A heat exchange loop is installed within the foundation member for heat exchange with ground surrounding the foundation member. The heat exchange hoop is interconnected with a heat pump for providing heating or cooling to the building by heat exchange with ground surrounding the foundation member.

Abstract: A joining arrangement between a main tube and a side arm (5) in a side arm stent graft (1). The side arm (5) is stitched into an aperture (11) in the main tube and is in fluid communication with it. The aperture is triangular, elliptical or rectangular and the side arm is cut off at an angle to leave an end portion having a circumferential length equal to the circumference of the aperture. The side arm can also include a connection socket (76) comprising a first resilient ring (79) around the arm at its end, a second resilient ring (80) spaced apart along the arm from the first ring and a zig zag resilient stent (82) between the first and second rings. The zig-zag resilient stent can be a compression stent. Both the main tube and the side arm are formed from seamless tubular biocompatible graft material.

Abstract: A personal impact monitoring system is described herein comprising a monitoring station that receives impact events sent from personal impact monitors using a monitoring station receiver. The impact events which specify impact parameters associated with the impact events are stored in a data storage location associated with the monitoring station. Software operating on the operating station is configured to receive the impact events from the data storage location and to perform calculations based on the impact events to identify notable impact events.

Abstract: An entity modeling system integrated with a low-code application development platform may have a web/mobile-based user interface that can run in a browser environment on user devices ranging from desktop computers to smart phones. Users such as a subject matter expert may access an entity model designer tool of the system to model an entity. Responsive to user interaction with an entity composition function, the system may access a data store over a network and generate a view including a collection of entity building block(s) retrieved from the data store. Responsive to the user selecting a first entity building block from the collection to add to the entity, the system may automatically extend the entity to include settings of the first entity building block. The settings may include at least one of a property, permission, action, behavior, or resource to the entity.

Abstract: A portable monitor used to measure landfill gas, landfill well parameters, and/or gas from a well, biogas facility, subterranean location, and any other testing location. The portable fluid monitor is particularly useful in measuring gas pressures and compositions of gases.

Abstract: A stent graft for placement in a vessel of a patient, the stent graft that has a tubular body of graft material, the tubular body having a proximal inflow end, a distal outflow end, a main lumen therethrough, a longitudinal access, and a sidewall from the first end to the second end. At least one stent is along the length of the tubular body. One or more shaped recesses are formed of a concave or recessed portion of graft material that extends into the lumen of the stent graft. A fenestration is in the recessed portion with a fenestration and an internal branch extends from the or each fenestration toward the proximal end of the tubular body of graft material. The internal branch may have a tubular portion and a funnel portion, wherein the tubular portion extends into the main lumen and the enlarged funnel portion is attached to sidewall and forms the at least one shaped recess.
