Patent number: 9853560Abstract: Congruent power and timing signals in a single electronic device. In an embodiment, a circuit may include just one isolation transformer operable to generate a power signal and a timing signal. On the secondary side, two branches may extract both a power signal and a clock signal for use in the circuit on the isolated secondary side. The first branch may be coupled to the transformer and operable to manipulate the signal into a power signal, such as a 5V DC signal. Likewise, the second circuit branch is operable to manipulate the signal into a clock signal, such as a 5 V signal with a frequency of 1 MHz. By extracting both a power supply signal and a clock signal from the same isolation transformer on the secondary side, valuable space may be saved on an integrated circuit device with only having a single winding for a single isolation transformer.Type: GrantFiled: June 23, 2015Date of Patent: December 26, 2017Assignees: STMICROELECTRONICS (SHENZHEN) R&D CO., LTD., STMICROELECTRONICS (CHINA) INVESTMENT CO. LTDInventors: Henry Ge, Welsin Wang, Xing Zhang

Patent number: 8638038Abstract: According to an embodiment of the present disclosure, a plurality of light-emitting diode (LED) modules in series are monitored. When an LED module is detected as failing or operating inadequately, a bypass switch removes the particular LED module from the series and the voltage provided to the series is modified. When the LED modules are detected as having too high of a temperature, the current provided to the LED modules is limited.Type: GrantFiled: November 22, 2011Date of Patent: January 28, 2014Assignees: STMicroelectronics (Shenzhen) R&D Co., Ltd., STMicroelectronics Asia Pacific PTE, Ltd.Inventors: Henry Ge, Leslie Leong

Patent number: 8590395Abstract: A flow meter for measurement of a metered fluid has a sensor element that receives a flow input of a metered fluid and outputs a flow output of the metered fluid, and a battery element. The sensor element has an inductor element and a magnetic element coupled to the inductor element. In response to movement of the magnetic element relative to the inductor element caused by a fluid pressure differential of the metered fluid, the inductive value of the inductor element changes.Type: GrantFiled: November 9, 2010Date of Patent: November 26, 2013Assignee: STMicroelectronics (Shenzhen) R&D Co., Ltd.Inventor: Henry Ge
