摘要:
Printed products, such as newspapers are fed past a counting station arranged in imbricated fashion, preferably folded edges passing downstream first. A high intensity light source is arranged so that its light beams are oriented at an angle which, while illuminating upper surfaces of the newspapers, causes the forward folded edges to cast a shadow upon the upper surface of a downstream newspaper that the forward edge of the newspaper creating the shadow rests upon. An image sensing device creates an image of a given region which includes the leading edge of the newspaper creating the shadow. This image is compared with stored criteria to determine if the nullshadownull is due to a leading edge of a newspaper and to thereby discriminate a newspaper leading edge from other spurious conditions which, although they may create a nullshadownull, fail to meet the criteria of a leading edge of a newspaper.
摘要:
A method of calculating the carry out word from a shift register such as a CRC encoder, decoder or error trapping circuit having feedback taps at positions determined by a generator polynomial, in which the carryout word of length K is calculated from the formula: carryout_wordnullselect_word.top_word_matrix carryout_word being a 1nullK row vector, top_word_matrix being calculated from the top K bits of the shift register, and select word being a 1nullK row vector determined from the generator polynomial.
摘要:
A counting device with control system includes a housing with a rotating wheel therein. The wheel includes a plurality of seats for each item to be counted. Upon deposit of the items into the housing, each item is seated for discharge through a housing aperture, past a sensor operating a counter and onto a conveyor line. A baffle adjacent the housing aperture directs the counted items to one or the other longitudinal side of the conveyor line. A control system controls the baffle position according to a preselected item count. An air pressure system assures a proper seating of each items and discharge through the housing aperture.
