Patent EP-0107122-A1 (EP)
Inventor: CROUSE WILLIAM GEORGE
IPC: H04B3/20
Filed: 1983-10-05
Abstract: An adaptive echo suppressor for a sub-band speech coder communications system analyzes and uses the N contiguous sub-bands of the speech coder. An estimate of the echo return loss R for each sub-band is calculated in an R-Estimate circuit (5) as the ratio of the modulator energy M to the demodulator energy D. Expected echo level estimates E are calculated in an echo level estimate circuit (6) as the product RxD. A switching decision logic (7) compares the modulator energy M against the expected echo level estimate E and controls the interruption switch (9) and the path attenuator (8), based upon whether the individual sub-band energy at the modulator (3) exceeds or not the expected echo level estimate E for that sub-band.

Abstract: An electrode having a lead base and a catalyst is manufactured by (a) compressing titanium sponge particles so as to consolidate them to a coherent porous layer, (b) applying the catalyst to the titanium sponge particles, and (c) fixing the layer of consolidated sponge particles to the lead base. The catalyst is formed on the titanium sponge particles before or after their consolidation to a coherent layer. This layer may be produced and fixed to the base in a single compressing and fixing step combining (a) and (c). Oxygen is anodically evolved at a reduced, stable potential by means of this electrode, so that it can be usefully applied as an anode in processes for electrowinning metals from acid electrolytes.

Abstract: Water-soluble biologically active conjugates are made by coupling a protein, e.g. an enzyme, with an alkylene glycol ester of a polyuronic acid under alkaline conditions. The polyuronic acid is thus coupled to the protein by amide linkages and to the alkylene glycol residues via ester linkages. As compared with the unconjugated protein, the conjugates have better activity at higher pH values and higher temperatures.

Abstract: A phase locked loop (PLL) arrangement comprising a local crystal oscillator (23) and a tapped delay chain (15) of analog delay elements (17). Connected to the delay chain taps are a flash register (25) consisting of latches which store the tap signal values at each data signal transition, and an output multiplexer (37) for selecting one of the tap signals as phase shifted output clock. Contents of the flash register are encoded by an encoder (33) which furnishes a value representing the phase offset between data signal and local clock signal. By a look-up table (41), the phase offset is converted to a phase selection value controlling the output multiplexer. The delay chain serves two purposes: Phase offset detection and clock signal phase shifting. No sampling or control signals are used which have a higher frequency than that of the system clock.

Abstract: A digital acquisition system includes a highspeed sampling gate with analog memory for sampling input signals. The samples are converted to digital representations and stored in a digital memory. The digital representations are selectively recalled from the digital memory and fed back as estimators to the sampling gate's analog memory. Since the estimators are essentially the previous samples for each point of a given waveform, the stored waveform converges to the input waveform very quickly, facilitating accurate waveform replication. Embodiments for both sequential sampling and pseudo-random sampling are provided. Operational techniques of the digital acquisition system include noise reduction, loop gain determination, adaptive filtering and signal averaging.
