    • An electronic display strip is attached to the shelf front of retail shelves, each shelf having an address code assigned through a control computer. Display fields of variable locations and lengths within each display strip are assigned to each product on a shelf through the control computer. Shelf and display field address codes, product information and product price information are transmitted on a continuous or intermittent basis by the control computer through a communications link to signal processors at each display strip. A control circuit for the display strip stores the information in a display memory and energizes the display field matching the display field address code for the product, thereby displaying the product information and product price in the display field.

    • A device for sensing and digitizing a fingerprint from a subject finger comprising a prism, a pixilated illuminating radiation source such as a surface-emitting laser or a radiation source and a LCD affixed to the bottom surface of the prism and providing for the internal illumination, with a plurality of sub-beams, of the contact surface where the finger of the subject is pressed on the top surface of the prism, a photoelectric sensor to detect the sub-beam radiation reflected from the fingerprint valley points, and a lens for focusing the sub-beam radiation on the sensor. The fingerprint ridge contact points do not reflect incident sub-beam radiation. A computer can provide for sequential emission of the sub-beams so that a single cell photoelectric sensor can be used to detect the reflected sub-beams or a multiple cell photoelectric sensor can be used, with each cell corresponding to a particular sub-beam. Reflected sub-beam radiation corresponds to a fingerprint valley point. Non-reflected sub-beam radiation corresponds to a fingerprint ridge point. The fingerprint is converted to a set of binary codes that can be used for imaging or identification purposes.

    • A method and apparatus for separating multiple frequency information signals. This invention provides a method and apparatus for separating a communications signal, which is comprised of multiple component information waves of distinct frequencies, into its component waves for demodulation. The extraction of the component information waves is accomplished by determining the mid-cycle zero crossing points of the component information waves by reference to a reference wave, determining the amplitude of the combined wave at these zero crossing points and generating amplitude equations for each of these zero crossing points. These amplitude equations are solved to determine the amplitude coefficients of the component information waves, thereby extracting the transmitted information.

    • A method and apparatus for single signal, multiple channel digital information transfer through pulses with time slot allocation. The apparatus consists of one or more transmitting devices and one or more receiving devices. Multiple source signals are each allocated a unique time slot between successive synchronization pulses. Digital signals from each source are converted to positive analog information spikes which are combined in their respective time slot with a negative reference spike of uniform magnitude to form an information pulse. The total signal, which consists of successive synchronization pulses interspersed with information pulses for each signal source, each within its allocated time slot, is transmitted to the receivers. Each receiving device extracts the maximum information spike values and the reference spike values for one or more of the signal sources. The information spike values and the reference spike values are converted to digital and a comparison of the transmitted reference spike values with the received reference spike values is used to calibrate the received information spike values for each signal source.
