Abstract: A cannula for a vial adapter, having a pressure equalization device, includes a body having a first end, a second end positioned opposite the first end, and a sidewall extending between the first end and the second end. The body defines a central passageway extending from the first end to the second end of the body, with the body defining an opening extending through the sidewall of the body. The opening is in fluid communication with the central passageway. The second end of the body is closed.

Abstract: A method of confirming volume during dispensing of a liquid using pressure. The method includes attempting to dispense a volume of the liquid from a dispense port, measuring a pressure associated with the attempted dispense of the liquid and providing a measured pressure signal, determining a liquid dispensing start time and a stop time based on a slope of the measured pressure signal, integrating the measured pressure signal between the start time and the stop time to provide an integrated pressure value, and comparing the integrated pressure value to one or more preset threshold values. Liquid dispensing apparatus are provided, as are other aspects.

Abstract: Embodiments relate to detecting insufficient volume of a fluid aspiration. During aspiration of fluids, a pressure trace is obtained using a pressure transducer. An algorithm is applied to detect short shot (i.e., insufficient aspiration) instances utilizing characteristics of the pressure trace. In addition, the fluid probe geometry may be optimized to improve the accuracy of the detection, and temperature may be obtained to correct the pressure trace to account for fluid viscosity and thereby further improve the accuracy.

Abstract: A touch structure includes a conductive glass unit and a conductive film unit disposed on one side of the conductive glass unit. The conductive glass unit includes a glass substrate and a first patterned electrode layer. The glass substrate has a first surface and a second surface opposite to the first surface. The first surface has a first roughness, the second surface has a second roughness, and the first roughness is larger than the second roughness. The first patterned electrode layer is disposed on the second surface. The conductive film unit includes a transparent film and a second patterned electrode layer disposed on the transparent film.

Abstract: A method for forming a flexible transparent conductive film includes steps of: (a) electrospinning a first solution, which contains a polymer, a solvent and a metal ion-containing precursor, to form an polymeric fiber onto a soluble substrate; (b) providing energy to reduce the metal ion-containing precursor of the polymeric fiber, so as to form metal seeds on the polymeric fiber; and (c) placing the polymeric fiber together with the soluble substrate into a second solution, such that the soluble substrate dissolves in the second solution to form an electroless-plating bath and such that the polymeric fiber is subjected to electroless plating to form a metal coating from the metal seeds.

Abstract: To provide accurate determinations of volumetric flow rate and thus of total liquid volume transported over a given time period, two pressure transducers are disposed a predetermined distance apart along a conduit. Precise pressure measurement readings are generated from which volumetric flow rate can be derived with accuracy. Integration of the volumetric flow rate over time yields an improved measure of the total liquid volume that has flowed through the conduit during the respective temporal interval. The two pressure transducers are disposed along the conduit a predetermined distance apart with no obstruction or restriction in the conduit between the transducers. A controller can be used to determine the volumetric flow rate using the Hagen-Poiseuille Equation.
