Patent EP-0376517-A3 (EP)
IPC: H04M3/42
Filed: 1989-12-08
Abstract: A computer connected to an ISDN central office switch via an ISDN 
digital subscriber line, provides management information regarding activities of a 
plurality of telephone agents. The computer has shared call appearances with a 
number of telephone agent stations and receives shared call appearance associated 
messages from the switch reflecting call handling messages exchanged between the 
ISDN switch and each of the agent stations. The messages are interpreted by the 
computer, which generates station status information and management information 
such as the number of calls handled, average holding time per call, etc. The 
computer may be connected simultaneously to several central offices via ISDN 
subscriber lines and generate management information for a group of geographically 
separated agents, such as home telemarketing agents operating out of their individual 
homes and connected to different central offices. Based on the generated status and 
management information, the computer performs an incoming call management 
function by selecting agents connected to different switches for handling incoming 
calls and transmitting to the ISDN switch appropriate messages for causing the 
switch to transfer incoming calls to the selected agents. Additionally, the computer 
performs an outgoing call management function by initiating outgoing calls and 
causing the switch to connect an answering party to an agent, selected by the 
computer on any of the switches.

Filed: 1989-01-17
Abstract: A system for stopping the operation of a data processing system 
executing control words stored in a read/write control word 
storage device (2). A special control word is stored at the 
control storage address where it is desired to stop operation 
of the processor and the regular control word at that address 
is stored in a service processor memory (40). When the control 
storage address containing the special control word is reached, 
the special control word causes the system clock to be 
inhibited, thereby stopping the execution of control words, an 
indication that the processor has been stopped is generated, 
and the regular control word is restored to the control word 
storage device from the service processor memory for resumption 
of system operation.

Filed: 1990-02-28
Abstract: A self-routing switching system connected 
between input highways (10) and output highways (60), 
includes conversion modules (20), doubled SRM 
networks (30), output modules (50), 
and first and second 
selectors. Normally, one of the SRM networks is 
connected between the conversion modules and output 
modules through the first and second selectors. When a 
request to switch the active network to the other SRM 
network, the first and second selectors switch 
connections to the conversion modules and output 
modules so that the other SRM network is connected 
between the conversion modules and output modules. 
Before actually switching the connections, it is 
determined whether or not all cells have been 
discharged from the active SRM network.

IPC: G01N21/53
Filed: 1990-05-18
Abstract: In an air contamination level detector for 
detecting the degree of contamination of the intake 
air to an internal combustion engine, a laser beam is 
directed through the intake air stream and light 
scattered from particles in the intake air stream are 
detected by a photodetector to generate a pulse for 
each particle. Pulses over a given size are used to 
enable an AND gate to pass high frequency pulses to a 
counter, which is periodically recycled. The count 
accumulated in the counter represents the duty cycle 
of the pulses and the dirtiness of the intake air. 
When the count in the counter reaches a preselected 
level, it causes a warning light to be energized to 
indicate that the intake air has a exceeded a 
tolerance level.

Title: A communications system for data transmission over a time division duplex frequency channel
IPC: H04M1/733
Filed: 1990-05-22
Abstract: A communications system such as a digital cordless telephone 
system comprises primary (or base) stations (PS) and secondary 
stations (SS), the primary stations over a local area being 
coupled to a system controller (14 or 15) which interfaces with 
the PSTN. A TDMA method is used for forward and reverse 
transmissions between a primary and a secondary station. For 
digitised speech transmission normally one duplex voice channel 
formed by one forward time slot (or physical channel) and one 
reverse time slot (or physical channel) in each frame is 
allocated for the transaction. For fast data rates it is 
desirable that additional duplex voice channels be made available 
quickly for the transmission of a fast data message after which 
the additional duplex voice channels can be relinquished. In 
order to facilitate the rapid setting-up of a data transaction, a 
map store in each data secondary station lists the usage and 
quality of all the duplex voice channels and the secondary 
station, when ready to transmit data, immediately uses additional 
duplex voice channels from those listed, thus avoiding the 
necessity of scanning all the duplex voice channels before 
deciding on which additional duplex voice channels to attempt to 
transmit in.

Abstract: Silica gel chromatographic supports surface-modified by 
reaction with (R¹O) 3-m Si R² m  (CH₂)₃NH(CH₂CH₂NH) n H, in which 
R¹ is a C₁-C₅ alkyl, R² is methyl or ethyl, and m and n are 
independently selected from the integers 0, 1 or 2, and further 
modified chemically to produce reverse-phase character, markedly 
reduce the interaction between silanophilic analytes and the silanol 
groups present on the surface of the silica gel through the presence 
of polar groups, which include the residual unmodified amino and 
modified amino groups, and which are densely packed near the 
silica surface. This results in chromatographic elution of basic, 
silanophilic analytes in efficient, narrow bands similar to those of 
the less-polar analytes.
