His work has contributed significantly to advancements in technology, particularly in underwater detection systems.
Latest Patents
One of his notable inventions is the Acoustic Doppler detector. This device utilizes an oscillator to generate a fixed frequency ultrasonic output signal. After amplification, this signal drives a transmitting transducer that projects an ultrasonic beam into water. Reflected signals are received by a receiving transducer and preamplified. A chopper multiplies the received signal with the transmitted signal, generating an output signal if a target exists. To determine whether the target is a swimmer, this output signal is band-pass filtered and amplified, then fed to an automatic alarm and a set of headphones. A human operator listening to the headphone output classifies the target and determines the exact bearing.
Another significant patent is the Waveform comparing phasemeter. This electrical circuit measures the phase difference between a pair of input signals by uniformly limiting selected properties of the waveforms describing the input signals. It modulates an output signal based on the duration of contrariety between the unlimited properties of the input signals, effectively eliminating errors in the output signal due to 'jitter.' Various output means produce either a continuous wave analog signal or a digital bit signal depending on the modulation of the output signal.
