Patent number: 11168658Abstract: A method actuates a starter of an internal combustion engine by way of a starter relay. The starter relay is configured to supply the starter optionally with current via an on-board electrical system. The method has the following steps: determining an error status of the internal combustion engine; commencing repeated actuations of the starter relay; determining a current status of the internal combustion engine, wherein the current status of the internal combustion engine displays at least one error status or at least one operating status; and, if the current status displays at least one operating status, ending the repeated actuation of the starter relay, otherwise once again determining the current status.Type: GrantFiled: June 26, 2019Date of Patent: November 9, 2021Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Uemit Cansever, Peter Holt

Patent number: 5696921Abstract: A rotating memory system (e.g. a disk memory) in which a write request is allocated a physical block preferentially on the cylinder on which read/write heads are currently located. This reduces the amount of head movement and hence speeds up the access time. A block map is maintained to convert between the logical block numbers used by read and write requests and the physical block numbers which identify the physical locations of the blocks in the memory.Type: GrantFiled: November 15, 1991Date of Patent: December 9, 1997Assignee: International Computers LimitedInventor: Nicholas Peter Holt

Patent number: 5644746Abstract: A data processing apparatus, having a visible register map for associating physical registers with logical registers. Instructions involving register-to-register transfers are executed by altering the association between the physical registers and the logical registers, without actually transferring data between the registers, so as to avoid logically redundant operations and to take such instructions out of the critical path of execution.Type: GrantFiled: April 30, 1992Date of Patent: July 1, 1997Assignee: International Computers LimitedInventors: Nicholas Peter Holt, John Richard Eaton
