Control system for a child swing
First Claim
Patent Images
1. A child swing, comprising:
- a child seat;
at least one swing arm coupled to the child seat;
a drive mechanism that includes a motor configured to impart torque to the at least one swing arm so that the child seat moves in an arcuate path;
a phase control subsystem that generates a motor drive signal configured to maintain a desired lead angle between a phase of the drive mechanism and a phase of the swing arm; and
an amplitude control subsystem configured to steer the phase control subsystem based on a correlation of an actual height of the child seat to a selected height of the child seat.

Abstract
A control system for a child swing that comprises a drive mechanism that includes a motor configured to impart torque to the at least one swing arm so that a child seat moves in an arcuate path. A phase control subsystem generates a motor drive signal configured to maintain a desired lead angle between a phase of the drive mechanism and a phase of the swing arm. An amplitude control subsystem configured to steer the phase control subsystem based on a correlation of an actual height of the child seat to a selected height of the child seat.

12. A control method for a child swing comprising:
-
correlating a phase of a drive mechanism to a phase of at least one swing arm to maintain a selected lead angle of the phase of the drive mechanism relative to the phase of the swing arm; and generating, based on the correlating, a motor drive signal configured to maintain the selected lead angle of the phase of the drive mechanism relative to the phase of the swing arm, wherein the generation of the motor drive signal is influenced by a comparison of an actual amplitude of the child swing to a selected amplitude of the child swing. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)

21. One or more computer readable storage media encoded with software comprising computer executable instructions and when the software is executed operable to:
-
correlate a phase of a drive mechanism to a phase of at least one swing arm to maintain a selected lead angle of the phase of the drive mechanism relative to the phase of the swing arm; and generate, based on the correlating, a motor drive signal configured to maintain the selected lead angle of the phase of the drive mechanism relative to the phase of the swing arm, wherein the generation of the motor drive signal is influenced by a comparison of an actual amplitude of the child swing to a selected amplitude of the child swing. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29)
