Polley went on to design the next-generation remote controls with engineer Robert Adler. The "Space Command" system used aluminum rods, similar to tuning forks, which were struck by hammers toggled by the buttons on the device, producing high-frequency tones that would then control functions on the television set.
By the 1960s, Zenith remotes began using ultrasonic signals, a technology which was used for the next 25 years, until being replaced by infrared systems capable of more complex commands.
Polley and Adler shared a Technology & Engineering Emmy Award in 1996 for their "Pioneering Development of Wireless Remote Control for Consumer Television."
In 2009, Polley received the Institute of Electrical and Electronics Engineers Consumer Electronics Award for his contributions to the technology of the wireless remote control for television and other consumer electronic products.
