Abstract
Abstract An apparatus for reading information marks comprising a strobe light activating or reflecting information marks manually placed on objects or wood products. A camera is used for reading the marks. One or more detectors are used to recognize marks and color. A central processing unit is used to process, solve and interpret character and color recognition. A photo-electric eye or a signal from a control device is used to time the strobe and detector. The information contained in the marks is fed directly to the control system and may be used to generate reports.

Dependent Claim
20 words
The apparatus of claim 1 where said means to time the strobe light is a signal from a control device.
Claim 5
Dependent Claim
13 words
The apparatus of claim 1 where said camera is an RGB color camera.
Claim 6
Dependent Claim
22 words

Claim 9
Independent Claim
126 words
An apparatus for reading information marks comprising: two strobe lights operating simultaneously to activate fluorescent marks on lumber where said strobe lights are on for a short time, such that the movement of the lumber does not affect the reading of the fluorescent marks; two cameras for reading fluorescent marks where one camera responds to red and orange fluorescents and the other camera responds to green and blue fluorescents; a means to time said strobe lights such that a piece of lumber is positioned under said strobe lights and said cameras; means to transfer the fluorescent marks as read by said camera to other devices; means to process, solve and interpret character and color recognition; and means to transfer the solution to other control system devices.
Claim 10
Independent Claim
126 words
An apparatus for reading information marks comprising: two strobe lights operating simultaneously to activate fluorescent marks on lumber where said strobe lights are on for a short time, such that the movement of the lumber does not affect the reading of the fluorescent marks; two cameras for reading fluorescent marks where one camera responds to red and orange fluorescents and the other camera responds to green and blue fluorescents; a means to time said strobe lights such that a piece of lumber is positioned under said strobe lights and said cameras; means to transfer the fluorescent marks as read by said camera to other devices; means to process, solve and interpret character and color recognition; and means to transfer the solution to other control system devices.
Claim 11
Dependent Claim
20 words
