Protective band to prevent skin damage to drivers

A method of using a solar radiation protective device to protect a driver from solar radiation damage in a vehicle, comprising:

• attaching an armband connected to the solar radiation protective device to an upper arm so that a front panel of a housing of the solar radiation protective device faces a front window of the vehicle and a side panel of the housing faces a side window of the vehicle;
• turning ON an ON/OFF switch located on a button holding wall of the housing;
• receiving, on a liquid crystal display located on the front panel, a first prompt, generated by a microcontroller located within an interior of the housing, to touch a finger to a skin color sensor;
• receiving, on a liquid crystal display, a second prompt, generated by the microcontroller, to enter a sun protection factor (SPF) value;
• wherein the microcontroller includes electrical circuitry, a memory storing program instructions and a processor configured to execute the program instructions to perform the steps of:
• receiving, from a front panel ultraviolet (UV) light sensor, a front window UVI signal;
• receiving, from a front panel infrared (IR) phototransistor, a front window IR signal;
• receiving, from a side panel UV light sensor, a side window UVI signal;
• receiving, from a side panel IR phototransistor, a side window IR signal;
• receiving, from a temperature sensor located on the side panel, a temperature signal;
• receiving, from the skin color sensor, a skin color signal;
• detecting a skin type of the driver based on the skin color signal;
• calculating an exposure time threshold based on the skin type, the SPF, the front window UVI signal, and the side window UVI signal;
• generating a UV exposure warning when an exposure time exceeds the exposure time threshold;
• calculating an updated skin temperature based on the skin temperature signal, the front window IR signal and the side window IR signal;
• and
• generating an IR exposure warning when the updated skin temperature exceeds a maximum skin temperature threshold.

A non-transitory computer readable medium having instructions stored therein that, when executed by one or more processors, cause the one or more processors to perform a method of using a solar radiation protective device to protect a driver from solar radiation damage in a vehicle, comprising:

• receiving an ON signal from an ON/OFF switch located on a button holding wall of a housing of the solar radiation protective device;
• prompting, on a liquid crystal display (LCD), the driver to touch a finger to a color sensor located on a side window panel of the housing;
• prompting, on the LCD, the driver to enter a sun protection factor (SPF) value;
• receiving, from a front panel ultraviolet (UV) light sensor, a front window UVI signal;
• receiving, from a front panel infrared (IR) phototransistor, a front window IR signal;
• receiving, from a side panel UV light sensor, a side window UVI signal;
• receiving, from a side panel IR phototransistor, a side window IR signal;
• receiving, from a temperature sensor located on the side panel, a temperature signal;
• receiving, from a skin color sensor, a skin color signal;
• detecting a skin type of the driver based on the skin color signal;
• calculating an exposure time threshold based on the skin type, the SPF, the front window UVI signal, and the side window UVI signal;
• generating a UV exposure warning when an exposure time exceeds the exposure time threshold;
• calculating an updated skin temperature based on the skin temperature signal, the front window IR signal and the side window IR signal;
• and
• generating an IR exposure warning when the updated skin temperature exceeds a maximum skin temperature threshold.
