Abstract: In an example implementation, a reagent storage system for a microfluidic device includes a microfluidic chamber formed in a microfluidic device. A blister pack to store a reagent includes an electrically conductive membrane barrier adjacent to the chamber. A thinned region is formed in the membrane barrier, and a conductive trace is to supply electric current to heat and melt the thinned region. Melting the thinned region is to cause the membrane barrier to open and release the reagent into the chamber.

Abstract: An example apparatus may include a hub and a control unit. The hub may include a first input/output (I/O) connection, a second I/O connection, and a third I/O connection. The first I/O connection may connect to a peripheral device of a video conferencing system, the second I/O connection may connect to a first conferencing application, and the third I/O connection may connect to a second conferencing application via a video conferencing controller connected to the third I/O connection. The control unit may reconfigure the hub to change a connection of the peripheral device from the first conferencing application to the second conferencing application. The control unit may reconfigure the hub based on a location of a computing, wherein the second conferencing application is executed on the computing device.

Abstract: An example wireless networking device (e.g., Access point) dynamically managing preamble puncturing for OFDM-based communications. The wireless networking device determines first criteria of a signal quality and further determines to allow preamble puncturing, wherein the signal quality of the determines the occupancy of a subchannel. Based on the determination to preamble puncture, apply dynamically, preamble puncturing to an adjacent subchannel. The wireless networking device further monitors the subchannel signal quality and determines based on a second criteria, an amount of bandwidth useable from an adjacent bandwidth. The wireless networking device, based on the second criteria, dynamically allocate bandwidth from the adjacent subchannel.

Abstract: Calibration data is obtained relating to a printed thickness of an elongate member as a function of position within a container for containing a print medium in an additive manufacturing printer. An object model is obtained representing an object to be printed, the object having elongate members. A position of the object to be printed within the container is determined and respective positions within the container for the elongate members of the object are determined from the determined position of the object. The obtained object model of the object is changed to an amended object model in which the elongate members have respective thicknesses based on the determined respective positions within the container for the elongate members and the calibration data.

Abstract: A multi-fluid kits for three-dimensional printing can include a fusing agent and a tinted anti-coalescing agent. The fusing agent can include water and an electromagnetic radiation absorber that absorbs radiation energy and converts the radiation energy to heat. The tinted anti-coalescing agent can include an aqueous liquid vehicle, a colored dye dissolved in the aqueous liquid vehicle, and a polyelectrolyte. The polyelectrolyte can have a weight average molecular weight from about 1,000 Mw to about 8,000 Mw, the polyelectrolyte can be water-absorbent at a water to polyelectrolyte weight ratio from about 2:1 to about 1,000:1, and about 90 wt % to 100 wt % of the polyelectrolyte can be dissolved in the aqueous liquid vehicle.
