Example methods disclosed herein include accessing a query requesting a metric associated with a number of unique members of an audience of media over an aggregate monitoring interval corresponding to a plurality of component monitoring intervals. Disclosed example methods also include determining respective aggregate interval probability distributions modeling likelihoods of respective monitored individuals being exposed to the media during the aggregate monitoring interval, a first one of the aggregate interval probability distributions for a first one of the monitored individuals being determined by combining parameters of respective component interval probability distributions modeling likelihoods of the first one of the monitored individuals being exposed to the media during respective ones of the component monitoring intervals. Disclosed example methods further include evaluating an audience-level probability distribution determined from the aggregate interval probability distributions to determine the metric to transmit to the computing device in response to the query.

An example apparatus includes a distance matrix generator to determine a number of remapping combinations corresponding to a first and a second household demographic model, generate (a) a first age-based household demographic model and a second age-based household demographic model and (b) a third age-based household demographic model and a fourth age-based household demographic model, generate a first distance matrix corresponding to the first and the third age-based household demographic model, and generate a second distance matrix corresponding to the second and the fourth age-based household demographic model; a distance matrix identifier to determine a first and a second reassignment distance; and a person identification assigner to assign a person identification number of a first person corresponding to the first household to a second person corresponding to the second household based on the first distance matrix or the second distance matrix.

A method for conducting a media consumption study, includes at a processor of a position marker placed in a study site in a vicinity of a fixed media device; receiving a signal broadcast from a personal measurement device; determining signal information of the received broadcast signal, the signal information including identification information of the personal measurement device, and one or more signal characteristics; comparing the one or more signal characteristics to threshold values; and based on the comparison, determining the personal measurement device is in proximity to the fixed media device.

A system and method for sharing an image showing at least one person. The method includes generating at least one signature for the image; determining, based on the generated at least one signature, at least one personal identifier of each of the at least one person, wherein each personal identifier uniquely identifies the respective person; searching, using the determined personal identifiers, for at least one sharing identifier in at least one data source, wherein each sharing identifier indicates information for sharing the image with one of the at least one person; and sending a notification indicating the image using the at least one sharing identifier.

Measuring and tracking user interaction with a television receiver, such as a set top box or cable box. The television receiver may create and display a matrix code that includes temporal information, user identification information, geographic information, and/or a user selection. The matrix code may be captured by a matrix reading device and transmitted to a monitoring entity. Optionally, the matrix reading device may decode the matrix code and transmit associated data to the monitoring entity. The monitoring entity may use the code or data to track and distinguish between user interactions at different points in time.

A TV audience survey system for determining the TV viewing activities of a plurality of individuals in a household includes a master device and multiple tags, each tag assigned to an individual. After an individual logs into the system and starts watching the TV, the master device communicates with the corresponding tag repeatedly to accumulate data representing the individual's TV viewing activities. Such data can be used to determine when the individual stops watching the TV for an extended period of time without logging out of the system and when the household member remains watching the TV after logging or being logged out of the system. The master device then reports the accumulated data to a remote server, which uses the data to determine whether the individual complies with the logging protocol defined by the TV audience survey system and update the TV viewership data associated with this household.

Methods, systems, and vehicles are provided that utilize a communication system that may include infotainment systems and telematics systems along with land network and call center functions to target audio content to an occupant of the vehicle, e.g., the driver or a passenger. The systems, methods and vehicle may seamlessly replace broadcast content segments of broadcast programming with targeted content.

Methods and apparatus to capture images are disclosed. An example device disclosed herein includes an image sensor to observe a first image of a face and a logic circuit. The logic circuit is to determine whether the face in the first image is in a first orientation with respect to the image sensor. When the face in the first image is in the first orientation, the logic circuit is trigger the image sensor to capture a second image of the face, and perform a facial recognition process on the second image, but not on the first image.
