  • Patent number: 10196582
    Abstract: A method and system for extracting fluids from plant parts is provided. Plant parts are placed into a filter bag that is placed within a fluid impermeable holder, which is generally a non-stick holder such as wax paper or parchment. The fluid impermeable holder is placed into a press that is operable at an elevated temperature. The press applies pressure at a predetermined temperature for a predetermined time to the fluid impermeable holder and filter bag to compress the plant parts and squeeze or extrude the fluid from the plant parts. After a predetermined time, the press is opened and the fluid impermeable holder is removed. The filter bag, with residual plant parts, is removed from the fluid impermeable holder. The fluid impermeable holder is manipulated to collect the fluids, which manipulation may include freezing the fluids and peeling the fluids from the inner surface of the bag.

  • Patent number: 10059061
    Abstract: A system for manufacturing a composite structure includes a tool with a surface for supporting component elements of the composite structure. The surface is divided into a multi-dimensional array of thermal zones for in-process control of the temperature of a component element (e.g. resin) of the composite structure. The sensors sense a characteristic of the component element and provide sensor data, which is applied to a machine-learning algorithm configured to generate control data to achieve a defined quality goal. A controller then independently controls the thermal zones to locally heat, cool or maintain the temperature of the component element according to the control data to advance the component element or composite structure to the defined quality goal. This may be performed over a plurality of instances during which the machine-learning algorithm learns to increase advancement of the component element or composite structure to the defined quality goal.

  • Patent number: 6526878
    Abstract: A media binding device is operable to apply pressure on a plurality of media sheets, while applying heat to melt adhesive provided between the sheets of media. The media binding device may be implemented in conjunction with an image forming device, e.g., printer, facsimile machine, photocopier, etc. More specifically, the media binding device may be implemented in a position generally at an output end of the image forming device, following a collating or stacking of the printed media. The media binding device applies a predetermined amount of pressure on the plurality of media sheets. In this respect, the media binding device operates to apply a gradually increasing amount of pressure onto the media sheets until a predetermined amount of pressure is reached. The predetermined pressure is applied on the media sheets by shutting off the current flowing into a motor operating the media binding device when a predetermined current level is reached.
