1. A method of warning a bicycle rider of an object approaching from behind a bicycle, the method comprising the steps of:
- transmitting at least one ultrasonic wave;
receiving at least one first ultrasonic echo from at least one object behind the bicycle;
determining a first time value for the first ultrasonic echo;
storing the first time value in a memory;
transmitting at least one second ultrasonic wave;
receiving at least one second ultrasonic echo from the at least one object behind the bicycle;
determining a second time value for the second ultrasonic echo;
comparing the second time value with the first time value; and
,warning the bicycle rider if the second time value is less than the first time value.

15. A method of warning a bicycle rider of an object approaching the bicycle rider from behind a bicycle, the method comprising the steps of:
-
transmitting an ultrasonic wave; receiving a plurality of ultrasonic echoes from a plurality of objects behind the bicycle; determining a time value for each of the ultrasonic echoes; comparing the time values with stored time values for echoes relative to the objects causing the echoes; and
,warning the bicycle rider if the step of comparing each ultrasonic echo determines that any object from the plurality of objects is approaching the bicycle rider. - View Dependent Claims (16, 17, 18, 19, 20)
