Abstract: Systems and methods are disclosed for measuring the volume of liquid contained in a vessel. A sensor array comprising a plurality of sensors and a laser apparatus comprising one or more lasers can be positioned relative to each other such that lasers beams emitted from the laser(s) can be received by the sensor array. The vessel can be positioned such that each laser beam intersects the vessel at a certain predetermined height. A liquid level's height may be determined by the volume of liquid in the vessel. A refraction of a laser beam may be influenced by the presence or absence of liquid at that predetermined height, which could be the result of the liquid level's height being above or below that predetermined height. Readings from the sensor array may determine where refraction occurs, allowing ranges or values of the volume of liquid in the vessel to be extrapolated.

Abstract: According to some embodiments, a skin treatment system comprises a manifold assembly comprising at least one fluid connector to secure at least one treatment fluid container, a primary handpiece configured to hydraulically couple to the manifold assembly, wherein the primary handpiece is hydraulically coupled to the manifold assembly using at least one fluid conduit, and a flow control device positioned along the at least one fluid conduit, the flow control device configured to switch flow of treatment fluid from the at least one treatment fluid between the primary handpiece and a port, wherein the port is configured to be coupled to a secondary handpiece, wherein a vacuum source is configured to operatively couple to the system and selectively create suction along the primary handpiece.

Abstract: Various exemplary drug delivery device sensing modules and methods of using drug delivery device sensing modules are provided. In general, a sensing module can be configured to be attached to a drug delivery device configured to deliver a drug. The drug delivery device can be any of a variety of types of drug delivery devices, such as a syringe, an injection device (e.g., an autoinjector, a jet injector, and an infusion pump), a nasal delivery device, and an inhaler. The sensing module can be configured to gather data for one or more parameters related to drug delivery and to transmit data indicative of the gathered data to an external source configured to analyze the data received from the sensing module.
