  • Patent number: 6444969
    Abstract: A device for sensing and digitizing a fingerprint from a subject finger comprising a prism, a pixilated LED array 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, and a photoelectric sensor to detect the sub-beam radiation reflected from the fingerprint valley points. A sensor lens may also used for focusing the sub-beam radiation on the sensor. A lens wafer may be affixed between the prism and the LED array for focusing the radiation from each LED on its corresponding illumination point on the contact surface. The fingerprint ridge contact points do not reflect incident sub-beam radiation.

  • Patent number: 6255641
    Abstract: 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.

  • Patent number: 6236691
    Abstract: 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.

  • Patent number: 6122323
    Abstract: A method and apparatus for multiple frequency, multiple channel digital information transfer through 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 time slot and a frequency. A continuous synchronizing wave defines the time slots and provides for time slot tracking. Digital signals from each source are allocated a time slot and assigned one of the information wave frequencies in that time slot. The information waves are combined with the synchronizing wave and transmitted to one or more receivers as one signal in each time slot. The manner in which the waves are combined allows the components to be extracted by the receivers largely through the use of curve fitting techniques rather than through the use of filters.

  • Patent number: 5733418
    Abstract: A method and apparatus are provided for sputtering particles from a target as a film on a substrate. The target and substrate are maintained in a main housing in a first vacuum. The target is biased with a first negative voltage to effect a target bias. A plasma is produced in a cathode box spaced from the target, with the plasma being injected between the target and substrate to effect sputtering by bombarding the target with positive ions and liberating target particles for condensing on the substrate to form the film. The cathode box includes a cathode biased at a second negative voltage to effect a cathode bias, and a sputtering gas is supplied adjacent to the cathode for producing the plasma. Plasma production in the cathode box is decoupled from sputtering at the target for increasing sputtering yield and rate. And, the target may be contoured for focussing the sputtered particles on the substrate.

  • Patent number: 5689529
    Abstract: 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 analog information pulses synthesized from a combination of a fundamental frequency wave and a finite number of its harmonics. 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 fundamental frequency and harmonic components through the use of narrow bandpass, high Q filters for each information pulse in its time slot and uses the known algorithm to reproduce the input digital signals.

  • Patent number: 5640422
    Abstract: A method and apparatus for single signal, multiple channel digital information transfer through waves 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 waves. Digital signals from each source are converted to analog information waves having a positive wave segment and a negative wave segment. The ratio of the amplitude of the positive wave segment to the amplitude of the negative wave segment, the positive-to-negative ratio, for each signal source, is a function of the magnitude of the source digital. The sum of the amplitude of the positive wave segment and the absolute value of the amplitude of the negative wave segment, the positive-to-negative offset, is maintained at a pre-set value at transmission.

  • Patent number: 5601141
    Abstract: A batch thermal cycler for large numbers of biological or chemical samples uses n modules each in good thermal contact with the samples, but substantially isolated from one another, thermally and functionally. Each module carries samples on an upper sample plate. The module has a temperature sensor adjacent the samples, an electrical resistance heating element, and a circulating fluid heat exchanger for step cooling. Heating occurs at a point generally between the samples and the source of the cooling. The modules are individually replaceable. O-rings automatically seal fluid and electrical interfaces. An electrical controller has n simultaneous channels that provide closed loop control of the electrical power to each module. As a method, the invention includes at least one modular temperature zone where the temperature is sensed at a point adjacent the samples in that zone. The samples are heated adjacent the sample plate. Cooling is by a step change. The cooling overshoots a set lower temperature.
