Latest Patents
One of Liang's latest patents is a test fixture and method using the DTR pins and CTS pins of RS-232 connectors for automatically turning on computers. This test fixture includes a first RS-232 connector and a second RS-232 connector. The data terminal ready (DTR) pin of the first RS-232 connector is connected to the DTR pin of the second RS-232 connector, while the clear to send (CTS) pin of the first RS-232 connector is connected to the CTS pin of the second RS-232 connector. The DTR pins are further connected to a power pin of each of the test computers. The test fixture sets a high level voltage for the connected DTR pins and a low level voltage for the connected CTS pins according to the commands of turning on the test computers sent by the control computer. This innovative design allows for efficient automation in powering on test computers.
Another notable patent is a fan system with a switching module connecting a PWM device and fan. This switching module connects a Pulse Width Modulation (PWM) device to multiple fans under test. It includes a printed circuit board (PCB) and several groups of signal connectors arranged on the PCB. Each group consists of a first port, a second port, and a third port interconnected with each other. The first port connects to a testing port of an external PWM device, the second port connects to a corresponding fan, and the third port connects to an interface of a server motherboard. This invention enhances the testing capabilities of fan systems.
