Pedometer devices

摘要

The invention provides a pedometer device of electronic form which may be accommodated in a wrist watch housing, if desired within an electronic wrist watch together with the watch parts. A visual display is produced by an electronic processor responsive to a read only memory, settable to provide a unit distance reference, and counter fed from a motion sensitive modulator. The ROM and counter can be arranged such that no multiplier device is required. The modulator may be in the form of a mass-loaded wire of spring-quality metal projecting into a surrounding contact cylinder. This arrangement gives a construction compact enough for housing within the watch case.
