Patent ID: 7116008

Claim:
A bicycle signal processing device comprising: a first bicycle signal processing element that generates a first signal at a first impedance, wherein the first bicycle signal processing element is disposed within a housing; a first connector coupled to the housing; an external output terminal formed at the first connector and having an exposed electrically conductive output contact surface for communicating the first signal from the first bicycle signal processing element to a location outside the housing such that the output contact surface is adapted to contact a second contact surface of a second external terminal formed at a separate second connector when the first connector is connected to the second connector, wherein the output contact surface is exposed to an outside environment external to the housing when the first connector is unconnected from the second connector; and an impedance converting circuit coupled between the first bicycle signal processing element and the external output terminal for converting the first signal to a second signal at a second impedance at the external output terminal to reduce voltage variations caused by current leakage in a signal path after the external output terminal.
