Abstract: Exemplary foam-at-a-distance systems include a spout, a container, and a foam generator having a suck-back mechanism located within the spout. The system includes a liquid pump chamber, an air pump chamber, a liquid conduit and an air conduit. The foam generator has a differential bore housing. The differential bore housing has a first portion with a first inside bore and a second portion with a second inside bore, wherein the first inside bore has a smaller diameter than the second inside bore. A piston having a seal extending from the piston that is in contact with the second inside bore is also included. A mixing chamber is located in the large bore. Movement of the seal in an upstream direction provides negative pressure in the second mixing chamber and draws in fluid from the outlet.

Abstract: An exemplary embodiment of a modular people counter includes a base and a communications module. The base has a people counter processor, memory, a power supply having one or more batteries, a passive sensor that detects whether a badge and/or a person has entered into a selected area and is within the sensing range and a first connector. The first connector is in circuit communication with the people counter processor. The communications module has a second connector for connecting to the first connector and wireless communications circuitry. The wireless communications module is configured to receive one or more signals from the people counter processor when the first connector is connected to the second connector.

Abstract: A fluid dispenser includes a dispenser housing, a container for holding a foamable liquid, a foam pump, an outlet in fluid communication with the foam pump, and a vacuum actuated suck-back mechanism in fluid communication with the foam pump and the outlet. The foam pump has a liquid pump portion and an air pump portion. The vacuum actuated suck-back mechanism includes a chamber and a movable member. The chamber has a vacuum port that is in fluid communication with the air pump portion of the foam pump, and a suck-back port that is in fluid communication with the outlet. The movable member of the vacuum actuated suck-back mechanism moves under vacuum pressure to reduce the volume of the chamber. The volume of the chamber increases upon removal of the vacuum pressure.
