Abstract

Alarm System for Solar UltraViolet Causing Skin Diseases(ASSUV) Abstract Because of the holes in the Ozonosphere near polars of the earth, skin diseases caused by solar ultraviolet, such as cancer, are becoming big threats to sun-bathers. This invention is made to let sun-bathers enjoy sun shine without worry. It is a device which calculates how much solar ultraviolet one has already received, and gives alarm when too much solar ultraviolet in a certain period has been received.

Description

Specification This invention relates to the alarm system for detecting the Solar UltraViolet ~referred to as Solar-UV hereafter) and its accumulation which are harmful to human skin and may cause skin diseases such as skin cancer.
It has been proved medically that the solar-UV light can lead to various skin diseases, especially skin cancer. The induction of these skin diseases (including skin cancer) is caused by the accumulation of the solar-UV light everyday.
When the accumulation of solar-UV increases up to a certain value, the skin diseases may take place. This invention is intended to warn the accumulation of the solar-UV light on the userY' skins. When the users are working in the sun or/and taking the sun bath, or/and enjoying the sunshine lying on beaches, users' yards, gardens, they take this .~ ' ' . ~ ; .

1nvented device (ASSUV) to -test the accumulation of -the solar-UV light, ASSUV will alarm the users not -to be in the sun con-tinuously any more to avoid causing skln diseases.
This invention is a creative and intensive idea which combines the receiving of -the solar-UV light, solar-UV
calculating, memorizing, accumula-ting and alarming and indicating toge-ther. Although there are ultraviolet detectors used in the condition of high tempera-ture ovens to detec-t the ul-traviolet light and pro-tect the health of workers who are working in -this surroundings, there is no commercial alarm system for protecting the human skins and health in -the solar-UV light.
This ASSUV iS very easy to use. When the users are in the sun light, switch on the ASSUV, the skins of users and the ASSUV simultaneously feel the solar-UV light. When the accumula-tion of the solar-UV 1ight increases to a value harmful to human skins and may cause skin diseases (including skin cancer), The ASSUV alarms the users to stop taking the sun bath today, and the ASSUV can record the total accumulation of the solar-UV light and tell the users not to be in the strong solar light -too long.
This invention is to detect and accumulate the strength of the solar-UV light, rather -than other lights. Fig.1 shows the block diagram of working process of the ASSUV. Fig.2 gives the ~hematic circuit of the A~SUV.
Figure 1 shows the six stages of the ASSUV. In the first stage, the solar-UV is being detected by a narrow band solar-UV sensor circuit with a spectral range of 300 to 400 nm. This stage transforms the solar-UV strength into a voltage signal. The second stage uses a high input impedance circuit to isolate -the first stage from the other circuit, 2~016~

and gives a low output impedance to provide enough power to drive the following circuit. The third stage of -the ASSUV is an integration circuit which accumulates the solar-UV
strength along -the time. This accumulation is used as the input signal to Schmitt trig~ers which is the four~h stage of the ASSUV. The output slgnal of the trigger is amplified and used to drive an alarm and a memory which is the final stage of the ASSUV.
In Figure 2, Rl and the Zener Diode provide a stable voltage source for the solar-UV sensing and the Schmitt triggers, which is critical for the accurate sensing and triggering. The phototransistor and R2 transform -the solar-UV strength into a voltage signal. A high input impedance isolator consisting of Pl and R~, isolates the solar-UV
sensing ircuit from the other circuit and passes on the solar-UV strength signal to a phase inver-tor which consists of OP2, ~ and Rs~ An inverse phase integrator consisting of OP3, ~ and C accumulates the solar-UV strength signal. Rg passes on this integral signal to two Schmitt triggers STI
and ST2 cascaded together. When the solar-UV strength is accumulated to a pre-set level (adjustable by adjusting Rs)~
the first trigger STI gives a low voltage signal to the second trigger ST 2 and S~ outputs a high voltage signal.
This high voltage signal is power amplified by OP4, ~0 and ~1~ and is used to drive an alarm and a memory. A power indicator consists of R7, ~, LED, ST3 and ST4. When a user turns on the ASSUV, the LED lights up indicating the beginning of the solar-UV accumulation, if the LED does not light up, it means that the batteries have no enough power to let the whole circuit work accurately, and should be replaced. The power switch is configured such that when the ASSUV is turned off, the capacitor C is discharged immediately.
