Patent ID: 8651748

Claim:
A connecting bridge ( 10 ) to connect two optical units ( 110 ), each comprising a battery, comprising: at least one coupling ( 20 ) for coupling each optical unit ( 110 ) to the connecting bridge ( 10 ), said connecting bridge being fitted with both mechanical coupling elements ( 22 ) and electronic coupling elements ( 24 ) that are configured in a manner that the electronic coupling elements ( 24 ) set up electronic contact between the connecting bridge ( 10 ) and the optical units ( 110 ) coupled thereto when the mechanical coupling elements ( 22 ) set up mechanical contact between the coupled optical units ( 110 ) and the connecting bridge ( 10 ), a connector ( 30 ) extending at least in segments between each of the couplings ( 20 ) and mechanically linking the couplings to each other, and an analyzer ( 40 ) which is part of the connecting bridge ( 10 ) and can be electronically connected to the electronic coupling elements ( 24 ) of the optical units ( 110 ) and can exchange electronic signals with the electronic coupling elements ( 24 ) and/or can set up an electric connection between the electronic coupling elements ( 24 ) of the couplings ( 20 ), the analyzer ( 40 ) analyzes signals received from the electronic coupling elements ( 24 ) regarding a battery status of the optical units ( 110 ) and generates an electric connection to the batteries of both optical units 110 via the electronic coupling elements ( 24 ) to support the battery having a lower charge by the battery having a larger charge.
