Latest Patents
One of his latest patents is titled "Dynamic management and transmissions of error notification and configuration data for printing and paper handling devices." This invention allows a printer to store management or device configuration data in a memory unit. The printer retrieves this data and transmits it to a printer client device, which uses it to provide appropriate error messages. This innovation simplifies the installation process by eliminating the need for the printer driver to be pre-configured with all possible error management data.
Another significant patent is the "Method and apparatus for finding media top-of-page in an optical image." This system involves sensing the leading edge of a document in an imaging scanner by detecting a shadow cast by the edge when exposed to a light source. The shadow is sensed by a photo sensor array, which sends a signal to a microprocessor to initiate image scanning. This method enhances the accuracy of document processing by adjusting the contrast sensitivity of the photo sensor array.
