Abstract: Disclosed are methods and apparatuses to provide a redo repeater that allows for no data loss protection without the performance impact to the primary database even when a significant geographical distance separates the primary and standby databases. The Repeater is a lightweight entity that receives redo from the primary database with the purpose of redistributing that redo throughout the primary/standby system configuration. The Repeater able to extend no data loss protection and switchover functionality to terminal standby databases even though the primary database does not need to have a direct connection with those destinations.

Abstract: In order to establish a mesh network, an electronic device may iteratively identify one or more mesh-network nodes and may determine associated duty-cycle ratios based on communication with the one or more mesh-network nodes. In particular, the electronic device may select candidate mesh-network nodes based on estimated throughput metrics of their communication with a root device in the mesh network. Then, for each of the candidate mesh-network nodes, the electronic device may associate with a given candidate mesh-network node, and may measure the throughput of the given candidate mesh-network node during a time interval by communicating packets. Based on comparisons of the measured throughputs, the electronic device may identify the one or more mesh-network nodes in the candidate mesh-network nodes and may determine the associated duty-cycle ratios. Subsequently, the electronic device communicates information with the root device via the one or more mesh-network nodes based on the duty-cycle ratios.

Abstract: An automatic ventilator adjusting system has a three-way inline adapter coupled to 1) a breath sample line, 2) a ventilator (either invasive or non-invasive), and 3) a patient. The breath sample line is coupled to a Gas Exchange Monitor (GEM) and preferably has a female Luer lock end. Ventilator settings can be automatically set and/or adjusted using 1) an algorithm preferably having a feedback loop and 2) inputs including one or more of: gPaO2™ (calculated arterial partial pressure of O2 by GEM), oxygen deficit, gPaCO2™ (calculated arterial partial pressure of CO2), gPaCO2™/gPaO2™, PiO2-PETO2, TLC (Total Lung Capacity), FRC (Functional Residual Capacity), and Vd/Vt (deadspace ratio). Preferably, one or more of the inputs (e.g., gPaO2™ gPaCO2™, and oxygen deficit) are obtained non-invasively from a patient's normal breathing gas samples as calculated by MediPines Gas Exchange Monitor (GEM).

Abstract: The present invention provides a method for obtaining respiratory gas in steady state breathing with minimum contamination of atmospheric air. The breathed air is obtained using a breathing tube having two openings, a breathing opening with an oval shape and an atmospheric opening with a circular shape. The breathed air is passed through a breathing passageway between two openings with laminar flow, and further passed through a sampling hole disposed on the atmospheric opening and coupled to a sampling tube extended halfway into the breathing passageway through the sampling hole.

Abstract: The present invention provides a breathing tube assembly for measuring respiratory gases from a patient. The breathing tube has been optimized for the side-sampling of respiratory gases from steady-state breathing. The breathing tube assembly comprises a breathing tube having three openings, breathing, atmospheric and sample openings. By using breathing and atmospheric openings, a patient can breathe normally to reach to steady state breathing. The sampling tube is coupled with a transport tube, allowing the breathed air traveling through the transport tube. An end of the transport tube away from the breathing tube is connected to a monitor to analyze patient's breathing air.
