  • Publication number: 20240077392
    Abstract: According to the present disclosure, a measuring method of liquid mixture purity includes steps as follows. A storage tank is provided, wherein the storage tank is configured for storing a liquid mixture including formic acid and water. A calculating unit is provided, wherein a plurality of formic acid purity values are saved in the calculating unit. A pressure-decreasing and heating step is performed by reducing a pressure of the storage tank and heating the storage tank. A measuring step is performed by measuring in the inner space of the storage tank to obtain a pressure value, and measuring the liquid mixture simultaneously to obtain a temperature value. A calculating step is performed by inputting the pressure value and the temperature value into the calculating unit, wherein the calculating unit outputs one of the formic acid purity values corresponding thereto.

  • Patent number: 11726536
    Abstract: A method for increasing power supply voltage in an information handling system in a normal mode with a first peak voltage comprises, in response to receiving a request for a higher peak voltage, an embedded controller (EC) receiving information associated with the application including a request for power at a higher peak voltage, a housekeeping IC communicating a signal to a PWM IC to increase voltage supplied to the information handling system to the higher peak voltage, the PWM IC converting from the PSU to the higher peak voltage and starting a timer with a defined time period. If no additional requests for operating at the higher peak voltage are received before the time period expires, the PWM IC communicates a signal that power will stop being supplied at the higher peak voltage, and the information handling system returns to operating in the normal mode at the first peak voltage.

  • Patent number: 11411509
    Abstract: Systems and methods are provided to implement power supply units (PSUs) that are capable of operating on input power having different types of input voltage waveforms, including, but not limited to, pure sinusoidal waveforms, non-pure sinusoidal waveforms, and non-sinusoidal waveforms. Such a PSU may operate to continue supplying DC output power to a system load as long as the PSU is powered by any one of a variety of such different input power types, while at the same time also effectively monitoring for presence of input power provided to the PSU and shutting down the PSU in event of absence or termination of the input power to the PSU. Such a PSU may also automatically identify and adapt to changes between different types of input power while at the same time continuing to supply DC output power to a system load in an uninterrupted manner for as long as some type of input power is being provided to the PSU.
