Force - Washington DC

International Classification:

H01J 4702
G01T 1185

US Classification:

2503851

Assignee:

The United States of America as represented by the Secretary of the Air
Force - Washington DC

International Classification:

G01T 122

US Classification:

250370

Abstract:

Appl. No.:

14/299129

Inventors:

Richard J. PETROCY - Carteret NJ, US
John A. CAPPELLI - New Rochelle NY, US

International Classification:

G05B 15/02

Abstract:

A method performed by a control unit in an array of multiple self-addressable control units arranged in at least two dimensions involves obtaining information to be used to determine a self-address, determining a self-address value based upon the information, storing the determined self-address value, based upon the self-address value, specifying first data to be provided to a next self-addressable control unit in a first group of self-addressable control units for a first dimension of the array, providing the first data to the next self-addressable control unit in the first group, based upon the self-address value, specifying second data to be provided to a different self-addressable control unit in a second group of self-addressable control units for a second dimension of the array different from the first dimension of the array, and providing the second data to the different self-addressable control unit in the second group.

Inventors:

Richard Joel PETROCY - Carteret NJ, US
John A. CAPPELLI - New Rochelle NY, US

International Classification:

G09F 13/00
G09F 13/44

Abstract:

A lighting display system is described and has multiple longitudinal tubes, each having a translucent face, the longitudinal tubes being co-aligned in a longitudinal direction, multiple sequentially interconnected base units having thereon at least one luminaire, at least one control unit associated with the base units, and wherein at least some of the base units are configured to self-address.
