Construction hard hat having electronic circuitry
First Claim
1. A method of monitoring the activities of workers on a construction site, comprising:
- placing a plurality of spaced sensors on the construction site and dividing the construction site into a plurality of sectors and monitoring each sector of the construction site with at least one sensor;
issuing each worker a construction hard hat having electronic circuitry formed as a part of the hard hat and storing personal information in the electronic circuitry that uniquely identifies a worker;
when one or more workers are on the construction site, establishing a wireless communication link between a respective sensor and the electronic circuitry of a respective construction hard hat worn by a worker;
after a communication link has been established between a sensor and an electronic circuitry of a particular construction hard hat, reporting to a monitoring station;
a. personal information uniquely associated with the electronic circuitry of the construction hard hat, andb. location information that identifies the sector of the construction site where the construction hard hat is located;
associating the reported personal information with the reported location information;
generating a virtual map of the construction site and associating each sector of the construction site with a corresponding zone of the virtual map;
associating each zone of the virtual map with sector specific information stored in a database where the sector specific information includes sector authorization information associated with each sector;
accessing the virtual map and identifying the zone of the virtual map corresponding to the associated personal information and location information reported to the monitoring station; and
retrieving the sector authorization information associated with the identified zone of the virtual map and comparing the reported personal information with the retrieved sector authorization information and based on that comparison, determining whether the worker wearing the construction hard hat from which the reported personal information was received is authorized to be in a corresponding sector of the construction site.

Abstract
Personnel activity at a construction site is tracked using electronic circuitry included in hard hats worn by personnel at the site. According to one embodiment, activity at a construction site is monitored by processing personal information directly or indirectly received from electronic circuitry formed as part of one or more hard hats worn by personnel located at the construction site. The personal information is uniquely associated with individual ones of the personnel. One or more messages are generated based on the personal information received from the electronic circuitry and personnel location. For example, the messages may warn particular personnel that they have entered an unauthorized area at the construction site. Optionally, personnel activity may be periodically monitored and reported.

17. A method of monitoring activity at a construction site, comprising:
-
retrieving, from electronic circuitry formed as part of a construction hard hat worn by a worker located at the construction site, at least one of trade or qualifications information associated with the worker; reporting the retrieved trade or qualifications information to wireless sensors located in multiple sectors throughout the construction site when the hard hat electronic circuitry comes within signal range of one of the sensors as the worker moves about the construction site; determining whether the worker accesses an unauthorized area at the construction site based on the reported trade or qualifications information and the location of the sensors that receive the reported trade or qualifications information from the hard hat electronic circuitry; and sending a message to the construction hard hat if the worker accesses an unauthorized area;
