Abstract: A device for retaining a printed circuit board module in a mounting groove of a cold plate, the device comprising an elongated housing made of metal, which has a cross-section in the shape of a horizontal U. A pressure piece made of metal is mounted in the housing so as to be displaceable transversely relative to the rotational axis of the housing and comprises a flat clamping surface on the front side. A rotary cylinder can be rotatably mounted in the housing so as to be transversely displaceable relative to the rotational axis. During a rotation, eccentric guide elements can be used to effect a forward displacement of the rotary cylinder. The pressure piece follows the displacement of the rotary cylinder and slides outward. The waste heat of the printed circuit board module is transported via the housing and the pressure piece to the cold plate.

Abstract: The present invention pertains to a switchgear cabinet for accommodating electronic plug-in modules with an interior in which the heat-generating plug-in modules can be inserted one on top of another, a roof area arranged above the interior and a base arranged underneath the interior and that forms a base area. The switchgear cabinet furthermore comprises an air channel that is arranged to the side of the interior and connects the roof area to the base area. A closed cooling circuit within the switchgear cabinet serves for carrying off the heat generated by the plug-in modules. A fan arranged in the roof area takes in air from the interior and blows this air into the air channel. The heated air from the air channel flows around a heat exchanger arranged in the base in such a way that the air is cooled and the thereby produced cooling air is admitted into the interior from below and flows through this interior vertically upwards.

Abstract: A sub-rack (1) for plugging and unplugging electronic plug-in modules (3) includes a housing (2) which has a front cover plate (5). Each plug-in module includes a cooling device including a heat sink (19). A liquid distributor (12) is mounted on the cover plate and in flow connection with each of the heat sinks via a feed line (10) and a return line (11), and the liquid distributor is arranged on the outside of and in the front region (4) of the sub-rack.

Abstract: A method for locking and unlocking a functionality of a television data receiver, in which executing the functionality locking function involves interrupting the display of an active channel, displaying a substitute signal, storing a current configuration of the receiver in a memory and configuring the receiver to a transitional state. Executing the functionality unlocking function involves performing authorization and upon successful authorization, reading the configuration of the receiver from the memory and configuring the receiver in accordance with the read configuration. The configuration may further include settings of applications active upon activating a functionality locking function.

Abstract: In a broadcast network access-management system comprising at least one master decoding device provided with a smart card, and at least one slave decoding device linked to it, and a transmitter device which generates and transmits entitlement management messages intended for the linked master and slave decoding devices and other devices, the master decoding device (11) and at least one slave decoding device (12) linked together are located in a defined distance and operate when a distance between them does not exceed the defined distance dependant upon a cable length, a configuration, a number and quality of splitters and connections.

Abstract: In a system for storing and searching for tags in a data stream, a signal processing block (120) contains a tag analysis block (121) providing functionality of procedures of searching and storing tags within an audio/video data stream. The tag analysis block (121) is provided with a configuration table (122) for storing configuration data for various types of recordings, defining distances of searching and storing tags. In this system a user tag is inserted at a place of existing tag when an existing tag distance is shorter or equal to a predefined tag searching distance. Otherwise, when there is no existing tag within the predefined tag searching distance, the user tag is inserted at the predefined tag searching distance.

Abstract: A control cabinet with a frame having framing profiles and covered with side members and at least one door. The frame surrounds the inside of the control cabinet where electrical components are integrated. An air conditioning device which is placed on at least one vertical side of the frame rejects heat generated inside the control cabinet. This invention provides this type of cooling apparatus with additional equipment without the need for a large number of pieces. For this purpose, a separating member, parallel to the lateral side and placed at a distance therefrom, is attached to the framing profiles and forms with the side channel an air guiding channel. Moreover, the separating member comprises several passages for providing a physical connection between the air guiding channel and the inside of the control cabinet. Furthermore, air can be conveyed through the air guiding channel and through at least one passage by using at least one fan.

Abstract: A control cabinet having a cabinet body with opened sides which can be closed at least partially by one or more side walls. An air conditioning device which is placed near at least one side wall rejects heat generated inside the cabinet body or guides it towards the inside of the cabinet body. This invention simplifies the design of the air conditioning device. For this purpose, an intermediate wall which is parallel to the side wall and located at a distance therefrom, is placed in such a way that it is oriented towards the inside of the cabinet body. In addition, the air conditioning device is placed in the intermediate space surrounded by the side wall and the intermediate wall.
