Abstract
A technique for supplying power from a battery to a transmitter included as part of an insert in a magazine which is used to monitor magazine readership. A switch in the insert is open when the magazine is closed to break the circuit to the transmitter. However, the switch is closed when the magazine is opened. Current is then supplied to the transmitter which emits an identification signal indicative of the magazine being read.

A system for surveying the readership of a designated magazine by individuals selected as test subjects, comprising:
- a transmitter unit suitably sized for unobtrusive attachment to a copy of said designated magazine and including a power source, a transmitter means connected to said power source for emitting an identification signal which is unique to said designated magazine, and switch means which is closed to supply power from said power source to said transmitter means when said magazine copy is opened;
- and
- a receiver unit adapted to be worn by each of said selected individuals and including detecting means for responding to said identification signal to generate a control signal, memory means for storing a signal representative of each detected occurrence of said control signal, and a power source connected to said detecting means and said memory means.
A method for surveying the readership of a designated magazine by individuals selected as test subjects, comprising the steps of:
- attaching a transmitter to each copy of said designating magazine;
- supplying electrical power to said transmitter in response to said magazine copy being opened;
- emitting from said transmitter an identification signal unique to said designated magazine;
