Patent EP-0018716-A3 (EP)
IPC: H04B1/10
Filed: 1980-03-26
Abstract: A noise blanker which has circuitry that enables the 
threshold level of noise blanking to track the average background 
noise level is disclosed. In general, a controllable gate 
(20) receives an input signal and selectively passes and blocks 
the input signal in response to received noise blanking pulses 
which are generated in response to high peak magnitude 
noise impulses. A signal (27, Fig. 4A) related to background 
and impulse noise is extracted from an input signal. A controllable 
gain noise amplifier (31) is utilized to amplify the 
separated background and impulse noise and negative feedback 
circuitry (35, 37, 39; 50, 52, 39) is utilized to maintain the 
average peak output (33, 54) of the noise amplifier substantially 
constant except for occasional large magnitude noise 
impulses which do not substantially change the average peak 
magnitude of the background and impulse noise. The output 
(32, 36, 51) of the controllable noise amplifier (31) is applied to 
a threshold switch means (35, 40, 41, 50, 53, 41) which produces 
blanking pulses (47) in response to the amplified noise 
signal having a peak exceeding a magnitude (43; 56) which is 
greater than the substantially constant peak output level of 
the noise amplifier. This results in a blanker circuit in which 
the threshold level of the blanking pulses closely tracks the 
average peak value (33; 54) of the background and impulse 
noise.

Title: Improvements to apparatus for decoding error-correcting codes
IPC: H03M13/23
Filed: 1984-05-23
Abstract: An improvement to a Viterbi-type decoder for decoding convolutional error-correcting codes whereby decisions regarding which predecessor state to a given state most probably corresponds to the best path terminating in that given state are stored in association with that given state and not in association with the best path. Paths are reconstructed by searching through such stored decisions. Such searches are used to recover a number, possibly greater than one of data symbols for later output from the decoder. The larger this number, the less frequently a search need be carried out.

Abstract: A waste transfer packer having a horizontally reciprocable 
ram operating in a hollow spigot to deliver and compress waste 
material from a chute or hopper, has a spigot adapted to extend

Abstract: A method of treating animal tissue with a time-varying, 
magnetic field and a device for producing such a field 
wherein a substantially unipolar, rectangular electro-­
magnetic treatment signal having pulses of a predetermined

device to prevent the occurrence of a reverse polarity pulse 
upon the fall of the magnetic flux induced by the fall of the 
generated pulse and to diminish high frequency ringing at
