摘要： A signal injecting apparatus which includes a microcontroller for generating a 1024 hertz square wave signal which is supplied through a NAND gate to a field effect transistor. When the transistor is switch on a tank circuit comprising a pair of capacitors and the primary of a signal injector coil starts oscillating and will continue to oscillate when the transistor is switch off. The power level for the signal to the cable is determined by an operator based on the operator inputs from depressing a pair of push button switches. The microcontroller, responsive to the operator inputs from the push button switches, outputs a digital word to a digital-to-analog converter that represents the required power level. The analog output signal from the digital-to-analog converter is supplied to a control loop circuit which adjust the power level by enabling and disabling the NAND gate.

摘要： A method for testing a cable for defective insulation. A user connects one end of each cable conductor to a numbered terminal block. The user measures the insulation resistance between the first and second conductors of the cable using an insulation resistance tester. Next, the user shorts conductors one and two at the terminal block. The user then measures the insulation resistance between the first and third conductors. Measuring the insulation resistance between conductors one and three also measures the insulation resistance between conductors two and three. The user continues these steps until the insulation resistance for all conductors is measured.

摘要： A multi-piston pump is provided which uses microprocessor controlled checkall valves to control flow rate of a fluid at the pump's outlet port. The pump includes nine cylindrical shaped chambers and associated reciprocating pistons which are driven by a cam attached to a shaft. The pump's shaft is coupled to the shaft of a motor which, in turn, drives the pump's shaft and cam resulting in a fluid, such as seawater, filling each of the nine chambers and then having the fluid forced from the chamber by the movement of its associated piston from bottom dead center to top dead center. A pressure transducer which monitors the pressure at the pump's outlet port and a shaft encoder which monitors the angular position of the pump's shaft respectively provide analog signals indicative of the pump's outlet port's pressure and the shaft's angular position. A microprocessor receives these analog signals in a digital form, processes the signals and provides digital pulse signals to either extend or retract the rod of nine solenoids depending upon the pressure at the pump's outlet port. Each of the nine solenoid rods when extended engage a check ball valve within one of the pumps nine inlet passageways allowing the passageway to remain open when the associated reciprocating piston is in a pumping stroke. This allows seawater to be discharged through the inlet passageway maintaining fluid flow at the outlet port at a pressure level which is commensurate with the intended use of the pump.

摘要： A diver navigation system which provides reliable position information to able a diver to locate and when required repair existing underwater devices such as cables, leg moorings and the like. The diver navigation system comprises a synchronous range-range navigation system operating on a repeating timing cycle, which is accurately duplicated in a master transmitter, a slave transmitter and a receiver. Within the master and slave transmitter the timing cycle is subdivided into two equal approximately one second subcycles, the first subcycle being for the master transmitter and the second subcycle being for the slave transmitter. The master transmitter sends out a tone burst signal at the beginning of the first subcycle and the slave transmitter sends out a tone burst signal at the beginning of the second subcycle. Each tone burst signal, in turn, comprises a 34 kilohertz signal followed by a 32 kilohertz signal each of which has a time period of approximately one millisecond. The tone bursts signals travel through water and arrive at the receiver delayed by a time period which is a function of range, temperature, pressure and the velocity of sound. The detection times for travel of the tone burst signals from the master transmitter and the slave transmitter are converted to range data by the receiver using the velocity of sound. The range-range data is then converted to X and Y coordinates by the receiver using a baseline length which is the distance between the master transmitter and the slave transmitter.

摘要： An ultrasonic system for determining the quality of concrete under water hout inaccuracies caused by electromagnetic interference from the ultrasonic generator. An ultrasonic generator applies pulses to the concrete. An ultrasonic detector detects the ultrasonic pulses and produces corresponding signals that are indicative of ultrasonic pulses that have passed through the material. Signal processing circuitry processes the signals to determine the transit time of the ultrasonic pulses through the material. The signal processing circuitry is disabled for a predetermined time after application of each ultrasonic pulse to the material to prevent noise produced by the means for applying ultrasonic pulses to the material from entering the signal processing circuitry and causing spurious measurements.

摘要： A measuring apparatus which accurately locates reinforcing bars in underwater concrete structures such as piers, retaining walls, easements and the like and measures the amount of concrete covering each reinforcing bar. The measuring apparus comprises a probe which generates a magnetic field and which is moved over the surface of the underwater concrete structure under test. When the poles of the magnetic field are in parallel alignment with and directly over a reinforcing bar within the structure a disturbance occurs in the magnetic field with the magnitude of the disturbance being indicative of the depth of concrete covering the reinforcing bar. An electronics module electrically coupled to the probe provides an analog output signal which is indicative of the distance between a reinforcing bar within the concrete structure under test and the probe. This analog signal is supplied to a meter which provides a visual indication of the location of the reinforcing bar and a microprocessor which then calculates the depth of the reinforcing bar within the concrete sructure.

摘要： A measuring apparatus which detects defects in underwater concrete structs by measuring the compressive strength of the structure. The measuring apparatus comprises a rebound hammer which has extending from the nose thereof a plunger. The plunger is pressed against the structure whose compressive strength is being measured forcing the plunger into the rebound hammer's housing which releases a spring driven mass. A resistive film strip which is in electrical contact with the mass detects the maximum rebound of the mass and provides an electrical signal indicative of this maximum rebound. A data acquisition and processing circuit comprising a microprocessor and signal conditioning electronics receives, processes and stores the electrical signals provided by the resistive strip. This circuit includes a peak detection circuit which captures the peak output signal from the resistive strip. The peak detection circuit then interrupts the microprocessor and sends an analog signal proportional to the maximum rebound of the mass to an analog to digital converter which converts the analog signal to a digital data for processing by the microprocessor. The microprocessor then calculates the compressive strength of the underwater concrete structure under test.

摘要： An underwater communications system comprising first and second communications modules which transmit and receive data utilizing infrared radiation. Each module has a transmitter/receiver which converts each received data byte to RS-232 formatted data for transmission to a computer. Each communication module also includes a timer for providing a forty kilohertz pulsed signal to modulation circuitry which passes the pulsed signal through the modulation circuitry when a logic zero is supplied to the modulation circuitry and which inhibits the pulsed signal when a logic one is supplied to the circuitry. That portion of the pulsed signal which passes through the modulation circuitry is provided to a light emitting diode which transmits a pulsed burst of infrared radiation to an infrared light detecting unit within the second communications module. The infrared light detecting unit then provides a logic zero at its output when its receives a pulsed burst of infrared radiation for time period of approximately six hundred microseconds and a logic one when the unit fails to detect a pulsed burst of infrared radiation for a time period of six hundred microseconds.

摘要： An electronic controller for controlling the fill, settle and draw operations of three settling tanks which are used with a reverse osmosis unit. The three settling tanks provide a pair of liquid level input signals which indicate the water level within each of the three settling tanks. A bounce eliminator circuit eliminates oscillations from the input signals, providing at its outputs steady state liquid level signals which are active low. The liquid level signals are supplied to a programmable logic device which has a state machine. The state machine sequentially controls the fill, draw and settle operations of the three settling tanks. The programmable logic device provides logic signals which are active low and which activate fill and draw valves associated with each of the three tanks.

摘要： An apparatus for measuring the length of fiber optic cable being deployed om a winch to an underwater environment. The cable deployment measuring apparatus of the present invention comprises a constant current generator for generating a direct current, a resistor array having a plurality of series connected resistors and a plurality of trip wires with one of the trip wires being connected across each of the resistors. The trip wires which function as short circuits are also attached to the cable at predetermined locations along the length of the cable. When the fiber optic cable is being deployed, each trip wire will break when the location at which the trip wire is positioned is unwound from the winch for deployment in the underwater environment. This, in turn, will cause flow through the resistor array with a resulting voltage drop across the array. A digital volt meter may, for example, be used to measure the voltage drop across the array with the voltage reading provided by the volt meter being indicative of the length of fiber optic cable already deployed.
