Publication number: 20190115874Abstract: A difference amplifier circuit can be used to amplify a differential input signal representative of a current flowing through a current sensing element, such as a resistor. In certain applications, a common mode voltage established at an input of the difference amplifier circuit can be greater in magnitude than a supply voltage provided to the difference amplifier circuit. A component of the differential input signal, such as one polarity of the differential signal, can be used to power the difference amplifier circuit. Such powering of the difference amplifier by the component of the differential input signal can be performed selectively, such as when a magnitude of the common mode voltage exceeds the supply voltage or another specified threshold. In this manner, a common mode input voltage capability can be greater in magnitude than a magnitude of a supply input voltage provided to an integrated circuit including the difference amplifier circuit.Type: ApplicationFiled: October 16, 2017Publication date: April 18, 2019Inventor: Quan Wan

Patent number: 10263706Abstract: A controller area network (CAN) comprising a plurality of CAN nodes that communicate via a CAN bus that comprises a fiber optical network. The fiber optical network uses a single fiber and a single wavelength for transmit and receive, and comprises a passive reflective optical star. The reflective optical star comprises an optical mixing rod having a mirror at one end. The other end of the reflective optical star is optically coupled to the transmitters and receivers of a plurality of optical-electrical media converters by way of respective high-isolation optical Y-couplers. Each CAN node produces electrical signals (in accordance with the CAN message-based protocol) which are converted into optical pulses that are broadcast to the fiber optical network. Those optical pulses are then reflected back to all CAN nodes by the reflective optical star.Type: GrantFiled: April 18, 2017Date of Patent: April 16, 2019Assignee: The Boeing CompanyInventors: Tuong K.

Patent number: 10263659Abstract: Embodiments of the present invention provide an apparatus and a method for determining a transmission direction of a secondary carrier. A reference carrier of a first secondary carrier is obtained according to network configuration information, and a transmission direction of a subframe on the first secondary carrier is determined according to a transmission direction of a subframe on the reference carrier, so that data transmission directions of the reference carrier and the first secondary carrier are the same at a same moment. A transmission direction of data of the subframes on the first secondary carrier transmitted in a frequency band adjacent to a frequency band of the reference carrier is determined by using the reference carrier, thereby avoiding interference occurring when the adjacent frequency bands simultaneously transmit data of different directions.Type: GrantFiled: November 22, 2016Date of Patent: April 16, 2019Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Bingzhao Li, Wei Quan, Xiaodong Yang, Jian Zhang, Zhenxing Hu

Publication number: 20190107944Abstract: Implementations described herein provide a multifinger keyboard that is generated based on detected input. Each key of the multifinger keyboard includes multiple input zones, which are positioned and dimensioned to correlate with a present orientation of a user's fingers. The multifinger keyboard is automatically regenerated to account for drift and other changes in position of a user's hand relative to the keyboard, thereby providing reliable targeting without requiring physical homing indicators. Each input zone may be associated with different output values, such that applying different input types to a single input zone results in different outputs. Potential outputs are determined based on concurrent inputs received at the multifinger keyboard, from which a final output is generated.Type: ApplicationFiled: October 6, 2017Publication date: April 11, 2019Applicant: Microsoft Technology Licensing, LLCInventors: Andrew Stuart GLASS, Ricardo Arturo ESPINOZA REYES, Raymond QUAN, Sophors KHUT, Christian KLEIN

Patent number: 10255385Abstract: Model optimization approaches based on spectral sensitivity is described. For example, a method includes determining a first model of a structure. The first model is based on a first set of parameters. A set of spectral sensitivity variations data is determined for the structure. Spectral sensitivity is determined by derivatives of the spectra with respect to the first set of parameters. The first model of the structure is modified to provide a second model of the structure based on the set of spectral sensitivity variations data. The second model of the structure is based on a second set of parameters different from the first set of parameters. A simulated spectrum derived from the second model of the structure is then provided.Type: GrantFiled: February 28, 2013Date of Patent: April 9, 2019Assignee: KLA-TENCOR CORPORATIONInventors: Stilian Ivanov Pandev, Thaddeus Gerard Dziura, Meng-Fu Shih, Lie-Quan Lee
