Appeal No. 1998-0936
Application 08/369,011 Page 2
BACKGROUND
Appellants' invention relates to a wireless pointing device
for remote cursor control. A circuit is connected to IRLEDs for
sequentially pulsing the IRLEDs to individually and sequentially
emit modulated infrared light signals. An understanding of the
invention can be derived from a reading of exemplary claim 1,
which is reproduced as follows:
1. A hand-held pointing device for remotely controlling a
cursor on a display device comprising:
at least three infrared light emitting diodes (IRLEDs), each
of said IRLEDs aimed off a main or pointing axis of the device in
different directions;
at least one activating device on said hand-held pointing
device; and
a circuit connected to each of said IRLEDs for sequentially
pulsing said IRLEDs with pulse trains so as to cause the IRLEDs
to individually and sequentially emit modulated infrared light
signals to position said cursor.
