  • Publication number: 20200164371
    Abstract: A sample test device is provided that includes a body having an insertion surface spaced apart from a distal end portion and a fluid manipulating assembly disposed in the distal end portion. A mixing receptacle is defined in the fluid manipulating assembly and provides a volume to mix a test mixture. A plunger is disposed in the body and creates a positive air pressure in the mixing receptacle when inserted into the body. A test die is disposed in the fluid manipulation assembly and a fluid path extends from the mixing receptacle to the test die. Activation of the plunger creates a positive pressure in the mixing receptacle to force the test mixture to flow from the mixing receptacle to the test die.

  • Patent number: 10664402
    Abstract: Example implementations relate to read operation redirect. For example, a system according in the present disclosure may include a data storage device accessible by a host. The system may include an input/output filter of an operating system of the host. The input/output filter may monitor read operations and write operations from the host to the data storage device. The input/output filter may copy a portion of the data storage device to a random-access memory (RAM) buffer within the host responsive to monitored read operations to the portion exceeding a threshold. The input/output filter may redirect a successive read operation, addressed to the portion of the data storage device, to the copy of the portion in the RAM buffer.

  • Patent number: 10661503
    Abstract: In a three-dimensional (3D) printing method example, build material granules are applied. Each of the build material granules includes a plurality of primary ceramic particles agglomerated together by a binder that is at least partially soluble in a primary solvent of a fusing agent. Pressure is applied to crush the build material granules. The fusing agent is selectively applied on at least a portion of the build material granules or the crushed build material granules to pattern the portion, and to introduce a latent binder to the portion. The application of the build material granules, the application of the pressure, and the selectively application of the fusing agent are repeated to create a green body. The latent binder is activated by heating the green body in order to produce a cured green body.
