Appeal No. 1998-0219 Page 9
Application No. 08/265,000
Specifically, the reference includes the following disclosure.
If within a certain amount of time the first
interrogation unit 10 did not receive a response
from
the addressed responder unit, the first
interrogation unit 10 might request that the second
interrogation unit 16 and/or additional
interrogation units 16a send a second or an
additional RF interrogation signal addressed towards
this specific responder unit. Should one or
additional of these other interrogation units 16,
16a receive a response from the addressed responder
unit, they might then relay this information back to
first interrogation unit 10. In this manner, a
network of interrogation units might be used to
detect as regards to the presence or to locate a set
of objects containing responder units having known
addresses.
Col. 9, ll. 17-26. Schuermann lacks a suggestion, however,
that the second interrogation unit 16 and additional
interrogation units 16a cannot send their second or additional
RF interrogation signals, respectively, at the same time. In
other words, there is no suggestion that each of the
interrogation units be allowed to start and complete its
transmission of an RF interrogation signal without any of the
other units beginning to transmit.
