Methods, systems, and apparatus to calculate distance from audio sources
First Claim
1. A method to reduce battery consumption of a portable audio collecting device, comprising:
- transmitting a first radio frequency (RF) signal from the portable audio collecting device to prompt a reference audio collecting device to begin collecting audio samples from an audio source at a first time, the audio source being closer to the reference audio collecting device than to the portable audio collecting device;
initiating a dwell period in response to the first RF signal to reduce battery consumption of the portable audio collecting device by preventing the portable audio collecting device from collecting audio samples from the audio source at the first time, the dwell period being based on a distance between the portable audio collecting device and the reference audio collecting device; and
when the dwell period expires, prompting the portable audio collecting device to collect audio samples from the audio source at a second time.

Abstract
Systems, methods, articles of manufacture and apparatus are disclosed to calculate distance from audio sources. An example method disclosed herein includes transmitting a first radio frequency (RF) signal to prompt a reference audio collecting device to begin collecting audio samples at a first time, initiating a dwell period in response to the first RF signal to reduce battery consumption of a portable audio collecting device by preventing the portable audio collecting device from collecting the audio samples at the first time, and when the dwell period expires, prompting the portable audio collecting device to collect the audio samples at a second time.

10. An apparatus to reduce battery consumption of a portable audio collecting device, comprising:
-
a radio frequency (RF) transmitter to transmit a first RF signal from the portable audio collecting device to prompt a reference audio collecting device to begin collecting audio samples from an audio source at a first time, the audio source being closer to the reference audio collecting device than to the portable audio collecting device; and a timer to initiate a dwell period in response to the first RF signal to reduce battery consumption of the portable audio collecting device by preventing an audio sensor of the portable audio collecting device from collecting audio samples from the audio source at the first time, the dwell period being based on a distance between the portable audio collecting device and the reference audio collecting device, the timer to prompt the portable audio collecting device to collect audio samples from the audio source at a second time when the dwell period expires. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A computer-readable storage device or storage disk comprising machine-readable instructions that, when executed, cause a machine to at least:
-
transmit a first radio frequency (RF) signal from a portable audio collecting device to prompt a reference audio collecting device to begin collecting audio samples from an audio source at a first time, the audio source being closer to the reference audio collecting device than to the portable audio collecting device; initiate a dwell period in response to the first RF signal to reduce battery consumption of the portable audio collecting device by preventing the portable audio collecting device from collecting audio samples from the audio source at the first time, the dwell period being based on a distance between the portable audio collecting device and the reference audio collecting device; and when the dwell period expires, prompt the portable audio collecting device to collect audio samples from the audio source at a second time. - View Dependent Claims (20, 21, 22, 23, 24)
