  • Patent number: 10102401
    Abstract: A vending machine user interface can include a first controller operatively connected to an input device capable of receiving payment or account information. The first controller can, with another device, via a second controller, or otherwise, allow secure communication of data from the input device. The first controller, in this regard, can control the communication between the input device and the other device to protect the input device from unwarranted communication from the other device. The first controller can establish a secure channel with the other device using encrypted communications. The first controller, second controller, etc. can be connected to independent printed circuit boards (PCB). Activation of sensors connected to the PCBs can cause the first and/or second controllers to erase data necessary to ascertain/decode communications from the input device, such as encryption/decryption information, or may otherwise decommission the input device or a portion thereof.

  • Patent number: 7767266
    Abstract: A method and a system for jetting droplets of viscous medium, such as solder paste, onto a substrate, such as an electronic circuit board. The volume of the droplets are adjusted by regulating the amount of viscous medium that is fed into a jetting nozzle for subsequent jetting of the viscous medium droplets therefrom. The exit velocity of the jetted droplets is adjusted or maintained substantially constant by regulating the velocity with which the viscous medium is impacted. Furthermore, the rate at which viscous medium is fed, for instance by a feed screw, into the nozzle is adjusted in order to regulate the feeding time required for feeding the viscous medium into the jetting nozzle, for instance in order to maintain a constant feeding time.

  • Patent number: 7753231
    Abstract: A beverage dispenser has a faucet with a spout, a fitting for connection to a beverage supply, and a lever operated valve. A servo motor, coupled to the lever, operates the faucet and proportionally controls the flow of the beverage. That proportional flow control manages the amount of beverage foaming. A flow sensor has a magnetic turbine within the faucet and a Hall effect element that magnetically senses turbine motion and produces a signal indicating an amount of beverage flow. A keypad enables service personnel to designate various portions of the beverage to automatically fill serving containers of different sizes. A control circuit responds to activation of the keypad and to the flow sensor by operating the servo motor to dispense the related quantity of the beverage.

  • Patent number: 7681759
    Abstract: Fluid-dispensing apparatus include a fluid-dispensing needle. A gas discharge member is positioned proximate a dispensing end of the needle that is configured to direct a gas towards a fluid tear-off position below the dispensing end of the needle. A controller controls discharge of the gas by the gas discharge member to control dispensing of fluid from the needle. The dispensing control may control an amount of fluid dispensed from the needle and/or tailing off of fluid dispensed from the needle. The amount of fluid dispensed from the needle may be a microliter range volume of a viscous fluid.

  • Patent number: 7669734
    Abstract: A dosing system to dispense a predetermined quantity of a fluid medium comprises a digital signal processor control having an interface to emit a start signal and a stop signal and an interface to measure a sensor signal. A dispenser is provided that is triggered by the start signal and the stop signal and, in the interval between the two signals, dispenses a specific quantity of fluid, as well as a sensor unit which, triggered by the start signal, continuously measures the flow rate of the fluid fed to the dispenser and emits a sensor signal as a function of this flow rate. The digital signal processor control measures the sensor signal, determines the quantity of fluid dispensed by the dispenser from this signal and sends a stop signal to the dispenser when the quantity of fluid dispensed by the dispenser corresponds to the predetermined quantity of fluid.

  • Publication number: 20090314980
    Abstract: A valve comprises a valve cartridge, a valve stem and a valve seal. The valve cartridge comprises a generally cylindrical cartridge body, a bore extending longitudinally through the cartridge body, and an outlet passage and intermittent inlet passages extending through a side wall of the cartridge body to intersect the bore. The valve stem comprises an elongate body configured to slide within the bore, and a neck and a seal channel circumscribing the elongate body. The valve seal is seated within the seal channel. The valve stem slides within the bore to move the seal channel past the inlet passages. Portions of the cartridge body between the inlet passages retain the valve seal within the valve channel until the inlet passages are open to the neck. In one embodiment, the inlet passages form a crenelated edge. In another embodiment, the inlet passages form a ported end.

  • Publication number: 20090314797
    Abstract: A hand-held flow metering device for dispensing a pressurized fluid comprises a valve, a flow meter, a trigger lever, a trigger release mechanism and meter electronics. The valve is connected to the pressurized fluid to regulate flow of the pressurized fluid through the device. The flow meter is disposed within the flow of pressurized fluid to measure volumetric flow of the pressurized fluid. The trigger lever is configured to be manually displaced to mechanically open the valve. The trigger release mechanism is connected to the trigger lever and is selectively actuated to mechanically prevent the trigger lever from opening the valve when the trigger lever is displaced. The meter electronics is connected to the flow meter and the trigger release mechanism to actuate the trigger release mechanism based on output of the flow meter.
