  • Patent number: 12325009
    Abstract: The present application discloses an impeller assembly and a mixing apparatus, and relates to the technical field of solid and liquid mixing devices. The impeller assembly includes an impeller structure and a housing structure. The impeller structure includes a body, and a surface of the body is provided with a plurality of backward-skewed blades. A blade angle of each backward-skewed blade on any flow plane first decreases progressively and then increases progressively from an inlet to an outlet. A first baffle is disposed on a lower portion of the body. The housing structure includes a second baffle. The first baffle is provided with first guide slots, and the second baffle is provided with second guide slots. A fluid enters from the inlet at an upper portion of the body, flows along the surface of the body, and flows out through the outlet at a lower portion of the body and through the first guide slots and the second guide slots.

  • Patent number: 11366934
    Abstract: A method for providing an anti-rollback secure timer service includes determining, at a device which includes a processor providing a trusted execution environment (TEE), a trusted memory, and a real time clock (RTC) accessible through an operating system of the device, an initial reference time value, by a secure timer application running in the TEE, the initial reference time value determined based on an initial value of the RTC obtained during booting of the device and a time delta value. The method further includes determining an updated reference time value based on the initial reference time value, a second value of the RTC, and a previously stored old reference time value, determining an updated time delta value based on the second value of the RTC and the updated reference time value, and storing the updated time delta value and the updated reference time value in the trusted memory.
