Title: Sing Ngee Yeo: Innovator in Asynchronous Data Transfer Systems
Introduction
Sing Ngee Yeo is a notable inventor based in Stratford, CT (US). He has made significant contributions to the field of data transfer systems, holding a total of 3 patents. His work focuses on enhancing the efficiency and functionality of asynchronous data transfer mechanisms.
Latest Patents
One of his latest patents is titled "Methods and apparatus for accessing full bandwidth in an asynchronous data transfer and source traffic control system." This invention allows certain bus users, such as network cards, to access both odd and even frames, while other users, like subscriber line cards, can access only odd or even frames. The apparatus supports line cards numbering up to 32 minus twice the number of network cards. An exemplary embodiment illustrates a single network card connected to an OC-12 network link and twenty asymmetric digital subscriber line cards.
Another significant patent is "Method and apparatus for implementing a backpressure mechanism in an asynchronous data transfer and source traffic control system." This invention involves detecting congestion experienced by a bus user and preventing other users from sending cells over the bus. In one embodiment, if congestion is detected for two consecutive frames, the arbiter is inhibited from granting access to any bus user for one frame. In another embodiment, if congestion is detected during any frame, all bus users are prevented from transmitting low-priority traffic until congestion is absent for four consecutive frames. An apparatus for performing these methods is also disclosed.
