System and method for sending a packet with position address and line scan data over an interface cable

Abstract

A system and method for sending a packet with a position address and line scan data from a first device over a 1394 interface to a second device. The present invention loads a camera, an illuminator, and a microprocessor with set-up instructions and a start pulse. The camera captures a line-by-line image of an object placed on the surface of a sliding prism. Position data, corresponding to the captured line-by-line image, is logged as the position address. The position address is combined with the line-by-line image to form a packet. The packet is sent to the second device for processing and viewing the image.

AI Technical Summary

Benefits of technology

"The present invention is a system and method for interfacing fingerprint images from an identification system to a PC. This is done through a high-speed serial bus called a 1394 interface, which allows for quick data transfers. The invention uses an off-the-shelf PC and a camera to capture line-by-line images of an object placed on a sliding prism. The position data is then combined with the image to form a packet, which is sent to the PC for processing and viewing. The invention provides a cost-effective and flexible way to process and view fingerprint images, and also allows for easy replacement of malfunctioning PCs."

Problems solved by technology

The custom-made consoles are expensive.

Custom-made consoles are also burdened with high maintenance costs.

When the console malfunctions, the entire system is inoperable.

This can sometimes be a lengthy process.

During such maintenance periods, tenprint records cannot be produced.
