Abstract: A system for monitoring a live population uses a unit as a local data collection device to derive data on the physical condition of a population member. The unit has a local processor for correlating and storing the physical condition data relative to time and a mechanism for transferring the stored data from the local processor to a remote data collection device. The remote data collection device also receives data relating to the location of the population member relative to time, and analyzes the physical condition and location data for unusual events, providing a signal on the occurrence of an unusual event. The physical condition may be derived from a sensor, which is a non-invasive sensor for measuring pulse rate, temperature and oxygen levels. The location data is provided from a locator incorporated in the unit.

Abstract: A system for monitoring a live population uses a unit (1) as a local data collection means to derive data on the physical condition of a population member (2). The unit (1) has a local processor (6) for correlating and storing the physical condition data relative to time, and means (7) for transferring the stored data from the local processor (6) to a remote data collection means (3). The remote data collection means also receives data relating to the location of the population member (2) relative to time, and analyses the physical condition and location data for unusual events, providing a signal on the occurrence of an unusual event. The physical condition may be derived from a sensor (4), which is a non-invasive sensor for measuring pulse rate, temperature and oxygen levels. The location data is provided from a location means (5) incorporated in the unit (1).
