Abstract: A circuit arrangement for supporting and monitoring a microcontroller, which is constructed externally of the microcontroller, comprises a watchdog circuit for monitoring the microcontroller, which circuit outputs an error signal if not reset by the microcontroller within a watchdog period, and an interrupt circuit, which feeds important system messages to the microcontroller as interrupt events for processing. In order correctly to combine interrupt processing and watchdog operation, the watchdog circuit is connected to the interrupt circuit and cooperates therewith in such a way that the interrupt circuit feeds at most a predetermined number of interrupt events to the microcontroller within a watchdog period.

Abstract: A device and method for storing information including an array of memory cells organized in bitlines and wordlines. The bitlines are subdivided in sections of wordlines and the sectioned bitlines are connected to a global bitline by a connector. The connector is made bidirectional and uses the high order part of the wordline addresses for this section of bitlines as a disable reset command. The reset stays active for unselected portions, compensating leakage of a mass of unselected cells which could disturb valid read signals.

Abstract: An electrical switch including a housing, four fixed contact elements fixed with respect to the housing, and four movable contact elements movable with respect to the housing. Each of the movable contact elements is positioned directly opposite from a respective fixed contact element. An actuating member is movable from a neutral position into four actuating positions. In each actuating position the actuating member actuates a respective movable contact element causing the respective movable contact element to contact a respective fixed contact element for enabling a corresponding switching function. An auxiliary frame surrounds the actuating member and is positioned within the housing. A first pair of opposed connecting elements connects the actuating member to the auxiliary frame. The first pair of opposed connecting elements form a first pivot axis. A second pair of opposed connecting elements connect the auxiliary frame to the housing.

The haptic signal generating device is developed in the form of a mechanical detent assembly including a detent curve and at least one detent element engaging the stop curve. An activating device is allocated to the haptic signal generating device and is actively configured on the detent curve or a detent element. By selecting the activation device an interaction is created between a detent element and the detent curve in order to generate the haptic signal formed by the detent curve. The haptic signal can be enabled or disabled by activating or deactivating the activation device as the control shaft is rotated.
