Abstract
A bicycle cycle computer includes a main unit having a primary microprocessor, a display and tlree contacts; a plurality of sensors; and a secondary microprocessor provided on the bicycle and connected between the plurality of sensors and the main unit, for receiving parallel signals outputted from the plurality of sensors, the secondary microprocessor converting the received parallel signals into a serial signal and generating a synchronous clock signal, which are transmitted to the main unit through two of the contacts of the main unit, processed by the primary microprocessor and displayed on the display.
Claims30
A bicycle computer comprising:
- a first processing unit disposed in a mounting bracket for mounting the bicycle computer to the bicycle;
- a plurality of sensors, each sensor providing sensor data in parallel format to the first processing unit;
- wherein the first processing unit receives the sensor data from the plurality of sensors in parallel format and outputs serial format data corresponding to the sensor data;
- a separate main unit housing including a display wherein the main unit housing is detachably mounted to the mounting bracket;
- and
- a second processing unit for receiving the serial format data from the first processing unit and for outputting display data to the display.
A bicycle computer comprising:
- a mounting bracket for mounting the computer to the bicycle, wherein the mounting bracket includes a first processing unit;
- a separate main unit housing including a second processing unit, wherein the main unit housing is detachably mounted to the mounting bracket;
