Abstract: Described herein are examples of a perforating device for perforating a textile material, such as carpet or textile underlayment. In an example, the perforating device includes a multi-blade assembly rotationally driven by a motor. The blade assembly can be coupled to a rotary shaft such that the blades rotate with the shaft. The blades can include alternating teeth and gaps on their outer edges to create a plurality of parallel perforated cuts. Spacers can be positioned between the blades to separate them a predetermined distance. An anvil can be positioned below and adjacent the blade edges such that the teeth of the blades touch or nearly touch the anvil surface. The perforating cuts produce a textile that can be customized in terms of its size and shape at an installation site by hand, and without the need for any specialized tools or equipment.

Abstract: Systems and methods for using a daughter board to deliver power from the power supply to a chip on a host board, where power is converted to a desired voltage (e.g., from a higher voltage to a lower voltage), provided to a daughter board, processed as needed on the daughter board, and delivered to the host board at locations close to the chip. The power is delivered from the daughter board to the host board through connective electrical components which may comprise decoupling capacitors that are soldered between the boards to provide minimized transient response characteristics as well as structural support between the boards, or coaxial connectors that provide reduced inductance and are secured between the boards by structural posts.

Abstract: A modular hydronic system core system and method includes a hydronic fluid flow conduit with closely spaced tees and distribution supply and return portions on a substrate. A supply manifold is coupled to branch feeders that support a circulator pump or zone valve. An ECM circulator along the conduit includes a Bluetooth transmitter to capture and transmit fluid flow rate and pressure. A return manifold includes branch returns with purge/shutoff valves. The branch feeders and returns are connectable to a distribution system having heating elements. Air and dirt separators, and an iron remover remove air, dirt and iron from the fluid. An expansion tank bracket supports a pressure gauge and expansion tank. A zone relay is coupled to the ECM circulator and zone valves on the branch feeders, and includes thermostat terminals. The zone relay captures inputs from the thermostats to control operation of the ECM circulator and zone valves.
