A sensing arrangement for indicating the depletion of a coreless roll of absorbent paper web material in a dispenser, the sensing arrangement includes a roll support for supporting an inner circumference of the coreless roll, the roll support extending along a longitudinal center axis, the roll support comprising at least one roll expanding portion extending over a part of the roll support length and having a maximum radial extension defining a first radius from the center axis, and at least one sensing portion, extending longitudinally over another part of the roll support length and having a maximum radial extension defining a second radius from the center axis, wherein the first radius is greater than the second radius by a sensing offset length, and a sensing element arranged to sense at the sensing portion the amount of web material remaining on the roll when arranged over the roll support length.

A hand cleaning fluid dispenser for dispensing fluid onto a user's hand includes a time of flight sensor to determine a distance of a hand of a user below an outlet of the dispenser from which the dispenser when activated dispenses the fluid and a controller to activate the dispenser to dispense the fluid from the outlet when the hand is sensed to be within a predetermined range of distances below the outlet.

A sheet product (e.g., napkin) dispenser may include an example calibration system and method for a product depletion curve for accurately determining a product level. An example sheet product dispenser includes a housing, a roll holder, a dispensing mechanism, a sensor, and a controller. The sensor is configured to emit a signal toward the product roll and receive a return signal. The controller is configured to receive a calibration product roll and operate the sensor to emit the signal and receive the return signal. The controller determines a brightness value of the return signal and determines a calibration value associated with the determined brightness value. The determined brightness value is within a range of brightness values associated with the calibration value. The controller adjusts a product depletion curve based on at least the determined calibration value and the determined brightness value. Additionally, example product level notification systems are provided herein.

A detection and reporting device for determining a usage event indicating a use of a piece of hygiene equipment, the detection and reporting device comprising a positioning section that allows determining positional information indicating a position of the detection and reporting device; a sensor section configured to sense over a time span an observable indicating a use of the piece of hygiene equipment and to generate usage event information on the basis of the sensed observable; and a reporting section configured to generate and transmit a message on the basis of said usage event information and on information allowing an association to said positional information.

Methods, systems and apparatus for determining product use by acoustically sensing actuations of product dispensers to determine how much product remains, and, optionally, alert a provider when low product states exist.

A product dispenser mounting system includes a dispenser holder body configured to support a product dispenser; and a mounting apparatus configured to fixedly mount on a support object and to removably connect to the dispenser holder body in one or more orientations such that dispenser holder body is maintained in a selected one of the one or more orientations when the dispenser holder body is connected to the mounting apparatus. The system may also include at least one actuation sensor configured to detect actuation of the product dispenser.

A piece of hygiene equipment includes a transmitting section configured to transmit an outbound radio signal carrying transmission payload data; a receiving section configured to receive an inbound radio signal carrying reception payload data; a processing section configured to transmit an outbound radio signal carrying specific transmission payload data and/or to receive an inbound radio signal carrying specific reception payload data for determining a communication partner to which outbound radio signals are to be transmitted and from which inbound radio signals are to be received; and a memory section. The processing section is configured to determine said communication partner and to store information on the determined communication partner in said memory section.

Methods, systems and apparatus for dynamically adjusting product use reporting schedules for dispensers to increase or decrease the frequency of such reports based on expected product use such as a date the dispenser is expected to be depleted.

A fluid dispenser including a contaminant sensor and methods of use of such a fluid dispenser to monitor contaminants either alone or in an array of similar dispensers within a facility.

A method and an arrangement for detecting a filling level in a tissue dispenser for dispensing portions of a continuous web of tissue from a tissue roll is adapted for use with. a tissue dispenser for dispensing portions of the continuous web of tissue from the tissue roll. The method comprises the steps of counting portions of the tissue dispensed by the tissue dispenser, determining an initial filling level depending on the counter data and an initial tissue type information, and determining a verified filling level depending on the counter data when a roll exchange of a tissue roll from a first tissue roll position to a second tissue roll position in the tissue dispenser has occurred.
