Title: The Innovative Contributions of Allen Podell
Introduction
Allen Podell is a notable inventor based in Palo Alto, California, recognized for his contributions to wireless communication technologies. With a total of two patents to his name, Podell has made significant advancements in collision detection methods and microstrip transmission line structures.
Latest Patents
One of Podell's latest patents is titled "Radio Based Collision Detection for Wireless Communication System." This invention presents a collision detection method and apparatus suitable for use in wireless CSMA/CD networks and other wireless networks. The apparatus includes a detector that identifies intermodulation or other mixing products of colliding data transmissions at a network station. A signal processor indicates collisions based on the characteristics of these intermodulation products. The system can detect collisions from both the station's transmissions and those from other sources. Additionally, it can identify collisions between two transmissions received from different sources.
Another significant patent is focused on "Constant Impedance Transition Between Transmission Structures." This invention involves a microstrip transmission line structure composed of a series of connected microstrip strip sections with varying widths. These sections are arranged on an outer layer of a unitized multilayer circuit structure, forming a microstrip line. The design includes respective ground planes for each strip section, spaced between insulating layers to maintain a substantially constant impedance along the microstrip line. Conductive vias are utilized to electrically interconnect the ground planes.
