Abstract: According to an example, a microfluidic apparatus may include a fluid slot, a foyer in fluid communication with the fluid slot via a channel having a relatively smaller width than the foyer, a sensor to detect a presence of a particle of interest in a fluid passing through the channel, a nozzle in fluid communication with the foyer, and an actuator positioned in line with the nozzle. The microfluidic apparatus may also include a controller to receive information from the sensor, determine, from the received information, whether a particle of interest has passed through the channel, and control the actuator to expel fluid in the foyer through the nozzle based upon the determination.

Abstract: An example printhead assembly includes a housing, nozzles and a collapsible container within the housing to supply ink to the nozzles. The collapsible container includes a top wall, a bottom wall, first and second side walls that form an interior and a spring assembly within the interior. The first flexible wall includes a first amount of excess material. The second flexible wall includes a second amount of excess material less than the first amount of excess material such that motion of the first flexible wall of the collapsible container is constrained against movement to a lesser extent as compared to the second flexible wall. The first flexible wall faces the sensor. A sensor assembly is coupled to the housing and includes a sensor to provide a sensor signal indicating the amount of ink within the collapsible container.

Abstract: A liquid dispenser cassette includes a frame, dispense head assemblies, and a one-piece integrated slot extender. The frame defines openings. The dispense head assemblies are mounted on the frame. The dispense head assemblies include dispense head dies at least partially exposed through the corresponding openings. The dispense head dies defines top slots. The slot extender is mounted on the dispense head assemblies. The slot extender has reservoirs defining drain openings mated to the corresponding top slots.
Abstract translation: 液体分配器盒包括框架，分配头组件和单件集成插槽延伸器。 框架定义开口。 分配头组件安装在框架上。 分配头组件包括至少部分地通过相应的开口露出的分配头模具。 分配头模具定义顶部槽。 插槽延伸器安装在分配头组件上。 狭缝延伸器具有限定排出开口的储存器，排出口与相应的顶部狭槽配合。

Abstract: According to an example, a microfluidic apparatus may include a channel, a foyer, in which the foyer is in fluid communication with the channel and in which the channel has a smaller width than the foyer, a sensor to sense a property of a fluid passing through the channel, a nozzle in fluid communication with the foyer, and an actuator positioned in line with the nozzle. The microfluidic apparatus may also include a controller to determine whether the sensed property of the fluid meets a predetermined condition and to perform a predefined action in response to the sensed property of the fluid meeting the predetermined condition.

Abstract: One example of a printhead assembly includes a housing including sidewalls, nozzles to eject ink drops, a collapsible container, and a sensor assembly. The collapsible container is within the housing to supply ink to the nozzles. The collapsible container includes flexible sidewalls and a spring assembly between the flexible sidewalls. The sensor assembly is coupled to the housing and includes a sensor to provide a sensor signal indicating the amount of ink within the collapsible container.
