About This Design

Hedy Kiesler Markey G. Antheil US Patent 2292387 Large Clock

Hedy Kiesler Markey G. Antheil US Patent 2292387 Large Clock

Let others know of one particular woman's contributions to our modern wireless world with this "Secret Communication System" clock featuring U.S. Patent 2,292,387 as filed by Hedy Kiesler Markey and composer George Antheil. Markey's and Antheil's frequency-hopping system was designed to jam radio-controlled torpedoes by continually changing the radio signals sent to them. This system, similar to how piano rolls work, shares some concepts with modern spread-spectrum communication technology as used in today's wireless telephones (GPS, Wi-Fi, and Bluetooth). Let your technological pioneering spirit shine with this clock!

Thos is a great clock. Unlike the last Hockey Night in Canada clock, there is no second time that ticks. With this, the hands change automatically, and when I need to adjust the time, I would move the hand. The clock has the famous Hockey Night in Canada logo with a blue background. Similar to the logo that is shown on Hockey Night in Canada!
