With a total of two patents to his name, Lamb has focused on enhancing safety and efficiency in microwave ovens, paving the way for improved user experiences in modern kitchens.

Latest Patents

Lamb's latest patents include an energization circuit for microwave ovens and a safety interlock switch. The energization circuit employs a PTC thermistor to eliminate high transient current surges during energization and deenergization of induction elements, offering much-needed circuit protection during both the start and operation of the oven. This circuit consists of two parallel portions that energize a transformer responsible for invigorating a magnetron that generates microwave energy. With its clever use of a current-limiting thermistor and a relay-operated switch, the design minimizes high current surges while ensuring the magnetron receives the necessary power.

Additionally, Lamb's safety patent focuses on a protector switch that activates if the door interlock switch fails. This monitor switch, which is designed to close when the door opens, ensures that power is immediately cut off to the oven under unsafe conditions. By incorporating a heat-responsive electrical resistance element, this invention effectively prevents any potential short-circuit hazards, making microwave ovens safer for everyday use.
