Patent EP-0334503-A3 (EP)
IPC: H04L9/32
Filed: 1989-03-06
Abstract: An encryption apparatus has a keyboard 1 for the input of 
message data and a processor 2 for encrypting that data 
under a working key. The working key is not, however, 
permanently stored in the apparatus. Rather, the working 
key is derived by encrypting "precursive key data" stored 
in a memory 5 of the apparatus under a key represented by, 
or derived from, a password input  via  the keyboard, and is 
erased after each use. In this way, the secrecy of the 
working key is not dependent on maintaining the ultimate 
physical security of the apparatus against possible 
attempts to gain access to its memory, but rather on the 
secrecy of the password which is input to the apparatus 
only as and when it is necessary to derive the key for 
performing the encryption process.

Title: Power supply circuit
IPC: H02M1/12
Filed: 1989-03-28
Abstract: A load is supplied by transformer 10 supplied via a voltage regulator and thyristor network. The thyristor network and regulator are simultaneously controlled to respond to changes in the load and in practice the thyristors respond rapidly and are re-adjusted as the regulator is inherently more slowly adjusted. The result is that the thyristors produce minimum reflected harmonics overall in the mains and an optimum power factor can be achieved for each power setting.

Title: Method for accessing data in a table and its application to the routing of data between remote stations
IPC: H04L12/46
Filed: 1989-10-20
Abstract: The present invention relates to the accessing data in 
tables and its application to apparatus for providing 
a communication bridge interconnecting two or more 
local area networks (LAN).  
     A LAN (1) is connected to another LAN 2 by means of a 
bridge generally designated by the numeral (3). Input 
buffers (11, 21) forward packet headers of received 
data packets through to a routing engine (5). The 
routing engine (5) contains one or more routing tables 
each having a plurality of table locations containing 
table data in the form of station addresses and 
routing data. The table is accessed by applying a 
hashing algorithm to a received destination address 
contained in the data packet to determine the table 
location and then checking that the station address 
retrieved from the table location corresponds with the 
destination address in the received data packet. If 
the table location is empty or the destination address 
does not match the station address, the data packet is 
forwarded to all interconnected LANs. Otherwise, the 
data packet is forwarded according to the retrieved 
routing data. Embodiments are described wherein the 
table locations are over-written by applying the 
hashing algorithm to the source address of a received 
data packet and writing in at the resultant table 
location the source address and routing information of 
the received data packet. A time stamp can also be 
written at this time so that obsolete data entries are 
not employed for routing.

Patent EP-0671822-A3 (EP)
Inventor: DOSTERT KLAUS PROF DR
IPC: H04L5/14
Filed: 1995-03-06
Abstract: On reception, a filtered and amplified reception signal (X) coupled from the current network, reaches a digital multiplier (5) after digital to analog conversion. The second input of the multiplier has a reference signal (Y) from a sample value memory (24) addressed by a cyclic address counter to fixed base length (20). Exactly four reference values (Y), corresponding to the in-phase and quadrature sample values of each L and H signal form, are allocated to each X value. The resulting products are accumulated in a ring structure of a summer (6), four registers (7,8,9,10) and a switch (11). After one signal form cycle, the in-phase components of the H and L bit are accumulated in two registers (9,10) and the quadrature components are accumulated in the other registers (7,8). By undoing the ring structure, the switch (11) feeds the four results from the registers (7-10) to a decision unit including a switch (13), a summer (14) and two registers (15,16).
