Concept Search - What can I type?
For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.
Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.
Image Scanner having Image Quality diagnostics capability with NO operator intervention
ACM (Automatic Consulting Machine) or KIOSK is equipped with various I/O devices. These devices are usually designed so that workload and cost for maintenance is minimized using mechanisms, such as power-on self diagnostics and remote status monitoring via network.
Within I/O devices, image capturing devices have special requirement for image quality and degradation of image quality make those devices completely useless. Still camera for operator identification and image scanner for application form capturing are examples of such devices. As for a camera, image quality check is possible by actually capturing image. Even if there is no operator sitting in the front of the machine, the background image is usually satisfactory for image quality check. As for image scanner, the situation is different. When no operator exists near the machine, no document is put in the scanner, and therefore activating the scanner results in just white image which is useless for image quality check.
The main idea of this invention is to put test pattern on the lower surface of the scanner cover. Any sort of image can be used for image quality check. Standard test pattern for image scanners should be good candidates. The flow of operation is described below.
1. (Preparation) Put test pattern on the lower surface of the scanner cover, which is usually painted in white. The...
