Patent ID: 8552878

Claim:
An apparatus to bypass a voltage drop, the apparatus comprising: a protection module configured to allow electric current to flow from a battery to a load and prevent electric current from flowing to the battery, the battery comprising a non-rechargeable battery, the protection module comprising a voltage drop between the battery and the load; a power source detection module configured to detect an absence of electric power from an electric power source, the electric power source providing electric current to the load when electric power from the electric power source is present; an output voltage detection module configured to detect that a voltage of the battery has fallen below a predefined level; a bypass module configured to, in response to the power source detection module detecting the absence of electric power from the electric power source and the output voltage detection module detecting that the voltage of the battery has fallen below the predefined level, bypass the protection module such that the electric current from the battery reaches the load without the voltage drop of the protection module; and a conservation module configured to deliver, to the load, electric current flowing through the power source detection module.
