Abstract: Disclosed are various embodiments for implementing automatic firmware rollbacks after a configured number of attempts to execute the latest firmware update associated with an electronic computing unit have occurred. In a computing device, such as an electronic computing unit, a watchdog automatically generates a system reset in response to a software fault. A reset counter is configured to count a number of system resets generated by the watchdog. In response to the occurrence of the watchdog, a configurable threshold value associated with a threshold data record is compared with the value associated with the reset counter. In response to a determination that the threshold value associated with the threshold data record is greater than or equal to the value associated with the reset counter, a rollback application is executed such that the rollback application performs a swap of a first version of a firmware with a second version of the firmware.

Abstract: A press assembly has a plurality of processing stations for the processing of sheets. These processing stations are arranged in succession in a transport direction of the sheets for inline processing of the sheets. At least one of these processing stations is a non-impact printing unit and at least one processing station downstream of the non-impact printing unit is embodied as a dryer. At least one additional processing station is embodied as a coating unit. The coating unit is configured for applying a coating in a form of a varnish to each sheet. A plurality of individually controlled, non-impact printing units are arranged along the transport path of the sheets. Each of the plurality of non-impact printing units is configured as an ink jet printer.

Abstract: A printing press arrangement has a plurality of processing stations for processing sheets. The plurality of processing stations are arranged one after another in a transport direction of the sheets for in-line processing of the sheets. At least one of the processing stations is configured as a non-impact printing device. A transfer device, which is arranged upstream of the active region of the non-impact printing device, is provided for transferring the sheets from a first processing station, which is arranged upstream of the non-impact printing device, to the non-impact printing device. The transfer device aligns, in each case, at least one of the axial register and the circumferential register and the diagonal register of each of the sheets in register relative to the printing position of the non-impact printing device.

Abstract: Pre-fetching instructions for tasks of an operating system (OS) is provided by calling a task scheduler that determines a load start time for a set of instructions for a particular task corresponding to a task switch condition. The OS calls, and in response to the load start time, a loader entity module that generates a pre-fetch request that loads the set of instructions for the particular task from a non-volatile memory circuit into a random access memory circuit. The OS calls the task scheduler to switch to the particular task.

Abstract: An embedded computer system includes a processor, an interrupt source, an interrupt controller and a cache memory subsystem. In response to a request from the processor to read a data element, the cache memory subsystem fills cache lines in a cache memory with data elements read from an upper-level memory. While filling a cache line the cache memory subsystem is unable to respond to a second request from the processor which also requires a cache line fill. In response to receiving an indication from an interrupt source, the interrupt controller provides an indication substantially simultaneously to the processor and to the cache memory subsystem. In response to receiving the indication from the interrupt controller, the cache memory subsystem terminates a cache line fill and prepares to receive another request from the processor.

Abstract: A task control circuit maintains, in response to task event information, a task information queue that includes task information for a plurality of tasks. Based upon the task information in the task information queue, a future task switch condition is identified as corresponding to a task switch time for a particular task of the plurality of tasks. A load start time is determined for a set of instructions for the particular task. A pre-fetch request is generated to load the set of instructions for the particular task into the memory circuit. The pre-fetch request is forwarded to a hardware loader circuit. In response to the task switch time, a task event trigger is generated for the particular task. The hardware loader circuit is used to load, in response to the pre-fetch request, the set of instructions from a non-volatile memory into the memory circuit.

Abstract: A method and machine arrangement for sequential processing of sheet-like substrates are disclosed. At least one of a front side and a rear side of the substrates is processed in a production line one after another. A printing ink or another type of ink is applied in at least one non-impact printing device on the respective side of the substrates. The printing ink or the other type of ink is dried. A dispersion coating or a coating cured by UV radiation is then applied onto the respective side of the substrates. The dispersion coating or the coating cured by UV radiation is dried and the substrates are fed to a mechanical processing device for carrying out a further mechanical processing of the substrates. The further mechanical processing is performed by at least one of punching, inserting grooves, separating parts and by breaking out panels from their respective composite in the respective substrate.

Abstract: The invention relates to a method and a device for arranging sheets in an overlapping position in a transfer unit arranged between a first processing station and a second processing station following the first processing station in a transport direction of the sheets. The sheets to be overlapped are transported from the first processing station to the transfer unit, in a transport plane and each individually lying behind one another. A respective rear, in the transport direction, edge of the sheets coming from the first processing station, is raised relative to the transport plane exclusively by the use of blown air, and a second subsequent sheet is slid under the rear edge of the respective preceding first sheet.
