Appl. No.:

11/609707

Inventors:

David W. Hudgens - Alexandria VA, US
John McDermott - Alexandria VA, US

Assignee:

ACCU-Spatial LLC - Alexandria VA

International Classification:

G08B 1/08
G05B 23/02
H02H 11/00

US Classification:

34053913, 340 31, 307326

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.

Appl. No.:

11/191589

Inventors:

David Hudgens - Alexandria VA, US

International Classification:

G06F 17/50

US Classification:

705007000

Abstract:

A system and method of context-sensitive, location-based information delivery at a construction site senses the identity and current location of each user, and accesses a variety of databases. Based on a user's identity, the status of various tasks associated with the user, and the user's location, the system intelligently accesses only the information that the user needs at his current location at the current time. The system automatically, wirelessly transmits the information to the user, in the most useful format. The system may additionally observe and track the movement of personnel, equipment, and building materials on the construction site, leading to increased productivity through more effective management. The system may also enforce location-based safety codes.
