Abstract: A T-type inductor-capacitor-inductor (LCL) resonant converter and its soft switching modulation method under a full power range. A full bridge inverter circuit is provided at a primary side of a T-type inductor-capacitor-inductor (LCL) resonant converter.

The soft switching modulation method for the T-type LCL resonant converter under a full power range is provided based on the T-type LCL resonant converter. The soft switching modulation method requires all switching transistors to operate at a duty cycle of 50% within one cycle. A high-frequency alternating voltage of the primary side has a symmetrical waveform, and a high-frequency alternating voltage of the secondary side has a square waveform.

Abstract: Radio frequency (RF) transmitters of a device (aggressor device) may unintentionally transmit a high-power output signal to antennas of a receiving device (victim device). In some RF systems, a victim device may have no or little protection between its antennas and transistors in an integrated circuit. Performance or lifetime of the transistors may be negatively impacted due to large voltage swings that may result from the high-power signal received from the aggressor device. To prevent or mitigate impact to performance or lifetime of the transistors due to the large voltage swings, protection circuitry including switches and a direct current (DC) power source (e.g., a charge pump) may be implemented at an input of a receiver of the victim device to shunt the power from sensitive circuit components of the victim device.

Abstract: The present application relates to performing a scale-down of the computing resources allocated to executing a software application. For example, the software application for implementing a web server may be packaged as a container image, and one or more instances of the container images may be executed as one or more tasks. The individual tasks may be allocated a set of computing resources such as CPU and memory, and the incoming requests sent to the web server may be distributed across the tasks. If the volume of incoming requests drops below a threshold level, one or more of the tasks may be placed in standby mode, and the amount of computing resources allocated to such tasks may be reduced. When the volume of incoming requests returns above the threshold level, the amount of computing resources allocated to such tasks can be scaled back up to the full amount.

Abstract: A method for producing an epoxyalkane includes the step of separating a stream containing an epoxyalkane and an extracting agent in a separation column having a column kettle reboiler. A part of a stream in the column kettle of the separation column enters an extracting agent purifier and is treated to obtain a gas phase light fraction that returns to the separation column and a liquid phase heavy fraction that is subjected to a post-treatment. The method can be used in the industrial production of an epoxyalkane.
