Abstract: A device for the uninterrupted administration of fluid to an animal body during a draw of bodily fluid, e.g., blood, is disclosed. A first fluid channel is configured to selectively transport IV fluid to an animal body and to draw a bodily fluid from the body. A sealing member for sealing a bodily fluid draw port defines a concave surface on a first end. The sealing member concave surface forms an interior surface portion of the first fluid channel. A connection member is configured to connect to a catheter to the first fluid channel and defines a concave distal end. A second fluid channel continuously provides IV fluid to a lumen coaxially located within the catheter. The concave surface and the concave distal end are shaped to create fluid flow patterns that quickly and completely remove residual bodily fluid remaining after a draw of bodily fluid is completed.

Abstract: This document describes improvements in range and reliability for wireless mesh networks implementing IEEE 802.11 networking technologies. Reducing the number of spatial streams, N, to a lower value at middle and far distance ranges using an optimized rate control algorithm, preemptively trades off a lower throughput limit for a higher link budget. This higher link budget provides longer range and higher RF link reliability by using an N×N spatial diversity of MIMO RF channels for maximizing link budget instead of network throughput.

Abstract: A method for decaying speech processing includes receiving, at a voice-enabled device, an indication of a microphone trigger event indicating a possible interaction with the device through speech where the device has a microphone that, when open, is configured to capture speech for speech recognition. In response to receiving the indication of the microphone trigger event, the method also includes instructing the microphone to open or remain open for a duration window to capture an audio stream in an environment of the device and providing the audio stream captured by the open microphone to a speech recognition system. During the duration window, the method further includes decaying a level of the speech recognition processing based on a function of the duration window and instructing the speech recognition system to use the decayed level of speech recognition processing over the audio stream captured by the open microphone.
