According to some embodiments, a bottle is disclosed. The bottle includes a main storage area, a dosage storage chamber, and a dispensing neck. The dosage storage chamber is coupled to the main storage area via a fluid channel. The dispensing neck extends from the dosage storage chamber for dispensing a content of the bottle. In a case that the dispensing neck is positioned parallel with the ground, the content of the bottle in the dosage storage chamber will not flow into the dispensing neck.

The disclosure relates to systems for distributing alcohol-containing gasoline. The systems herein facilitate the combination of gasoline blendstocks and alcohols to create finished gasoline products. The systems herein also measure the volumes and other characteristics of the gasoline blendstocks and alcohols and feature computers and controllers that can calculate the gross and net volumes of liquids, including the net volume of finished gasoline products.

A system and method for dispensing fluid including a pump having a stepper motor operably connected to a pump head. The pump head has an inlet and an outlet. The inlet is adapted to be in fluid communication to a fluid reservoir. A controller is operably connected to the motor. The controller drives the motor wherein a speed and an acceleration of the stepper motor is selected to overcome adhesion between the dispense tip and the dispensed fluid. A dispense tip formed of a hydrophobic material is in fluid communication with the outlet of the pump head.

An improved fluid transfer accuracy, information collection, and overall management. A system may utilize a pump to transfer fluid from a source to a target vessel, a meter for measuring an amount of fluid transferred, a density meter to detect actual fluid density, and a control unit to determine actual fluid transfer amount based on density. As an example, a fluid flow meter can be coupled with a flow conduit to determine fluid volume, along with the density meter to detect real-time density of transferred fluid. During a fluid transfer event, such as aircraft refueling, LPG fueling, or other refined fuels or valuable liquids, fluid volume can be converted to fluid weight in real-time based on actual density. The real-time fluid weight can be used to determine if a target fluid weight has been reached, and fluid flow can be shut off at the appropriate time.

An autonomous refilling system for a mobile security robot is disclosed. The system includes a refill station having a fluid reservoir, a pumping mechanism, and a docking interface configured to align with a refill port on the robot. A sensor system verifies docking, while a fluid level sensor on the robot monitors onboard reservoir levels. A control module initiates and terminates fluid transfer based on docking status and fluid conditions. In various embodiments, the station incorporates redundant sealing, leak detection, thermal monitoring, and multi-reservoir support for different fluids such as water, invisible ink, or scent-based deterrents. The system may be integrated with a centralized management platform that coordinates refilling across multiple robots and stations.
