Title: Innovations of John W MacConnell
Introduction
John W MacConnell is a notable inventor based in Spokane, WA (US). He has made significant contributions to the field of telecommunications and utility metering, holding a total of 7 patents. His work focuses on enhancing communication systems and improving the efficiency of utility meter readings.
Latest Patents
One of his latest patents is the "Cellular repeater watermarking system and method." This invention provides a method and system for embedding a watermark by amplitude modulating data onto signals being repeated from and/or to a cellular telephone handset. This process is designed to maintain the performance of the cellular telephone system. The exemplary cellular repeater system includes a first communication device that receives a cellular telephone signal from a handset. The signal is then amplified by a variable gain amplifier, which creates an adjusted signal. The amplification factor is controlled by a message encoder that follows a predetermined encoding scheme. The adjusted signal is subsequently transmitted to a base station by a second communication device.
Another significant patent is the "Spread spectrum meter reading system utilizing low-speed/high-power frequency hopping." This system allows for high power frequency hopping spread spectrum (HPSS) transmissions at both the encoder transmitter and repeater levels. It consists of multiple end point encoder transmitter devices connected to utility meters, which transmit high power FHSS signals containing metering data. Intermediate transceiver units receive and retransmit these signals to a base station, which aggregates the data for efficient processing. The design aims to reduce power consumption and extend the battery life of the devices.
