Title: Signal combining circuitry
IPC: H04N5/20
Filed: 1989-04-28
Abstract: A signal combining circuit for adaptively 
combining first and second signals includes a comparator to 
develop a control signal to indicate when the combination 
of the first and second signals will have an amplitude 
exceeding a predetermined amplitude in one polarity sense.

signal the first signal is combined with a further signal 
related to the first signal and a reference value.

Patent EP-0433699-A3 (EP)
Title: Circuit arrangement for communication devices with asynchronous transfer mode
IPC: H04L12/56
Filed: 1990-11-23
Abstract: When a new virtual connection is set up via an ATM line, a check is carried out to ascertain whether the still available free transmission power is adequate for the transmission power required for the virtual connection which is to be newly set up. Every subscriber reports in advance its mean bit rate and its peak bit rate, which values must not then be exceeded. When a new connection is set up, the new total load is calculated from the mean bit rates and the peak bit rates. This is compared with the relevant overall peak bit rate which is permissible for the ATM line concerned; the required new virtual connection is set up only if said total load does not exceed said overall peak bit rate. The calculation entails subtraction, multiplication, addition, root extraction and further technically implemented operations. <IMAGE>

Title: Multiprocessor data processing system
IPC: G06F9/44
Filed: 1990-04-27
Abstract: A parallel declarative data processing system 
comprises a number of data processing elements. A

locality annotations, which specify the preferred 
locations for executing the expressions. These 
annotations are used to route the packets to particular 
processing elements. Thus, for example, it can be 
arranged that a specified set of expressions will all be 
executed on the same processing element.
