1. A portable audience measurement device, comprising:
- 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.

Abstract
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.

16. A method of detecting carrying of a portable audience measurement device, comprising:
-
receiving a first reading from a sensor indicative of a first distance between the portable device and an object at a first time; receiving a second reading from the sensor indicative of a second distance between the portable device and the object at a second time; comparing, using a logic circuit, the first and second readings to detect whether the first and second distances are substantially equal; and interpreting a difference between the first and second distances as an indication that the portable device is being carried by a person. - View Dependent Claims (17, 18, 19, 20, 21, 22)

23. A method of detecting carrying of a portable audience measurement device, comprising:
-
determining a first distance between the portable device and an object at a first time and a second distance between the portable device and the object at a second time; determining a difference in distance between the first and second distances; interpreting the difference in distance as an indication that the portable device is being carried based; calculating, using a logic circuit a frequency of the indications that the portable device is being carried for a period of time; and calculating a likelihood that the portable device is being carried during the period of time based on the frequency. - View Dependent Claims (24, 25, 26, 27)
