Metering device

Example apparatus disclosed herein includes a grouper to generate a first presence indication based on a threshold number of segments of image data including patterns of light values corresponding to a first human pulse. Disclosed example apparatus also include a face identifier to identify a first location associated with a human face in an environment associated with the image data based on thermal imaging data from a thermal imaging device, and output the first location associated with the human face in the environment associated with the image data.

Methods and apparatus to detect people

A retainer apparatus includes a post having a first end to be received by an opening of a wall plate cover of an outlet and a second end opposite the first end. At least a portion of the post has a plurality of grooves positioned between the first end and the second end. The plurality of grooves forming a retainer-receiving portion. A plug retainer is moveably coupled to the post. The plug retainer to slide along the retainer-receiving portion in a linear direction relative to the grooves when the plug retainer is moved relative to the retainer-receiving portion of the post.

Plug retainer apparatus and related methods

Media metering device

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. The second electrode has a second length, greater than the first length, and is adjustable in the first opening to a second plurality of discrete positions having different depths of insertion relative to the first opening. The second electrode is to engage the head of the person when inserted a sufficient depth into the first opening.

Methods and apparatus to gather and analyze electroencephalographic data

Stencil of a media metering device

Example retainer apparatus and related methods are disclosed. An example retainer apparatus disclosed herein includes a post having a first end attachable to a wall plate cover opening of an outlet and a second end opposite the first end. The example retainer apparatus also includes a plug retainer to be removably coupled to the post. The plug retainer of the example retainer apparatus is to move relative to the post between the first end of the post and the second end of the post.

Connected device

Example apparatus disclosed herein include processor circuitry and memory including machine executable instructions which, when executed, cause the processor circuitry to generate a first presence indication based on a threshold number of portions of an image including a first human pulse waveform. The example instructions, when executed, also cause the processor circuitry to identify a first location associated with a face in the image based on thermal imaging data, and adjust a first count based on a comparison of the first location associated with the face and a second location associated with the first presence indication.

Methods and apparatus to detect people are disclosed. An example method includes detecting a first human pulse waveform in first light information associated with a first one of a plurality of segments of an environment, the light information obtained from a light sensor. Generating a first presence indication in response to respective light information associated with a threshold amount of the segments proximate the first one of the segments includes the first human pulse waveform identified in the first one of the segments. Identifying a first location associated with a face in the environment using thermal imaging data from a thermal sensor. Adjusting a people count in response to the first location associated with the face not corresponding to a second location associated with the first presence indication.

Methods and apparatus to detect people are disclosed. An example apparatus includes a receiver to obtain respective light information for a plurality of segments of an image, each of the segments corresponding to a portion of a media exposure environment; a pulse identifier to detect a first human pulse pattern in the light information associated with a first one of the segments; and a grouper to determine whether the light information associated with a threshold amount of the segments proximate the first one of the segments includes the first human pulse pattern identified in the first one of the segments, and to generate a presence indication when the light information associated with the threshold amount of the segments proximate the first segment includes the first human pulse pattern.

Example methods disclosed herein to perform inventory display auditing include comparing a reference image of an inventory display obtained during a prior audit of the inventory display with a current image captured by a camera to determine whether the current image corresponds to the same inventory display as the reference image. Disclosed example methods also include, when the current image is determined to correspond to the same inventory display as the reference image, identifying a difference region in the current image corresponding to a portion of the inventory display that changed relative to the prior audit. Disclosed example methods further include, while the current image is displayed on a display screen, modifying a characteristic of the current image in the difference region to indicate a change in product inventory in the portion of the inventory display.
