A system and method adapted to have high sensitivity to the formation of biofilm by mixed community bacteria in fluids. The system enhances corrosion imbalance by differentiating conditions between metal sensor elements immersed in the liquid being monitored. The liquid may be diverted to and flowed through a sample chamber where adjacent sensor elements may reside in different flow velocity or temperature regions. The differentiated conditions allow for different film formation on one of the sensor elements relative to the other, and also more quickly than in the main system from which the sampled liquid has been diverted. The differentiated formation allows the use of measurement of polarization current between the metal sensors to produce data with superior resolution relative to prior methods. The speed of film formation promoted by the differentiated conditions allows for determination of risk of film formation in the main system prior to that film's formation in the main system.

A chemical dispensing system is provided having a micro-controller and at least one expansion module. The expansion module includes an expansion module interface. The expansion module is in communication with the micro-controller via the expansion module interface. The at least one expansion module expands capabilities of the chemical dispensing system beyond a base operation of the device.

A system and method is disclosed for indicating satisfactory times for titrating a chemical solution, e.g., cleaning product, used by a utility device to clean and/or sanitize various types of articles. The utility device is described in an exemplary embodiment as being a warewashing machine that applies the chemical solution to articles provided to the machine on racks. The chemical solution is formed in a solution tank from a combination of at least one chemical product and at least one rinse agent. Whereas the chemical product is described as a detergent, the rinse agent is described as water. Over a time period including multiple wash cycles, the chemical product and the rinse agent are added to the solution tank, thereby changing conductivity of the chemical solution. The present invention senses various types of information associated with the formation of the chemical solution and applies one or more test conditions to the sensed information to determine satisfactory time periods for measuring concentration of the chemical product relative to the chemical solution. Indications of the occurrence of these satisfactory times are presented on a display module in a manner visible to field persons responsible for titrating the chemical solution.

A method and system for switching the dispensing of a first solution from a first vessel to dispensing a second solution from a second vessel when a parameter of the first solution crosses a threshold is described. In one embodiment, a fluid dispensing apparatus includes a first vessel and a second vessel. The first vessel includes an output conduit adapted to dispense the first solution from the first vessel into a fluid receiving region. The second vessel includes an output conduit adapted to dispense the second solution from the second vessel into the fluid receiving region. The apparatus includes a first sensor positioned to measure a parameter of the first solution before the first fluid enters the fluid receiving region. The apparatus also includes a second sensor positioned to measure a parameter of the second solution before the second solution enters the fluid receiving region.

Embodiments of the present invention are directed to forming a seal around cables passing through an opening of a sealed enclosure in an efficient and cost-effective manner. In one embodiment, a cable sealing apparatus has a body including a plurality of grooves and a hinge. The body is foldable around the hinge to form a plurality of cable apertures from pairs of the grooves in a folded position. The body has a resilient material to form a seal around each cable disposed in a corresponding cable aperture upon being compressed by a force moving the body to the folded position. In another embodiment, a cable sealing apparatus has a body including a plurality of cable apertures each having a length. The body has a plurality of longitudinal slits each extending along the length of one of the cable apertures and disposed between the cable aperture and an external surface of the body. Each longitudinal slit is configured to be openable to receive a cable from the external surface of the body through the longitudinal slit into the cable aperture. The body has a resilient material to form a seal around each cable disposed in a corresponding cable aperture upon being compressed by a force transverse to a corresponding longitudinal slit.

A mounting method and a mounting apparatus to enable the level mounting of a first article to a second article. In accordance with one aspect of the present invention, an apparatus for mounting a first article to a second article to permit the level mounting of the first article comprises a bracket for fixed attachment to the second article, the bracket configured to receive the first article. The bracket has a level built into it, such that the bracket is installed such that the first article when mounted to said bracket is level.

A dispenser for dispensing and a method of dispensing an ingredient for a machine. An ingredient feed mechanism dispenses the ingredient to the machine. A controller is capable of controlling an amount of the ingredient delivered to the machine by varying an amount of time the ingredient feed mechanism is active. The controller has a demand mode which varies the amount of time the ingredient feed mechanism is active as a function of a parameter obtained from the machine. The controller compares the amount of time the ingredient feed mechanism is active with a reference value and switches to a timed mode if the amount of time deviates from the reference value. The controller may have an initial training mode which measures the amount of time the ingredient feed mechanism is active establishes the reference value based upon the amount of time the ingredient feed mechanism is active.

A marked card reader having a lensless optical detection system with fixed angle illumination and detection, the sensitivity of which is independent of the frequency response associated therewith. The optical detection system includes a radiation source to produce radiation and a radiation detector. A target plane is positioned so that the radiation source directs radiation toward the target plane. The detection source is positioned to sense radiation reflected from the target plane. An optically opaque body is positioned between the optical detector and the radiation source to prevent incident radiation from be sensed by the optical detector.

The present invention relates to dispensing chemicals from a multiplexed group of chemicals and delivering the chemicals to a multiplexed set of industrial washers. An input multiplexer operatively couples a selected system input tube to a chemical pump, thereby permitting a selected liquid chemical to be pumped from a chemical container through the chemical delivery system to a selected washer.

Improved timing circuits (205), charge dispensing circuits (213,215), and methods and systems (100) for operation of warewashing equipment. According to one aspect of the invention the system operates on both door and conveyor types of machines. The system dispenses both an initial charge amount and a dose amount during normal operations. In door types of systems, only a single power/signal connection (109) needs to be made to the dispensing system; in one embodiment the warewash rinse power connection. Further, the system can dispense detergent at an interval of greater than once per cycle or operation.
