Title: Absar Naseer: Innovator in Communication Technology
Introduction
Absar Naseer is a notable inventor based in Mesa, AZ (US), recognized for his contributions to communication technology. He holds a total of 4 patents, showcasing his innovative spirit and technical expertise in the field.
Latest Patents
Among his latest patents is a circuit designed to detect the hook status and ringing at the customer premises equipment (CPE) end. This invention provides a method for indicating the status of a telephone line, whether it is on-hook, ringing, or off-hook. The circuit utilizes a transconductance amplifier to convert the voltage difference across a two-wire telephone line into a proportional current. This current is then transformed into a single-ended ground-referenced voltage by a current to voltage converter. The system includes a voltage-controlled switch that indicates the on-hook status when the voltage exceeds a predefined value, while the off-hook status is indicated when it falls below that value. Additionally, the ringing status is detected through a repetitive cycle of the voltage-controlled switch.
Another significant patent is the enhanced subscriber line interface circuit, which is designed for digital switching systems. This circuit includes a line configuration and protection circuit connected to the subscriber line and a thick-film hybrid module. The hybrid module features a high voltage interface circuit that powers the subscriber line, converts analog voice signals into differential voltage signals, and detects the status of the subscriber line. The PCM conversion circuit then transforms these differential signals into PCM digital signals, facilitating efficient communication.
