Appeal No. 2004-1168
Application 09/884,518
INVENTION
Appellant’s invention relates to a subsurface object locator accessory device 12
for a hand drill 10 having a drill housing 14. See Appellant’s specification, page 2,
lines 22-24. The locator 12 includes an accessory housing 16 having a substantially flat
surface and an attachment member 46 for detachably mounting the accessory housing
16 to the drill housing 14. The locator 12 has sensing circuitry contained within the
accessory housing 16 for detecting a subsurface object 61, 62 and an object indicator
24 connected to the sensing circuitry for indicating the presence of the subsurface
object 61, 62. See Appellant’s specification, page 2, lines 24-31.
Claim 1 is representative of the claimed invention and is reproduced as follows:
A subsurface object locating accessory for use with
a hand drill having a drill housing, the accessory
comprising:
an accessory housing having a substantially flat
surface for sliding across a wall surface and an attachment
member for detachably mounting the accessory housing
to the drill housing;
sensing circuitry contained within the accessory
housing for detecting subsurface objects probed by said
accessory; and
an object indicator connected to the sensing
circuitry for indicating the presence of a subsurface object.
