    Abstract: Provided is a graphical user interface for programming an embedded device and systems and methods of use thereof. The system for programming an embedded device using a graphical user interface (GUI) comprises the GUI, a processor, and a database. The embedded device includes one or more light sources. The GUI provides control elements associated with the light sources. The processor is configured to receive settings associated with the light sources via the control elements, the settings defining a lighting pattern of the light sources. The control elements include at least actuation, color, and brightness control elements. The processor can convert the settings into configuration data, which is transmitted to the embedded device and decoded by the embedded device. As a result of the decoding, the embedded device is set to generate the lighting pattern based on the configuration data.

  • Patent number: 9354574
    Abstract: A method of controlling performance of auto color registration (ACR) of a color image forming apparatus, and an image forming apparatus using the same are provided. The method of controlling performance of ACR includes forming a composite black image on a transfer belt, sensing the composite black image by using a sensor, measuring the sensed composite black image, and performing ACR correction when a measured width of the composite black image is greater than a previously set value. Accordingly, it is possible to prevent unnecessary performance of ACR control when no color misregistration has occurred. In this way, ACR control is performed in as short a time as possible so that performance of the image forming apparatus may be improved. Also, it is possible to prevent waste of ACR performance time and life span reduction of a driving source for ACR.
