Abstract: Disclosed are various embodiments for data transmission from speakers using magnetic flux coupling. A speaker driver of a first device transmits a magnetic flux signal encoding configuration information. A magnetic flux detector of a second device receives the magnetic flux signal. A processor of the second device demodulates the magnetic flux signal to recover the configuration information. At least one operational parameter of the second device is configured using the configuration information.

Abstract: Disclosed are various embodiments for networked sensor devices. In one embodiment, a networked sensor device is configured to obtain sensor readings from one or more sensors and then store the sensor readings in an email server by way of a wireless or wired network. In one embodiment, a client is configured to obtain one or more reporting emails generated by a networked sensor device, extract data from the reporting email(s), and render a user interface that presents the data extracted from the reporting email(s), where the data includes sensor readings generated by the networked sensor device.
