ABSTRACT:
A digital wristwatch having a case and strap also serves as a computer to display speed, distance, and pedaling cadence when temporarily attached to a holder on the bicycle handlebar. Wheel and sprocket sensors are connected to electrical terminals in the holder. The wristwatch is provided with external electrical terminals connected to a microcomputer in the watchcase which uses signals from the sensors when the watchcase is temporarily retained in the holder. The microcomputer is preprogrammed to provide an improved dual mode circuit which keeps time in a "watch mode" and which uses the sensor signals to make speed, distance, and cadence computations and display them in a "bike mode." The computations may be altered and new constants entered in a "calibration mode," through manual actuators. Changes of state within a mode are responsive to manually actuated push-buttons, to lapse of predetermined time periods or to condition of an annunciator.
