Swinging magnet toy schematic

This embodiment of swing motion sensor is advantageous in that it is capable of providing the absolute position and velocity of the seat at any point along the seat's swing path. The support for a Foucault pendulum is a bearing that rotates in the horizontal plane. Various embodiments of these drive systems and their respective control circuits are described herein. The schematic would simply be that the reed switch is in series with the coil, after the battery. Similarly to the swingthe user first moves the seat away from its resting point and release the seat such that the electromagnetic coil swings past the sensing point of the swing motion sensor We first notice that the frequency now in more like 2. The circuit pulses the 18 mH coil causing the small magnet to swing.

The voltage inverts, driving the drain more positive so that reverse biased integral diode will never be forward biased.

Electromagnet-Powered Pendulum

The arcuate shape of the support member is substantially parallel to the swing path of the seat This allows the electromagnetic drive system to generate the torque necessary to drive the seat with less power than a drive system having less mechanical leverage. However, when the velocity sensing point is in the same position as the target sensing point, the percentage of time the seat is on either side of the velocity sensing point i. For example, in one embodiment, the swing control circuit decreases the current pulse width by 8 milliseconds anytime the current velocity is greater than the target velocity, with the pulse width being zero anytime the current pulse width is calculated to be less than 16 milliseconds. The housing is connected to the swing arm such that its upper end is positioned beneath and adjacent the support member
