A device for use with an infant that provides audible or visual signals
based on a sensed lack of motion from an infant to stimulate motion by the
infant. The sounds or light generated by the device are designed to
encourage movement in an infant that is not moving, in order to reinitiate
spontaneous movement by the infant and to alert a caregiver as to lack of
movement by the infant. The device can also be configured to provide
different audible sounds for different movements that are sensed by the
device. The motion is sensed by an accelerometer disposed within the
device that is formed of a monolithic integrated circuit chip. The
accelerometer is connected to a controller that analyzes the accelerometer
output signals and controls the sound or lights of the device in response
to the accelerometer signals.
