Abstract: Methods of operating a system of nodes are provided. A method of operating first and second nodes that are in a system of nodes includes processing first data from a first plurality of sensors of the first node. The method includes controlling a first digital display of the first node in response to the processed first data. The method includes uploading the processed first data from the first node via the Internet. The method includes processing second data from a second plurality of sensors of the second node. The method includes controlling a second digital display of the second node in response to the processed second data. The method includes uploading the processed second data from the second node via the Internet. Each of the first and second nodes is attached to a utility pole, a light pole, a kiosk, or a motor vehicle. Related systems are also provided.

Abstract: Power cords are provided. A power cord includes measurement circuitry configured to measure electrical energy consumption by an apparatus that is connected to the power cord. The power cord also includes first transceiver circuitry configured to transmit data regarding the measured electrical energy consumption to second transceiver circuitry that is spaced apart from the power cord. Related hardwired apparatuses and methods are also provided.

Abstract: Portable electronic devices are provided. A portable electronic device includes a weather sensor and a digital display. Moreover, the portable electronic device includes a vibrating motor and/or a buzzer. The digital display is configured to display a target level of liquids to be consumed by a user of the portable electronic device, in response to detection by the weather sensor of a weather condition.
