摘要： This invention concerns a process for optimizing the power-down cycle of a non-engaging, interruptable power semiconductor switch (2) in a saturating power converter and a device for carrying out the process. According to the invention, when the interrupt signal (Saus) arrives, the gate emitter voltage (UGE) of this power-semiconductor switch (2) lowered with the help of a maximally permissible discharge current and its collector-emitter voltage (UCE) are monitored against exceeding a reference voltage (UCEref), the value of which is set so that the collector current (IC) begins to commutate, and upon reaching the reference value (UCEref), the discharge current is reduced to a value which is below the value of the maximum permissible discharge current. Thus, the power-down cycle of a non-engaging, interruptable power semiconductor switch (2) is largely optimized, so that the voltage rise and current drop times can be separately controlled.

摘要： The invention pertains to a low-loss power current inverter. According to the invention, each current inverter phase (2) comprises an upper and a lower bridge half (6, 8) each of which contains two power semiconductor switches (T1, T2 and T3, T4) with back-to-back diodes (D1, D2 and D3, D4). One connection point (10, 12) of each power semiconductor switch pair (T1, T2, and T3, T4) is connected by a decoupling diode (D5, D6) to a connection point (M) of a direct voltage intermediate circuit (4). An auxiliary circuit (14) comprising an upper and a lower auxiliary switch (16, 18) and a resonance inductance (LR) is provided, as well as at least one resonance capacitor (CR) for the power semiconductor switches (T1...

摘要： The invention concerns a device for reducing the short-circuit amplitude of a disconnectable, non-latching MOS-controlled power semiconductor (TL1) with a control unit presenting a driver stage (10) with two complementary transistors (T2, T3), a collector-emitter control (8) and a limiting circuit (6), that is placed between an input (12) and a reference potential ("-") of the driver stage (10). Said limiting circuit (6) is connected to an output (16) of the collector-emitter control (8) on the input side, which is interconnected with the collector connection (C) of the power semiconductor (TL1) on the input side by means of a decoupling diode (D1). The decoupling diode (D1) is connected by a resistance (R1) on the anode side with a positive terminal of a first control voltage source (UH1) of the driver stage. The invention foresees an additional transistor (T5) and a resistance (R5) . Said additional transistor (R5) and its collector-emitter section are connected electrically parallel to the base-emitter section of the switching transistor (T2) of the driver stage (10) and the resistance (R5) between the base and the emitter of said additional transistor (5). The control circuit resistance (RG) is bypassed by a diode. Thus, the known device for reducing a short-circuit amplitude of a disconnectable, non-latching, MOS-controlled power semiconductor (TL1) is improved in such a way, that its switching speed no longer changes.

摘要： The embodiments relate to a near field communication system including a plurality of near field communication devices which communicate with each other via a radio interface. During generation of a common cryptographic key between the near field communication devices of the near field communication system, at least one of the two near field communication devices monitors during generation of the cryptographic key via the radio interface in a generation period whether an additional near field communication device which could be a potential active attacker communicates with one of the near field communication devices via the radio interface. If such a suspicious type of communication is detected, generation of the common cryptographic key is optionally terminated.

摘要： A cordless telephone has several mobile elements (MTn) allocated to a fixed element (FT). In order to establish a connection between the fixed element (FT) and one of the mobile elements (MTn), an incoming call (AR) is converted to an outgoing call. The exchange of the required communication data occurs exclusively over speech channels. An identification code with group or individual identification is emitted by the fixed element (FT) as an identification message (KMn) with a call message (RM). The call is signalled by the mobile parts (MTn) connected to one group. Call-indicator messages (RAM) are sent back one by one on a free channel. The fixed element (FT) monitors the channels until an established-connection message (VAM) is sent by a mobile element (MTn), a fork switch having been actuated. Said mobile part (MTn) thereby initiates the establishment of a connection. The fixed part (FT) can also call one mobile part (MTn) after another individually. Each mobile part (MTn) sends back on the same channel the call-indicator message (RAM) and, after the fork switch has been actuated, the established-connection message (VAM).
摘要翻译：无绳电话具有分配给固定元件（FT）的几个移动元件（MTn）。为了在固定元件（FT）和移动元件（MTn）之一之间建立连接，来电（AR）被转换为去话呼叫。所需通信数据的交换仅在语音信道上发生。具有组或个人标识的识别码由固定元件（FT）作为具有呼叫消息（RM）的标识消息（KMn）发出。呼叫由连接到一个组的移动部分（MTn）发出信号。呼叫指示符消息（RAM）在空闲频道上逐个发送回来。固定元件（FT）监视通道，直到建立的连接消息（VAM）由移动元件（MTn）发送，叉开关已被致动。所述移动部分（MTn）由此启动建立连接。固定部分（FT）也可以单独调用一个移动部分（MTn）。每个移动部分（MTn）在相同的信道上发回呼叫指示符消息（RAM），并且在叉交换机被激活之后，建立连接消息（VAM）。

摘要： In a receiver for digitally modulated signals in mobile communication systems, the reception signal can be represented as a complex vector. The signal undergoes homodyne or heterodyne incoherent conversion in a mixing stage with mixers (M) in which it is decomposed into a real component and an imaginary component. The signal components are filtered by low-pass filters (TP) and digitized by analog/digital converters (AD). The scanned values are converted into the magnitude and direction of the vector. The magnitude (B) controls the amplification of the preliminary amplifier (VV) and of the low-pass filters (TP), and the reception data are derived from the difference between two consecutive values of the direction (W).

摘要： An antenna for the transmitter and receiver of a portable radio appliance (cordless telephone, mobile telephone, pager, telepoint appliance, etc.) consists essentially of two sheet metal angles (2, 3) arranged side by side. One of the two elements is excited with high-frequency currents by means of a coaxial supply line (4). The second sheet metal angle (3) is excited through radiation coupling by the first sheet metal angle (2). The sheet metal angles (2, 3) are aligned in the same direction and the distance between them in the end region is considerably less than in the bent edge of the apex line. This results in high cross-currents and low impedance. The antenna can also be modified by supplying both sheet metal angles (2, 3), subdivision into two identical partial antennae or several sheet metal angles. The sheet metal angles can consist of metal foils placed on a plastic housing. An embodiment with wire angles is also possible.
