Abstract: An integrated semiconductor memory has memory cells that are combined to form addressable normal units and to form at least one redundant unit for replacing one of the normal units. In addition, the semiconductor memory has an address bus to which an address can be applied, and a redundancy circuit that is connected to the address bus. The redundancy circuit is used to select the redundant unit. An input of a processing unit is connected to a connection of the address bus and also to a connection for a test signal, and the output of the processing unit is connected to an input of the redundancy circuit. The redundant unit can be tested before the repair information is programmed in the redundancy circuit. The circuit complexity required for this is comparatively low.

Abstract: An integrated circuit has a first control unit for controlling the threshold potential of the transistors of a first conductivity type. In addition, it has a second control unit for controlling the threshold potentials of the transistors of a second conductivity type. The required value input of the second control unit is supplied with a required value for the threshold potential of the transistors of the second conductivity type, which is proportional to the actual value of the threshold potential of the transistors of the first conductivity type. Due to the dependence of the second control unit on the control by the first control unit, improved switching characteristics of the integrated circuit are achieved.

The support is formed by a heat body, which is assigned to the chip-substrate connection and is heated with thermal radiation by the radiation source.

Abstract: A control system for controlling an object function includes a base station and a portable code transmitter. The base station is at the object and has a transceiver unit for transmitting an interrogation signal. The code transmitter emits a response signal with a code information item in response thereto. The base station checks an authorization of the code information item contained in the response signal. The base station and/or the code transmitter determines a time period between a transmission of a part of the interrogation signal and a reception of a part thereof obtained in reaction thereto, and compares the time period with a predefined reference time period. The base station enables the object-specific function only if the measured time period is shorter than the reference time period even if the code information item of the response signal is correct.

Abstract: A filter configuration for a demodulated QAM signal has a first channel for a cosine demodulated component of the QAM signal, a second channel for a sine demodulated component of the QAM signal, a filter circuit, which receives the two signal components and for each signal component has one transfer function that is composed of terms in phase with this signal component and terms phase-shifted from it by &pgr;/2 and/or −&pgr;/2. The circuit configuration also includes a cross branch for picking up signal portions from the respectively other channel that correspond to the phase-shifted terms of the transfer function. In a first state, the circuit configuration connects the input of the cross branch to the first channel and the output of the cross branch to the second channel, and in a second state connects the input of the cross branch to the second channel and the output of the cross branch to the first channel. A slope detector especially suitable for use with this filter configuration is also provided.

Abstract: When an external terminal is signed on to a communications system, a short message service link is set up between the external terminal and a teleworking computer connected to the communications system. Control information which is transferred from the external terminal via the short message service link is converted by the teleworking computer into signaling information that is usually available within the scope of a signaling protocol between internal terminals and the communications system. The converted short message control information is then transferred on to a control unit of the communications system.

Abstract: A drink container, such as a drinking glass, drinking cup, a vase, or a bottle, is illuminated with an LED. The power for the LED is supplied by quick-charging capacitors which are integrated in a cavity of the container together with the LED. The LED is disposed in a wedge-shaped recess which effects advantageous distribution of the light through the obliquely inclined walls. The capacitors are typically charged within a matter of seconds and they have a virtually unlimited cycle life.

Abstract: A method for measuring characteristics of radio channels, in which the signals are received by a total of M1 receiving sensors in a linear antenna array, in which case the respective received signals are composed of wave elements of a transmitted signal with a different incidence direction and different delay, the transmitted signal contains a preselected test sequence, and the incidence angle as well as the delay of the dominant wave fronts are estimated simultaneously, taking account of the chip signal form of the test sequence, the signals from each antenna sensor are demodulated, and sampling is then carried out with Mc samples per chip in the test sequence.
