| 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 |

| 20080271065 | Methods and Apparatus for Indirect Illumination in Electronic Media Rating Systems - Methods and apparatus for indirect illumination in electronic media rating systems are disclosed. A disclosed electronic media rating system comprises an audience image detection system and a non-visible light source to provide indirect illumination of an audience member. | 10-30-2008 |
| 20090055854 | METHODS AND APPARATUS FOR COOPERATOR INSTALLED METERS - Methods and apparatus for cooperator installed meters are disclosed. An example method includes receiving audience information, configuring the audience meter based on the audience information, placing the audience meter in a sleep mode, and shipping the audience meter to a location associated with the audience information. | 02-26-2009 |
| 20100045972 | METHODS AND APPARATUS FOR INDIRECT ILLUMINATION IN ELECTRONIC MEDIA RATING SYSTEMS - Methods and apparatus for indirect illumination in electronic media rating systems are disclosed. A disclosed example method includes reflecting infrared light off of a room ceiling to indirectly illuminate the audience member, receiving reflections of the indirect illumination off of the audience member, blocking visible light prior to receiving the reflections of the indirect illumination off of the audience member, and processing the received reflections to detect the audience member. | 02-25-2010 |
| 20100325647 | METHODS AND APPARATUS FOR INDIRECT ILLUMINATION IN ELECTRONIC MEDIA RATING SYSTEMS - Methods and apparatus for indirect illumination in electronic media rating systems are disclosed. A disclosed example method to detect an audience member includes reflecting non-visible light off of a room surface to indirectly illuminate a first portion of the room, receiving reflections of the indirect illumination, processing the received reflections to determine whether an audience member is present in the illuminated portion of the room, and when the audience member is not detected, adjusting a source of the non-visible light to illuminate a second portion of the room. | 12-23-2010 |
