Title: The Innovative Contributions of Yongping Xia
Introduction
Yongping Xia is a notable inventor based in Torrance, California, with a remarkable portfolio of 15 patents. His work primarily focuses on advancements in telemetry devices and electronic detection systems, showcasing his commitment to innovation in technology.
Latest Patents
One of his latest patents is an apparatus and method for an inbound telemetry device to sense telephone line status. This telephone-based automatic meter reading (AMR) system includes a telemetry device that allows a host computer to collect meter readings remotely. The design ensures that the telemetry device does not interfere with customer usage of other telephone devices on the line. It achieves this by sensing both the static and dynamic off-hook status of the telephone line. The telemetry device is prevented from using the telephone line whenever a telephone device is determined to be off-hook. Isolation between the telephone line and the meters is ensured using a transformer and optocouplers.
Another significant patent by Yongping Xia is an apparatus and method for remotely detecting a magnetic ballast. This portable electronic device indicates whether a ballast driving a fluorescent lamp is of the magnetic type. It comprises a power supply, a light sensor, and a microcontroller that determines the presence of a magnetic ballast based on the flicker frequency of the emitted light. The microcontroller conserves power by remaining in a "sleep" mode until activated by a user.
