A gate valve includes a body, a stem, and a sensing bore. A subassembly includes a body, the body defining a sensing bore; and at least one of a vein and a plug in the sensing bore. A method of sensing an aspect of a water control system includes gaining access to the water control system through an access bore in a gate valve; at least temporarily removing water for testing from the access bore; and sensing an aspect of the removed water.

A multiply-redundant system that prevents a driver from starting and/or moving a vehicle if a compressed natural gas fill system is not correctly and completely disconnected from the vehicle. One or more sensors in combination with one or more optional microswitches combine to lock-out the vehicle's ignition or otherwise prevent it from starting and/or moving. For different levels of safety, different combinations of sensors can be used with the lowest level having a single proximity sensor sensing the presence or absence of a high-pressure fill hose. The highest level of safety being achieved by having separate proximity sensors on the fuel fill hose fitting, the gas cap cover and a manual safety valve along with a redundant microswitch. An optional override that may be restricted as to the number of times it can be used can allow starting with a faulty sensor in order to allow maintenance.

Systems, methods, and devices are described for providing a fluid control for an inflation system. The control directs fluid flow from an inlet to one or more outlets of the control. The outlets are independently connected in fluid communication with the inlet by through the control. The control allows a user to create a fluid path between the inlet and a selected outlet by positioning the control in an orientation corresponding to the desired outlet. Each outlet is independently connected in fluid communication with the inlet in various orientations of the control.

The invention provides methods for assessing one or more predetermined characteristics or properties of a microfluidic droplet within a microfluidic channel, and regulating one or more fluid flow rates within that channel to selectively alter the predetermined microdroplet characteristic or property using a feedback control.

A hydronic distribution system obtains, in real time, valve operating information from one or more valves arranged in a network, executes a speed determination algorithm which processes the valve operating information to determine a desired speed for one or more pumps to maintain a desired amount of process fluid flow of a process fluid to plural coils, and sets a speed of the one or more pumps, based on the desired speed for the one or more pumps that is determined.

An infrastructure monitoring assembly includes a nozzle cap defining an internal cavity; an antenna positioned at least partially external to the internal cavity; and the antenna covered with a non-metallic material. An infrastructure monitoring assembly includes a nozzle cap defining a first end and a second end, the first end defining a threaded bore configured to mount on a nozzle of a fire hydrant; a cover coupled to the nozzle cap opposite from the first end; an enclosure positioned at least partially between the cover and the first end, the enclosure at least partially defining a cavity; a monitoring device positioned within the cavity; and an antenna positioned between the cover and the first end of the nozzle cap, the antenna connected in electrical communication with the monitoring device, the antenna covered by a non-metallic material.
