Abstract: A method for scheduling tasks to a cyclic schedule, comprising maintaining a request queue, a count, the count being initialized to a given limit, and an index of a current time slot within the schedule. Periodically, if the request queue contains a reference to an urgent task among the tasks, that reference is removed from the request queue and the urgent task is dispatched and if the request queue is empty, the index is advanced to the next time slot within the schedule. If the next time slot is statically assigned to a task among the tasks, that task is dispatched, and if the next time slot is unassigned and the count is below the limit, the count is incremented and the index is further advanced to the next but one time slot.

Abstract: A method for securing an application programming interface of a utility program library, including at least one program construct, of a hypervisor, including a configuration of the hypervisor that assigns at least one permissible call of the program construct to at least one guest system of the hypervisor, and a code generation, supported by the configuration, of a declaration of the program construct adapted to the guest system.

Abstract: A method for creating a hypervisor unit for a control unit is described. The hypervisor unit is designed to execute two applications on the control unit during a run time. The hypervisor unit is created during a compile time as a function of a first property of the first application, as a function of a second property of the second application, and as a function of a third property of the control unit.

Abstract: A method for protecting a working memory, including the following features:—memory areas of the working memory are optionally assigned to a first class or a second class; prior to a program execution, at least the memory areas of the first class are entered into a configuration table of the memory protection unit; and when access to a destination area among the memory areas of the second class is requested during the program execution, the destination area is entered into the configuration table before the access is granted.

Abstract: Method for hosting a multitasking guest on a host system, wherein the guest is allocated a periodic execution server and a deferrable execution server associated with a partition of the system, event-driven tasks of the guest are assigned to the deferrable execution server, time-driven tasks of the guest are assigned to the periodic execution server, a hypervisor of the execution servers is assigned to a first priority group of the system, the deferrable execution server is assigned to a second priority group of the system, the periodic execution server is assigned to a third priority group of the system, and a preemptive task scheduler maintains a descending priority order among the priority groups while the execution servers execute the tasks concurrently.

Abstract: A method for the on-board diagnosis of a control unit which include a hypervisor and at least one guest system operated under the hypervisor. In the method, the guest system receives a diagnosis inquiry at an individual diagnosis address of the guest system from a diagnostic tool with the aid of a communication infrastructure. The guest system makes a self-diagnosis. The guest system receives a hypervisor diagnosis from the hypervisor. The guest system transmits, at its diagnosis address, the self-diagnosis or the hypervisor diagnosis to the diagnostic tool as a function of the diagnosis inquiry.

Abstract: A method for creating a hypervisor unit for a control unit is described. The hypervisor unit is designed to execute two applications on the control unit during a run time. The hypervisor unit is created during a translation time as a function of a first property of the first application, as a function of a second property of the second application, and as a function of a third property of the control unit.

Abstract: A method for updating a virtual machine operated under a hypervisor on a physical machine having a random-access memory and a read-only memory. The hypervisor operates the virtual machine under an individual diagnostic address, the read-only memory storing a machine code of the hypervisor and of the virtual machine. The virtual machine receives an updating request from an external unit under the diagnostic address with the aid of a communication infrastructure and communicates the updating request to the hypervisor, The hypervisor transfers the machine code from the read-only memory into the random-access memory. The hypervisor starts the virtual machine and executes a boot manager of the virtual machine. The boot manager receives a current machine code under the diagnostic address of the virtual machine and exchanges the machine code in the read-only memory at least partially for the current machine code, and the boot manager restarts the virtual machine.

Abstract: Method for monitoring a control flow of an imperative computer program, including annotating scheduling the program with calls to a monitor, each call by a thread indicating the thread, scheduling the program and the monitor for execution by an operating system, and, scheduling upon receiving the call, the monitor verifying the thread by means of the operating system.

Abstract: A method of bypassing an AUTOSAR software component of an AUTOSAR software system including two or more AUTOSAR software components connected via a runtime environment (RTE). To get a high flexibility and a close relationship to the AUTOSAR model of development an custom AUTOSAR software component is used to bypass all or part of the functionality of a selected AUTOSAR software component and provide that functionality to another AUTOSAR software component candidate or on some external system.

Abstract: This invention relates to a portable odor scrubber system that is inserted into a sewer manhole or lift station where vaporous odors are prone to escape into the external environment. The invention controls such odors which may be caused by hydrogen sulfide, ammonia, mercaptan and other vapors which smell bad and can pose a severe health hazard. The invention has an automatic gas sensor trigger mechanism to control a fan to pull the noxious fumes through a series of scrubbers and to discharge treated air into the environment. Scrubber units may be easily replaced as well as designated to treat different environmental conditions. The invention can also store and transmit gas data information to an offsite location to monitor conditions where the portable odor scrubber system is located.
