Concept Search - What can I type?
For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.
Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.
Some serial storage memories, such as those implemented with CCD (charge) coupled device) technology, require the generation of staggered timing pulses, as shown in Fig. 1.

Staggered Control Pulse Generator
Some serial storage memories, such as those implemented with CCD
(charge) coupled device) technology, require the generation of staggered timing
pulses, as shown in Fig. 1.
The pulses of Fig. 1 can be produced without segmented delay lines and
with less cost and improved accuracy by the combination of a counter and a
decoder, as shown in Fig. 2. Four-bit binary counter 1 receives clock pulses on
line 2 and provides the sequence of output pulses A, B, C, D of Fig. 3 on the
designated lines of Fig. 2 in a conventional manner.
Outputs A and B are not used. Outputs C and D are applied to a two input-
four output decoder 3 which generates the desired staggered pulse sequence
P1, P2, P3 and p4 of Fig. 1 on the designated lines. The ""down'' portions of
output Pl are generated while inputs C and D are both ""down'', output P2 is
generated while C is ""up'' and D is ""down'', and so on, as can be seen by
inspection of the waveforms.
