摘要： According to aspects of the embodiments, there is provided an apparatus and method to manage the contact of a cleaning blade and a moving surface to increase the useful life of the blade. For example, a cleaning apparatus for a photoreceptor surface comprises a cleaning unit with a blade holder that rotates about a pivot point, a cleaning blade that is coupled to the blade holder and is positioned to chisel excess toner from the photoreceptor surface, and which cleans excess toner from the photoreceptor surface. The apparatus further comprises a sensor that senses the start and the end of an operational procedure, and an actuator that rotates the blade holder about the pivot point to selectively advance or retract the blade during the start-up procedure and the shut-down procedure. After the cleaning surface has begun to move or reached operating speed, blade contact is increased to bring the blade load up to operational level. By making this change to the conventional static cleaning blade, the peak stress at start-up and shut-down is much reduced and cleaning blade life and reliability are much improved.

摘要： A system and method for measuring a substrate edge signal for image sensor phasing. An intermediate transfer substrate edge signal can be effectively mapped by a substrate edge sensor and recorded for at least one complete revolution. A substrate edge signal from an inter-document zone sampled from any region of a substrate in runtime by a process sensor can also be recorded. A comparison or cross-correlation can be applied between the bare intermediate transfer substrate edge signal and the substrate edge signal sensed in the inter-document zone. A cross-correlation algorithm returns a maximum peak value when the two signals are registered in-phase with one another. This information can then be used to register the bare belt process sensor signal and the process sensor signal over the region of interest in-phase with one another. A flat-fielding algorithm can also be applied to the phase-aligned process sensor data to remove artifacts and compensate for substrate (e.g., belt) induced non-uniformities.

摘要： A method and system for achieving accurate segmentation of characters with respect to a license plate image within a tight bounding box image. A vehicle image can be captured by an image capturing unit and processed utilizing an ALPR unit. A vertical projection histogram can be calculated to produce an initial character boundary (cuts) and local statistical information can be employed to split a large cut and insert a missing character. The cut can be classified as a valid and/or a suspect character and the suspect character can be analyzed. The suspect character can be normalized and passed to an OCR module for decoding and generating a confidence quote with every conclusion. The non-character images can be rejected at the OCR level by enforcing a confidence threshold. An adjoining suspect narrow character can be combined and the OCR confidence of the combined character can be assessed.
