Abstract: For accomplishing an interruption-free power supply operation of a system unit (HDD) in a computer system with a plurality of system computers (Sa; Sb) sharing the system unit (HDD) without having the limitation to a local location, a method and an arrangement is [sic] proposed in accord wherewith the operation of the respective station computers (Sa; Sb) respectively ensues with their own interruption-free power supplies (USVa; USVb) and, for the power supply of the shared system unit (HDD), the shared system unit (HDD) is always connected to an active interruption-free power supply (for example, USVb) by an automatically switching switchover (PCS) that monitors the voltage of its inputs.

Abstract: A new operating system is provided with two layers having different access authorizations. For security reasons a memory for basic system routines can be accessed only from a kernel layer, but not from an application layer. By providing a respective program that is executable in the respective layer, it is possible, while complying with the security stipulations, for the memory to be accessed and, consequently, for a new version of the basic system routines to be made available to the data processing system.

Abstract: Given a CD-ROM drive having a plurality of speed ranges selectable in n-fold graduation and having linearly reduced rotational speeds within each speed range respectively between outer and inner sector and having the prescription that a reduction of the rotational speed automatically ensues given a negative read result, control means are provided that effective switching into a lower speed range when a predetermined noise level is upwardly transgressed and/or when vibrations occur.

Abstract: A power supply unit for a computer system is proposed which has at least one data memory unit, which provides data specific to the power supply unit, for system controllers in the computer system. This achieves the object of offering the capability of ensuring that the power supply unit is not overloaded or underloaded, or that an appropriate message is output to the outside world, without having to explicitly know all the possible operational situations even in the development phase of the power supply unit.

Abstract: A portable orientation system which, when for example the human sense of vision fails, can make information gathered from the surroundings available to another human sense. The portable orientation system has a sensor unit for selectively sensing information on the surroundings which is normally sensed by human senses. A signal processing unit is connected to the sensor unit and processes the signals of the sensor unit. A control module controls sensing options and/or processing options and/or output options of the sensor, the signal processing unit and the output unit. The portable orientation system further includes a power supply unit.

Abstract: The invention relates to a method for the provision of a device code for an electronic device, which is at least required for the first commissioning of the device code, whereby the device is inoperable without the input of the device code. The method is characterized in that the following procedural steps are carried out: Storage of a device number and an appropriate device code in a database, delivery of the device to a further processing site and readout of the device code stored in the database in conjunction with the device number, whereby the previous or simultaneous storage of a selected code number in the database in conjunction with the device number is required for readout.

Abstract: The invention relates to an apparatus for fixing a slot angle (5) to the slot field (2) of a computer housing (1). According to the invention, the slot field (2) is adjusted to the geometry of the slot angle, which means that by closing a cover (9) of the computer housing (1) the slot angles (5) are automatically fixed by way of clamping action.

Abstract: A notebook computer has a basic body comprising a bottom shell and a top shell. A display unit is arranged in a pivotable lid housing and a keyboard is detachably mounted on the top shell. A cutout is provided in the top shell and an outwardly directed electrical contact configuration is secured on an assembly that is attached to the basic body such that the contact configuration is secured in the cutout. The contact configuration is for electrically contacting the keyboard, which has a corresponding mating contact configuration.

Abstract: The invention relates to a communication unit (3) with a memory (10) for storing data relating to possible communication partners [(2)], a connecting device (11) for establishing communication connections with a communication partner (2) by way of different means of communication and a control unit (9) for triggering the connecting device (11) in order to establish a communication connection utilizing the data that is stored in the memory (10) and/or that can be entered manually.

Abstract: The present invention relates to a fan module (10) that is comprised of a stationary fan element (1) and of a movable fan element (2) that has the ability to rotate. The fan module (10) has contact surfaces (5) on an outside lateral surface (4) that can be used to supply an operating voltage to an electric motor of the fan module (10). Consequently, a fan module (10) according to the invention can be quickly assembled and disassembled, allowing it to be replaced during continuing operation.

Abstract: The invention relates to a computer with a housing (1) that has outwardly protruding geometries (6), preventing any setting-up of the computer housing (1) in an undesirable position.

Abstract: In a massively parallel processing (MPP) system, bandwidth efficiency and message packet latency rates are improved by providing routing elements that detect, isolate and identify various routing errors. More specifically, system lock-up, caused by corrupted message packets, can be prevented by analyzing a given sequence of message packet codes and words as they are received by an input buffer associated with a routing element. By analyzing the sequence, it is possible to determine whether a tail code fails to arrive in the prescribed sequence. If a tail code has been received in a way that is inconsistent with an expected sequence, all of the message packet codes and words received at the buffer can be discarded until a valid message packet start code is received.

Abstract: The invention concerns a fastener for screwless fixing of components (1) in a mounting cage (3).

Abstract: A display device which displays image information in a form perceivable by a blind person. For this purpose, the display device has a plurality of areally arranged elements (1), which are individually actuatable, and an actuation device for actuation of the elements (1), whereby through the elements (1), electronic image information (7) fed into the evaluation device (16) is tangibly represented through the elements (1). The actuator elements may be arranged areally on a flexible substrate (13), which are individually actuatable, whereby through the actuator elements (11), vibrations and/or heat and/or electrical impulses can be generated.

The first circuit configuration (1) is the bus master of the first communication bus (2). Furthermore, a second circuit configuration (4) is connected with the first communication bus (2). By employing a wait signal (11), which is generated in the second circuit configuration (4) and transmitted to the first circuit configuration (1), it is possible to expand read and write access to the first communication bus (2) to any random number of clock cycles.

Abstract: An object program is produced in a data processing system by linking a plurality of program modules. Internal program modules, which have been produced by means of a high-level language translator, and external program modules, are provided with names from mutually exclusive name classes. A matching routine of a first type is produced for each of the internal program modules, and a matching routine of a second type is produced for each of the program modules that are called by the internal program modules. The matching routines bridge different linking declarations.
