Abstract: A non-limiting example method of printing device startup based on computed pen age includes reading a pen manufacturing date encoded in a pen of a printing device. The method includes computing a pen age for the pen of the printing device based on the pen manufacturing date, and selecting a startup level based on the computed pen age.

Abstract: A fluid thermal processing device may include a substrate, a platform projecting from the substrate, a fluid heating element supported by the platform, a temperature sensing element, distinct from the fluid heating element, supported by the platform and an enclosure supported by and cooperating with the substrate to form a fluid chamber about the platform. The fluid chamber forms a volume of uniform thickness conforming to and about the platform.

Abstract: The present disclosure is drawn to microfluidic chips. The microfluidic chips can include an inflexible material having an elastic modulus of 0.1 gigapascals (GPa) to 450 GPa. A microfluidic channel can be formed within the inflexible material and can connect an inlet and an outlet. A working electrode can be associated with the microfluidic channel and can have a surface area of 1 μm2 to 60,000 μm2 within the microfluidic channel. A bubble support structure can also be formed within the microfluidic channel such that the working electrode is positioned to electrolytically generate a bubble that becomes associated with the bubble support structure.

Abstract: The present disclosure is drawn to microfluidic devices. A microfluidic device can include a substrate, a lid mounted to the substrate, and a microchip mounted to the substrate. The lid mounted to the substrate can form a discrete microfluidic chamber between structures including an interior surface of the lid and a portion of the substrate. The lid can include an inlet and a vent positioned relative to one another to facilitate loading of fluid to the discrete microfluidic chamber via capillary action. A portion of the microchip can be positioned within the discrete microfluidic chamber.

Abstract: An apparatus includes a die having a receiving area for a blood sample. A chamber is mounted on the die and fluidically coupled to the receiving area to process the blood sample. The chamber includes a set of electrodes that applies a voltage to the blood sample. A hematocrit level of the blood sample is determined based on a change in impedance across the set of electrodes after the voltage is applied.

Abstract: A microfluidic blood coagulation testing die includes a substrate, a slot defined in the substrate permitting entry of a blood sample, a chamber defined in the substrate that collects red blood cells from the blood sample, and a microfluidic path that provides a fluid connection from the slot to the chamber. The microfluidic path includes a channel, an inlet disposed at one end of the channel and an outlet disposed at the other end of the channel.

Abstract: Examples herein provide a method. The method includes applying an electrical potential difference over a blood sample in a testing cassette of a microfluidic device, the cassette including a microfluidic channel through which the blood sample flows. The method includes measuring, over a duration of time, an electrical signal passing through the blood sample as the blood sample flows from a first end and coagulates at a second end of the microfluidic channel to obtain a measurement function as a function of time. The method also includes correlating the measurement function to a characteristic of the blood sample.

Abstract: Examples herein provide a device. The device includes a testing cassette including: a microfluidic channel connecting an input port at a first end to at least one sensor area at a second end, the channel is to allow a blood sample to flow from the input port to the at least one sensor area; at least two electrodes; and a micro-fabricated integrated sensor, wherein when an electrical potential difference is applied over the blood sample, the sensor is to measure, over a duration of time, an electrical signal passing through the blood sample as the blood sample flows from the input port to the at least one sensor area and begin to coagulate, thereby obtaining a measurement function as a function of time. The device includes a processor to correlate the measurement function to a characteristic of the blood sample.
