  • Patent number: 11147843
    Abstract: The present invention provides a method of preventing or treating obesity by administering the probiotic bacterium of a novel Parabacteroides goldsteinii strain to the subject in need. The novel Parabacteroides goldsteinii strain is derived from the gastrointestinal tract of an individual and has better aero-tolerance and better acid-tolerance therefore it has better environmental tolerance to adapt to different living environments. The novel Parabacteroides goldsteinii strain not only can effectively prevent the weight gain of the individual, but also can effectively slow down the weight gain of the obese individual; therefore, the novel Parabacteroides goldsteinii strain of the present invention can be used for preparing a pharmaceutical composition for prevention and/or treating obesity.

  • Publication number: 20210320187
    Abstract: A method for fabricating a semiconductor device includes the steps of: providing a substrate having a NMOS region and a PMOS region; forming a first gate structure on the NMOS region and a second gate structure on the PMOS region; forming a seal layer on the first gate structure and the second gate structure; forming a first lightly doped drain (LDD) adjacent to the first gate structure; forming a second LDD adjacent to the second gate structure; and performing a soak anneal process to boost an oxygen concentration of the seal layer for reaching a saturation level.

  • Patent number: 11145733
    Abstract: The present invention discloses a method for forming a semiconductor device with a reduced silicon horn structure. After a pad nitride layer is removed from a substrate, a hard mask layer is conformally deposited over the substrate. The hard mask layer is then etched and trimmed to completely remove a portion of the hard mask layer from an active area and a portion of the hard mask layer from an oblique sidewall of a protruding portion of a trench isolation region around the active area. The active area is then etched to form a recessed region. A gate dielectric layer is formed in the recessed region and a gate electrode layer is formed on the gate dielectric layer.

  • Patent number: 11140319
    Abstract: An eye-tracking module includes a power management module, a sensing module and a processor. The power management module is configured to supply power according to a power control signal for operating the eye-tracking module in a corresponding mode, and provide a power status signal associated its power supplying status. The sensing module includes at least one image sensor configured to capture an eye image of a user at a sampling rate. The processor is configured to acquire eye characteristics of the user, the eye-movement information of the user, or vision information including user gaze coordinates according to the eye image. The processor is also configured to adjust the sampling rate, adjust its output frequency and/or switch the operational mode of the eye-tracking module according to the power status signal.

  • Publication number: 20210216092
    Abstract: A low-dropout regulator (LDO) capable of providing high power-supply rejection ratio (PSRR) and good reverse isolation. The LDO may include a core circuitry and a reverse isolation circuitry. The core circuitry may include a PSRR circuitry coupled to an output node and configured to provide high PSRR at the output node. The reverse isolation circuitry may be configured to provide good reverse isolation at the output node by, for example, providing current in response to ripples at the output node. The reverse isolation circuitry may be configured with bandwidth higher than that of the core circuitry such that it can provide fast transient response. The reverse isolation circuitry may be configurable and/or reconfigurable for a desirable reverse isolation performance. The reverse isolation circuitry may be configurable and/or reconfigurable to trade off between power consumed by the reverse isolation circuitry and a leakage current flowing through the core circuitry.
