Latest Patents

Hannes Ruf's latest patents include a camera-based code reader and a method of reading optical codes. The first patent describes a camera-based code reader equipped with an image sensor that detects image data containing an optical code. This device features a memory for storing image data, a first processing unit for transmitting the image data from the image sensor to the memory, and a second processing unit designed for decoding the stored image data to read the code content. The first processing unit is also capable of performing auxiliary functions, such as reading back image data from memory and writing pre-processing results back to it. The second processing unit can invoke these auxiliary functions as needed to assist in decoding.

The second patent focuses on a camera-based code reader that reads optical codes on objects in relative motion. This device utilizes a linear image sensor to capture image lines and includes a control and evaluation unit with a first pre-processing unit and a further processing unit. The first pre-processing unit reads image lines sequentially during relative movement, rescales them with a zoom factor, and forwards them to the further processing unit, which is responsible for extracting the optical code from the image lines.
