Exemplary power systems for dynamically controlling a dispenser drive motor for dispensing soap, sanitizing or lotion. An exemplary soap, sanitizing or lotion dispenser includes a housing, a receptacle for receiving a container for holding a soap, sanitizing or lotion, a container of soap, sanitizing or lotion and a pump secured to the container. The exemplary soap, sanitizing or lotion dispenser includes a power source, a motor and an actuator that couples the motor to the pump. In addition, the exemplary soap, sanitizing or lotion dispenser includes pulse width modulation circuitry in circuit communication with the power source and the motor. Movement of the actuator one actuation cycle dispenses a dose of soap, sanitizing or lotion. The pulse width modulation circuitry provides a plurality of voltage pulses to the motor to move the actuator one actuation cycle.

The present application discloses liquid dispensers, refill units for liquid dispensers, liquid pumps, lost motion devices, and methods for installing a refill unit and lost motion device. In certain embodiments, a liquid dispenser of the present application comprises a container for holding a liquid, a pump housing connected to the container, a liquid or air chamber, and a piston movable in the liquid or air chamber. A connector is linked to the piston. The connector has a flexible portion for connecting to the piston and an attachment portion for attaching to an actuator of the dispenser. A restrictor is positioned between the flexible portion of the connector and the piston. Movement of the connector a first distance in a first direction results in lost motion between the actuator and the piston and continued movement of the connector a second distance in the first direction moves the piston with the actuator.

In an exemplary method of monitoring usage of an electronically operated dispenser, a dispensing mechanism is operated by an internal controller of the dispenser in response to user activation of an actuator of the dispenser in communication with the controller. In response to operation of the dispensing mechanism, dispenser data is written to an internal dispenser memory in wired communication with the controller, with the controller and the dispenser memory being electrically connected with and powered by a power source. The dispenser memory receives a wireless interrogation signal from an external reader and collects energy from the wireless interrogation signal. In response to receipt of the wireless interrogation signal, the dispenser memory wirelessly transmits the written dispenser data to the external reader, with the dispenser memory being powered by the collected energy.

One or more techniques and/or systems are provided for automatically forming a wireless sensor network, implementing power management for the wireless sensor network, and/or self-healing within the wireless sensor network. For example, hub devices, configured to forward messages through the wireless sensor network to a gateway device having access to a network, may automatically join and configure into the wireless sensor network by locating and connecting to master devices using signal frequencies representing numbers of hops to the gateway device. A hub device may be configured to transition between a low power sleep state for power conservation and an awakened normal operational state for transmitting timing signals according to a duty cycle, and thus the hub device may be capable of operating from a battery. If a hub device determines that a master device has become inoperable, the hub device may automatically search for a new master device.

A radio frequency identification (RFID) dispenser that includes low cost electronic components that can read and write to the tag of a refill cartridge. In one embodiment, the reader utilizes a multi band pass filter to convert the radio frequency identification into a digital signal that is processed by a controller to perform a dispensing function representative to the code of the tag. In another embodiment, the controller utilizes an internal comparator to convert the radio frequency identification into a digital signal that is processed by a controller to perform a dispensing function representative to the code of the tag. The dispenser in both embodiments also includes a pair of transistors that write to the RFID tag of the refill cartridge. A dispenser according to the invention also includes the capability to read and/or write to tags upon cartridges employed by the dispenser, and augmenting the operation of the dispenser as a function thereof. Additionally, a dispenser of variable size is presented that is adaptable, through adjustable partitions or a telescoping cup, to receive and maintain cartridges of various sizes.

A system for monitoring and recording hand hygiene performance is configured to monitor and record information generated by the operation of dispensers to assess behavior of a group to identify overall hygiene performance. The system includes a plurality of wireless communication devices, with a first number of the wireless communication devices being disposed within or adjacent to dispensers and operatively configured for sensing, monitoring, and reporting information about the status and operation of the dispensers. A hierarchal communication network for access to a central host database, a data processor, and a hygiene management software application operatively configured to create hygiene management reports of hand hygiene rate metrics based upon the monitored dispenser data and a method of providing a user interface. Based on the various computed hand hygiene rates, a hand hygiene improvement metric that identifies the improvement in hand hygiene rates over time is also calculated by the system.
