Abstract: Pressurized gas turbine engine with efficiency enhanced by an electrothermodynamic power convertor. The turbine has peripheral nozzles which are supplied with pressurized gas or pressurized liquid by internal nozzle gas ways. Pressurized liquid is flashed by the nozzles. The electrothermodynamic power convertor has a collector plate which envelopes the turbine engine expansion chamber and a charged screen which is positioned radially between the gas nozzles and the collector plate. Collector plate insulation is affixed between the collector plate and the walls of the expansion chamber.

Abstract: A pressurized gas turbine engine is disclosed which utilizes a new turbine design. Pressurized gas is supplied by nozzle gas ways in the turbine to gas nozzles affixed to the perimeter of the turbine. The gas nozzles may be recessed in the turbine perimeter or extend from the turbine perimeter. The gas nozzles may be equipped with gas exit cones to enhance the efficiency of the nozzles. The axis of the nozzles have an oblique angle with the direction of rotation of the turbine. Pressurized gas is supplied to the nozzle gas ways through one or more shaft gas ways in the turbine shaft, or is supplied through engine gas ports in the front wall of the turbine engine to gas supply zones which are hydraulically separated by seal rings on the front face of the turbine, each gas supply zone being hydraulically connected to one or more nozzle gas ways.

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.

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.

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.

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.

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.

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.

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 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.
