Title: Bandwidth reduced multi-pass writing of variable gray level digital images
IPC: H04N1/40
Filed: 1989-12-21
Abstract: User-viewable renderings of variable gray level images composed of pixels represented by 
binary coded codewords are written on a suitable recording medium by one or more pixel 
generators which have their write responses code matched to the codewords. More 
particularly, the write responses of the pixel generators (22 a -----) are "code matched" to 
the codewords by cyclically and bit synchronously stepping them through a series of gray-­
scale values which are selected to substantially match the binary weights of the respective 
bits of the codewords. Such code matched pixel generators are selectively write enabled 
and disabled in response to the logic levels of the successive bits of the codewords that are 
applied to them, whereby the binary weighted writes any of them performs in response 
to a given codeword spatially sum to form a pixel having approximately the same gray-­
scale value as the given codeword.

Title: Interleaving circular buffers
IPC: G06F12/06
Filed: 1989-10-10
Abstract: Method and apparatus for managing a plurality of circu­
lar buffers are disclosed. The method subdivides a con­
tiguous block of storage into a plurality of interleaved, 
circular buffers. The storage area is divided into N, M 
length circular buffers that are interleaved. The inter­
leaving technique starts each of the M buffers at address 
I-1, where I is the buffer number (1,2,3,4).  
     Additional subdivisions of an allocated circular 
buffer of length N are formed by evenly dividing an exist­
ing circular buffer into K additional buffers of length L 
(note that K * L = M). For example, 2 additional buffers 
of length 2 are allocated from the above sixteen byte 
memory starting with the first K elements of one of the 
four byte original circular buffers. The increment to get 
to the next element in each buffer is K * M. The address 
of the Qth element of the buffer is Q * K * M + A(i), 
where A(i) is the starting address of the buffer that is 
being subdivided.

Abstract: The printing machine has two multi-color printing units (I, II) of essentially identical construction, each composed of a first blanket cylinder (4, 14), of a second blanket cylinder (7, 17), of a plate cylinder (5, 15) and of an image transfer cylinder (6, 16). In the offset-printing position, the second blanket cylinder (7, 17) inked by offset plate cylinders (8) rests against the first blanket cylinder (4, 14), while in the collect-printing position it is moved away from this and inked by color selector cylinders. In the collect-printing position, the plate cylinder (5, 15) carries a collect-printing plate, of which the image inked by the first cylinder (7, 17) is transferred to the first blanket cylinder (4, 14) via the image transfer cylinder (6, 16). In the offset-printing position, the plate cylinder is inoperative. Furthermore, in the two printing positions, the image transfer cylinder (6, 16) interacts with the plate cylinder (10, 20) of an additional single-color printing unit, the image of which is likewise transferred to the first blanket cylinder (4, 14). The paper runs between the first blanket cylinders (4, 14), pressed against one another, of the two printing units and receives a simultaneous recto-verso print. The plate cylinder can also rest against the first blanket cylinder and in the offset-printing position, with the image transfer cylinder moved away, belong to the additional single-color printing unit.

Title: Catheter and method for locally applying medication to the wall of a blood vessel or other body lumen
IPC: A61F2/958
Filed: 1990-01-16
Abstract: A method and catheter for use in practising the 
method are provided by which a highly concentrated 
medication or chemotherapeutic agent can be applied 
locally under sufficient pressure to cause the 
medication or agent to penetrate into the localized 
tissue. The total volume of medication or agent is 
quite small, well below levels that might cause an 
adverse reaction in other parts of the body. The 
catheter includes a thin walled flexible balloon (16) 
having a plurality of minute holes (29) through which 
medication may flow at a low flow rate. The balloon (16) 
is inflated with the medication under pressure and 
the low flow rate of the order of a few ccs per 
minute is controlled by the minute holes (29) in the 
balloon (16). In practising the method of the invention, 
the balloon (16) is selected such that its inflated 
diameter will correspond to or be slightly greater 
than the diameter of the lumen into which it is to 
be placed so that when the balloon (16) is inflated, it 
will contact intimately the surface of the lumen. 
Inflation of the balloon (16) with the medication will 
cause a thin film to spread between the balloon (16) and 
the lumen, the film being maintained under a 
sufficient pressure to penetrate significantly the 
surrounding tissue with a high concentration of 
medication. The quantity of medication that 
ultimately flows free into the lumen is quite small 
and is insufficient to cause any other damage to the 
patient.

Patent EP-0404339-A3 (EP)
IPC: G06F15/173
Filed: 1990-05-17
Abstract: A packet routing apparatus allows numerous packets to be 
routed simultaneously through a mesh connected network. 
The network consists of a number of interconnected 
switches which are coupled, in turn, to the hosts that are 
members of the local network. The switches are nonblocking 
switches that are coupled to each other and to the hosts by 
a multiplicity of point to point links. Each switch has a 
routing mechanism for automatically routing received 
packets toward their specified destinations. For each 
received packet the router generates a routing mask 
representing the output links that may be used to route the 
packet towards its destination. The routing mask includes 
a broadcast bit. If the broadcast bit is ON, the packet 
must be simultaneously routed to all of the output links 
specified by the routing mask. If the broadcast bit is 
OFF, the packet may be routed on any single one of the 
links specified by the routing mask. To ensure that every 
packet makes progress towards its destination, packets are 
processed in the order of their arrival by placing the 
corresponding routing masks in a queue. Periodically, the 
set of available output links is compared with all of the 
routing masks. Using a first come, first considered 
routing discipline, the first routing mask in the queue to 
match the available output lines is selected. A routing 
selection is then generated for the corresponding packet 
and the selected routing mask is removed from the queue.
