  • Patent number: 9234512
    Abstract: A compact, modular dosing pump system that is capable of microdose and macrodose volume flow rates, reduces or eliminates the need for additional flow control components such as temperature and pressure sensors, and utilizes a wider operational flow range than existing systems while maintaining the level of accuracy and precision exhibited by conventional dosing pump systems is provided. The dosing pump utilizes a pump and flow circuit, and a control system may be used to deliver a range of fluid volumes. The flow circuit utilizes a networked system of fluid paths and valves to route fluid through the dosing pump system in response to a pressure differential between fluid inlet and fluid outlet ports, while the controller monitors and controls the operation of the system.

  • Patent number: 8511196
    Abstract: A traction drive system for an articulated robotic arm. The traction drive system can include an input drive disk, a spider, an array of traction balls, a traction plate, an output drive shaft, a clamping device to load the traction balls, and an absolute rotation position sensor system. The rotation of the output drive shaft can be coupled to the rotation of the input drive disk while the traction balls are frictionally engaged to the drive disk surface and traction plate surface. The rotational connection can be decoupled when the traction balls are not frictionally engaged to the drive disk surface and traction plate surface. A rotational position sensor located in proximity to the traction drive can provide absolute rotational position feedback of the output drive shaft.

  • Publication number: 20120061418
    Abstract: A product delivery system for delivering a product from a storage area to a dispensing area, such as for use in a vending machine. The product delivery system may include a vacuum holding device, a robotic positioning system, a reel and cable system, and a controller. A feature is the provision of a picker head with a built-in vacuum generating source that may be carried by a robotically movable arm system.
