An assistance device for the use with a product dispensing device includes an engaging unit to the dispensing device, a locking unit for locking the dispensing device and configured to prevent or permit dispensing of the product, and a measurement unit for measuring a quantity of the product dispensed by the dispensing device. The locking unit remains unlocked for a predetermined period of time starting from a predetermined activation of the assistance device and then locks automatically at the end of the predetermined period. The locking unit locks automatically when a quantity of the product dispensed during the predetermined period reaches or exceeds a predetermined threshold.

A fluid application system includes a pump unit configured to pump a fluid to a fluid applicator. The fluid application system includes a sensor configured to sense a motion made by a user and generate a sensor signal indicative of the sensed motion. The fluid application system also includes a control system configured to identify a gesture based on the sensor signal and control the fluid application system based on the identified gesture.

A substrate processing method includes performing a developing processing on a substrate. The developing processing includes supplying a developing liquid on a surface of the substrate to form a liquid film of the developing liquid on the surface of the substrate; maintaining the liquid film on the surface such that development progresses; and performing, during the maintaining of the liquid film, a first processing of supplying a gas to an inner region located at an inner side than a peripheral region on the surface of the substrate and a second processing of supplying an adjusting liquid configured to suppress progress of the development on the peripheral region to adjust a degree of the development between the peripheral region and the inner region. The second processing is started after a start time of the first processing, and the second processing is ended after an end time of the first processing.

Proximity triggered water fountains may have proximity sensors configured to detect target(s), a processing unit communicably coupled to proximity sensors configured to transfer data related to the target(s) to the processing unit, nozzles and nozzle controllers, and collectors configured to receive water projected from the nozzles. The nozzle controllers may be controlled based on data received from the sensors. The nozzle controllers may be coupled to the nozzles of a water circulation system configured to adjust a water projection angle from the nozzles with respect to the ground. The water circulation system may use tank(s), pump(s), and supply and return line(s), with the nozzles, tank(s), pump(s), and supply and return line(s), being in fluid communication. The nozzles and collectors may be displaced a horizontal distance from each other such that outlets of the nozzles are not vertically above the collectors.

A scent delivery system includes scent delivery units that are configured to deliver scent at a variable scent level by being turned on and off successively according to a variable duty cycle. The scent delivery units are associated with corresponding base scent settings. The scent delivery system also includes a central controller configured to control the scent delivery units by generating command data based on a scenting schedule that indicates a desired activation time for more than one implicated scent delivery unit. The scenting schedule is configured to further indicate a scent level bias to be applied to the base scent settings that are associated with different of the implicated scent delivery units. The central controller is configured to generate the command data, based upon a variation in the scent level bias, that takes into account a corresponding variation to duty cycles that are associated with different of the implicated scent delivery units and to communicate the command data to the different implicated scent delivery units.
