Patent number: 9327283Abstract: A device and a method for analyzing an analyte in a liquid sample are provided. The device comprises a detecting chamber included in a detection device for containing a detecting element; a liquid sample transferring chamber; and a film with small pores disposed between the detecting chamber and liquid sample transferring chamber. When the detection device is inserted into a liquid sample collecting chamber, the liquid sample in the collecting chamber enters the liquid sample transferring chamber but can not enter the detecting chamber via the film with small pores. When a piston is inserted into the liquid sample transferring chamber, the piston forces a part of liquid sample in the liquid sample transferring chamber to enter the detecting chamber via the film with small pores. Using the device and the method can determine an analyte in a sample quantitatively and can complete the detection in one step.Type: GrantFiled: July 9, 2010Date of Patent: May 3, 2016Assignee: Alere Switzerland GmbHInventors: Wei Liu, Andrew P. Phelan, Zhong-Qi Jin, Ying-An Zhan, Shuang Yu, Fu-Qiang Huang, Li Wang, Yin-Fei Wu, Jian Zou

Publication number: 20160028563Abstract: A method and system for impairment shifting is disclosed and may include receiving one or more radio frequency (RF) analog television signals in a receiver of a communication device, downconverting the received one or more received RF analog television signals to baseband frequencies, synchronizing the receiver to the one or more received RF analog television signals, and adjusting a frequency of one or more local oscillators in the receiver to configure in-phase/quadrature (I/Q) mismatch of a picture carrier signal to fall near a sound carrier signal in the received RF analog television signals. The frequency of the one or more local oscillators may be adjusted to configure a DC offset impairment to fall between luminance and chrominance harmonics at baseband in the analog television signals. I/Q imbalanced impairments may be configured with about 300 kHz separation from the sound carrier signal.Type: ApplicationFiled: September 30, 2015Publication date: January 28, 2016Inventors: Chengzhi Zhou, Shuang Yu

Publication number: 20150310437Abstract: A method and apparatus for avoiding a transaction rollback is provided. The method includes, at a predetermined checkpoint in a currently executing business process, determining the current service, and determining at least one service in subsequent processes of the checkpoint. The status of at least one unavailable service in the at least one service included in the subsequent processes of the checkpoint is queried. Whether the transaction can be fulfilled is determined, based on the at least one unavailable service. The execution of the transaction is stopped in response to a judgment that the transaction cannot be fulfilled.Type: ApplicationFiled: April 2, 2015Publication date: October 29, 2015Inventors: Jiu Z. Han, Qi N. Li, Yi X. Song, Shuang Yu

Publication number: 20150309836Abstract: A method and apparatus for avoiding a transaction rollback is provided. The method includes determining, by a service status check unit, whether at least one available path exists through a logic flow during an execution of a transaction. The service status check unit forecasts a successful logic flow completion on the determining the existence of at least one available path through the logic flow. The transaction is terminated, based on there being no available path through the logic flow.Type: ApplicationFiled: April 28, 2015Publication date: October 29, 2015Inventors: Jiu Z. Han, Qi N.

Patent number: 9160390Abstract: Methods and systems for impairment shifting may comprise receiving radio frequency (RF) signals in a receiver, downconverting the signals to baseband frequencies, and synchronizing the receiver to received signals. The frequency of a local oscillator (LO) may be adjusted to shift residual impairments to fall between desired baseband signals where they are least visible. The received RF signals may comprise analog, satellite, or cable, television signals. The LO frequency may be adjusted to configure the DC offset impairments to fall between luminance and chrominance harmonics. The LO frequency may be adjusted to configure I/Q imbalanced impairments from residual in-phase and quadrature mismatch of a picture carrier signal to fall about 300 kHz from a sound carrier signal in the analog television signals. The LO frequency may be adjusted to configure the I/Q imbalanced impairments from residual I/Q mismatch of a sound carrier signal to fall between luminance and chrominance harmonics.Type: GrantFiled: February 13, 2012Date of Patent: October 13, 2015Assignee: Maxlinear, Inc.Inventors: Chengzhi Zhou, Shuang Yu

Publication number: 20150018180Abstract: An auto tools change with space allowance for tool rejection of spindle includes an arm seat, an arm shaft, a tools change arm, a flat cam, and a driving arm, while the flat cam has a driving groove for driving the driving arm to swing and thus facilitates the tool clamping and tool unclamping. Therein, the driving arm has a tool clamping section having an allowance groove, a first transition section, a tool unclamping section, and a second transition section. Therefore, a larger width of the allowance groove is provided on the driving groove, thereby offering a sliding space for the tools change arm. Thus, a space allowance is produced during tool pushing process, thereby not only preventing the main shaft and the tool from being damaged, but also preventing the tools change arm from deformation.Type: ApplicationFiled: June 27, 2014Publication date: January 15, 2015Inventors: SHUANG-SHU LI, SHUANG-YU LI

The static I/Q calibration block is configured to substantially eliminate mismatches between in-phase and quadrature components of a portion of the spectrum having associated I/Q mismatches that are relatively frequency-independent. The correlation/integration block is configured to substantially eliminate mismatches between the in-phase and quadrature components of portions of the spectrum having associated I/Q mismatches that are relatively frequency-dependent in accordance with a pair of signals generated by the static I/C calibration block.Type: GrantFiled: September 29, 2008Date of Patent: March 12, 2013Assignee: Maxlinear, Inc.Inventors: Curtis Ling, Shuang Yu

Publication number: 20110096864Abstract: A device includes an analog front end for receiving a radio frequency (RF) signal. The analog front end contains a local oscillator that is tuned to a local oscillation frequency for down-converting the received RF signal to a first intermediate frequency (IF) signal. An analog-to-digital converter module converts the first IF signal to a digital baseband signal. The device also includes a digital processing unit for processing the baseband signal. The digital processing unit generates multiple clock signals from a reference oscillator having digitally adjustable reference frequency. The reference frequency and the multiple clock signals may interfere with the local oscillator and generate several frequency spurs that may fall within the bandwidth of the received RF signal. In a preferred embodiment, the digital processing unit adjusts the reference frequency by a certain amount so that the spurs do not fall within the RF signal bandwidth.Type: ApplicationFiled: October 27, 2010Publication date: April 28, 2011Applicant: MaxLinear, Inc.Inventor: Shuang Yu
