  • Publication number: 20220310155
    Abstract: The present invention provides an output driving circuit and a memory device. The output driving circuit is provided with a pull-up pre-amplification unit and a pull-down pre-amplification unit between a signal input terminal and a signal output terminal, the pull-up pre-amplification unit and the pull-down pre-amplification unit adjust the duty cycle ratios of the positive input signal and the negative input signal so that the duty cycle ratios of the output signals at the signal output terminal is the same as that of the input signal at the signal input terminal, which avoids the mismatch of output impedance under different output voltages, thereby eliminating the problem of duty cycle ratio deviation of the output signal that affects the signal quality.

  • Publication number: 20220290079
    Abstract: The present disclosure discloses a Pichia kudriavzevii and a multifunctional complex microbial inoculant and use thereof, and belongs to the technical field of bioengineering. The Pichia kudriavzevii of the present disclosure has a degrading ability of lactic acid as high as 12.69 g·L?1, which is 2.04 times that of a type strain. At the same time, the strain can also metabolize ethanol and has an OD600 of 4.48 after fermentation in a sorghum juice medium at 30° C. and 200 rpm for 3 d. The Pichia kudriavzevii could completely consume 58 g·L?1 of glucose in the sorghum juice medium after 60 h of fermentation and produce 13.06 g·L?1 of ethanol. The Pichia kudriavzevii degrades lactic acid and can relieve a lactic acid pressure of a fermentation system and enable Saccharomyces cerevisiae to grow and metabolize to produce wine.

  • Patent number: 11399064
    Abstract: In one embodiment, a method for managing data includes collecting workload information for a data storage device in a data storage system over a period of time. A peak workload of the data storage device for the period of time is determined. A maximum workload threshold for the data storage device in the data storage system over the period of time is also determined. Movement of additional workload to the device in the data storage system is prevented during a subsequent period of time when the data storage device is predicted to be at about the peak workload for the data storage device in response to a determination that adding the additional workload would cause the workload of the device to exceed the maximum workload threshold.

  • Publication number: 20220221934
    Abstract: A wearable device may include a head-mounted display (HMD) for rendering a three-dimensional (3D) virtual object which appears to be located in an ambient environment of a user of the display. The relative positions of the HMD and one or more eyes of the user may not be in desired positions to receive, or register, image information outputted by the HMD. For example, the HMD-to-eye alignment vary for different users and may change over time (e.g., as a given user moves around or as the HMD slips or otherwise becomes displaced). The wearable device may determine a relative position or alignment between the HMD and the user's eyes. Based on the relative positions, the wearable device may determine if it is properly fitted to the user, may provide feedback on the quality of the fit to the user, and may take actions to reduce or minimize effects of any misalignment.

  • Patent number: 11379036
    Abstract: Systems and methods for eye tracking calibration in a wearable system are described. The wearable system can present three-dimensional (3D) virtual content and allow a user to interact with the 3D virtual content using eye gaze. During an eye tracking calibration, the wearable system can validate that a user is indeed looking at a calibration target while the eye tracking data is acquired. The validation may be performed based on data associated with the user's head pose and vestibulo-ocular reflex.
