Abstract: A method for detecting a delimiter pattern (SOF) in a signal stream containing a carrier or subcarrier modulated by the delimiter pattern comprises: specifying an expected delimiter occurrence time (t1) of an occurrence of the delimiter pattern and a tolerance zone (tz) within which the expected delimiter occurrence time (t1) may jitter; approximating, within the tolerance zone (tz), a zero of a cross correlation function (CCF) of the data stream with the delimiter pattern, or detecting the phase (f) of the carrier or subcarrier in respect to an arbitrarily defined reference position within the tolerance zone (tz), e.g. in respect to the expected delimiter occurrence time (t1); calculating a first maximum of the cross correlation function (CCF) within the tolerance zone (tz) by use of the approximated zero or phase (f); calculating all other maxima of the cross correlation function (CCF) within the tolerance zone (tz); detecting the highest maximum among the calculated maxima, which highest maximum is representative for the moment in time of occurrence of the delimiter pattern.

Abstract: An apparatus includes a base having a first surface and an array of pillars. Each pillar of the array of pillars includes (i) a first end attached to the first surface of the base; (ii) a second end having an electric charge retention portion; (iii) a physical separation from adjacent pillars of the array of pillars; and (iv) an electrical conductor configured to electrically connect the electric charge retention portion with a bus structure. The bus structure is configured to addressably connect with the electrical conductor of each respective pillar of the array of pillars.
