Patent number: 11902784Abstract: Systems and methods for access control systems includes first and second access facilities, and first and second readers. The first reader is configured to control access through the first access facility, receive a credential using a first communication protocol from a device that stores the credential, and establish a secret with the device using the credential. The second reader is configured to control access through the second access facility. The first reader is configured to provide the secret to the second reader, and the second device is further configured to perform ranging using the secret and a second communication protocol different than the first communication protocol to identify intent information. Access through one of the first facility or the second facility is coordinated using the intent information.Type: GrantFiled: March 24, 2020Date of Patent: February 13, 2024Assignee: ASSA ABLOY ABInventors: Hans-Juergen Pirch, Fredrik Carl Stefan Einberg, Tomas Lars Jonsson, Sylvain Jacques Prevost, Jan Steffl, Hans Gunnar Frank

Patent number: 6330701Abstract: The present invention relates to a method of utilizing information made available in a bit error check of data words belonging to instructions read into a processor having a first (11) and a second (11′) calculating unit which operate in parallel with one another, a so-called double processor mode. The processor structure also comprises a third and a fourth calculating unit (13, 13′) intended for continuously checking for possible bit errors in read-in data words, a comparator (14) for comparing output data from parallel operating units (11, 11′), a diagnostic unit (15) adapted to determine which of the calculating units delivered correct output data when detecting a difference in output data in the comparator (14), and a control unit (16) adapted to control that the output data from the processor structure (1) originates from a calculating unit that has delivered correct output data.Type: GrantFiled: December 9, 1998Date of Patent: December 11, 2001Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Michael Rosendahl, Tomas Lars Jonsson, Per Anders Holmberg

Patent number: 6279082Abstract: A method and system are described for improving memory access. The invention will improve memory access in systems where program code and data stored in memory have low locality. The invention builds on that the access to at least some addresses of the memory will take longer time than the access to other addresses, such as, for example, page type memory.Type: GrantFiled: October 14, 1998Date of Patent: August 21, 2001Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Lennart Michael Rosendahl, Tomas Lars Jonsson, Per Anders Holmberg

Patent number: 5828875Abstract: Loops in program code are avoided by generating instructions for controlling a processor. A first template instruction is stored, and a predetermined number of instructions may be generated, wherein each generated instruction is based on the first template instruction. The processor may be alternatively supplied with the generated instructions or with instructions received from an alternative instruction source. A substitute address field may be stored, and the step of generating each instruction may include substituting the substitute address field in place of an address field in the first template instruction. The stored substitute address field may be adjusted after generating each instruction. The step substituting the substitute address field in place of an address field in the first template instruction may be performed only if a substitution control signal is asserted.Type: GrantFiled: May 29, 1997Date of Patent: October 27, 1998Assignee: Telefonaktiebolaget LM EricssonInventors: Dan Olov Halvarsson, Lars-Erik Lundstrom, Tomas Lars Jonsson, Tobias Carl Roos
