Abstract: An advanced telephone dialler has been described, incorporating a fast retrieval and dial telephone directory. The system simplifies the use of the telephone directory by using a single sliding or rotary key for scanning and selection of the name and number to be dialled and one button for speed dialling of the selected number. The name and telephone number of the selected person are simultaneously displayed on a character display and a normal telephone keypad has been used for entering both letters for the name and digits for the number into telephone directory's memory. A short cut dialling has been also provided by simply using the sequential order number of the person to be dialled from the telephone directory's memory. An option has been provided for checking the incoming calls numbers with the telephone directory of the system and not only displaying the name of the calling person and its number if they have been found in directory.

Abstract: A fast position tolerant and economical fingerprint verification algorithm and software implementation is disclosed. The algorithm has very important advantages in comparison to existing fingerprint verification algorithms like minutia extraction or full image analysis based on a series of two dimensional fast Fourier transforms ( FFT's) and two dimensional cross correlation in speed, compactness of the template and finger positioning for verification. It is based on a small “yardstick” pattern being moved inside the image to be verified, and when a match is found the rest of the verification process is started. The yardstick is divided into segments in order to fit different DSP and microcontroller register lengths and structures. The software code implements the algorithm in the most efficient way for utilization on a digital signal processor architecture.

Abstract: An advanced low cost adaptive frame grabber is described. Its main area of application is in fingerprint identification and verification systems, but it could successfully be used in other biometric identification systems, such as facial, iris or eye identification and/or verification systems. The invented framegrabber is also very suitable for all applications in other areas, like medical electronics, car electronics etc., where automatic image enhancement and/or transformation from grey scale to line art is required. The adaptive framegrabber automatically estimates the dynamic range of the acquired image and sets up a proper offset and measurement range for a video analog to digital converter (ADC). It could also be operated in two different modes, in one the image is acquired as a full grey scale image, and in the other--as a line art (black and white) image. Full controls over the image size and resolution are provided.
