A dispenser of liquid products for sanitization, such as bactericides, germicides, disinfectants, alcohol gel, moisturizers, among others, featuring innovative construction characteristics which distribute the product onto the user's hands or onto surfaces of various objects, via spraying in micro droplets, enabling a uniform distribution, suitable to be installed in public environments such as restrooms, restaurants, malls, offices and commercial facilities.

Automatic electric actuation of the pump of a liquid dispenser apparatus is provided by a stepper motor having a threaded hollow liquid-conducting tube positioned therein and configured such that motor drives the hollow tube up and down in response to supply of a plurality of electrical pulses thereto. A lower end of the hollow tube is constructed to inter-fit with a stem of the pump such that driving the hollow tube up and down creates a pumping action.

A method of applying a coating product on a surface of a part, this method being carried out using an applicator including at least one row of nozzles, among which at least the first nozzle in the row includes a valve, the method including moving the applicator in a first direction to apply a first layer of coating product, and moving the applicator in a second direction substantially parallel to the first direction to apply a second layer of coating product adjacent to the first layer, comprising measuring at least one application distance of the first nozzle from a point in front of the first nozzle on a path of the applicator, and based on the measured application distance, opening or closing the valve.

A control unit performs control such that the mist is started to be sprayed in a horizontal direction or a downward direction from a spraying unit toward a subject on a basis of detection of the subject by a detection unit.

A dispensing system for dispensing a fluid, the fluid being water or a water-based mixture, includes a dispensing unit and a cleaning unit. The dispensing unit includes a connection unit for connecting the dispensing unit to a supply of the fluid, a dispensing head for dispensing the fluid, and a flexible hose for guiding the fluid from the connection unit to the dispensing head. The cleaning unit includes a cleaning attachment unit for attaching the cleaning unit to the connection unit, a cleaning fluid delivery unit configured to deliver cleaning fluid to the dispensing unit via the cleaning attachment unit, and a receptacle unit configured to accommodate the dispensing head and to receive fluids exiting the dispensing head.

A handheld fluid spraying system includes a pump assembly configured to provide a pressurized liquid and a handheld fluid sprayer. The handheld fluid sprayer comprises a fluid inlet configured to receive the pressurized liquid, a spray tip having an outlet through which the pressurized liquid exits the handheld fluid sprayer to be applied to a surface, a trigger configured to control flow of the liquid through the handheld fluid sprayer, and a sensor configured to detect the liquid and to generate sensor data indicative thereof, the sensor being selected from the group consisting of an infrared (IR) sensor, a thermal imager, and a UV sensor. The handheld fluid spraying system further comprises a controller configured to determine a characteristic of the liquid based on the sensor data and to generate a control output based on the determined characteristic.

A soap dispenser can be configured to dispense an amount of liquid soap, for example, upon detecting the presence of an object. Certain embodiments of the dispenser include a housing, reservoir, pump, motor, sensor, electronic processor, and nozzle. In certain embodiments, the sensor can be configured to generate a signal based on a distance between an object and the sensor. In certain embodiments, the electronic processor can be configured to receive the signal from the sensor and to determine a dispensation volume of the liquid. The dispensation volume can vary as a function of the distance between the object and the sensor. The processor can be configured to control the motor to dispense approximately the dispensation volume of the liquid.

An automated drywalling system network that including one or more automated drywalling systems that each has a robotic arm. The automated drywalling system network can also include a computational planner that generates instructions for the one or more automated drywalling systems to perform two or more drywalling tasks associated with a target wall assembly. The two or more drywalling tasks can include a hanging task that includes hanging pieces of drywall on studs of the target wall assembly; a mudding task that includes applying joint compound to pieces of drywall hung on studs of the target wall assembly; a sanding task that includes sanding joint compound applied to the pieces of drywall hung on studs of the target wall assembly; and a painting task that includes painting sanded the joint compound applied to the pieces of drywall hung on studs of the target wall assembly.

A makeup machine includes a spray head, a main body, an arched track, and vertical support. The spray head has a receptacle to receive a spray cartridge containing a skin spray. The main body houses a controller circuit that controls a position of the spray head with respect to a target of the skin spray. The arched track has a curved shape on a horizontal plane, and the vertical support is attached to the arched track. The controller circuit causes the spray head to slide along the arched track, and adjusts a height of the vertical support to cause the arched track and the spray head to move up and down. The makeup machine also includes a linear track controlled by the controller circuit to adjust a horizontal distance between the spray head and the target.
