    Abstract: A plunger head for a medication injection device includes a first ultrasonic transducer coupled to emit ultrasonic signals, where the first ultrasonic transducer is oriented within the plunger head to send the ultrasonic signals along a length of a barrel of the medication injection device when the plunger head is disposed in the barrel. A second ultrasonic transducer is disposed within the plunger head and oriented to receive reflections of the ultrasonic signals. A controller is disposed in the plunger head and coupled to the first ultrasonic transducer and the second ultrasonic transducer. The controller includes logic that when executed by the controller causes the controller to perform operations including instructing the first ultrasonic transducer to emit the ultrasonic signals.

    Abstract: An apparatus for tracking an amount of dispensed fluid, a system for fluid injection including the apparatus, and related methods of use are described. In an embodiment, the apparatus includes a dosage meter shaped to couple with a leadscrew and a cartridge containing a fluid for injection, and configured to track fluid injection. In an embodiment, the dosage meter includes an index wheel including a plurality of teeth, wherein the index wheel is shaped to position coaxially with a major axis of the leadscrew and to receive rotational motion from the leadscrew; and a cantilevered protrusion positioned to deflect due to contact with the plurality of teeth as the index wheel rotates coaxially with the leadscrew inducing a strain in the cantilevered protrusion, wherein the dosage meter outputs a signal indicative of the strain.

    Abstract: An insect separating apparatus may include a sensor positioned to detect one or more insects when present within a test chamber. For example, the sensor may emit signals into the test chamber and receive reflected signals indicative of Doppler shifts caused by movement of the one or more insects. Based on information from the sensor, a computing device may determine a characteristic of the one or more insects in the chamber, such as a wing beat frequency, sex, or other characteristic. The computing device may instruct different responses based on the characteristic determined, such as activating an air mover to divert detected mosquitoes out of the test chamber in response to the determined characteristics matching those of female mosquitoes, or deactivating or maintaining the air mover in an inactive condition in response to the determined characteristics matching those of male mosquitoes, for example, to allow passage through the chamber into a collection receptacle.

    Abstract: In one aspect, a gas chromatography-ion mobility spectrometry (GC-IMS) system is disclosed herein. In some embodiments, the GC-IMS system includes a GC column comprising an inlet and an outlet, and a sample delivery system in fluid connection with the inlet of the GC column and configured to provide a sample to the GC column. The GC column is configured to process the sample and produce a processed sample at the outlet. The GC-IMS system may also include an IMS tube. In some embodiments, the IMS tube includes a sample inlet in fluid communication with the outlet of the GC column, a wall that includes an orifice, and an outlet. The sample inlet may be configured to receive a portion of the processed sample. The IMS tube may be configured to analyze a second portion of pressurized gas.

    Abstract: A rotary encoder includes an electret unit, an electrostatic field sensor, and a controller. The electret unit generates an electrostatic field. The electrostatic field sensor is disposed proximate to the electret unit to sense a modulation of the electrostatic field that varies with rotation of one or more rotary components of the rotary encoder about a rotation axis of the rotary encoder. The controller is electrically coupled to the electrostatic field sensor to track activations of the electrostatic field sensor as the one or more rotary components rotate. The controller is configured to digitally encode a rotational position of the one or more rotary components based upon the activations.
