Abstract: A dispenser system for a pressurized canister including an actuator including components such as an external housing, a valve having a top stem connector for attachment to an output hose, support pins, and a one way ball check valve having a stem fitting with an extended valve stem for engaging the pressurized canister, a pivoting actuator control or trigger, having a trigger return spring, to bias the trigger out of engagement with the valve, unless a stop pin is removed and the trigger is pivoted into operating engagement under compression of the trigger and trigger return spring by a user. The sensor may communicate with a mobile device to indicate when to stop dispensing contents from the canister.

Abstract: A system for indicating on an electronic device that the refrigerant being introduced by a user to an air conditioning system has reached its optimum fill level includes a sensor device having a main body, the sensor device being structured and disposed for measuring a range of data; a wireless transmitter on the sensor device, the wireless transmitter being in communication with the electronic device for wirelessly transmitting the range of data to the electronic device; an electronic application configured for use with the electronic device; and wherein the electronic application is structured and disposed for visually indicating to the user via the electronic device the transmitted range of data in real time and audibly indicating to the user via the electronic device when the transmitted range of data reaches a predetermined value.

Abstract: A dispenser system for a canister. The system includes an actuator and a cover that can prevent inadvertent actuation. The actuator may include a button, a stem connector and an actuator housing. The stem connector may include wings with a protrusion to create a snap-fit with the actuator housing, thereby holding the stem connector in place during operation of the dispenser system.

Abstract: A dispenser system for a canister. The system includes an actuator with universal and replaceable component parts. The actuator may include an actuator frame, plunger, control, stem connector and canister connector. The actuator may be within a housing form factor that holds additional sensors. The sensors may be removable components that are used as part of a larger canister system. The sensor may communicate with a mobile device to indicate when to stop dispensing contents from the canister. The sensor may additionally be designed to prevent inadvertent actuation until the sensor is removed.
