Abstract: Apparatus for staged startup of air-cooled low charged packaged ammonia refrigeration system includes motorized valves on condenser coil inlets, a main compressor discharge motorized valve, a bypass pressure regulator valve in the main compressor piping, check valves on the condenser outlets and speed control of the condenser fans. The condenser inlet motorized valves provide precise control of gas feed to the condensers, so pressure can build without collapsing the oil pressure. The condenser coil outlet contains inline check valves to prevent liquid backflow when a coil is isolated. The compressor discharge line contains a single motorized valve for regulating discharge pressure at start-up. The motorized valve in the compressor discharge piping also includes a bypass with a mechanical pressure regulator to allow precise regulation at the minimum discharge pressure. Once discharge pressure rises above the minimum setpoint, the condenser inlet solenoid coils will open one at a time.

Abstract: Introduced here is an approach to programmatically addressing the absorbance of light by analyte molecules whose binding, for example, to an interferometric sensor, is being monitored by an interferometric sensing system. A first light signal may be shone upon a biolayer over the course of a biochemical test, and the light reflected by the biolayer may form a second light signal that is detectable by a detector of an interferometric sensing system. Through analysis of the second light signal, the second light signal can be deconvolved into a reflection component and an absorbance component. If the principal component of the second light signal is the reflection component, then one algorithm may be employed to establish the binding magnitude. If the principal component of the second light signal is the absorbance component, then another algorithm may be employed to establish the binding magnitude.

Abstract: The invention pertains to a wearable pressure-applying device designed for user comfort and convenience. The device features multiple securing mechanisms for attachment to the user, including adaptable closures such as zippers. A manual or mechanical engagement system allows the user to adjust the constriction of the device, applying pressure as desired. Notably, the closure mechanisms do not extend across the entire vertical length of the wearable device, enhancing flexibility and comfort. The constriction mechanism employs either threaded or stringed lacing methods, with separable connections for user attachment and removal. An ergonomically contoured handle, easily attachable and detachable via a coupler, enhances usability. Additionally, a cord lock mechanism ensures precise pressure control, with a quick-release feature for instant pressure relief. Modular attachment options for both mechanical and cord-lock mechanisms offer versatility.
