Device to monitor distance between people

摘要

The device to monitor distance between people measures a pre-defined distance between a first person and other persons, and alerts the user when the pre-defined distance has been breached or violated for more than a pre-determined time. Intended to protect a first human from the deleterious effects of radiation (nuclear) associated with a second human, but useful in other circumstances, the device is designed to detect the presence of a first person within a protective radius of one to two meters of a second person by pairing the combination of one heat sensor with one distance sensor. In the event the first person is within that radius for the predetermined time, the device will alert the user of that circumstance. Alert feedback mechanisms can include an acoustic audible signal, a visible signal, a vibratory signal, or phone notification.

主权项

1. A wearable device to monitor distance between people, comprising:
a belt worn by a user; a distance sensor; a thermal sensor, wherein the thermal sensor is disposed a predetermined distance from a center portion of the belt, the center portion of the belt being in angular alignment with an imaginary midline extending forward from a navel of the user, the imaginary midline dividing a body of the user exactly into left and right side, further wherein the at least one distance sensor is on the same side of the wearer's body as the thermal sensor and more distal from the imaginary midline than the thermal sensor; at least one annunciator; and a microcontroller connected to the distance sensor, the thermal sensor, and the at least one annunciator, the microcontroller having software stored and executable thereon, the software including:
means for determining when an object is within a predetermined distance from the distance sensor in response to signals received from the distance sensor;means for determining whether the object is another person in response to signals from the thermal sensor corresponding to the object's temperature; andmeans for actuating the annunciator to generate an alert when the object is another person within the predetermined distance.
