Latest Patents

One of Langridge's notable inventions is the Digital Diversity Receiver System. This two-way paging system comprises one or more transmitters, multiple receivers, and at least one two-way personal paging unit or pager. The two-way pager is designed to receive pages from the transmitter and send response signals that are detected by the receivers. These response signals are formatted as digital packets, which include forward error correction encoding and digital symbols, each consisting of a predetermined number of bits. The receivers decode these response packets to verify their accuracy and identify the digital symbols.

Additionally, the system incorporates 'accuracy indicators' that can be associated with the detected symbols, providing an indication of the probability of accuracy. In one embodiment, referred to as the 'microdiversity receiver,' two receiver components are utilized at a single receiver site, each with a separate antenna. This design allows for the comparison of signals received at different components, enhancing the reliability of detecting and decoding pager response symbols. A central controller processes information from several receivers to determine the most likely response signal sent by a pager.
