Wearable transponder alert and monitoring system

A wearable personal safety device comprising:

• a housing unit having skin contact and including a radio frequency transponder configured to:
• receive, from a mobile communication device, an initiating signal including a unique user identifier and establish a connection therewith, the transponder being configured to detect biometric and physiological parameter values of the skin,
• memory configured to store data indicative of the detected biometric and physiological parameter values,
• a rechargeable battery, and
• a processor configured to, in response to one of the detected biometric and physiological parameter values not meeting a corresponding threshold, cause the transponder to send to the communication device a request, including the unique identifier, to issue a personal emergency alert.

A wearable device comprising:

• a housing unit including a radio frequency transponder configured to initiate detecting biometric parameter values of skin proximate to the housing unit in response to receiving an initiation signal including a unique user identifier from a mobile communication device,
• memory configured to store data indicative of the detected biometric parameter values,
• a rechargeable battery, and
• a processor configured to, in response to several values not meeting corresponding thresholds, send to the communication device a request to issue a personal emergency alert.

A personal safety system comprising:

• a mobile communication device including a wireless radio frequency antenna;
• and
• a wearable device including a housing unit proximate to the skin, a transponder configured to establish communication with the communication device to receive interval signals therefrom and detect biometric parameter values of the skin,
• a rechargeable battery, and
• a processor configured to, in response to each interval signal, cause the transponder to send to the communication device a corresponding return interval signal including the detected biometric values, such that the communication device issues a personal emergency alert when the communication device fails to receive the return interval signal including the values.
