Abstract: Systems and methods for heating, ventilation, and air conditioning (HVAC) systems with outdoor units having grills forming a support structure are provided. For example, an HVAC system may have an outdoor unit having a grill with vertical struts and horizontal struts which form one or more support structures, which may be in a rectangular shape for example. The support structure may receive a hook, clip, or other support portion of an HVAC maintenance device such as a refrigerant manifold gauge system or other HVAC gauge system. The support structure may be oriented in a direction perpendicular to a plane along which the grill extends, thereby avoiding any damage to the components of the outdoor unit by the maintenance device. The support structure and drill may be designed to withstand the weight of the maintenance device without deformation or damage.

Abstract: A method of monitoring a fuel system in a gas turbine engine. The method may comprise pumping fuel to a combustor from a fuel tank with a pump. The method may comprise controlling a flow of the fuel to the combustor with a metering valve disposed downstream of the pump and closing a spill valve disposed downstream of the pump, wherein the spill valve is closed in fixed increments and closing the spill valve increases a pressure in the fuel system. The method may comprise opening a pressure valve in response to the pressure in the fuel system being equal to or greater than a predetermined value, and capturing a degree of closing of the spill valve when the pressure valve opens.

Abstract: Disclosed techniques relate to orchestrating power consumption reductions across a number of hosts. A current value for an aggregate power threshold of a plurality of hosts may be identified. During a first time period, an aggregate power consumption of the plurality of hosts may be managed using the current value for the aggregate power threshold. A triggering event indicating a modification to the aggregate power threshold is needed may be detected. A new value for the aggregate power threshold may be determined based on the triggering event. During a second time period, the aggregate power consumption of the plurality of hosts may be managed using the new value for the aggregate power threshold.

Abstract: A lawnmower blade stamped or laser cut from a single metal sheet arranged as four blade arms of equal length on a single cutting plane that can resemble a cruciform shape. This design yields a uniform strength and reliability and does not rely on nuts, bolts, and multipart construction, and with minimal effect on overall weight. Each blade extends outward from a center mounting, possesses an offset, a sharpened leading edge and oppositely a deflection portion that is curved upward to produce a consistent suction force and circulating air flow useful during high moisture conditions. The leading edges all rotate in a single cutting plane to produce a level grass cut. The blade is capable of easy installation on a wide range of lawnmowers, but with a focus on commercial models and applications.

Abstract: An interposer interconnecting a first integrated circuit and a second integrated circuit includes active circuitry. The “active” interposer converts high-speed signals into lower-speed, but more parallelized, signals for transmission across the active interposer. The parallelized signals may be buffered or amplified at intervals while crossing the active interposer. The high-speed to low-speed, and back, conversions may be performed by an appropriately configured and controlled multiplexer/demultiplexer circuitry The supply voltages for some interposer circuits may be different than the supply voltages for the interfaces with the first and second integrated circuit. One or more of the interconnected integrated circuits may supply, and/or calibrate the supply voltages for the interposer circuitry. Timing signals provided by one or more of the interconnected integrated circuits may also be calibrated using circuitry on the active interposer.
