Abstract: Examples include a fluidic device comprising a fluidic die, a support element, and a conductive member. The support element is coupled to the fluidic die, and the support element has a fluid channel formed therein. The fluid channel exposes at least a portion of aback surface of the fluidic die. The support element further includes a member opening passing therethrough. The conductive member is connected to the fluidic die, and the conductive member is a least partially disposed in the member opening such that a portion of the conductive member is exposed to the fluid channel of the support element.

Abstract: A sensor circuitry package for a replaceable print apparatus component including a plurality of sensing zones, each sensing zone including a number of sensing devices, each sensing device having a respective sensing function, and an array of memory elements, each memory element corresponding to a respective one of the sensing zones. During a sensing operation, the array of memory elements to serially load a segment of select bits, each select bit having one of a select value and a non-select value, a memory element having a select value to select a number of sensing devices of the respective sensing zone to be enabled to perform its respective sensing function.

Abstract: Examples include microfluidic devices. Example microfluidic devices comprise a microfluidic channel, a capillary chamber, and a fluidic actuator. The microfluidic channel is fluidly connected to the capillary chamber. The capillary chamber is to restrict flow of fluid therethrough. The fluidic actuator is positioned proximate the capillary chamber. The fluidic actuator is to actuate to thereby initiate flow of fluid through the capillary chamber.

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.
