title: Device for synchronization of cinematographic and bioelectric data.
abstract: The correlation of mechanical action and bioelectric activity during muscular movement necessitates accurate synchronization of photographic and bioelectric recordings. A device is described which in conjunction with a movie camera provides a pulse as the shutter opens, counts the number of the frame, displays the decimal count in the camera field, and provides a "decimal coded" output pulse for synchronizing other recordings.
