6. Stengel discloses that “ [o]ne available method by which the
decoder 206 decodes the detected CSS is by comparing it to a bank of
available CSSs stored at a memory block 210 to determine which one has
been received.” (Col. 3, ll. 28-32).
7. Stengel further discloses that “[t]he output of the comparator 212
which is a signal corresponding to the result of this comparison is connected
to a battery saver switch 216.” (Col. 3, ll. 49-52).
Lemelson
8. Lemelson describes “an automatic means for reading the codes of
the rings to cause or enable a switch, … ,or a door lock to open…” (col. 1,
ll. 19-23).
9. In Lemelson, the “invention is directed to a simple electronic
means for generating an electrical code in response to reading a recording of
such code provided in the crown or alongside the crown of a finger ring to
enable a switch to close or a doorlock to open…” (col. 1, ll. 43-51).
10. In Lemelson, “[t]he comparator 15 compares the parallel code
with one or more authorized codes presented to it from a memory 16.” (Col.
3, ll. 66-68).
11. In Lemelson, “[i]f the code so presented matches the code or
codes in the comparator memory 16, a signal is generated on an output 15A
of comparator 15 which is either applied directly or indirectly to a motor or
solenoid 21 operating the lock 21L to open.” (Col. 4, ll. 3-7).
