  • Patent number: 10267791
    Abstract: A biological test strip with isolation structure includes a substrate having a testing portion and a measuring portion; an electrode disposed on the substrate and including an operation electrode and an auxiliary electrode, the operation electrode having a first operating end and a first reading end, the auxiliary electrode having a second operating end and a second reading end; a first flow confining member surrounding the first operating end; and a second flow confining member surrounding the first flow confining member and the second operating end, with a height of the second flow confining member larger than a height of the first flow confining member. Therefore, the flowing scope of the dropped liquid is confined, so as to fix the square measure of the dropped liquid contacting the electrode and thereby improve the analysis repeatability.

  • Publication number: 20180362510
    Abstract: This invention provides a method for enantioselective synthesis of cis-imidazolines and related structures through chiral resolution. A chiral acid is used to separate enantiomeric precursors of the cis-imidazolines from a racemic mixture by selective crystallization. Both enantiomers can be cyclized into the desired cis-imidazoline by complementary pathways. Compounds can be synthesized according to the invention with an enantiomeric excess as high as 99%. Cis-imidazolines such as Nutlin-3a prepared according to this invention may be used for treating cancer, killing senescent cells, or treating senescence-associated conditions.

  • Patent number: 10128830
    Abstract: A track and hold circuit comprises an input buffer amplifier, a unit gain amplifier module, a sampling switch, a drive triode and a sampling capacitor. The input buffer amplifier receives an input signal. In a track phase, the sampling switch is electrically connected to an emitter electrode of the drive triode; the input signal charges the sampling capacitor after being buffered by the input buffer amplifier, amplified without distortion by the unit gain amplifier module and driven by the drive triode. In a hold phase, the sampling switch is electrically connected to a base electrode of the drive triode; the base voltage of the drive triode is pulled down until the drive triode is cut off; electrical charges on the sampling capacitor are thereby held, causing the signal to be held on the sampling capacitor.

  • Publication number: 20180302358
    Abstract: Exemplary embodiments relate to techniques for presenting and targeting media in communications services. Media, such as live events, updates on a topic of interest, or digests of news sites or other content providers may be surfaced to a user in a number of ways; for example, an article view relating to the topic, a messaging view showing message threads, a media view showing interesting pieces of media, or in an active conversation based on analysis of a conversation and trending topics, such as news events. A system may suggest recipients that may be interested in discussing the content. The recipients may be presented in a ranked order based, for example, on an affinity or relationship of the recipients to a publisher of the content. Publishers may add or remove topics, and may set an end-time at which updates cease. The updates may be presented in a messaging thread.

  • Patent number: 9966967
    Abstract: A high-speed successive approximation analog-to-digital converter of two bits per cycle, includes three switches, two capacitor arrays, three comparators, an encoding circuit, a first switch array corresponding to the first capacitor array, a second switch array corresponding to the second capacitor array, a shifting register and a digital correction unit. The analog-to-digital converter, featuring doubled speed, realizes a successive approximation process without any fault when a high-bit large capacitor is unsettled. Thus no redundancy bit capacitor is required to compensate for unsettled pre-stage large capacitor. By using the encoding circuit, a thermometer code is converted into a binary code effectively, and inherent errors of comparators are reduced by the randomization of three comparators.
