Abstract: Methods of production of edible filamentous fungal biomat formulations are provided as standalone protein sources and/or protein ingredients in foodstuffs as well as a one-time use or repeated use self-contained biomat reactor comprising a container with at least one compartment and placed within the compartment(s), a feedstock, a fungal inoculum, a gas-permeable membrane, and optionally a liquid nutrient medium.

Abstract: Devices, systems, and methods for monitoring patient hemodynamic status, systemic vascular resistance, reversal of cardiac and respiratory rates, and patient respiratory volume or effort are disclosed. A peripheral venous pressure is measured and used to detect levels, changes, or problems relating to patient blood volume. The peripheral venous pressure measurement is transformed from the time domain to the frequency domain for analysis. A heart rate frequency is identified, and harmonics of the heart rate frequency are detected and evaluated to determine, among other things, hypovolemia or hypervolemia, systemic vascular resistance, and of cardiac and respiratory rates, and patient respiratory volume or effort.

Abstract: There is disclosed a chimney cleaner comprising a frame of rectangular cross-section narrower than the internal dimension of the chimney flue to be cleaned and having a substantial vertical height with spring-loaded pivotal flue side-scraping blades mounted to swing outwardly and upwardly from the sides of the frame to firmly contact and scrape the sides of a flue; preferably there are four blades with two oppositely disposed blades displaced vertically from the other two oppositely disposed blades whereby the blades may be substantially the full width of the flue and yet not interfere one with the other.
