A probe assembly configured to selectively restrict fluid flow through an outlet of a closed transfer system. The probe assembly has an elongate probe body with a top end portion, a bottom end portion, an outer wall, and an internal structure defining a fluid chamber extending from the bottom end portion to the top end portion. The fluid chamber has a fluid chamber inlet at the bottom end portion extending through the outer wall into the fluid chamber and a fluid chamber outlet at the top end portion extending from the fluid chamber through the outer wall. A probe tip with a cylindrical bore is configured to engage the top end portion of the elongate probe body and a probe tip outlet is configured to be in fluid communication with the fluid chamber outlet. A rotating head located circumjacent to the probe tip and adjacent to the probe tip outlet is configured to rotate about the probe tip. The rotating head having an inner surface, an outer surface, and a vane extending from the inner surface through the outer surface.

A dripping detection apparatus includes a cylindrical drip cylinder into which a nozzle is inserted from an upper side and that receives inside a liquid droplet dripping from a lower end of the nozzle, and a photo interrupter that has equal to or more than one light emitting element emitting light and equal to or more than two light receiving elements receiving the light, wherein the equal to or more than one light emitting element and the equal to or more than two light receiving elements are arranged at opposing or substantially opposing positions with the drip cylinder interposed between the elements and equal to or more than two light paths connecting the equal to or more than one light emitting element to the equal to or more than two light receiving elements are located at a lower side relative to the lower end of the nozzle.

Systems and methods for asset monitoring via orientation measurement, the system including a detection device, sensor, and control unit, the control unit configured with at least one operational condition and receiving information from the detection device and sensor, and the control unit determining or changing a mode of operation of the control unit based upon an evaluation of the received information in comparison to the operational condition. The system may optionally include a location sensing device. A method of monitoring an asset including: configuring a control unit with at least one operational condition; attaching a system to the asset; receiving, via the control unit, detection device information from the detection device, the detection device information including orientation information or motion information; evaluating the detection device information in comparison to the operational condition information; and determining or changing a mode of operation of the control unit based upon the evaluating.

Devices, systems, and methods are provided for monitoring water or other fluid consumption. For example, a fluid intake measurement device may provide highly accurate fluid consumption, which can be directly attached to a variety of fluid containers. The systems and methods herein also relate to the application of game psychology and mechanics to predict potential health issues and drive behavioral change for a healthier lifestyle and/or support motivational techniques for better healthcare conduct.

In one example, a method comprises measuring, by a processor, the flow rate of a cleaning fluid to clean at least a portion of a printing apparatus. The measured flow rate is compared to a desired flow rate. When the measured flow rate is outside of a first deviation from the desired flow rate, but within a second deviation from the desired flow rate, then the method in this example comprises changing the operation of a component of a printing apparatus.
