Title: Voice paging system providing deferred paging capability
IPC: H04W84/02
Filed: 1989-05-05
Abstract: A paging system is provided for transferring 
information to a paging receiver (12), including a central 
controller (20) having a paging controller (22) for 
receiving the information, an encoder (24) coupled to the 
paging controller for generating a selective call paging 
signal designating the paging receiver. The paging 
receiver receives and decodes the selective call paging 
signal generating a coded acknowledgment signal indicating 
whether the selected paging receiver is in a normal or a 
deferred operating mode, and transmits this signal back to 
the paging controller. When the coded acknowledgment 
signal indicates the paging receiver is in the normal 
operating mode or memory is available, the information is 
transmitted to the paging receiver. When the coded 
acknowledgment signal indicates the paging receiver is in 
the deferred paging operating mode, and the paging receiver 
memory is full, the information is stored in the central 
controller for transmission at a later time.

preparation of the novel compositions may be 
carried out in inert solvents or in inert polymeric 
compositions in a melt blending step.

Patent EP-0338737-A3 (EP)
Title: Circuit arrangements
IPC: H03K3/55
Filed: 1989-04-14
Abstract: A circuit arrangement for applying a current pulse to 
a load 9, such as a magnetron or klystron, includes a main 
switch 14 and an auxiliary switch 15. Prior to 
transmission of the pulse, charging current is applied 
via an inductor 10 to a pulse forming network 12. Once 
charging is complete, the main switch 14 is triggered and 
the pulse is applied to the load 9 via a pulse 
transformer 13. After transmission of the pulse, 
energy is transferred from the core of the transformer 13 
to the pulse forming network 12. When maximum energy 
transfer has almost occurred, the auxiliary switch 15 is 
triggered, causing an inverse voltage to be applied across 
the main switch 14. This ensures that the main switch 14 
can undergo recovery, even under adverse operating 
conditions.

Patent EP-0375364-A3 (EP)
Title: Data processor with zero execution clock count for one or both of branch and compare instructions
IPC: G06F9/30
Filed: 1989-12-19
Abstract: The data processor of this invention makes zero 
the execution clock count of a branch instruction, a 
compare instruction, or a compare instruction and follow­
ing branch instruction when a series of instructions 
executed in the past is again executed. The data 
processor of this invention is provided with a history 
storage unit (4a; 4b; 4c; 4d) which stores as its address 
tag the address of an instruction executed before the 
branch instruction or compare instruction, and stores the 
address of an instruction to be executed next the branch 
or compare instruction or both instruction code of an 
instruction to be executed next the branch or compare 
instruction and an address used for pre-fetching an 
instruction following the instruction code. While the 
instruction before the branch or compare instruction is 
decoded, the history storage unit is searched to obtain an 
instruction to be next executed. The obtained instruction 
is executed immediately after the execution of the 
instruction immediately before the branch or compare 
instruction. If the instruction for which execution clock 
count is to be made zero, includes a compare instruction, 
in parallel with the execution of the obtained instruc­
tion, a comparison is carried out by using the operand 
 
 
information of the compare instruction stored in the 
history storage unit. If the instruction for which 
execution clock count is to be made zero, includes a 
conditional branch instruction, in parallel with the 
execution of the obtained instruction, a verification of a 
branch prediction is carried out by using the condition 
code of the branch instruction stored in the history 
storage unit.

Title: Method of derermining an optimal end node to end node route through a data communications network
IPC: H04Q3/66
Filed: 1989-05-23
Abstract: When computing a least weight path from an origin node to 
a destination node in a data communication network, a 
route-computing network node uses information provided by 
the origin and destination nodes to compute least weight 
routes from those nodes to adjacent network nodes. The 
route-computing network node uses information in the 
topology database to compute least weight routes from 
network nodes adjacent the origin node to network nodes 
adjacent the destination node. The results of the compu­
tations are combinated to determine an optimum route from 
the origin node to the destination node. The topology 
database need not include information about the transmis­
sion groups connecting the origin/destination nodes to 
network nodes.

Patent EP-0391539-A3 (EP)
Title: Laser engraver with x-y assembly and cut control
IPC: B23K26/08
Filed: 1990-03-08
Abstract: The present invention provides a laser engraver for 
engraving a pattern on a workpiece. The pattern is 
established on the workpiece by using a X-Y assembly(32a,32b) to 
move a laser beam in two dimensions relative to the 
workpiece. The X-Y assembly employs a X proportional-­
integral-differential (PID) controller (34a) and a PID (34b) to 
generate control signals for moving the X-Y assembly. 
The PIDs generate the control signal based upon the 
current position of the laser beam and a target position 
for the laser beam. The current position is provided by 
encoders (36a,36b) operatively attached to motors (38a,38b) that, in turn, 
move mirrors (44a,44b) that direct the laser beam to the 
workpiece. The depth of cut is, preferably, controlled 
by using the integral of the difference between the 
position of the laser beam as it is moved by the X-Y 
assembly and a reference position. Alternatively, 
proportional control based upon the absolute difference 
between the position of the laser as it is moved by the 
X-Y assembly and the reference position can be utilized.
