  • Publication number: 20240059069
    Abstract: According to an example, a method to determine a printing fluid pressure in a printing fluid delivery system comprises: determining that a pressure difference measured by a fluid pressure sensor of the printing fluid delivery system is outside a dynamic range of the pressure sensor, controlling a fluid supply system of the printing fluid delivery system to increase a fluid pressure to an augmented fluid pressure in which the pressure difference is within the dynamic range of the pressure sensor, determining a fluid pressure value on the fluid pressure sensor, and calculating the printing fluid pressure as a function of the pressure difference and the augmented fluid pressure.

  • Publication number: 20240061884
    Abstract: A self-adaptive data filter is developed to process data having tree-structured formats, such as, JSON, XML, and YML. Unlike conventional data filtering methods, which require different filters for different data structures, in one aspect, the disclosed self-adaptive data filter is data structure agnostic and can be used to process a wide variety of data structures. In another aspect, the self-adaptive data filter of this disclosure allows for fuzzy search.

  • Patent number: 11907733
    Abstract: An example target device is described for facilitating application docking. In various aspects, the target device can comprise a processor. In various instances, the target device can comprise a non-transitory machine-readable memory that can store machine-readable instructions. In various cases, the processor can execute the machine-readable instructions, which can cause the processor to launch, based on a dock request that is to indicate a session of a first instance of an application of an initiator device, a second instance of the application on the target device. In various aspects, the second instance can resume the session. In various instances, the launch can be based on a determination that a dock credential of a Quick Response (QR) code generated by the target device is in the dock request.
