Electronic device with environmental monitoring

摘要

An environmental monitoring device that includes an acoustic sensor is described. During operation of the environmental monitoring device, the acoustic sensor provides acoustic data based on measurements of sound in an external environment that includes the environmental monitoring device. Based on the acoustic data and predefined characterization of the external environment, a control mechanism determines if an alarm device, which is separate from the environmental monitoring device, is activated. For example, the predefined characterization may include a location of the alarm device. This location may be specified by: an image of the external environment, a positioning system, a communication network, and/or an acoustic latency in the external environment. Alternatively, the predefined characterization may include an acoustic transfer function of the external environment proximate to the alarm device and the environmental monitoring device. Furthermore, if the alarm device is activated, the environmental monitoring device may provide an alert.

1. An environmental monitoring device, comprising:
an acoustic sensor that, during operation, provides acoustic data based on measurements of sound in an external environment that includes the environmental monitoring device; and a control mechanism, electrically coupled to the acoustic sensor, which, during operation, determines if an alarm device, which is separate from the environmental monitoring device, is activated based on the acoustic data and predetermined characterization of the external environment, and provides an alert if the alarm device is activated, wherein the predetermined characterization includes determined acoustic latency of the external environment, and wherein the predefined characterization specifies a location of the alarm device relative to a location of the environmental monitoring device in the external environment.
