Abstract: A low-power, fully self-contained fingerprint capture, enrollment and verification method and device (100). The device includes a logic unit (110), a memory (120), a fingerprint sensor (130) and an interface (150) to an external unit (140). Included in the memory is a program (126) that includes a sensor data capture module (200), an image processing module (202), a minutia extraction module (204), a template creation module (206), a template compare module (208), and a database (210). The processes for capturing, enrolling and verifying a fingerprint are designed to be minimally computationally intensive. This allows implementation of these processes in a portable, battery-powered unit using hardware with limited memory and computing capability, or implementation in a PC with substantial performance advantages relative to known fingerprint capture, enrollment and verification processes and devices.

Abstract: A remote control system for providing information to an electronic apparatus such as a PC, Net computer or video game. The system includes a remote controller for generating an IR signal containing information usable by the apparatus, including cursor position information, select commands and other information. The system also includes a primary controller that is connected to the electronic apparatus typically, but not necessarily, by a cable. The primary controller includes a secondary controller having a movable element. The secondary controller generates relative position information based on the position of the movable element. The primary controller also receives the IR signal from the remote controller, converts this signal into electronic form, and then provides this signal to the electronic apparatus.
