    摘要： A method for synchronization and transmission of information in a distributed measurement and control system, wherein frames, being a sequence of bits, are transmitted between a master node (M) and a slave node (S), the method comprising cyclically performing the steps of: receiving (101) at the master node (M) an echo frame sent from the slave node (S) as an echo of the last frame received by the slave node (S) from the master node (M); determining (102) the time of frame propagation between sending the frame from the master node (M) and receiving the echo frame at the master node (M); constructing (103) a subsequent frame at the master node (M), the subsequent frame comprising a data field comprising a time adjustment dependent on the determined time of frame propagation; sending (104) the subsequent frame from the master node (M) to the slave node (S); receiving (105) the subsequent frame at the slave node (S); and adjusting (106) a timer (S_T) of the slave node (S) depending on the value of the time adjustment read from the received subsequent frame and sending the received frame to the master node (M) as an echo frame.

    摘要： Method for encoding analog signal into time intervals consists in a generation of time intervals using a time encoding machine (TEM). A signal of a constant value is held during a generated time interval on a time encoding machine (TEM) input by the use of a sample-and-hold circuit SH, while the constant value of the signal held during the generated time interval represents an instantaneous value of the analog signal at the end of a generation of a previous time interval.

The signal is provided to an input (SHin) of the sample-and-hold circuit (SH), whose output (SHout) is connected to an output (TEMin) of the time encoding machine (TEM). The output (TEMout) of the time encoding machine (TEM) is connected to an output (Out) of the apparatus, and to a control input (SHctr) of the sample-and-hold circuit (SH).

    摘要： A method for controlling a resonant-mode power supply, the resonant-mode power supply comprising an assembly of switches (K1, K2, K3, K4), between which a resonant circuit with an output load is connected, and a controller (C) configured to stabilize output voltages or currents by controlling switching frequency of the assembly of switches (K1, K2, K3, K4) in response to the output of a slow-response monitoring circuit (SMC) configured to monitor the output voltage or current and having a certain time (τ1) of response to changes of value of the output voltage or current. The power supply further comprises an energy recirculation circuit (ERC1) in which the current (Ilim) is monitored by means of a fast-response monitoring circuit (CMC1) having a time (τ2) of response to changes in the (Ilim) current faster than the response time (τ1) of the slow-response monitoring circuit (SMC). The method involves adjusting, via the controller (C), the switching frequency of the assembly of switches (K1, K2, K3, K4) such as to reduce the power supplied to the resonant circuit upon exceeding a threshold value by the current (Ilim).
