A dispenser comprising a cover housing, main housing, and base housing is provided. The cover housing includes an upper housing including a dispensing mechanism for dispensing cleaning solution from a holding reservoir. The main housing includes a cleaning solution storage reservoir, and a positive-displacement mechanism for electromechanically transporting cleaning solution from the storage reservoir to the holding reservoir. The base housing includes a ratcheting mechanism for causing the positive-displacement mechanism to rotate, and a power-spring mechanism for generating resistance against the ratcheting mechanism. The dispenser further includes a microprocessor configured to receive a signal indicating a sensing system has identified a dispense trigger, relay a signal to a pump motor to operate accordingly, determine that the holding reservoir is to be refilled, and actuate the positive-displacement mechanism to refill the holding reservoir. The dispenser further includes an electrical power system for supplying electrical power to electrical components of the dispenser.

A fluid dispenser having a temperature sensor that senses a temperature of an external surface presented by a user’s hand, and a pump mechanism that is configured to dispense fluid onto the user’s hand when the pump mechanism is activated. It is determined whether the fluid has been dispensed onto the user’s hand based, at least in part, on the temperature of the external surface presented by the user’s hand.

A bathroom modular device includes a base, including a lower surface, configured to be connected to a bathroom fixture and includes a module assembly having a plurality of modules, at least one module configured to be removably connected to the lower surface of the base. A managing system includes a bathroom modular device and a server communicably connected to the modular device. The bathroom modular device includes a base configured to be connected to a bathroom fixture and comprising a lower surface. The bathroom modular device also includes a module assembly comprising a plurality of modules, at least one module configured to be removably connected to a lower surface of the base. A bathroom managing method includes receiving a detection result obtained by a sensor; determining whether the received detection result satisfies at least one condition defined by a predetermined value; and generating a notification to perform corresponding maintenance work.

A pneumatically powered pump for liquid color adapted to fit partially within a liquid color container having a body portion of the pump within the liquid color container adapted to be mounted on the underside of the container lid and being a single piece of molded plastic overlying an aperture in the container lid.

A foam dispenser includes a housing, a drive motor, and a foam pump. The foam pump includes a pump housing, and a molded multi-chamber diaphragm. The molded multi-chamber diaphragm includes a liquid pump diaphragm having a liquid pump stem and two or more air pump chambers each having an air pump stem. The length of the liquid pump stem is longer than the air pump stem. The foam pump further includes one or more outlet valves, a mixing chamber, an outlet for dispensing foam wherein the outlet is in fluid communication with the foam cartridge; and an actuator for sequentially actuating the liquid pump chamber and the two or more air pump chambers, wherein there is lost motion between the actuator and the liquid pump diaphragm.

The invention refers to a soap recycling device that recycles solid soap bar remnants into purified liquid soap or purified reconstituted solid soap bars, depending on a user's selected mode of operation of the device. The soap recycling device includes a heat source that melts the solid soap remnants, a UV emitter that sterilizes the solid soap remnants, and a directional valve that selectively delivers the molten soap fluid to a first receptacle capable of storing the soap in liquid form and delivering it for direct usage, for instance for hand washing, and a second receptacle where the molten soap fluid solidifies and turns into a reconstituted solid soap bar. The device includes a user interface that allows selecting the desired operation mode to either liquid or solid soap formation. The device according to the invention is compact and versatile.

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.

Among other things, a dispensing device is described herein. A sensor component of the dispensing device includes an emitter (e.g., of an emitter array) in optical communication with a detector array for sensing objects disposed between the emitter and the detector array. An object detector is configured to identify a presence of an object between the emitter and the detector array based upon a readout signal generated by the detector array. A calibration component is configured to recalibrate the object detector responsive to determining that an obstruction is present between the emitter and the detector array. The recalibration allows the detector array and the emitter array to detect the presence of an object regardless of the obstruction. A material (e.g., soap, sanitizer, etc.) may be dispensed from the dispensing device responsive to detecting the presence of the object.

The presently disclosed subject matter is generally directed to a dispensing device that enables sensor-activated dispensing and playing of an auditory tone. The disclosed dispenser includes a housing comprising an internal reservoir that retains the product to be dispensed. The dispenser further includes one or more sensors that act as a motion detector to release a predetermined amount of product from the internal reservoir. The motion sensor further triggers the release of one or more predetermined auditory tones to be played from a speaker configured in the lower portion of the dispenser. Accordingly, users are encouraged to frequently use the dispenser, such as for hand washing and other activities.

Among other things, one or more systems and/or techniques for improving performance of a dispensing system are provided herein. The dispensing system may comprise an emitter and a detector. The emitter may be configured to transmit light (e.g., and/or one or more other signals). The detector may be configured to measure light, for example. The detector may determine a first measurement of light while the emitter is not transmitting light. The detector may determine a second measurement of light responsive to the emitter transmitting light. The detector may determine a third measurement of light based upon a comparison of the first measurement of light with the second measurement of light. The detector may be direct current (DC) coupled while determining the third measurement of light.
