Abstract: A system comprising for providing a virtual exposition floor where a first video conference and a second video conference may be established. The first video conference may provide a virtual exposition floor and the second video conference may be associated with a virtual expo booth within the virtual exposition floor. A plurality of participants may access at least the virtual exposition floor. The system may provide, information to generate a graphical representation of the virtual exposition floor, a first graphical representation of the virtual expo booth, and a plurality of avatars associated with the plurality of participants to one or more client devices. The system may also provide data associated with the first video conference, data associated with the second video conference, or data associated with the plurality of avatars.

Abstract: One example method includes receiving, at a video conference server, interaction data representing a plurality of participant interactions in a virtual expo with a plurality of virtual expo elements; storing the interaction data in a data store, the interaction data including a participant identifier, a virtual expo element identifier, and an interaction characteristic; determining one or more analytics for one or more of the plurality of virtual expo elements based on the interaction data; and causing the one or more analytics for one or more of the plurality of virtual expo elements to be displayed on a client device.

Abstract: An educational clock that includes a base, a minute number line chain including a plurality of minute links pivotably connected together, and an hour number line chain including a plurality of hour links pivotably connected together. The minute number line chain is adjustable between an annular shape configured to removably couple to the base and a linear shape. The hour number line chain is adjustable between an annular shape configured to removably couple to the base concentrically with the minute number line chain and a linear shape. The minute number line chain and the hour number line chain are approximately the same length when each is in its linear shape.

Abstract: A control system for a fluid analyzer is described. The control system has a processor executing processor executable code to: control a potentiostat to apply a first voltage potential sufficient to induce a first electrochemical reaction of a target analyte or a reaction byproduct of the target analyte in a sample of the calibration reagent and receive a first reading from the potentiostat; control the potentiostat to apply a second voltage potential insufficient to induce a second electrochemical reaction of the target analyte or a reaction byproduct of the target analyte in the sample of the calibration reagent and receive a second reading from the potentiostat; calculate calibration parameters using the first reading, the second reading and a multi-point calibration algorithm; and measure a target analyte concentration within the fluid sample using the calibration parameters.
