Title: The Innovations of Adolf J. Giger
Introduction
Adolf J. Giger is a notable inventor based in Boxford, MA (US). He has made significant contributions to the field of wireless communication, holding a total of 6 patents. His work has paved the way for advancements in modem technology and data transmission.
Latest Patents
One of Giger's latest patents is a wireless modem that includes a base unit for transmitting a data signal. This modem features a communication card that receives the data signal from the base unit over a wireless medium and performs echo canceling on the data signal. The base unit is in communication with a telephone line and receives an original signal from the telephone line. It generates an RF modulated signal based on the original signal and includes a transmitter for transmitting the data signal. Circuitry in the base unit receives the original signal from the telephone line and generates a combined data signal from the original signal and echo signals, maintaining a peak voltage of the combined signal within the linear amplification region of the transmitter.
Another significant patent involves circuitry to establish a wireless communication link. This circuitry transmits an analog data signal over a wireless communication link and includes a receiver that receives a data signal. An automatic gain control circuit keeps the peak amplitude of the data signal substantially constant and within a predetermined linear amplification range. The transmitter, having this predetermined linear amplification range, receives the data signal from the automatic gain control circuit and outputs the data signal.
