Title: Error detection and correction system
IPC: H03M13/27
Filed: 1979-05-08
Abstract: In an EDAC system, words to be encoded are partitioned, by interface 10, into 2 interleaved field of odd and even bits. Each field is separately encoded, at 11 and 12, and the encoded fields are interleaved at 13. For decoding, the encoded word is partitioned, at 14, and each field is decoded (16, 17) and corrected (20, 21) before interleaving at 24 to reproduce the original word. Greater immunity to errors bursts is achieved. Further, a cyclic redundancy code (CRC) check is used (25, 26) for additional error detection, using an polynomial f[g(x)] which is chosen as a factor of the EDAC generator polynomial g(x). The same check bits in the code word are thus used for both the EDAC check and the additional CRC check. <IMAGE>

Patent GB-2038132-A (GB)
Title: Distance indicating system
IPC: G01S13/931
Filed: 1979-11-12
Abstract: A distance indicating system, particularly for a vehicle, includes a transmitter 8 to transmit a signal beam, and two receivers 10 and 12 one on either side of the transmitter 8. The transmitter and the receivers are mounted on the front of a vehicle, and if an object 24 is directly in front of the vehicle the transmitted signal beam will be reflected by the object 24 and received simultaneously by the receivers 10 and 12. A coincident gate 16 is actuated only in response to signals received simultaneously by the receivers 10 and 12, and the actuated gate 16 sends an output signal to an echo delay measuring circuit 18. This circuit 18 operates an audio tone generator 20 and an audio output indicator 22 thereby providing an aural warning for the vehicle driver of the presence of the object 24. A clock 14 switches the transmitter 8 and the receivers 10 and 12 on and off in a suitable sequence to prevent a transmitted signal being passed directly from the transmitter 8 to the receivers 10 and 12 and being passed to the coincident gate 16. The audio output 22 is not operated in response to signals reflected from objects to the left or right of the vehicle because the reflected signals do not arrive simultaneously at the receivers 10 and 12, and consequently the coincident gate 16 is not actuated. <IMAGE>

Patent GB-2039106-A (GB)
Title: Number format conversion in computer Fig 3A
IPC: G06F12/04
Filed: 1979-12-31
Abstract: A pure binary number of up to 4 characters, each of 8 or 9 bits, is stored in adjacent bytes in the memory of a machine using 4-byte words, with 9 bits per byte. To read the number from memory into an addressable register RX0-RX7, RA or RQ in a form suitable for arithmetic, the word (or the 2 words) storing the number are read into a data in register RDI. A byte-wise left shift by a shifter SHF left justifies the byte of the number into an intermediate register RIM, then the appropriate position of a format switch 52 is selected to right-justify the number as it enters the addressable register, to pack the characters together if necessary, and to sign extend the number if desired. The reverse format switching and shifting is performed to store the number back in memory. A 1 or 2 character number can also be right- justified to a half-word boundary.
