Abstract
The invention provides a carry-on chronometric device having UV detection and warning functions, comprising a housing for defining a containing space which contains a control circuit, a display unit, a memory unit, and an input unit, a chronometric unit, a battery, and an UV detector unit and a time-varying intensity accumulator whereby the ambient UV intensity and its accumulating intensity can be detected and displayed at any time and any place for reference so as to achieve an efficacy of warning.
Claims4
A carry-on chronometric device, for detection of UV ray and display of time and data, said device comprising:
- a housing, for defining a containing space, which contains:
- a control circuit unit, for processing the time and the data, and controlling action of each member of the device, based on a control signal;
- a display unit, for displaying the time and the data;
- a memory unit, for storing the data;
- an input unit, for input of the control signal to the control circuit unit to process the data and control the action of each member of the device based on the control signal;
- a chronometric unit, for providing the time;
- a battery, for providing a working voltage to each member;
- an UV detector unit, for detecting an intensity of the UV ray;
- and
- a time-varying intensity accumulator, for accumulating the intensity of the UV ray and calculating an accumulated dose of the intensity, and for output of the intensity and the accumulated dose to the display unit for displaying and to the memory unit for storage.
