Patent attributes
A proximity detection apparatus for avoidance of nearby subjects includes an article, a detector, an alert device and a controller. The article is for a user. The detector is configured to generate a detected value in response to sensing infrared radiation emitted from a subject in a vicinity of the article. The alert device is configured to generate an alert in response to a control signal. The controller is in communication with the detector and the alert device. The controller is configured to set a first predetermined value associated with a proximity condition of an unacceptable proximity range, configured to determine when the detected value exceeds the first predetermined value, and generate the control signal to the alert device to present the alert to inform the user that the subject is within the unacceptable proximity range.
