information in a request to provide a comment to the information identifying the users who have performed actions with the content item and presents the user with information identifying users who have performed actions with the content item that at least partially matches a portion of the information in the request.
