  • Patent number: 11389894
    Abstract: A method for laser keyhole welding of metal alloys is disclosed. The method independently adjusts power in a focused center beam and power in a concentric focused annular beam. At the termination of a weld, the power in the center beam is initially ramped up and then ramped down, while the power in the annular beam is ramped down. Increasing the power in the center beam enables a controlled and prolonged contraction of the keyhole and melt pool, thereby preventing undesirable cracking.

  • Patent number: 11350787
    Abstract: A device for cooking a starch-based food item is provided in which there is a drying cycle at a temperature below the gelatinization temperature and a cooking cycle at a temperature above the gelatinization temperature. The drying provides a relative weight drop by a first amount and the cooking provides a further relative weight drop. The weight is monitored during drying and cooking to provide feedback control of the duration of the drying and cooking times. The device and method make healthy food with reduced rapid digestible starch (RDS) and increased resistant starch (RS) content. In this way the glycemic index (GI) of a food item is reduced and the resistant starch is increased, which is beneficial to health especially for diabetes and obese groups.
