PORTABLE DATA TRANSMITTING DEVICE, AND SYSTEM AND METHOD FOR MANAGING HEAT STRESS USING THE SAME
First Claim
1. A portable data transmission device comprising:
- a detachable element which is detached from and attached to a user;
a biometric data sensor which is connected to the detachable element, and measures a user'"'"'s biometric data;
an environmental data sensor which measures data of an environment surrounding the user; and
a wireless transmission unit which wirelessly transmits the measured data.

Abstract
A highly precise clock synchronization apparatus in a real-time locating system (RTLS), includes an optical transmitting/receiving unit for receiving a clock information frame from a clock synchronization server, converting the received clock information frame in series-parallel, and transmitting/receiving the clock information data and the clock information; an offset estimation unit for detecting a preamble signal and a clock information signal from he series-parallel converted clock information frame, calculating a phase difference value by comparing the detected preamble signal with the detected clock information signal, and outputting an offset value based on the calculated phase difference value; and a clock synchronization unit for updating a local clock value to a time of the clock synchronization server based on the offset value and the clock information frame.

6. A heat stress management system comprising:
-
a portable data transmission device comprising a detachable element which is detached from and attached to a user, a biometric data sensor which is connected to the detachable element, and measures user'"'"'s biometric data, an environmental data sensor which measures data of an environment surrounding the user, and a wireless transmission unit which wirelessly transmits the measured data; and a monitoring device which wirelessly receives the biometric data and the environmental data from the wireless transmission unit of the portable data transmission device, and converts the received biometric data, the environmental data, and user'"'"'s basic data that is input in advance, into a heat stress estimation value, thereby remotely monitoring the user'"'"'s heat stress. - View Dependent Claims (7, 8, 9, 10, 11, 12)
