Abstract: In one example, a processor readable medium having instructions thereon that when executed cause an additive manufacturing machine to vary operating characteristics of a fusing laser beam at multiple different voxel locations in a layer of build material according to an energy dosage to be applied at each voxel location in an object slice, including multiple different energy dosages for corresponding multiple different voxel locations in the slice.

Abstract: In one example, a fluid flow structure includes a fluid dispensing micro device embedded in a molding having a channel therein through which fluid may flow directly to the device. The device contains multiple fluid ejectors and multiple fluid chambers each near an ejector. Each chamber has an inlet through which fluid from the channel may enter the chamber and an outlet through which fluid may be ejected from the chamber. A perimeter of the channel surrounds the inlets but is otherwise unconstrained in size by the size of the device.

Abstract: Example embodiments relate to processing a scanned form by causing an action to occur. The scanned form includes a unique identifier that indicates that the action is to occur when the form is scanned. The unique identifier is detected in the scanned form data. The scanned form data may be transmitted to a server to use the unique identifier to identify the action to execute for processing the scanned data.

Abstract: A method of detecting passage of a particle into a target location includes receiving a sample on a die including a microfluidic chamber, the microfluidic chamber including a microfluidic path coupling a reservoir to a foyer, and moving the sample from the reservoir to the foyer by firing a nozzle fluidically coupled to the foyer. The method further includes detecting passage of a particle of the sample from the reservoir to the foyer via a first sensor disposed within the microfluidic path, and detecting passage of the particle into the target location via a second sensor disposed between the first sensor and the nozzle. The method includes recording in a dispense map, an indication of whether the target location includes a single particle or multiple particles based on signals measured by the first sensor and the second sensor.

Abstract: Aspects of the present disclosure relate to evaporation compensation in fluidic devices. An example apparatus for evaporation compensation includes an assessment circuit to determine an amount of evaporation of a volume dispensed in a microwell of a fluidic device. The amount of evaporation may be determined based on the volume in the microwell, and an amount of time after dispensing the volume in the microwell. A compensation circuit may determine, based on the amount of evaporation, a compensation factor for the microwell including an amount of a normalizing fluid to compensate for the amount of evaporation. The compensation circuit may also create a normalization profile for the fluidic device, including an association between the fluidic device and the compensation factor. A dispensing circuit may dispense the normalizing fluid in the microwell according to the normalization profile.

Abstract: In one example in accordance with the present disclosure, a chemical lysis system is described. The chemical lysis system includes a microfluidic channel to serially feed individual cells from a volume of cells to at least one chemical lysing device. Each chemical lysing device includes at least one lysing chamber to receive, from the microfluidic channel, a single cell to be lysed. The chemical lysing device also includes an orifice disposed in each lysing chamber to receive a lysing agent and a sensor to detect a state within the lysing chamber. A controller of the chemical lysis system analyzes a ruptured cell.

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: An apparatus includes a media that includes an encoded pattern to indicate a location of each of a plurality of dispensing locations on a receiving area for a pipette dispenser. The encoded pattern is employed to guide the pipette dispenser to dispense a volume to a selected dispensing location from the plurality of dispensing locations based on a predetermined dispensing location on the receiving area.

Abstract: A reagent deposition area of a reagent dispensing system may include a dispersion bar located above a conveyor system, and a reagent module coupled to the dispersion bar. The reagent module may include at least one reagent dispensing device to dispense a number of reagents on a substrate carried on the conveyor system, and a module frame electrically and mechanically coupling the reagent dispensing device to the reagent dispensing system. The dispersion bar moves the reagent module in two coordinate directions planar with the surface of the substrate.
