Abstract
The present invention comprises an apparatus and method for detecting a rotational movement of a body. An advantageous embodiment of the invention is capable of detecting a rotational movement of the body of a child. The invention can provide a care giver information concerning the position of the body of a child in the care giver's care. The invention is especially useful in warning when a child moves from a position of lying on its back to a position of lying on its stomach. The invention comprises at least two tilt switches capable of detecting when the apparatus of the invention has been rotated by a preselected inclination angle of approximately one hundred eighty degrees. The invention also comprises a controller that is capable of receiving a signal from the tilt switches and generating an alarm signal. The apparatus also comprises an alarm signaling device that is capable of sending the alarm signal to alert a care giver that a child has rolled over onto his or her stomach. The alarm signaling device may be an audio speaker or may be a radio frequency transmitter capable of sending a radio signal to a base station radio receiver. The apparatus is also capable of initiating the operation of physiological condition monitors in response to an alarm signal. The apparatus is also capable of detecting a rotational movement of an inorganic body such as a shipping crate that contains a product that must be stored and shipped in an upright position.
