for certain times, turning itself on at predetermined
intervals to
check whether it is being addressed by a transmitter. A time-
division multiplexed form of such addressing is specified by
the “POCSAG” paging format. With this form of addressing,
however, power consumption is constant regardless of channel
traffic. Another disadvantage is that, if a receiver is
required to receive large amounts of data during off peak
hours, it must operate continuously.
The inventive paging receiver transitions to a low power
mode on command for a dynamically controlled time. Such a
sleep command takes the form of a special address that affects
all pagers preprogrammed to respond so; it determines the
sleep period. Absent the sleep command, the paging receiver
operates in the standard POCSAG format.
Claim 25, which is representative for our purposes,
follows: 25. A radio pager receiver comprising
means for manually shutting the receiver
off, means for automatically turning on the
manually shut off receiver for receipt and
storage of cyclically transmitted wireless
