Appeal No. 2002-1392
Application No. 09/390,996
said support unit comprising a standing part;
said standing part having a support surface for supporting
the body of the user; and
a sensor device for detecting a direction and a magnitude of
a position of a projection of the body's center of gravity into
the support surface relative to a predetermined original position
in the support surface,
wherein the direction and the magnitude of the tilt of the
support surface are detected for generating corresponding sensor
signals,
wherein the support surface is mounted on the base part of
said bearing device such that it can either rotate about an axis
or move in a direction which is parallel to said axis,
said axis being one of:
vertically oriented when the support surface is
oriented horizontally,
perpendicular to at least the support surface,
running through at least the base part and the support
surface when the support surface is not tilted,
running through at least the support surface and a
tiltable mounting, or
running through at least the base part and a tiltable
mounting,
wherein the sensor device detects either the direction and
the magnitude of a rotational movement of the body of the user
about the axis or detects at least the magnitude of a vertical
movement of the body's center of gravity, and generates
corresponding sensor signals.
The prior art references of record relied upon by the
examiner in rejecting the appealed claims are:
