Abstract: A mobile device that includes an input device, an output device, and an electronic processor connected to the input device and the output device. The electronic processor is configured to receive, from the input device, information about a disinfectant and set a threshold time, a threshold activity level, or both the threshold time and the threshold activity level based on the information about the disinfectant. The electronic processor is also configured to track a passage of time, an activity level, or both. If the passage of time is greater than or equal to the threshold time, the activity level is greater than or equal to the threshold activity level, or both then the electronic processor is configured to output a user notification, via the output device.

Abstract: The present invention relates to devices for dispensing and mixing multi-component materials, in particular for viscous fluid materials. The device is adapted for dispensing multi-component compositions that are kept separate prior to use and that are also typically mixed prior to use to properly combine the constituents in order to form an active and/or working composition. In one embodiment, a device is adapted to contain at least one vessel containing a material prior to use. The device also includes a mechanism for evacuating the at least one vessel and a mechanism for mixing at least one material prior to use. The material may contain multiple constituents in one vessel or more than one vessel.
