Patent EP-0605956-A1 (EP)
Inventor: MARCHETTO ROBERT FRANK
IPC: H04H20/67
Filed: 1993-11-24
Abstract: A method and apparatus provide an equalization time delay to synchronize a plurality of paging transmitters in a simulcast paging system. A delay equalization circuit (41) appropriate for use with an analog input signal includes a coder/decoder (CODEC) (50) and a digital signal processor (DSP) (58). An analog input signal is digitized or sampled by an analog-to-digital converter (ADC) in the CODEC, producing corresponding digital values that are input to the DSP. The DSP employs a selected finite impulse filter to interpolate between the sampled digital values from the CODEC to provide enhanced resolution in delaying a signal output that is output. The DSP determines a major sample index and an interpolated filter index to achieve the desired equalization time delay. These variables define two delay intervals that are combined to provide the required equalization time delay. As each sampled digital value is produced, the delayed value is output and converted by a digital-to-analog converter (DAC) 54 in the CODEC to an analog signal having the corresponding required delay. By thus providing the appropriate equalization time delay to the signal transmitted by each paging transmitter in a simulcast paging system 20, differences in the time required for the analog signal to propagate from a paging terminal to each paging transmitter are compensated, thereby substantially eliminating phase interference in overlap zones of the paging transmitters.

Abstract: The invention relates to a marine seismic prospecting method intended to allow at least two ships (A, B) simultaneously to prospect on one and the same site, in which the ships each cause shocks in the marine environment and record seismic traces containing useful information on the geology of the substratum using sensors (Cr). One of the ships (B) constitutes a point source of noise for the other ship (A) and generates an undesirable signal which masks the said useful information. According to the invention, this point source (B) of noise is localised in space and its spatiotemporal coordinates (X'(t), Y'(t), Z'(t)) are stored during the recording, relative to a reference frame in which the spatiotemporal coordinates (Xr(t), Yr(t), Zr(t)) of the sensors (Cr) are also recorded, then the recorded seismic traces are processed as a function of the spatiotemporal coordinates of the point source (B) of noise with a view to eliminating the said undesirable signal. <IMAGE>

Abstract: An ultrasonic oscillator drives a tool at a set frequency. An amplitude control runs the oscillator to set the vibration level. A frequency regulator joins the amplitude and the oscillator. A control feedback loop, in the frequency regulator, keeps handpiece linear dynamics. An operational transconductance amplifier, in the oscillator, governs gain of the loop. A circuit connects to the control to retard the rate of current application over time to the amplifier. The circuit has switching to either retard the rate or reset for start up. The amplifier is a current output device with current directly proportional to the bias current and input voltage with bias as gain change for the loop. The circuit limits the bias to the amplifier to modify frequency response and output current. A capacitor delays application of the bias to the amplifier. Replaceable tools of various lengths or shapes positioned along an axis vibrate for surgery at the frequency and a wave length. Tools longer than one wavelength and of configurations tuned to oscillate around the frequency resonate as a function of their material, length and configuration. A flue surrounds the tool and has a hollow elongate semi rigid central body about an axis with a funnel, at one end thereof and a nozzle, at the other to direct annular irrigant/coolant flow therethrough. The funnel and nozzle are resilient. Reinforcing ridges, inside the nozzle, act to maintain concentricity between the flue and nozzle tip and channel irrigant thereabout.
