Abstract: Methods and apparatus for multi-purpose metering are disclosed. An example method includes determining whether a portable device is within a vicinity of a household monitoring system based on detecting an identifier via a first radio frequency (RF) signal, when the identifier from the first RF signal is associated with the portable device, determining whether a second acoustic signal includes the identifier associated with the portable device, deactivating a media detection circuit of the portable device when the identifier is detected via both the first RF signal and the second acoustic signal, and activating the media detection circuit of the portable device when the identifier is detected from the first RF signal and the second acoustic signal is absent.

Abstract: Methods and apparatus for multi-purpose metering are disclosed. An example method includes transmitting a first discovery inquiry message in response to a wakeup timer expiration signal, disabling a media detection circuit of the portable device when a base unit responds to the discovery inquiry message, and enabling the media detection circuit of the portable device when the base unit response to the discovery inquiry message is absent.

Abstract: Methods and apparatus to detect an operating state of a display are disclosed. An example device to detect an operating state of a display includes an optical fiber, an optical-to-electrical converter, and a logic circuit. The optical fiber is optically coupled to a light source of the display. The light energy source is configured to emit light. The optical-to-electrical converter is coupled to the light source via the optical fiber and configured to convert light from the light source into an electrical signal. The logic circuit is coupled to the optical-to-electrical converter and configured to generate an output signal indicative of the operating state of the display based on the electrical signal.

Abstract: Methods and apparatus for multi-purpose metering are disclosed. An example method includes acquiring a rate of data transfer to/from the monitored location and comparing the acquired rate of data transfer to a threshold. The example method also includes setting at least one media monitoring device in a first bandwidth mode when the acquired rate of data transfer exceeds the threshold, and setting the at least one media monitoring device in a second bandwidth mode when the acquired rate of data transfer is below the threshold.
