Lineal length measurement system for timber
First Claim
1. A system for measuring timber carried in a direction of travel by a conveyance medium, said system comprising:
- a sensor configured to sense when a first end of the timber reaches a reference point along the conveyance medium;
an optical distance measuring device configured to be aligned with said conveyance medium in the direction of travel, said measuring device being configured to measure a distance between said measuring device and a second end of the timber; and
a processing device in communication with said sensor and said measuring device, said processing device being configured to calculate a length of the timber between the first end and the second end based upon outputs of said sensor and said measuring device.

Abstract
A system for measuring timber carried in a direction of travel by a conveyance medium includes a sensor for sensing when a first end of the timber reaches a reference point along the conveyance medium. An optical distance measuring device is aligned with the conveyance medium in the direction of travel. The measuring device measures a distance between the measuring device and a second end of the timber. A processing device is in communication with the sensor and the measuring device. The processing device calculates a length of the timber between the first end and the second end based upon outputs of the sensor and the measuring device.

7. A timber measurement system, comprising:
-
a conveyance medium configured to carry the timber in a direction of travel;
an optical sensor configured to sense when a first end of the timber reaches a reference point along said conveyance medium;
a plurality of optical distance measuring devices aligned with said conveyance medium along the direction of travel, each of said measuring devices being configured to measure a distance between said measuring device and a second end of the timber at a respective one of a plurality of levels, the levels being offset from one another in a direction perpendicular to the direction of travel; and
a processing device in communication with said sensor and said measuring devices, said processing device being configured to calculate a length of the timber between the first end and the second end based upon outputs of said measuring devices when said optical sensor senses that the first end of the timber reaches said reference point along said conveyance medium. - View Dependent Claims (8, 9, 10, 11, 12, 13)
