CPC Class H04W

One variation of a method includes: in a feed of images recorded at a set frequency by an aerial sensor, detecting a signal generated by a sensor plant configured to generate optical signals indicating presence of a set of stressors; identifying a location of the sensor plant; identifying a user associated with a crop located proximal the location; and flagging the user for recruiting to join a sensor plant platform. The method further includes, during a trial period for the user: in response to detecting a pressure of a first stressor exceeding a threshold pressure at the sensor plant, notifying the user of the first pressure and a first action predicted to reduce pressures of the first stressor; and, in response to detecting a second pressure of a second stressor at the sensor plant, prompting the user to join the sensor plant platform to access information regarding the second stressor.

A connected diagnostic system (CDS) for mobile assets that includes an onboard processing unit and a remote web-based platform that provides a remote view of an onboard display and/or Human Machine Interface (HMI) of the mobile asset. The onboard display and/or HMI can be the mobile asset's own onboard display or an onboard display can be included with the CDS. The onboard processing unit receives data from data sources onboard the mobile asset, such as onboard systems and onboard subsystems, and/or data sources remote from the mobile asset and displays the data on the onboard display, using wired communication channels, and on the remote web-based platform, using wireless communication channels. The onboard processing unit can also receive data from a data acquisition and recording system (DARS) for mobile assets that includes a data recorder.

An IoT switchgear operation system using sound wave communication including: a communication terminal for requesting, from an IoT switchgear via sound wave communication, one or more operations among manager registration, user registration, transmission of a changed password, transmission of a one-time digital key for a user, which is for the user himself/herself to open or close the IoT switchgear, and transmission of a one-time digital key for another person, which is for a terminal of another user to open or close the IoT switchgear; and the IoT switchgear for performing manager registration, user registration, a change of a password, storage of a one-time digital key for a user, and opening or closing of a door by using a one-time digital key for another person, which are requested by the communication terminal via sound wave communication with the communication terminal.
