摘要

#CMT# #/CMT# The device (2) has a memory unit (12) receiving data relative to a mobile object through control units (8-10). A measuring unit (14) measures time interval using an internal time base of the control units, where the electronic device is formed with a wrist watch having a function of electronic stopwatch. A calculation unit (13) is arranged for dividing reference length by the time interval, where the electronic device is arranged for indicating a division result on a display unit (4). #CMT# : #/CMT# An independent claim is also included for a moving object speed measuring method. #CMT#USE : #/CMT# Electronic device for measuring speed of a moving object i.e. sail boat. #CMT#ADVANTAGE : #/CMT# The device is simple and easy to carry. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of an electronic device. 2 : Electronic device 4 : Display unit 8-10 : Control units 12 : Memory unit 13 : Calculation unit 14 : Measuring unit.
