A method and apparatus provides for accurately synchronizing a plurality of sensors, as well as for providing accurate timing information (e.g. timing metadata) associated with the synchronized data capture. According to one aspect of the invention, an apparatus includes a synchronization circuit that stores a counter having a value corresponding to the delay characteristics of an associated sensor. The counter is used to provide a synchronization pulse to the associated sensor which is offset from a desired synchronization time by an amount that will compensate for the delay characteristics. In one example, one counter is provided for each associated sensor, allowing a high degree of accuracy in synchronization among a plurality of sensors. According to another aspect of the invention, the synchronization pulses are locked onto and derived from a pulse received from a GPS receiver. The GPS receiver is also used to mark time associated with the generated synchronization pulses, and thus obtain highly accurate time information (e.g. metadata) associated with the synchronization pulses provided to the sensors.

Systems, methods, and computer-readable media are disclosed for error-compensated counting of Hall states for motor position feedback and/or commutation. An indicated Hall state is detected by digital Hall state sensors and a duration of the Hall state is compared to a specified time period.

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 “shadow” 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 “shadow”, fail to meet the criteria of a leading edge of a newspaper.
