Patent number: 9109935Abstract: This invention is related to an apparatus which incorporates a microfabricated silicon mass flow sensor to measure city gas flow rate in a medium pressure range for utility industry which is dominated by conventional mechanical meters such as turbine and rotary meters. The microfabricated mass flow sensor is so called micro-electro-mechanical systems (a.k.a. MEMS) device. Due to the small feature size of micro scale for MEMS mass flow sensor, the invented apparatus includes many advantages such as low power consumption, compact package, high reliability and extended dynamic measurement range. This apparatus is also provided with a stable flow conditioning to achieve a desired dynamic range capability. Furthermore, because of the high accuracy characteristic, the apparatus in this invention could be applied for custody transfer or tariff in utility industry as well.Type: GrantFiled: October 28, 2012Date of Patent: August 18, 2015Assignee: M-Tech Instrument Corporation (holding) LimitedInventors: Xiangyou Yang, Yong Feng, Sugang Jiang, Chih-Chang Chen, Liji Huang

Publication number: 20150185747Abstract: A voltage regulator includes a feedback regulation loop and a drive transistor configured to source current to a regulated output. A transient recovery circuit is coupled to the voltage regulator circuit and includes a first transistor coupled to source current into a control terminal of the drive transistor, wherein the source current is in addition to current sourced in response to operation of the feedback regulation loop. The first transistor is selectively actuated in response to a drop in voltage at the regulated output. The transient recovery circuit further includes a second transistor coupled to sink current from the regulated output. The sink current has a first non-zero magnitude in the quiescent operating mode of the regulator circuit. In response to an increase in voltage at the regulated output, the operation of the second transistor is modified to increase the sink current to a second, greater, non-zero magnitude.Type: ApplicationFiled: November 17, 2014Publication date: July 2, 2015Applicant: STMicroelectronics (Shenzhen) R&D Co.

Publication number: 20150185754Abstract: A reference current path carries a reference current. A first transistor is coupled to the reference current path. A second transistor is also coupled to the reference current path. The first and second transistors are connected in parallel to carry the reference current. The first transistor is biased by a first voltage (which is a bandgap voltage plus a threshold voltage). The second transistor is biased by a second voltage (which is a PTAT voltage plus a threshold voltage). The first and second transistors are thus biased by voltages having different and opposite temperature coefficients with a result that the temperature coefficients of the currents flowing in the first and second transistors are opposite and the reference current accordingly has a low temperature coefficient.Type: ApplicationFiled: October 21, 2014Publication date: July 2, 2015Applicant: STMicroelectronics (Shenzhen) R&D Co.

Publication number: 20150121323Abstract: Determining a quality parameter for a verification environment for a register-transfer level hardware design language description of a hardware design. A netlist is generated from the hardware design language description. A list of hardware design outputs is generated, and logical paths in the netlist are generated based on the list of hardware design outputs. Furthermore, a modified netlist involving logical paths is generated by determining whether a gate is selected as an insertion point, and selecting a fault type, which is part of the efficiency vector for the selected gate in the netlist and inserting a mutant. Additionally, a fault simulation is performed and the quality parameter for the verification environment is determined from the fault simulation and the simulation result data.Type: ApplicationFiled: October 20, 2014Publication date: April 30, 2015Inventors: Peng Fei Gou, Bodo Hoppe, Dan Liu, Yong Feng Pan
