There was an article in Scientific American many years ago. They used a
magnet mounted on the end of a stick attached to the pendulum arm. The arc
of the magnet swung through a hole in the middle of a solenoid coil. A pulse
on the coil at the right time provided the nudge with no physical contact.
These are my opinions. I hate spam.
