    Abstract: A system may include a switch, a gate driver, and a signal conditioner. The switch may couple to a load. The gate driver may generate one or more gating signals to control one or more operations of the switch. The signal conditioner may receive an input signal associated with the switch and generate a modification signal that may modify the one or more gating signals based on the input signal. The modified gating signal may be used to reduce an amplitude of a voltage transient received by the switch to below a voltage threshold.

    Abstract: A memory device may include sideband circuitry to provide additional functionality without interfering with normal operations of the memory device. The memory device may also include sideband pins to provide sideband information to an external device. The sideband information may include various digital or analog signals. In some cases, a sideband circuit of the memory device may use a data protocol for communicating the sideband information with the external device. Furthermore, systems and methods for receiving sideband information from multiple memory devices of a memory system are described to reduce latency and increase functionality of a memory system including such memory devices.

    Abstract: A load balancing method for two compressors. The two compressors are used in a refrigeration system and are driven coaxially by the same driving device. The method comprises the steps of obtaining parameters, determining balance, and controlling start/stop states. The parameters in the step of obtaining parameters are parameters related to the two compressors. The step of determining balance comprises determining, on the basis of the obtained parameters related to the two compressors, whether load is balanced between the two compressors. The step of controlling start/top states comprises controlling the start/stop states of the two compressors according to whether the load is balanced.
