Abstract: Disclosed examples include programmable circuitry to obtain source-identifying information from a media request message, the source-identifying information indicative of a media-requesting source associated with the media request message; determine a partner affiliation status of the media-requesting source based on a comparison of the source-identifying information with a source category identifier from a data collection facility, the partner affiliation status indicative of whether the media-requesting source has a partnership with a media provider to provide audience measurement information associated with the server system; and insert a delay tag in a media response message to the media-requesting source based on the partner affiliation status, the delay tag corresponding to a delay time period.

Abstract: Methods, apparatus, systems and articles of manufacture are disclosed to throttle resource access by web crawlers. An example method disclosed herein includes obtaining, at a server, a media request message for media hosted by the server, the media request message requesting access to the media, characterizing a media-requesting source associated with the media request message, and inserting a time delay in a media response message to the media-requesting source based on the characterization.

Abstract: Example headsets and methods for gathering electroencephalographic signals are disclosed herein. An example headset disclosed herein includes a cap to be worn on a head of a person and a first electrode carried by the cap. The first electrode holder defines a first opening therethrough. The example headset includes a first electrode that insertable into the first opening. The first electrode has a first length and is adjustable in the first opening to a first plurality of discrete positions having different depths of insertion relative to the first opening. The first electrode is to engage the head of the person when inserted a sufficient depth into the first opening. The example headset also includes a second electrode that is interchangeable with the first electrode and insertable into the first opening.
