Hinged Device With Multiple Accelerometers
First Claim
1. An apparatus for determining relative spatial orientation of a two-piece hinged body, comprising:
- a first member having one or more first accelerometers disposed therein to provide a first signal proportionate to the acceleration of the first member along one or more axes;
a second member having one or more second accelerometers disposed therein to provide a second signal proportionate to the acceleration of the second member along the one or more axes;
one or more hinges pivotably connecting the first and the second members; and
a controller to receive the first signal and the second signal and to calculate the spatial orientation of the first member with respect to the second member.

Abstract
Apparatus, systems and methods for determining relative spatial orientation of a first member and a second member connected by one or more hinges are provided. A first member having one or more first accelerometers disposed therein can provide a first signal proportionate to the acceleration of the first member along one or more axes. A second member having one or more second accelerometers disposed therein can provide a second signal proportionate to the acceleration of the second member along one or more axes. One or more hinges can pivotably connect the first and second members. A controller can receive the first signal provided by the one or more first accelerometers and the second signal provided by the one or more second accelerometers to calculate the spatial orientation of the first member with respect to the second member.

8. A method for determining relative spatial orientation of a two-piece hinged body, comprising:
-
disposing one or more first accelerometers within a first member; disposing one or more second accelerometers within a second member; generating one or more first signals from one or more first accelerometers, wherein the one or more first signals are proportional to acceleration along one or more axes in a set of orthogonal axes; generating one or more second signals from one or more second accelerometers, wherein the one or more second signals are proportional to acceleration along one or more axes in the set of orthogonal axes; transmitting the one or more first signals and the one or more second signals to one or more controllers; calculating the difference along corresponding axes between the one or more first signals and the one or more second signals to provide a differential acceleration value along each axis which can provide an indication of relative spatial orientation between the first and second members; and generating an output signal from the one or more controllers based upon the relative spatial orientation between the first and second members. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A system for determining relative spatial orientation of a two-piece hinged body, comprising:
-
means for generating one or more first signals, wherein the one or more first signals are proportional to the acceleration of a first member along one or more axes in a set of orthogonal axes; means for generating one or more second signals, wherein the one or more second signals are proportional to the acceleration of a second member along one or more axes in a set of orthogonal axes, and wherein the first member and the second member are pivotably connected using one or more hinges; means for transmitting the one or more first signals and the one or more second signals to one or more controllers; means for calculating a differential acceleration value along each axis; and means for generating an output from the one or more controllers to interface with one or more devices based upon the calculated differential acceleration along one or more axes.
