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.

Some embodiments provide a system and method for interfacing with an irrigation controller based on rainfall, the system comprising: an interface unit including a housing and a control unit within the housing and configured to: cause an interruption of one or more watering schedules executed by the irrigation controller, which is separate from the interface unit, based on signaling received from a rain sensor including hygroscopic material, when a sensed expansion of the hygroscopic material is above a set rainfall accumulation threshold parameter, the rain sensor being separate from the interface unit and the hygroscopic material being configured to expand in response to being contacted by the rainfall and to contract in response to an absence of the rainfall; and remove the interruption after a completion of a predetermined interval of time after a sensed contraction of the hygroscopic material indicative of a rainfall stop.

Described herein are several embodiments relating to modular irrigation controllers. In many implementations, the irrigation controllers are modular in that various functional components of the irrigation controller are implemented in removable modules that when inserted into position within the controller, expand the capabilities of the controller. Also described are various different types of expansion modules that may be coupled to the modular controller, having as variety of functions and features, as well as related methods of use and configuration of these modules in the controller. In some embodiments, a serial communication bus is provided between a control unit of a modular irrigation controller and an expansion module.

A wireless system is provided for monitoring environmental, soil, or climate conditions and/or controlling irrigation or climate control systems at an agricultural or landscape site. In some embodiments, the wireless system includes at least one wireless control nodes for monitoring environmental, soil, or climate conditions and/or for controlling one or more irrigation or climate control systems at the site. The wireless system also includes a web based application or a cell phone application and a gateway coupled to a communications network. The communications network is configured to transfer data to and receive remote control commands or queries from an end-user.

A method and system for co-ordinating control of a plurality of sensorless devices. Each device includes a communication subsystem and configured to self-detect one or more device properties, the device properties resulting in output having one or more output properties. The method includes: detecting inputs including the one or more device properties of each device, correlating, for each device, the detected one or more device properties to the one or more output properties, and co-ordinating control of each of the devices to operate at least one of their respective device properties to co-ordinate one or more output properties for the combined output to achieve a setpoint. In some example embodiments, the setpoint can be fixed, calculated or externally determined.

Apparatus and methods are described for automatically performing set-up steps for flow cytometry operations. The invention provides for the spatial determination of a flow stream and the subsequent automatic alignment of analysis devices and/or collection vessels. The automatic determination of flow stream properties provides for the automatic configuration flow cytometer parameters.

The present disclosure describes a hybrid, wireless sensor network architecture for monitoring, operating, controlling, or maintaining a fluid delivery and distribution system. The architecture includes intelligent fittings locatable at almost any location within the system and that are configured with sensor modules to make measurements of characteristics of a fluid passing therethrough or of component parameters, and with wireless communication modules to wireless communicate the measurements. The intelligent fittings may be used, via strategic location, to convert unintelligent components of the system into intelligent components at a cost lower than that required to replace the unintelligent components with intelligent components. The intelligent fittings may also replace unintelligent fittings to provide supplemental data corresponding to fluid characteristics at desired locations of a fluid delivery and distribution system. The architecture further includes a digital twin of a hybrid, wireless sensor network that may downloaded to controllers for use.

A system of household appliances is configured to provide services according to user identity. The system includes a first appliance, a server or other network device, and a second appliance. The first appliance is configured to collect sensor data associated with an identity of a user. The server or other network device is configured to receive the sensor data from the first appliance and analyze the sensor data to determine the identity of the user. The second appliance is configured to provide a device function to the user based on the identity determined from the sensor data collected by the first appliance.

A flow rate control method performed in a flow control device 100 having a first control valve 6 provided in the flow path, a second control valve 8 provided downstream of the first control valve, and a pressure sensor 3 for measuring a fluid pressure upstream of the first control valve and downstream of the second control valve, comprises, at the time of flow rate raise, a step (a) of determining a pressure remaining downstream of the first control valve by using a pressure sensor in a state of closing the second control valve, and a step (b) of controlling the pressure remaining downstream of the first control valve by adjusting the opening degree of the second control valve on the basis of the output from the pressure sensor, and flowing a fluid at the first flow rate downstream the second control valve.

A virtual reality (VR) olfactory apparatus includes an odorant saturation chamber having an inlet and an outlet. At least a portion of the odorant saturation chamber includes a plurality of beads and a liquid. The liquid includes an odorant concentrate. The inlet extends into this portion of the odorant saturation chamber. The VR apparatus also includes a mass flow controller to generate an air flow to the inlet of the odorant saturation chamber such that the air flow passes through the portion of the odorant saturation chamber to form an odorant. The air flow passes the odorant through the outlet of the odorant saturation chamber. The VR apparatus further includes a nose chamber connected to the outlet and configured to receive the odorant.
