A hydronic distribution system includes self-regulating valves networked together and operable to share valve temperature and valve position information with a microprocessor or other type of controller. The microprocessor runs one or more algorithms that process the temperatures and positions of the valves and then computes a desired speed for one or more variable speed pumps within the system. Controlling the pumps to operate at the desired speed and still maintain the correct amount of process fluid flow needed by the system reduces the overall energy use of the hydronic distribution system, saves on the operational lives of the pumps, and increases system efficiency.

A method and apparatus for self-calibrating control of gas flow. The gas flow rate is initially set by controlling, to a high degree of precision, the amount of opening of a flow restriction, where the design of the apparatus containing the flow restriction lends itself to achieving high precision. The gas flow rate is then measured by a pressure rate-of-drop upstream of the flow restriction, and the amount of flow restriction opening is adjusted, if need be, to obtain exactly the desired flow.

A flow imaging and monitoring system for synchronized management of wide area drainage that includes an interposer for supporting monitoring and management equipment in a manhole, a module for illuminating water flowing in pipes at the base of the manhole, a module for monitoring responses to reflected light, a sealed and rechargeable battery pack, and a data analysis and management system to interpret data streams in real time. The interposer can be adjusted to fit the diameter of the manhole and can be adjusted to be placed under the manhole cover. The module for illuminating the flowing water can be adjusted to generate various frequencies. The support structures for the modules can be adjusted for varying pitch, roll and yaw with respect to the manhole. The data analysis and management system is supported by cloud computing.

A pump system for a water supply mains has at least one pump device, a pressure detecting sensor at the pressure side of the pump device, a flow detecting sensor of the pump device, several pressure sensor units (D) remote arranged remotely from the pump device in different part regions of the mains, and a pump control device. The control device includes a model formation module designed in each case to produce a model (A) representing pressure loss from the pressure sensor to the position of the respective pressure sensor unit (D), based on several pressure measured values of at least two pressure sensor units (D) for the at least two associated part regions. The control device is designed for regulation of the pump device based on produced models (A), as well as to a corresponding method for regulation of a pump device in a water supply mains.

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.

An infrastructure monitoring assembly includes a nozzle cap, the nozzle cap comprising a metallic material; an antenna cover, the antenna cover attached to the nozzle cap, the antenna cover comprising a plastic material, the antenna cover defining an antenna cavity; and an antenna extending into the antenna cavity. An infrastructure monitoring assembly includes a fire hydrant, the fire hydrant defining a nozzle; a nozzle cap, the nozzle cap comprising a metallic material, the nozzle cap attached to the nozzle and sealing the nozzle; an antenna cover attached to the nozzle cap, the antenna cover comprising a plastic material, the antenna cover defining an antenna cavity; and an antenna disposed within the antenna cavity.

A versatile container a versatile pipe section comprising a sleeve and a tube inserted into the sleeve, the tube being held in place using a first capping element at a first end, at least one mounting element in a middle portion and a second capping element at a second end. The first and second capping elements are provided with an opening of a diameter corresponding to the diameter of the tube for allowing liquid or gas to flow through the tube. Also, a versatile container comprising a sleeve, at least one liquid or gas holding compartment adapted to be positioned within the sleeve, the at least one compartment being held in place using at least one mounting element. The sleeves are adapted to hold the contents of the tube or the at least one compartment in case of a leak.

An intravenous (IV) set system comprising a primary IV set defining a primary flow line of the IV set system. The primary flow line can include multiple access points along its length and feeds to a merging fluid pathway proximate to the distal terminus of the primary IV set. At least one secondary IV set with corresponding flow lines can be separably joined to the primary IV set to cause the secondary flow lines to be in fluid communication with the primary flow line. At least one of the IV sets can have a unique set of uniform marking indicia to facilitate rapid identification of the IV sets from other IV sets within the IV set system. Such marked and identified primary and/or secondary IV sets can be allocated to specific medical functions and/or can be for use by specific medical personnel to thereby minimize risk of error in administration of an IV to a patient. The IV set system can further comprise a merging fluid pathway about a primary IV set.

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.
