Title: Thermal imaging apparatus
Inventor: MOORE WILLIAM THOMAS
IPC: H04N3/09
Filed: 1987-12-09
Abstract: Optical means 2, 10 provides a thermal image which is scanned across an array of detectors 4. In a first mode the scan has a wide field of view and low scanning frequency. When the field contains a rapidly moving object, the image is not updated sufficiently frequently and thus a second scanning mode is provided having a smaller amplitude but higher frequency. In the first, wider field mode thermal references 16, 18 are also scanned to provide data enabling differences in the responses of the detector array elements to be compensated. In the narrow field mode, average compensation values are stored, with re-measurement as often as is necessary. <IMAGE>

Patent GB-2225651-A (GB)
Title: Speed control of a robot
Inventor: GOODRIDGE RICHARD JAMES
IPC: G05B19/418
Filed: 1989-10-04
Abstract: In a system for mass producing garments, shaped pieces of fabric (19) are fed through sewing positions (6,7) by gantry robots (1-4). At each sewing position the fabric is fed through the sewing machine at a required speed and with a required orientation by a gripper (10-13) which is moved linearly and rotationally by the robot, but at the sewing machine needle the fabric is moved by the sewing machine itself, in dependence upon the needle speed. The required robot speed and orientation for each operation are stored and are controlled by the system software. However, the actual sewing speed at any instant may not be correct for the programmed robot speed, because the sewing machine may have to reduce its speed for a fault condition, such as the needle overheating. The actual sewing speed is therefore monitored, and the robot speed controller (14-17) is operable, if the actual sewing speed does not correspond to the programmed sewing speed, to modify the actual robot speed, so that   <IMAGE>   <IMAGE>
