Latest Patents

One of his latest patents focuses on fire alarm systems. This invention relates to a strobe notification appliance that includes a boost circuit connected to an input voltage, an energy storage circuit, and a drive circuit that generates a drive current. The LED circuit features at least one LED element, while a first sampling circuit collects the overall voltage drop of all LED elements. The control circuit is designed to adjust the drive circuit to supply a working current during an alarming stage and a detection current during a detection stage. The detection current is lower than the working current, ensuring that the light energy produced during the detection stage is less intense than during the alarming stage. This innovative approach allows the control circuit to determine the normal operation of the LED circuit based on the collected voltage drop.

Another patent by Liang involves a method and apparatus for structure analysis of a circuit design. In this exemplary embodiment, a functional specification of a circuit design is received, defined based on behavior layer abstraction. Design codes for the circuit design are also received, with each code defined based on the same abstraction. The design codes are then searched for those that satisfy the functional specification, allowing for the recognition of compliant design codes.
