| 20100077420 | METHODS AND APPARATUS TO DETECT CARRYING OF A PORTABLE AUDIENCE MEASUREMENT DEVICE - Methods and apparatus to detect carrying of a portable audience measurement device are disclosed herein. An example portable audience measurement device includes a housing; a media detector in the housing to collect media exposure data; an attachment mechanism coupled to the housing to secure the housing to a person; and a sensor to detect a status of the attachment mechanism to enable determination of whether the device is being carried by the person. | 03-25-2010 |
| 20100102981 | METHODS AND APPARATUS TO DETECT CARRYING OF A PORTABLE AUDIENCE MEASUREMENT DEVICE - Methods and apparatus to detect carrying of a portable audience measurement device are disclosed herein. An example portable audience measurement device includes a housing; a media detector in the housing to collect media exposure data; a first status sensor to detect a first distance between the housing and an object at a first time, wherein the first status sensor is to detect a second distance between the housing and the object at a second time; and a distance comparator to generate a first signal indicative of a relationship between the first distance and the second distance to enable determination of whether the device is being carried by a person. | 04-29-2010 |
| 20100169904 | METHODS AND APPARATUS TO ENFORCE A POWER OFF STATE OF AN AUDIENCE MEASUREMENT DEVICE DURING SHIPPING - Methods and apparatus to enforce a power off state of an audience measurement device during shipping of the device are disclosed herein. An example portable audience measurement device includes a housing, a media detector in the housing to collect media exposure data and a packaging sensor to detect a stimulus generated within the package. A packaging detector compares the detected stimulus to a criterion to determine whether the device is located within the package. | 07-01-2010 |
| 20100169908 | METHODS AND APPARATUS TO ENFORCE A POWER OFF STATE OF AN AUDIENCE MEASUREMENT DEVICE DURING SHIPPING - Methods and apparatus to enforce a power off state of an audience measurement device during shipping of the device are disclosed herein. An example portable audience measurement device includes a housing, a media detector in the housing to collect media exposure data and a packaging sensor to detect an environmental condition exterior to the device. A packaging detector compares the detected environmental condition to a criterion to determine whether the device is located within the package. | 07-01-2010 |
| 20100169909 | METHODS AND APPARATUS TO ENFORCE A POWER OFF STATE OF AN AUDIENCE MEASUREMENT DEVICE DURING SHIPPING - Methods and apparatus to enforce a power off state of an audience measurement device during shipping of the device are disclosed herein. An example portable audience measurement device includes a housing, a media detector in the housing to collect media exposure data, and a packaging sensor to receive an audio signal. A packaging detector generates a frequency spectrum of the detected audio signal, determines an energy of a first frequency associated with the generated frequency spectrum, determines an energy of a second frequency higher than the first frequency and associated with the generated frequency spectrum, and compares the difference between the energy of the first frequency and the second frequency to a muffling threshold to determine whether the device is located within a package. | 07-01-2010 |
| 20100274372 | DISPLAY DEVICE ON/OFF DETECTION METHODS AND APPARATUS - Display device ON/OFF detection methods and apparatus are disclosed. An example method disclosed herein to determine whether a presentation device is ON or OFF comprises determining an audio signature based on an audio signal corresponding to an output of the presentation device, comparing the audio signature to a set of reference signatures corresponding to a set of known media content, and determining a result indicating whether the presentation device is ON or OFF based on whether the audio signature matches any of the set of reference signatures. | 10-28-2010 |
| 20100275225 | METHODS AND APPARATUS TO EXPORT TUNING DATA COLLECTED IN A RECEIVING DEVICE - Methods and apparatus to export tuning data collected in a receiving device are disclosed. An example method of collecting audience measurement data comprises collecting tuning data within a receiving device, and modulating an LED associated with the receiving device to export the collected tuning data from the receiving device. | 10-28-2010 |
| 20120011528 | METHODS AND APPARATUS TO DETECT CARRYING OF A PORTABLE AUDIENCE MEASUREMENT DEVICE - Methods and apparatus to detect carrying of a portable audience measurement device are disclosed herein. An example portable audience measurement device includes a media detector carried by a housing to collect media exposure data; a distance comparator to compare a first distance to an object at a first time and a second distance to the object at a second time; and a compliance detector to validate the media exposure data based on the comparison of the distance comparator. | 01-12-2012 |
