  • Patent number: 9974235
    Abstract: A device for harvesting mushrooms from a mushroom bed involves a robotic arm configured to interchangeably deploy one of a plurality of different suction grippers, each of the suction grippers having a suction cup having a size and shape profile appropriate for gripping a cap of a mushroom, the cap having a size and shape profile within a predetermined range. A vacuum source in fluid communication with the suction gripper supplies negative air pressure to the suction gripper for retaining a cap of the mushroom to be harvested in the suction cup. A control circuit in electronic communication with the suction gripper and the vacuum source is configured to automatically adjust the negative air pressure in the suction gripper in response to harvesting requirements during a mushroom harvesting process.
    Type: Grant

  • Patent number: 9730394
    Abstract: A method and system for controlling harvesting of mushrooms from a bed during a mushroom graze harvest operation account for both mushroom separation and stagger, thereby providing for automatic and proper selection of which mushrooms in the bed are to be harvested in a given shift.

  • Patent number: 6097117
    Abstract: A connector structure 10 is provided for powering an electric motor 19. The connector structure 10 includes a connector body 12; a low speed terminal 14 in the body; a high speed terminal 16 in the body; and a ground terminal 18 in the body. The ground terminal and the high-speed terminal are constructed and arranged to be coupled directly to the motor. The low speed terminal, the high speed terminal and the ground terminal are constructed and arranged to be coupled to a source of electrical power to power the motor. A resistive element 20 is coupled between the low speed terminal and the high-speed terminal. A shield member 26 houses the resistive element. The shield member is coupled directly to the connector body. Electrical power to the motor may be by controlled by selectively energizing the low speed terminal, the high speed terminal, or both the low speed terminal and high speed terminal so as to operate the motor at two different speeds.
