Valuing the African Genius

Colbert Tchakounte

Colbert Tchakounte, from Cameroon, has designed and developed the Tchak’s TV Guard which is an automatic plug/unplug device of the coaxial cable (TV antenna) that was patented with the OAPI (African Intellectual Property Organization). The patent was filed under Number 1200900409 on December 08, 2009 and granted under Number 14916 on December 30, 2010.

The Tchak’s TV Guard can automatically separate the coaxial cable (TV antenna) from the TV tuner whenever there is a blackout, a voltage drop, a power surge (due to lightening) or an unstable power supply (below 110 V or above 250 V).

This device is, therefore, connected to the coaxial cable or TV antenna plug, as well as to the TV set power source. It monitors the voltage level of the power source and delays power supply by 15 seconds before transferring it to different types of appliances: TVs, DVD players, amplifiers, decoders, etc. During blackouts, the device will light up and illuminate for about 6 hours the room where it is located.
