    Abstract: Example implementations relate to a water sense chamber. For example, an appliance may include a water sense chamber having a sensor, the water sense chamber to house a standard water sample. The appliance may also include a processor coupled to the water sense chamber, where the processor is to obtain a liquid sample from fluid used in an operation of the appliance, measure a first property of the liquid sample using the sensor, generate a comparison of the first property and a second property of the standard water sample, and perform an action based on the comparison.

    IPC: B41J2/175

    Abstract: In one embodiment a print liquid supply apparatus is provided to supply liquid to a liquid needle of a receiving station comprising a liquid container including an at least partially collapsible liquid reservoir an interface structure at a side of the container, including a liquid channel that includes a reservoir connecting portion that fluidically connects to the reservoir and a needle receiving portion to allow the liquid to flow from the reservoir to the needle; a liquid interface of the liquid channel adjacent the needle receiving portion and at a distance from the reservoir connecting portion, a front wall and/or edge adjacent the liquid interface including a push area which is disposed between the liquid interface and the container; and at least one key pen base and key pen protruding from the base in a direction parallel and opposite to the needle insertion direction; and a contact pad array next to the needle receiving liquid channel portion. In another example a sub-assembly of such apparatus is provided.

    Abstract: In one example in accordance with the present disclosure, at least one print liquid supply interconnected is described. Each print liquid supply interconnect includes a housing movable relative to a printer and tethered via a feed hose to the printer. The housing includes at least one needle to be inserted in a print liquid supply to allow print liquid to move between the print liquid supply and an ejection device and two keyed slots disposed on either side of a first needle to gate insertion to a print liquid supply with protrusions that match the two keyed slots. The housing also includes a guide feature adjacent the first needle extending between a first keyed slot and the first needle and an electrical interface to establish a data transmission path between the print liquid supply and the ejection device, the electrical interface disposed between the first needle and a second keyed slot.

    Abstract: A metered volume microfluidic device can include fluid flow microfluidics. The fluid flow microfluidics can include an inflow channel, a metered volume chamber positioned to receive working fluid from the inflow channel, a metered volume outflow channel positioned to receive and direct a metered volume of the working fluid when discharged from the metered volume chamber, and a capillary check valve. The capillary check valve can allow excess working fluid to exit the metered volume chamber when filling the metered volume chamber via the inflow channel. The capillary check valve can also prevent excess working fluid that has passed there through from being reintroduced into the metered volume chamber when the working fluid is discharged into the metered volume outflow channel.
