Abstract
A device and method for applying a material to a surface to repair, restore or refurbish at least a portion of the surface. The device has a sensor and one or more applicator nozzles. The device further includes a reservoir for containing a material to be deposited, and a CPU. The method includes providing information from the sensor about the surface to the CPU, which uses the information to identify where the material is to be deposited and/or how much to deposit.
Claims12
An apparatus for applying a composition to a surface to repair, refurbish and/or restore the surface, the apparatus including:
- a. an applicator head comprising a microfluidic die having one or more applicator nozzles;
- b. a reservoir to hold the composition;
- c. a sensor;
- and
- d. a CPU;
- wherein the sensor is configured to sense at least a portion of the surface and provide the CPU with information about the surface, and wherein the CPU analyzes the information from the sensor to identify surface deviations, and the CPU activates the one or more applicator nozzles based on the surface deviations, wherein the sensor is a color sensor and the sensor and the CPU is programmed to identify a predetermined change in lightness value (“ΔLSvalue”) of plus or minus 1.5% of the background lightness (“background L”).
