Methods, systems, and apparatus to synchronize actions of audio source monitors
First Claim
1. A method to improve audio data overlap and matching accuracy between a base unit and an audience monitor, comprising:
- initiating a delay period having a first duration on the base unit and the audience monitor, the delay period initiated in response to the base unit sending an acknowledgement signal to the audience monitor, the acknowledgment signal being in response to a radio frequency (RF) initialization signal received by the base unit from the audience monitor at a first time;
determining, when the first duration expires at a second time, if the audience monitor is still processing the acknowledgement signal; and
incrementing the delay period to a second duration to improve audio data overlap and matching accuracy between the base unit and the audience monitor when the audience monitor is still processing the acknowledgement signal after the first duration expires, the second duration based on an increase of the difference between the first time and the second time.

Abstract
Systems, methods, articles of manufacture and apparatus are disclosed to align actions of audio source monitors. An example method disclosed herein includes invoking an audience monitor to transmit a radio frequency (RF) initialization packet to a base unit, receiving an indication that the base unit has received the RF initialization packet at a first time, and invoking the base unit to transmit an RF acknowledgement packet to the audience monitor. The example method also includes receiving an indication that the RF acknowledgement packet is received by the audience monitor and waiting for an end to a delay period having a first value, identifying whether the audience monitor has finished processing the RF acknowledgement packet when the delay period ends at a second time, and incrementing the delay period to a second value when the audience monitor is still processing the RF acknowledgement packet and the delay period has ended.

8. An apparatus to improve audio data overlap and matching accuracy between a base unit and an audience monitor, comprising:
-
a test manager to initiate a delay period having a first duration on the base unit and the audience monitor, the delay period initiated in response to the base unit sending an acknowledgement signal to the audience monitor, the acknowledgement signal being in response to a radio frequency (RF) initialization signal received by the base unit from the audience monitor at a first time, the test manager to determine, when the first duration expires at a second time, if the audience monitor is still processing the acknowledgement signal; and a delay period adjuster to increment the delay period to a second duration to improve audio data overlap and matching accuracy between the base unit and the audience monitor when the audience monitor is still processing the acknowledgement signal after the first duration expires, the second duration based on an increase of the difference between the first time and the second time. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. An article of manufacture comprising instructions which, when executed, cause a machine to at least:
-
initiate a delay period having a first duration on a base unit and an audience monitor, the delay period initiated in response to the base unit sending an acknowledgement signal to the audience monitor, the acknowledgement signal being in response to a radio frequency (RF) initialization signal received by the base unit from the audience monitor at a first time; determine, when the first duration expires at a second time, if the audience monitor is still processing the acknowledgement signal; and increment the delay period to a second duration to improve audio data overlap and matching accuracy between the base unit and the audience monitor when the audience monitor is still processing the acknowledgement signal after the first duration expires, the second duration based on an increase of the difference between the first time and the second time. - View Dependent Claims (16, 17, 18, 19, 20)
