Embodiment Construction
[0017] Those of ordinary skill in the art should understand that the following description is provided for the purpose of illustration and not for limitation. Those skilled in the art will understand that there are many variations that fall within the configuration of the present invention and the scope of the appended claims. Unnecessary details of known functions and operations are omitted from the current description so that they do not obscure the description of the present invention.
[0018] figure 1 is a schematic illustration of the first aspect of the invention. A user 101 with a cellular phone 105 (not drawn to scale) is located in an outdoor area closest to area A (areas B and C are also shown). The sun 102 and sunlight also emit ultraviolet light. Each zone has a plurality of sensors 115 specifically designed to detect ultraviolet light. For example, US Patent 5,387,798 to Funakoshi et al., which is incorporated herein by reference as background material, discl...

An ultraviolet radiation indicator system includes a wireless telephone adapted communication with a wireless communication network having a positioning system, such as an enhanced emergency services function. A plurality of radiation sensors that sense ultraviolet radiation are arranged in predetermined areas. The radiation sensors are adapted for communication with the wireless communication network. The wireless communication network provides at least an ultraviolet radiation index (UV index) based on readings from the sensors located closest to the wireless telephone, with the UV index being transmitted to the wireless telephone. In the event the wireless telephone is far enough away from the closest sensors to cross a threshold, then the user is sent general information from the Weather Bureau for a particular geographic designation, such as a zip code, city, portion of city, etc. The ultraviolet radiation indicator can provide the UV index to the wireless telephone upon a user request received from the wireless telephone, or the user may subscribe to the surface. Alternatively, the user may receive unsolicited updates for a period of time subsequent to the first request, or when conditions change significantly.
Description
technical field [0001] The present invention relates to detection and warning systems. More specifically, the present invention relates to detection systems for ultraviolet (UV) radiation. Background technique [0002] Health professionals, as well as the general public, are becoming increasingly aware of the damaging effects of prolonged sun exposure on human skin. The ozone layer that is created on the Earth's surface to act as a filter to reduce the amount of ultraviolet light present in sunlight is getting thinner (to the point that there is a hole in the Earth's North Pole). By many standard measures, the amount of harmful rays present in the sun continues to increase, increasing the risk of skin cancer and otherwise aging the skin, causing spots and wrinkles. Excessive exposure to UV light has now been linked to an increased chance of eye damage, particularly cataracts, which is why glasses coated with UV-blocking materials have become very popular. UVB radiation is...
