Apparatus and method for classifying orientation of a body of a mammal
First Claim
1. An apparatus for providing a classification of body orientation of a mammal in static and/or dynamic states, said apparatus including:
- two position sensors located on an upper body of the mammal to measure body position relative to a frame of reference and to provide first data indicative of said body position;
a memory device coupled to the two position sensors and arranged for storing said first data at least temporarily;
a processor to receive said first data and to process said first data to provide said classification of body orientation in said static and/or dynamic states, wherein said processor implements a Body Orientation Classification (BOC) algorithm for evaluating said body orientation, said BOC algorithm including;
a dynamic classifier configured to identify dynamic movement based on identification of a cyclic pattern in the first data received from the two position sensors;
a static classifier configured to identify posture based on the first data received from the two position sensors mapping to predetermined values; and
a transition classifier configured to identify a pattern of transition in response to a changing state as identified by the static classifier and based on the first data received from the two position sensors comprising a moving window of position values in real time correlating to predefined statistics from observed data, wherein the correlation serves as a confirmation or refutation of the changing state; and
wherein said BOC algorithm updates the predefined statistics based on said first data for subsequent classification of subsequent body position data in a feedback loop, and further outputs a status of the changing state.

Abstract
Apparatus is disclosed for providing classification of body orientation of a mammal. The apparatus includes means (10, 11) for measuring position of said body relative to a frame of reference at one or more points on the body, wherein said means for measuring includes at least one position sensor. The apparatus includes means (12) for providing first data indicative of said position; means (15) for storing said data at least temporarily; and means (13, 14) for processing said data to provide said classification of body orientation. A method for providing classification of body orientation of a mammal is also disclosed.

10. A method for providing a classification of body orientation of a mammal in static and/or dynamic states, said method including:
-
measuring body position of the mammal relative to a frame of reference, said measuring being performed by two position sensors located on an upper body of the mammal to provide said classification of body orientation in said static and/or dynamic states; providing first data indicative of said body position from said two position sensors; storing said first data at least temporarily in a memory device; processing said first data by a processor to provide said classification of body orientation in said static and/or dynamic states by executing a Body Orientation Classification (BOC) algorithm for evaluating said body orientation, said BOC algorithm including; a dynamic classifier configured to identify dynamic movement based on identification of a cyclic pattern in the first data received from the two position sensors; a static classifier configured to identify posture based on the first data received from the two position sensors mapping to predetermined values; and a transition classifier configured to identify a pattern of transition in response to a changing state as identified by the static classifier and based on the first data received from the two position sensors comprising a moving window of position values in real time correlating to predefined statistics from observed data, wherein the correlation serves as a confirmation or refutation of the changing state; updating, by the processor, the predefined statistics based on said first data for subsequent classification of subsequent body position data in a feedback loop; and outputting, by the processor, a status of the changing state. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
