Title: Descrambling system for television signals scrambled by active line rotation
Inventor: ROBINSON ADRIAN PAUL
IPC: H04N7/169
Filed: 1989-07-11
Abstract: A descramble for descrambling a signal scrambled by active line rotation (i.e. by interchanging two portions of a line, Fig 1) has a pair of line stores 8 connected to a descrambling control input 13 (receiving data on the cut point between the two portions) to effect the line rotation. A tilt measurement circuit 3 measures line tilt, namely any overall change in video amplitude level across a line, and compensates by generating 4 a converse ramp signal which is added 5 to the video signal. The ramp signal is generated to ten-bit accuracy whereas the video signal has only eight bits. The two least significant bits are accumulated 6, 7 on a sample-by-sample basis to effect error feedback. The beginning and end of the received line comprise overlapping signal portions, and the tilt measurement is effected by comparing the overlapping signal portions. Instead of simply averaging the samples in each of these portions a low-pass filtering function is applied to reduce the effect of noise, the filter coefficients being stored in a store 22 and applied to a multiplier 21. <IMAGE>

Title: Haemodialyser unit
Inventor: SHIBATA TAKESHI
IPC: A61M1/16
Filed: 1993-03-24
Abstract: Blood guided out of the artery of a patient by a blood pump is introduced into an arterial inlet in blood flow direction changeover means, and it is then guided from its outlet to a dialyzer through an inlet therein. The blood then leaves an outlet in the dialyzer, enters the blood flow path changeover means, leaving a venous outlet and returns into the vein of the patient. The dialytic liquid, on the other hand, leaves a dialytic liquid outlet, passes through dialytic liquid flow direction changeover means and is finally discharged through a dialytic liquid outlet. Then, the respective changeover means are changed over to reverse the respective flows to each other. This is intermittently repeated. Thus, blood coagulation can be inhibited or prevented. <IMAGE>

Title: Synchronisation of time-of-day clocks in a distributed processing network system
Inventor: EDBLAD WARREN ALBERT
IPC: G06F13/00
Filed: 1993-06-16
Abstract: The operating system clocks in each station 3a-3d on a counter-rotating ring network 5 of a distributed processing system are synchronized by latching the count in a free running counter in the network interface of each station at the instant a clock message transmitted by a timekeeper station is received. The timekeeper station then calculates from its operating system time-of-day (TOD) clock and its free running counter, its time of reception of the clock message, and broadcasts this time to the other stations. Each other station calculates its own time of reception from its operating system TOD and the count in its free running counter, and uses the difference between its time of reception and the timekeeper time of reception to correct its operating system TOD clock. Repeater and media propagation delays determined from the dynamic topography of the network are taken into account in calculating the correction factor. The free running counter can also be used to maintain a higher resolution local time of day than is available from the operating system TOD clock. <IMAGE>
