Abstract: One or more processors determine whether a hazard that is detected by a first mobile device exists based on data received from at least one second mobile device. The second mobile device is within a proximity to the first mobile device, which is determined based on a type of the hazard. One or more processors respond to a determination that the hazard does exist by determining a course of action. The course of action is configured for a user based on at least one attribute of the user. One or more processors send the course of action to the first mobile device.

Abstract: The flow of a fluid such as water is controlled through an outlet by detecting sound within an environment at a first time and generating a first profile based upon the content of the sound detected at the first time. The flow of the fluid is further controlled by detecting sound within the environment at a second time and generating a second profile based upon the content of the sound detected at the second time. The flow of the fluid is still further controlled by comparing the second profile with the first profile and controlling a control valve to shut off a supply of the fluid exiting a tap based upon the results of the comparison.
