Electrical or electronic apparatus

Abstract: The invention concerns an electrical or electronic apparatus (1) to be placed on a carrier rail (2), with a housing (3), at least one printed circuit board (4) disposed in the latter, and contacts (6a, 6b) pointing in the carrier rail longitudinal direction (R) for a data- and/or energy-bus connection to adjacent electrical or electronic apparatus which are placed on the carrier rail (2) and comprise corresponding contacts. According to the invention, in order to be able to replace the printed circuit board (4) in a simple manner, without interrupting the data- and/or energy-bus connection, the housing (3) is designed in at least two parts, an upper part (7) receiving the printed circuit board (4) and a base part (8) comprising the contacts (6a, 6b) being provided.

Building cognitive radios in MATLAB Simulink — A step towards future wireless technology

Abstract: Cognitive Radio (CR) is a future radio technology that is aware of its environment, internal state and can change its operating behavior (transmitter parameters) accordingly. It is intended to coexist with primary users (PUs) for using the underutilized spectrum without any harmful interference. Its key domains are sensing, cognition and adaptation. This paper presents a detailed survey of coexistence techniques used in IEEE 802 wireless network standards family to reduce the interference between different types of networks. It also presents a prototype system for designing and testing cognitive radios built on top of software defined radio in a MATLAB/-Simulink and interfaced with a universal software radio peripheral-2 (USRP2) main-board and RFX2400 daughter board from Ettus Research LLC. The philosophy behind the prototype is to sense, predict and adjust the operating parameters to achieve the desired objectives. The PUs detection (sensing) is performed using the statistical (non-parametric) spectrum estimation techniques, which are more useful in a noisy environment. Regression-based statistical time-series modeling & analysis are carried for PU's channel behavior prediction for spectrum decisions. Software-defined radio is used for reconfigurability to adjust the operating parameters of the cognitive radios.

Cooling element for heat dissipation in electronic components

Abstract: A cooling element for heat dissipation in one or more electronic components includes a metal element with one or more slit-shaped receiving openings for one or more electronic components that are to be cooled. In its lengthwise extension, each receiving opening has a receiving bore that holds a helical spring and that runs parallel to the lengthwise extension. The receiving bore is arranged in such a way that it is open on the lengthwise side towards the receiving opening and the spring placed in it projects with a radial partial section into the receiving opening that holds the electronic component. As a result, in partial areas, the spring presses the electronic component against the inner wall of the receiving opening that lies opposite from the spring, thus establishing thermal contact.

Pluggable conductor terminal

Abstract: A pluggable conductor terminal includes a plug connector ( 6 ) with a pin guide ( 8 ) emptying into a contact space ( 5 ) and a conductor guide channel ( 24 ) with a conductor connection aperture ( 25 ) that is transformed into a central clamping space ( 19 ) in the clamp housing The conductor guide channel ( 24 ) is inclined toward the pin guide ( 8 ) A contact piece ( 3 ) with a contact part ( 4 ) for the contact pin ( 7 ) is mounted in the contact space ( 5 ) with a clamp spring ( 15 ) for the conductor ( 33 ) in the clamping space ( 19 ) For the sake of simpler manufacture, the contact piece ( 3 ) and the clamp spring ( 15 ) are of one piece, and consist of an elongated, flat band ( 2 ) bent exclusively crosswise to its longitudinal dimension

PROFINET ethernet adapter

Abstract: The present invention relates to a PROFINET adapter having at least one first Ethernet interface (511) and one second Ethernet interface (512) for coupling a subscriber to a PROFINET network. The PROFINET adapter (50) comprises a third Ethernet interface (55), a number of at least one application interface (53, 54) and a separating filter (56). The third Ethernet interface (55) is designed at least to interchange Ethernet-based data packets. The separating filter (56) is connected to the switch (51), the PROFINET protocol stack (52), the application interfaces (53, 54) and the third Ethernet interface (55) and is designed to divide real-time data packets and non-real-time data packets according to a particular configuration and to transmit said data packets between the switch and the application interface and/or the third Ethernet interface.
