Latest Patents
One of Johnston's latest patents is for inductive devices for printed wiring boards. These devices, including transformers, coils, and inductors, are produced from a rolled flexible circuit. The flexible circuit consists of a dielectric substrate with a circuit pattern that, when rolled, forms one or more coils, thereby defining an inductor or transformer. This design allows for easy shielding using a ground plane and can be secured with adhesives or thermoplastic bonding layers. The inductive devices are compact, surface mountable, and cost-effective, making them suitable for automated insertion onto printed wiring boards. Another significant patent is for a rolled delay line of the coplanar line type. This time delay device adjusts the arrival time of an electronic signal at a specific area in a circuit pattern. It features a coplanar flexible circuit with a serpentine signal line and a ground shield, which is tightly rolled and packaged for durability.
