Appeal 2007-0481
Application 10/654,049
processor 114. Moisture and salt on a user’s hand, when applied across the
strips 122 and 124, will short circuit the strips allowing a small amount of
current to flow from a source through the strips via the user’s hand.
Resistance between the user’s hand and the strips drops sharply permitting
an increase[d] amount of current to flow and producing a current pulse in the
detection circuit. The detection circuit then provides the sensor output
signal to the processor 114 (Specification, para. [0014]).
4. Appellant’s Specification gives no specific definition of, and cites
no particular material properties for the term “carbon fiber” (Id.).
5. Davis teaches a wireless telephone including a housing, and a
sensor on the surface of the housing, responsive to user macro-manipulation
(squeezing), to provide a sensor output (Col. 1, ll. 49-51; col. 5, ll. 52-63).
6. In Davis, when the user grasps the housing 302, the conductive
nature of the human hand causes a current to flow between first plate 306
and second plate 308 (of a capacitance switch 304). This completes a
circuit, which is detected by the switch detector 346. In response, the switch
detector sends a signal to the controller 22 (Col. 5, ll. 57-62).
7. Davis teaches that the wireless phone may be controlled to initiate
a communication (“send”), end a communication (“standby” or “on hook”),
or redial a call responsive to receipt of the signal from the switch detector
(Col. 2, ll. 45-56).
8. Naboulsi teaches a vehicle safety system including a pair of
sensors S1, S2 mounted on a steering wheel, which sensors are capable of
sensing a physiological condition of the driver, including electrical skin
conductivity of the driver’s hand while gripping the steering wheel.
