An apparatus and associated method for operating a horizontal surface pump apparatus, including a motor operating a pump to pressurize a fluid inside the pump. A flow controller executes computer instructions stored in memory that define a selected flow rate of the fluid flowing out of the pump based on a flow profile trajectory stored in memory and related to an observed parameter of the fluid. A motor controller executes computer instructions stored in memory that map the selected flow rate and an observed head pressure of the fluid to a selected motor speed via a transformation function stored in memory, and that operate the motor at the selected motor speed.

A sanitary equipment and a control method thereof are provided. The sanitary equipment includes a main body having an opining, a cover body movably disposed at the main body, an electric motor driving the cover body to move, an auxiliary apparatus disposed at the main body and a control circuit coupled to the electric motor and the auxiliary apparatus. In response to operation or wireless remote control, the control circuit controls the electric motor to drive the cover body to open the opening and turn on the auxiliary apparatus in a first process. In a second process, the control circuit controls the electric motor to drive the cover body to close the opening, and turns off the auxiliary apparatus at the same time. Sequences, numbers of steps of the first process and the second process are different. Accordingly, the sanitary equipment with multiple functions and convenient use is provided.

Controlling heating and cooling in a conditioned space utilizes a fluid circulating in a thermally conductive structure in fluid connection with a hydronic-to-air heat exchanger and a ground heat exchanger. Air is moved past the hydronic-to-air heat exchanger, the air having fresh air supply and stale air exhaust. Sensors located throughout the conditioned space send data to a controller. User input to the controller sets the desired set point temperature and humidity. Based upon the set point temperature and humidity and sensor data, the controller sends signals to various devices to manipulate the flow of the fluid and the air in order to achieve the desired set point temperature and humidity in the conditioned space. The temperature of the fluid is kept less than the dew point at the hydronic-to-air heat exchanger and the temperature of the fluid is kept greater than the dew point at the thermally conductive structure.

A solenoid device including pressure altering means for altering an output pressure of the solenoid device; and an actuator for providing an actuating signal to said pressure altering means; wherein the solenoid device further includes a sensor arranged to sense a control value of the solenoid device, and a controller which receives a request and is arranged to control delivery of power to the actuator with feedback from the sensor until the control value meets the request.

An onboard apparatus, system, and method for automatically loading into or unloading from a bulk transport or other container and evaluating characteristics of a liquid during the loading or unloading, that dynamically monitors and evaluates characteristics of the flow, particularly density, which are used to determine other characteristics and values of the load, namely, presence of contaminants such as water, solids, out of specification conditions, etc. to enable accurately measuring volume, mass, and/or quality of the load, and optionally to automatically responsively perform certain operations, for example, to signal an operator, cease loading, segregate and/or return all or portions of the load, if contaminated or out of specification, and which facilitates control remotely, as well as for qualifying for government certification for custody transfer.

Water tap (2) or water valve assembly is provided which has biometric recognition means (20) provided on or associated with the same. The biometric recognition means (20) are arranged such that operation of the water tap (2) or water valve assembly and/or operation of one or more functions of the water tap (2) or water valve assembly takes place only upon recognition or a positive match of one or more biometric features of a user.

Systems, methods, and software program products for dispensing chemical solutions. A controller receives a signal from a pressure sensor indicative of a pressure of a diluent. The controller determines an expected flow rate of the diluent through an eductor based at least in part on the pressure of the diluent. The controller may further determine an expected concentration of a chemical product in the solution dispensed from a discharge port of the eductor. Based on the expected flow rated and concentration of the chemical product, the controller determines a duration of a dispense stage of a dispensing operation required to dispense a predetermined dose of the chemical product. The controller then causes the diluent to flow through the eductor for the determined duration of the dispense stage. A check valve on the output of the eductor prevents dissimilar chemicals from mixing and reduces a response time of the eductor.

A multiple fluid model tool for multi-dimensional fluid modeling of a biological structure is presented. For example, a system includes a modeling component, a machine learning component, and a three-dimensional health assessment component. The modeling component generates a three-dimensional model of a biological structure based on multi-dimensional medical imaging data. The machine learning component predicts one or more characteristics of the biological structure based on input data and a machine learning process associated with the three-dimensional model. The three-dimensional health assessment component that provides a three-dimensional design environment associated with the three-dimensional model. The three-dimensional design environment renders physics modeling data of the biological structure based on the input data and the one or more characteristics of the biological structure on the three-dimensional model.

A computer-implemented method includes controlling water separation in a hydrocarbon stream flowing through a separator train including one or more separator vessels located upstream of a dehydrator by manipulating a demulsifier flowrate added to the separator train by: receiving data from a real-time process test of the separation train, estimating model fit parameters to the data to generate a water separation profile (WSP) correlating water draw-off and demulsifier flowrate for the separation train, determining a maximum and a minimum demulsifier flowrate from the WSP, receiving, from an operator, a separation performance for a target water separation value entering the dehydrator downstream from the separator train, and adjusting the demulsifier flowrate according to the WSP to achieve the target water separation entering the dehydrator.

A controlled pourer that may include a locking mechanism for locking the controlled pourer to a bottle; a communication module; a flow control mechanism that is configured to control an output of fluid, during a liquid consumption iteration, from the bottle under a control of one or more commands received by the communication module; and a flow meter for monitoring an amount of fluid outputted by the flow control mechanism during the fluid consumption iteration. The communication module is configured to output information regarding the amount of fluid consumed during the fluid consumption operation. Once locked to the bottle the controller pourer prevents a bypass of the fluid control mechanism.
