Abstract
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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
171 words
An apparatus for detecting a rotational movement of a body of a child to which said apparatus is attached comprising: at least two tilt switches capable of determining when said apparatus has been rotated by a preselected inclination angle measured with respect to a vertical reference axis of rotation through the body of said child, and in response to said determination, generating an inclination signal; and a controller coupled to said at least two tilt switches capable of detecting said inclination signal from said at least two tilt switches, and in response to said detection, generating an alarm signal; and at least one physiological condition monitor capable of being coupled to said child for detecting signals that represent at least one physiological condition of said child, wherein said controller is coupled to said at least one physiological condition monitor, and wherein said controller, in response to detecting said inclination signal from said at least two tilt switches, is capable of initiating the operation of said at least one physiological condition monitor.
Claim 2
Independent Claim
171 words
An apparatus for detecting a rotational movement of a body of a child to which said apparatus is attached comprising: at least two tilt switches capable of determining when said apparatus has been rotated by a preselected inclination angle measured with respect to a vertical reference axis of rotation through the body of said child, and in response to said determination, generating an inclination signal; and a controller coupled to said at least two tilt switches capable of detecting said inclination signal from said at least two tilt switches, and in response to said detection, generating an alarm signal; and at least one physiological condition monitor capable of being coupled to said child for detecting signals that represent at least one physiological condition of said child, wherein said controller is coupled to said at least one physiological condition monitor, and wherein said controller, in response to detecting said inclination signal from said at least two tilt switches, is capable of initiating the operation of said at least one physiological condition monitor.
Claim 3
Dependent Claim
57 words
An apparatus as claimed in claim 1 wherein said preselected inclination angle is a clockwise rotation of approximately one hundred eighty degrees around said vertical reference axis of rotation, where said clockwise rotation indicates that the child has moved from a position of lying on the child's back to a position of lying on the child's stomach.
Claim 4
Dependent Claim
57 words
An apparatus as claimed in claim 1 wherein said preselected inclination angle is a counterclockwise rotation of approximately one hundred eighty degrees around said vertical reference axis of rotation, where said counterclockwise rotation indicates that the child has moved from a position of lying on the child's back to a position of lying on the child's stomach.
Claim 5
Dependent Claim
32 words
An apparatus as claimed in claim 1 wherein said controller receives said inclination signal for length of time that exceeds a preselected length of time before said controller generates said alarm signal.
Claim 6
Dependent Claim
65 words
An apparatus as claimed in claim 1 further comprising a signaling device coupled to said controller capable of receiving said alarm signal, and in response to receipt of said alarm signal, one of: (a) generating an audible alert and (b) wirelessly transmitting an alert message to a remote monitoring device and (c) transmitting an alert message to a remote monitoring device via a computer network.
Claim 7
