  • Patent number: 8540937
    Abstract: A system and/or method formulates a chemical solution using both volumetric and weight based measurements of components of the chemical solution. The components of the chemical solution include water and at least one other component, which may take any form, such as, without limitation, liquid, solid, powder or gaseous form. Formulation of the chemical solution is administered by combining water with the one or more other components at an output port, from which this combination is dispensed to a solution storage tank. In response to a user's request to formulate a specified amount of the chemical solution, the volume of water provided to the output port is monitored by a flow meter and the weight of the other component(s) provided to the output port is monitored by one or more load cells. Based on such monitoring, appropriate amounts of water and the other component(s) are combined together to formulate the specified amount of the chemical solution in the solution storage tank.

  • Publication number: 20080029545
    Abstract: The invention generally relates to a foot activated dispenser and more particularly to a foot activated dispenser for dispensing a liquid product such as a skin care product (i.e. hand soap, hand sanitizer, surgical scrub, lotion, etc.). More specifically, the foot activated dispenser includes a bladder connected to tubing that is connected to a piston pump. The piston pump is located within a shroud that is removably attached to a wall bracket. The wall bracket includes a bottle retainer for holding a bottle having a pump.
