Title: Routing apparatus and method for high-speed mesh connected local area network
Inventor: THACKER CHARLES P
IPC: G06F15/173
Filed: 1990-03-02
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.

Patent CA-2017757-A1 (CA)
IPC: G09G3/36
Filed: 1990-05-30
Abstract: A frame thinning out system has been used as a display driving method for making a gradational display with several brightness levels on the screen of a liquid crystal display device and the like.  A display driving method of the present  invention,  sets  a plurality  of  frame time periods,  during which each of pixels on the screen is controlled to display an image,  as one integration time period.  Pixels are turned on only for a number of specified frame time periods corresponding to the desired brightness level.   In this driving method the pixels of the display device are grouped into groups of a plurality of pixels contiguous to each other, the number of pixels to be turned on in each frame time period is selected corresponding to specified gradation data within the same group, so that the number of pixels to be turned on for one frame time period may be equal between subgroups in the scanning lines within the same group, and the frame time period is set to a period so short that a human does not feel flicker.  In this way, a group of pixels as a unit image area,  a gradational display without noticeable flicker can be obtained.  Since no delicate shades of brightness occur among pixels to the same  gradation  level,  the  quality  of  the  display  is improved.
Patent CA-2019131-A1 (CA)
Inventor: STERLING EDWARD W II
IPC: G06F15/177
Filed: 1990-06-15
Abstract: The  method  of  this  invention  comprises  an  efficient technique   for   transfer   of   information   over   a communication link between first and second processors, the processors employing blocks of data on a repetitive basis.  Each processor includes means for storing copies of used blocks of data.  A block of data currently used (or displayed) in the second processor is called an "old" data block and a block of data to be transmitted from the first processor to the second processor is called "new" data block.   The method includes the steps of storing identical copies of used data blocks and the old data block in the memories of the first and second processors. The  new  data  block  is  then  compared  in  the  first processor to stored data block copies to determine if the new  data  block  equals  a  pre-established  level  of similarity with any of the stored data block copies.  If a stored data block is found to equal the pre-established level of similarity with the new data block, the method contemplates  transmission  to  the  second  processor  of information regarding the differences between the new data block and the similar stored data block, as well as the  identity  of the  similar stored data  block.   The second processor then proceeds to access its copy of the identified similar stored data block and to alter that data block in accordance with the difference information transmitted from the first processor.

Abstract: A sports device comprising an elongated support having a handle thereon for gripped engagement by an individual to impart a tilting motion to the elongated support. A removable weight shifting means is mounted at one end of the elongated support for changing the balance point of the elongated support responsive to the tilting motion. A concave track is supported on the elongated support and is provided at its opposite ends with a ramp disposed in inclined relation relative to the track. A ball is provided for placement in the track and is disposed for controlled rolling movement therealong responsive to the tilting motion. A ball ejecting member is mounted at the end of each ramp and each such member includes an angled surface for impact by the ball and ejection thereof from the elongated support responsive to the ball exceeding a predetermined speed as a result of excessive tilting motion of the track. Indicating means are provided for signaling when the elongated support has "safely" been tilted to a predetermined limit (for one round trip of the ball without the ball being ejected) resulting in a score. The indicating means also signals when the predetermined tilt limit has been exceeded resulting in a "foul". In an alternative arrangement, the ball is controlled to drop through a hole in an inclined track for "bombarding" a target located below the hole for a "score". A "foul" is indicated when the tilting motion exceeds a predetermined limit as discussed above.

Inventor: MCAULEY ANTHONY J
IPC: G06F11/10
Filed: 1991-02-25
Abstract: In accordance with an inventive Forward Error Correction (FEC) code, data is transmitted in codewords comprising n m-bit symbols. Of the n symbols, k symbols are known information symbols and h symbols are parity symbols for erasure correction. All of the symbols of the codeword are elements of a field of 2m integers which is closed with respect to addition and multiplication such as a Galois field. To determine the h parity symbols, an encoder circuit (17) derives a matrix corresponding to a set of simultaneous equations in terms of the k known information symbols and the h parity symbols. This set of equations is then solved for the h parity symbols so that a codeword is transmitted comprising k known information symbols and the h known parity symbols. At a decoder (19), the values of up to h erased symbols in the codeword may be reconstructed using a similar set of simultaneous equations.
