摘要:
A subsea production system for producing fluids from a subsea well in a subsea field. The production system includes a production facility and a production umbilical connecting the subsea well with the production facility. The production system also includes a control system for controlling production from the subsea well. The control system includes a first redundant master control station system (redundant MCS) at a first location, the redundant MCS capable of controlling production from the subsea well. The control system also includes a second redundant MCS at a second location, the second redundant MCS capable of controlling production from the subsea well. The redundant MCSs are synchronized to keep the same electronic data at both locations and to prevent conflicts in control signals from the redundant MCSs.

A status latch with one-phase control signal is constructed only from purely static gates, thus has great security against interference in the stationary state, and is thus suited in particular for low-voltage operation. In the one-phase latch, the power loss is particularly low due to the lower wiring capacity of the control lines, for which reason it can be advantageously used in particular in digital circuits with high data rates. Advantageously, a low number of transistors is required.

Data transmission through data paths is synchronized using a symmetrical clock signal. In order to avoid dynamic hazards, which arise due to different delay times during data transmission in the data paths, an intermediate storage element is respectively arranged in each data path. It does not forward the received data signals into the subsequent circuit blocks until towards the end of the clock signal impulse used for the synchronization of the data transmission.
摘要:
A circuit for measuring distances and which has at least two inputs (1, 2), at least one measuring coil (3), and at least one signal source, wherein at least two input signals (epos, eneg) are generated by means of the signal source, and the inputs (1, 2) are activatable by means of the input signals (epos, eneg). The input signals (epos, eneg) are applied, preferably preprocessed, to the inputs of the measuring coil (3). The circuit is designed for use where little space is available for the circuit, with the input signals (epos, eneg) being applied to a preferably timed SC network, which generates a measuring output signal that is dependent on temperature. A corresponding method is also described.

A circuit and method for demodulating at least one modulated signal (e), such as a measuring signal of a sensor. The circuit comprises at least one input (1), with the signal (e) being applied to the input (1), and the input is connected to at least one switched-capacitor network which is configured to demodulate the signal. The circuit permits use even in a small available space.

In a modified Booth's algorithm only one shift unit is required for multiplication of the partial products. This is based on the known coding prescriptions of the Booth's algorithm, which respectively determines from 3 bits of the multiplier how the partial products are to be produced. From the respective 3 bits of the multiplier of the current iteration and of the preceding iteration, it is determined whether the partial product used for the next iteration has to be multiplied by 1/2, 1/4 or 1/8. For this purpose, a coding table and a multiplier that operates according to this principle are provided.

The operational amplifier which has a high input impedance as well as a high bandwidth, is designed particularly for capacitive loads and, above all, maintains its operating point within narrow limits irrespective of technological fluctuations. The BiCMOS amplifier uses bipolar cascades (Q6, Q16, Q7, Q17) as output paths which are driven at high impedance, via PMOS cascade transistors (M6, M7), directly by the differential amplifier transistor pair (M4, M5), as a result of which a current is output and the maintenance of the operating point of the operational amplifier is ensured even when technological fluctuations are taken into account.
