摘要： The invention relates to a process for generating a voltage (uDK) proportional to a rotation speed with a resolver (2) from the outputs of which may be taken two travel or angle-dependent, amplitude modulated sine-wave voltages (S1, S2) electrically phase shifted by 90 DEG , the amplitude of which is modulatable in accordance with the position of the rotor or the angle of rotation ( alpha ). The invention also relates to a circuit for implementing the process. According to the invention, a sine-wave amplitude signal (RL1, RL2) dependent on the position of the rotor or the angle of rotation ( alpha ) is obtained from the two amplitude modulated sine-wave signals (S1, S2), these sine-wave amplitude signals (RL1, RL2) are transformed into an approximate sine-wave signal (RL1A, RL2A) which is linear in a range of +/- 45 DEG around the zero transition, this approximate sine-wave signal (RL1A, RL2A) is differentiated and finally inverted and an analogue voltage (uDK) proportional to the rotation speed is composed depending on a detected rotor position ( alpha ) from the two differentiated signals (R'L1A, R'L2A) and the two inverted differentiated signals (R &cir& NOt 'L1A, R &cir& NOt 'L2A). This provides an economical process for detecting low rotation speeds which are measured by means of a resolver (2).

摘要： In order to generate a position-coded signal in a position sensor at virtually any given time, two tracks are scanned by two sensors, each of which generates a pair of sinusoidal signals (cos alpha , sin alpha ; cos beta , sin beta ) or a similar periodic signal with a definite phase relation at any given time, the periods of the phases being in the ratio m/m-1. The desired relative distance is derived from the difference between the two phase relations.

摘要： The invention relates to a process for correcting a pre-controlled reference flux ( psi w) for a field-oriented control containing a reference voltage model (16) of a converter-powered multi-phase machine and a circuit for implementing the process. According to the invention, a comparison between a reference voltage (¦Uw¦) used as a setting for the converter (24) and a predetermined maximum converter output voltage (Uwmax) provides a voltage control difference (Ue) from which, by means of a flux correction controller (48), a flux control value ( psi x) is generated which reduces the pre-controlled reference flux ( psi w) until the reference voltage (¦Uw¦) for the converter is lower than or equal to the predetermined maximum converter output voltage (Uwmax). Thereby, the field-oriented regulation never leaves the field-oriented range.

摘要： A position-coded goniometer comprises a track made of a uniform, magnetically conductive material with a profiled surface, which extends around the axis of rotation, and a pair of sensors opposite the track, which inductively scan the distance to the moving profiled surface. By suitable geometry, the two sensors can be made to emit approximately sinusoidal signals with a phase difference of 90°, whose phase relation is a reversible, single-valued function of the angle of rotation. Compensating sensors, whose signals are added to those of the sensor signals, can compensate distortions due to radial and/or axial play of the axis of rotation.

摘要： The invention relates to a process for compensating a phase and amplitude cycle between a multi-phase set and actual value (iRw, iSw, iTw and iRx, iSx, iTx) whereby first the quantity set value (|iw|) or the quantity actual value (|ix|) and the angular set value ( epsilon w) or the angular actual value ( epsilon x) of the set or actual value vector (i or i ) is found and then by quantity and phase a quantity setting (|iwxy|) and an angular setting ( epsilon wxy) are generated from a quantity difference (|iw|) - |iw|) and an angular difference ( epsilon w - epsilon x) which by quantity and phase are added to the output values (|iw|, epsilon w) of the set value vector computer (26), whereby this quantity and phase sum (|iKw|, epsilon Kw) is converted into a multi-phase, compensated set value (iRKw, iSKw, iTKw). The invention also relates to a circuit for implementing the process. It is thus possible for the phase and amplitude cycle to be compensated between a multi-phase set and actual value (iRw, iSw, iTw and iRx, iSx, iTx) despite the fact that the phase and amplitude cycle of the transmission behaviour dependent on an interference quantity (Mz) depends on a control range.
摘要翻译：本发明涉及用于补偿多相组和实际值（iRw，iSw，iTw和iRx，iSx，iTx）之间的相位和振幅周期的过程，其中首先量数设定值（| iw |）或数量实际值找到值（| ix |）和角度设定值（epsilon w）或设定值或实际值向量（i 或i x）的角度实际值（εx），然后按数量和相位从数量差（| iw |） - | iw |）生成数量设定（| iwxy |）和角度设定（epsilon wxy））和通过量和相位相加的角度差（ε-ε-εx）与设定值向量计算机（26）的输出值（| iw |，epsilon w）相关联，由此将该量和相位和（| iKw |，epsilon Kw）转换为多相补偿设定值（iRKw， iSKw，iTKw）。本发明还涉及一种用于实现该过程的电路。因此，尽管传输行为的相位和幅度周期取决于相位和幅度周期，但是相位和幅度周期可以在多相位和实际值（iRw，iSw，iTw和iRx，iSx，iTx）之间进行补偿干扰量（Mz）取决于控制范围。

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).
