Abstract: A method includes providing a cartridge and the cartridge includes a slot for receiving a microfluidic chip having a set of first channels. The cartridge also includes a set of second channels and each channel of the set of second channels is coupleable to a different channel of the set of first channels during use with the microfluidic chip. The cartridge also includes an indent configured for engagement and alignment of the cartridge during use. The method also includes inserting the cartridge into a device, such that the cartridge engages a first biasing member of the device configured for alignment of the cartridge in a first direction. The first biasing member is configured to bias movement of the cartridge into locking position with a notch of the device.

Abstract: The present disclosure includes devices, systems, and methods for autonomously landing unmanned aerial vehicles (UAVs) with collaborative information sharing and without a central coordinating entity. In one embodiment, the present disclosure includes an unmanned aerial vehicle including a communication interface, a memory; and an electronic processor. The communication interface is configured to establish a wireless communication link with one or more unmanned aerial vehicles. The electronic processor configured to autonomously coordinate landings at a landing strip with the one or more unmanned aerial vehicles to prevent collisions exchanging messages with the one or more unmanned aerial vehicles via the wireless communication link according to a collision avoidance protocol, and wherein the autonomous coordination occurs without a central coordination entity.

Abstract: A system includes a combustion chamber that has a throat, and a regulator for changing area cross-sectional area of the throat. The regulator includes a first piston in fluid connection with the combustor, and a second piston that is moveable with the first piston. The second piston at least partially defining the throat.

Abstract: A flush adapter, comprising an elongated spout having a bent tip on one end and a channel on the other end, the channel enclosed within a wider enclosed outlet with an opening outside of the channel. An example of a method for displacing fluids and particles from a non-readily accessible area using the flush adapter to prevent fluid stagnation and particle deposition, comprises: inserting the flush adapter into the non-readily accessible area; positioning the bent tip of the elongated spout to face the direction of the fluid flow along the main stream; continuously diverting a portion of the fluid flow downwards into the non-readily accessible area at a rate sufficient to displace the fluid inside the non-readily accessible area; and, exiting the displaced fluid through the opening on the enclosed outlet into the fluid flowing along the main stream.

Abstract: An improved bonnet assembly for a valve, comprising a hollow bonnet housing an actuator assembly comprising an actuator connected to a spindle, the hollow bonnet having a plurality of orifices to allow free entry and exit of a liquid such as a cleaning solution within the bonnet and to enable the liquid to thoroughly contact and exit the bonnet assembly without the need of disassembly. A handle is connected to the spindle of the actuator assembly within the bonnet to cause the upwards and downwards motion of the actuator assembly. The bonnet assembly connects to the rest of the components of the valve by connectors known in the art such as fasteners, clamps and retaining nuts or ring. The valve or parts of the valve such as the bonnet assembly or its components are made of performance engineered polymeric material to prevent corrosion and/or galling, and also reduce the weight and sometimes the cost of the valve without sacrificing quality and performance.

Abstract: A valve comprising a bonnet, an actuator for controlling the movement of a diaphragm situated between the bonnet and a valve body having an inlet port, an outlet port, a passageway connecting the inlet port and the outlet port for fluid flow, the valve body having an access receiving port for accommodating a device. The access receiving port is designed to accommodate any type of devices especially a test instrument which is usually a measuring or a sensing device. The access receiving port may be one or more than one. The proposed valve body can replace an existing valve body thereby avoiding the need to replace the entire valve. The access receiving port can have the same design or different designs. It is located either above the passageway of the valve body for a weir type valve or into the passageway of the valve body for a radial style valve.
