  • Patent number: 7083823
    Abstract: An apparatus for monitoring an operation of a fluid dispensing gun dispensing a pattern of fluid onto a substrate moving with respect to the dispensing gun. The dispensing gun changes operating states in response to transition signals. A sensor is disposed adjacent the substrate and provides feedback signals in response to detecting edges of the fluid dispensed onto the substrate. A diagnostic monitor is responsive to the transition and feedback signals and automatically measures delays between occurrences of the transition signals and detecting corresponding edges of the fluid deposited onto the substrate resulting from the transition signals. The delays are measured by correlating the feedback signals to the transition signals. A method for measuring the delays is also described and claimed.

  • Patent number: 6841129
    Abstract: A liquid dispensing and/or aspirating device to be operated manually repeatedly, having a controlling device, a motor drive, control electronics, a manually actuatable actuating element, and a programming element, where the quantity of liquid which is conveyed by motor on actuation of the actuating element is adjusted in the control electronics by the programming element. A process interval (tp) for a plurality of process steps to be carried out in succession is stored in the control electronics. A first type of actuation of the actuating element triggers an individual process step, while a second type of actuation automatically results in repeated successive triggering of process steps, each in the process interval (tp). Handling of the device in practice is greatly improved by the fact that the process interval (tp) is automatically determined by the control electronics by analyzing the interval(s) occurring between the individual actuations of the actuating element.

  • Patent number: 6694916
    Abstract: A dispensing system (200) for chewable pet toys (100) contains multiple toys and dispenses them at intervals determined by one or more modes of operation. A display (220) and keypad (400) are used to enter programming data into the memory of a microprocessor (315). When the system is in operation, the display indicates progress through the program, the mode of operation whether MANUAL, RANDOM, or BMOD (behavior modification), the time elapsed, and the number of toys remaining. At various times, sounds emanate from a loudspeaker (320), vibration emanates from a vibrator (328), light emanates from a light source (325), and odor emanates from an odor generator (327). Toys are dispensed down a ramp (225), at predetermined times, or at predetermined times modified by random numbers. Predetermined dispensations permit modification of the pet's behavior (BMOD). Random variations on a predetermined schedule of dispensations (RANDOM) prevent the pet from memorizing a schedule.

  • Patent number: 6675988
    Abstract: A system for metering and dispensing single and plural component liquids and solids as described herein. The dispensing system has a microprocessor-based control system and progressive cavity pumps which provide a very accurate control of component ratios, shot sizes, flow rates and dispense durations. The system has numerous feedback components for accurately controlling the pressure, flow rates, fluid levels and amounts of fluids dispensed. Where a valved nozzle is used, the pressure in the flow system is used to control the pumps rather than the valve. Such a system may be used as a sprayer with compressed air added. Drum rams are associated with the supply drums and the progressive cavity pumps may be placed on the drum ram. Maintenance of a steady state in the system is accomplished with back and forth movement of the pump, with compensation for pressure changes. Absolute rotational position of the pump can be monitored when a set pressure is maintained, to diagnose system conditions.
