    Abstract: A dispenser with an automatic pump output detection system includes a controller that controls the operation of an actuator that moves in a first and second direction along a path. A limit stop is adjustably disposed along the path, such that when the actuator moves in the first direction, it engages the limit stop and the pump. Upon engaging the limit stop, the controller reverses the movement of the actuator so that it moves in the second direction. As such, the specific discrete position of the limit stop determines the amount of material dispensed from the pump.

  • Patent number: 8083498
    Abstract: Embodiments of the systems and methods disclosed herein utilize a brushless DC motor (BLDCM) to drive a single-stage or a multi-stage pump in a pumping system for real time, smooth motion, and extremely precise and repeatable position control over fluid movements and dispense amounts, useful in semiconductor manufacturing. The BLDCM may employ a position sensor for real time position feedback to a processor executing a custom field-oriented control scheme. Embodiments of the invention can reduce heat generation without undesirably compromising the precise position control of the dispense pump by increasing and decreasing, via a custom control scheme, the operating frequency of the BLDCM according to the criticality of the underlying function(s). The control scheme can run the BLDCM at very low speeds while maintaining a constant velocity, which enables the pumping system to operate in a wide range of speeds with minimal variation, substantially increasing dispense performance and operation capabilities.

  • Patent number: 8074836
    Abstract: A dispensing system is disclosed which utilizes an electronically powered key device and/or identification code associated with a refill container to preclude the need for mechanical keys. The system utilizes a near field frequency response to determine whether a refill container is compatible with a dispensing system. In particular, the refill container is provided with a coil terminated by one of a number of capacitors. The container is received in a housing that provides a pair of coils that are in a spatial relationship with the installed refill container's coil. By energizing one of the housing's coils, the other coil detects a unique electronic signature generated by the container's coil. If the signature is acceptable, the dispensing system is allowed to dispense a quantity of material. The system also provides a unique latching mechanism to retain the container and ensure positioning of all the coils.

  • Patent number: 7934622
    Abstract: An improved system and method for dispensing dehydrated culture media (DCM) powder into containers for preparation as a culture media. The manual and automated systems and methods operate to dispense DCM powder, as well as liquid, into vessels or media preparation instruments in a manner to avoid DCM dust inhalation by persons in the surrounding area and contamination of equipment and surfaces in the surrounding area. The system can further comprise a carousel arrangement that permits dispensing of DCM powder from multiple containers at multiple volumes and rates. In addition, the containers have a particular configuration for use with the system and method, such as the carousel arrangement, to avoid errors, promote repeatability and eliminate dusting. The containers can also include a device, such as an auger, to facilitated measured dispensing of the DCM powder automatically or manually into a flask, automated media sterilizers or other instruments.

  • Patent number: 7918367
    Abstract: A system for monitoring and controlling the delivery of CO2 from a bulk storage tank to at least one gas-driven pump is disclosed. By monitoring certain conditions, the flow of CO2 can be quickly and easily terminated if necessary, thereby reducing or eliminating undesirable consequences of CO2 gas flow in abnormal operational scenarios. The invention is particularly well suited for deployment in conjunction with beverage dispensing machines and can be configured to shut down the flow of CO2 if a drop in pressure occurs due to a leak in the system or if a syrup delivery system runs out of product.

  • Publication number: 20110062182
    Abstract: A dispenser with an automatic pump output detection system provides a pump with an adjustable output. The pump is coupled to a current sensor that generates an operating profile based on the electrical current consumed during each dispensement of material by the pump. A controller that includes one or more previously-stored reference profiles that correspond to discrete pump output amount values that are compared with each generated operating profile, whereby the discrete pump output amounts associated with the matching reference profile is used to compute various usage data associated with the operation of the dispenser.

  • Patent number: 7905373
    Abstract: A method and computer program product for defining a PWM drive signal having a defined voltage potential. The PWM drive signal has a plurality of “on” portions and a plurality of “off” portions that define a first duty cycle for regulating, at least in part, a flow rate of a pump assembly. At least a portion of the “on” portions of the PWM drive signal are pulse width modulated to define a second duty cycle for the at least a portion of the “on” portions of the PWM drive signal. The second duty cycle regulates, at least in part, the percentage of the defined voltage potential applied to the pump assembly.

  • Patent number: 7886943
    Abstract: A portable drywall joint compound pump workstation has a joint compound supply reservoir with an open top and closed bottom removably attached to a wheeled framework. The workstation further has a pump assembly including a pump control removably connected to the framework for pumping joint compound from the supply reservoir to a workstation outlet extending from the pump control. The pump assembly includes a high pressure cylinder connected to a valve and quick coupling arrangement which, in turn, is in communication with the supply reservoir through the bottom end thereof. A discharge line extends between the high pressure cylinder and the pump control for feeding joint compound from the supply reservoir to the pump control. A first discharge port is provided on the pump control for continuously feeding a variety of drywall finishing tools. A second discharge port is provided on the pump control for supplying wash down water to clean tools or act as a source of high pressure fluid.

  • Patent number: 7854348
    Abstract: A device for dispensing a viscid material includes a supporting body constructed by a carriage. A ball screw is installed within the supporting body. A rod piston is mounted on one end of the ball screw. A transmission module is mounted on a nut of the ball screw. The transmission module is engaged with an actuator controlled by a control circuit device. The control circuit device, which includes a switch and a circuit board, etc, controls the positive and negative rotations and the stop operation of the actuator. A trigger is set up on one side of the supporting body. When the trigger is pressed, the actuator is driven to rotate in the positive direction to drive the ball screw to move forwardly in a stable way. While the trigger is released, a sensor is activated to drive the actuator to rotate in the negative direction.
