Latest Patents

One of Ryan's latest patents is for an "Asynchronous communications network." This invention describes a Local Area Network that connects multiple stations through a transmission line. Each station is equipped with a transmitter and a receiver. The transmitter generates a sequence of information signals, with individual message portions separated by flag signals. Each message portion contains a predetermined number of symbols. The receiver processes these message portions by analyzing the content of each section, which is divided into equal parts. The receiver includes various components such as stores, a detector, a signal-divider, and a unit that determines a representative value.

Another significant patent by Ryan involves "Arrangements for constructing representations of parts of bodies." This invention pertains to CT scanners, where signals representing radiation attenuation along beam paths through a patient are processed using a convolution technique. This technique provides radiation absorption values for a matrix of elements in a specified region of interest. The beams are distributed in a fan shape from a focus, and the convolution can be applied effectively by preweighting the signals for all beams based on the angular position of the beam in the fan. This approach simplifies the scaling factor that needs to be applied for each matrix element.
