Abstract: Methods and apparatus to count people are disclosed. Example people counting apparatus disclosed herein include a difference calculator to calculate a degree of similarity between a first characteristic dataset and a second characteristic dataset representative of face detections in images. Disclosed example people counting apparatus also include a limiter to store the first characteristic dataset and the second characteristic dataset in a plurality of characteristic datasets associated when the degree of similarity does not satisfy a threshold, and to store the first characteristic dataset in the plurality of characteristic datasets and discard the second characteristic dataset when the degree of similarity satisfies the threshold to limit a number of stored characteristic datasets. Disclosed example people counting apparatus further include a comparator to compare the plurality of characteristic datasets to each other to determine a number of unique faces in an environment during a first period of time.

Abstract: Methods, apparatus, systems and articles of manufacture are disclosed to monitor WI-FI media streaming using alternate access points. An example apparatus disclosed herein monitor wireless traffic includes an example traffic monitor to identify a connection of a WI-FI client to a primary access point and capture a management frame transmitted from the primary access point to the WI-FI client. The example apparatus further includes an example frame generator to insert a change channel announcement into the captured management frame and a router to cause a wireless interface to transmit the beacon frame to the WI-FI client.

Abstract: Example metering apparatus and related methods are disclosed. An example apparatus disclosed herein includes a stencil and a housing having a display area. The display area has a first recessed cavity and a second recessed cavity adjacent the first recessed cavity. The first recessed cavity is offset relative to the second recessed cavity such that the second recessed cavity defines a front surface of the display area and a peripheral lip of a front side of the housing. A cover is removably coupled to the housing to enable access to the display area. The second recessed cavity of the housing is to receive the cover. The cover is received by the second recessed cavity such that an outer surface of the cover is substantially flush mounted relative to a peripheral lip of the housing, and wherein a perimeter of the cover is substantially similar to a perimeter of the peripheral lip.
