Latest Patents

Hamer's latest patents include a method and device for scanning a radiation-sensitive layer of a rotating carrier. This innovative method utilizes a radiation beam directed towards the carrier by an optical system that is radially movable. The technology involves a velocity-pulse generator that produces clock pulses proportional to the angular velocity of the carrier. Additionally, a clock generator creates clock pulses of constant frequency. The system ensures that the angular velocity of the record carrier is controlled to maintain a constant average of the sum value, allowing for a consistent linear scanning velocity.

Another significant patent involves a method and apparatus for scanning a rotating optical disc record carrier. This invention also employs a radiation beam to form a scanning spot on the carrier, with the scanning being maintained at a constant linear velocity. The technology includes an accumulator that is incremented and decremented based on velocity and clock pulses, respectively. This ensures precise control over the scanning process.
