摘要:
A method for monitoring the execution of a program executable on at least one microprocessor of a micro controller using a debug logic of the micro controller, with an exception, particularly an interrupt of the program execution, being triggered by the debug logic upon access to a specific address range during the program execution time. In order to provide monitoring of the execution of a program, executable on a microprocessor, for faults, which is particularly reliable yet conserves resources as much as possible, it is suggested that the debug logic be configured by the microprocessor and that an exception routine be executed by the debug logic after an exception has been triggered during the program execution time. The debug logic is advantageously configured during the startup of the micro controller. Preferably, the micro controller is reset and started up again and the monitored program is initialized during the execution of the exception routine.

A method of protecting a microcomputer system against manipulation of data stored in a memory arrangement of the microcomputer system, in particular a control program stored there. Checking mechanisms are executed at preselectable points in times to check for manipulation of the data. To permit effective blocking of manipulated data stored in the memory arrangement, new data is stored at least partially in a volatile memory, in particular in a random access memory, in reprogramming or new programming of the memory arrangement, the checking mechanisms are executed and the portion of the new data stored in the volatile memory is copied to the memory arrangement if no manipulation of the new data has been detected.

A method of controlling wireless messaging between mobile apparatuses and an onsite office in a worksite comprises the steps of: dividing the worksite area into elementary cells (C) mapped in correspondence with the topology of the area and into and communication zones (CZ), for a given communication zone of the worksite, establishing at least one updatable communication attribute value pertaining to a parameter of wireless communication to or from the given cell or communication zone, for a given elementary cell, establishing at least one worksite management attribute value of the worksite at that cell, the worksite management attribute value pertaining to a parameter other than a wireless communication parameter, storing, in an electronic memory (20), values of the worksite and communication attributes, each stored attribute value being electronically indexed to the elementary cell, or to the communication zone, for which it was determined, forming a worksite management message with an electronically readable content containing at least one worksite management attribute value, accessing the memory to obtain at least one current communication attribute value in respect of a cell or communication zone to or from which the formed management message is to be communicated by a wireless communication, and establishing a wireless communication to or from the communication zone to send or receive the management message on the basis of the current communication attribute value(s) electronically accessed from the memory.

摘要:
The invention relates to a device for opening and closing a movable furniture part, in particular a drawer (1), door, leaf, or the like, whereby the movable furniture part (1) may be locked and released, and may be pressed in by a specified distance and then extended. According to the invention, the device has at least one locking element and at least one push-out element which is separated from the locking element. The invention further relates to a furniture part having such a device.

The invention concerns a drawer slide with compensation of synchronous running errors of slide rails (equalize the errors of the relative positions of the slide rails to each other), having on each of the two side of the drawer a rail system, that has a cabinet rail fastened directly or indirectly by a cabinet angle on a cabinet body and is held directly or indirectly linearly movable by a linear bearing by a center rail on a drawer rail, which is connected directly or indirectly by a décor with the drawer; whereby a compensation mechanism is provided that has a compensation lever, that is connected by a pivot bearing directly or indirectly by a cabinet angle or linear bearing or décor with one of the rails, and during its turning at the end of each drawer closing cycle, reaches a positive/form-fitting position with stops, that directly or indirectly are connected by a cabinet angle or linear bearing or décor with the remaining rails and, thus, ensures each drawer closing is automatic, guided and has equalized any synchronous running error.
摘要:
Operations in a worksite (20) are managed by networking at least some items of apparatus (4, 16, 24, 26, 30, 28, 34) which perform tasks in connection with said worksite and which receive and/or send data. The items of apparatus are organized in hierarchical levels according to a determined dependency relationship of the worksite. Communications are made with an electronic data network comprising management means (74, 76, 66, 64) cooperating with a plurality of communications interfaces (42-46), a given item of apparatus having a data link with a specified communications interface. The management means stores a correspondence between each item of apparatus and an address strcture reflecting the hierarchical position of that item of apparatus (4, 16,24, 26, 30, 28, 34) in the determined dependency relationship of the worksite. It uses that correspondence to establish a communications link with a selected item of apparatus, via its communications interface, in response to a call addressed with an address structure reflecting the hierarchical position of that selected item of apparatus.
摘要:
A guidance system for manually guided vehicles such as reach stackers or straddle carriers is disclosed. In accordance with the disclosure, the position of the vehicles is permanently automatically detected and supplied to a guiding system for carrying out. Starting from transport job lists made available externally, the travel jobs are assigned to the individual vehicles in an optimized form. Suitable travel routes for the travel jobs are determined and the travel jobs, including the travel routes, are automatically transferred to the vehicle operators. Their carrying out is monitored.

The present application relates to a telescopic loader, in particular a reach stacker, consisting of a. vehicle frame, wheels arranged thereon, an engine and a telescopic boom pivotably arranged thereon with a load receiving means. The wheels can be driven by a hydrostatic drive which can be controlled via an undercarriage control with the undercarriage control having sensors for the detection of the actual states. In one example, it is advantageous to use a fuzzy logic unit to determine the rules of the driving property in dependence on a control command in combination with downstream controllers via which the commands can be directed on to the controlling elements of the hydrostatic drive.
