  • Publication number: 20250137850
    Abstract: A pair of light rays spatially-sheared with a controllable beam-shear distance is generated by a module having a beamsplitter (BS) and two mirrors. The BS splits an input light ray into first and second split light rays respectively propagated on first and second light paths. The two mirrors are respectively located at distal ends of the two light paths, and cause each split light ray to undergo a two-stage reflection, thereby generating first and second reflected light rays directed to the BS. The BS processes the two reflected light rays to generate the pair of spatially-sheared light rays. Orientations of the two mirrors in yaw angle, pitch angle, or both, are jointly adjustable to realize and control the beam-shear distance without using any birefringent crystal-based prism. The module is used to form differential interference contrast (DIC) microscopes providing variable shear distances, advantages of orientation independence, etc.

  • Patent number: 10296512
    Abstract: Aspects of the subject technology relate to systems and methods for action-based content scoring. Scores associated with a content item are determined. Each of the scores is generated by a different predictive model and associated with a respective user interaction type. A composite score for the content item is determined based on at least one of the scores. The content item is provided for display in a content stream associated with a user based on the composite score.

  • Patent number: 10250570
    Abstract: The present invention provides a separated intelligent control system comprising a WiFi intelligent controller. The WiFi intelligent controller comprises: a WiFi unit for performing network communication; a microprocessor connected with the WiFi unit for data transmission via the WiFi unit, the data comprising programs or instructions; and at least one multi-use interface. The multi-use interface comprises a plurality of pins. The plurality of pins is connected to the microprocessor. The microprocessor is used to change function of the plurality of pins of the multi-use interface via firmware. The WiFi intelligent controller can be independently and freely combined with external modules with different functions so as to achieve the desired functions of users. The combination of application is strengthened, so that users can freely combine or restructure each module at any time to be used in different appliances and situations.

  • Publication number: 20170053734
    Abstract: A transformer structure includes a winding cylinder which is a hollow tube, at least one limiting ring which is a ring sheet, multiple conductive sheets and at least one winding. The limiting ring is able to slide along the winding cylinder and to sleeve on the outside of the winding cylinder. The conductive sheets are sleeved on the outside of the winding cylinder. Two conductive sheets of the conductive sheets are attached to two end surfaces of the limiting ring while the two conductive sheets and the limiting ring form a winding space. The at least one winding is correspondingly disposed in the winding space. Thereby, the assembly of the transformer is simplified, and the winding area, as well as the voltage ratio of the transformer, is increased.

  • Patent number: 9385625
    Abstract: A RF-to-DC converter charges a battery or powers a circuit from the energy of received radio waves. The RF energy received is very small for far-field applications, so the converter is highly sensitive. Four capacitor arrays are arranged in two banks. Buffered RF signals pump bottom plates of the capacitors. A series of L-switches in each bank connect between the two capacitor arrays in that bank. Each L switch has a pre-charge switch that charges that stage's input capacitor, and a stage-transfer switch that shares charge from the input capacitor to an output capacitor for that stage. Switches in the two banks alternately pre-charge and pump, with the left bank pumping while the right bank pre-charges. Switches are transistors with substrates tied to their sources or actively driven by substrate control signals. One bank may use n-channel transistors with the other bank uses p-channel transistors. Gate voltages may be boosted.

  • Patent number: 8894464
    Abstract: A toy with folding retractable wings includes a body and wings connected to the body via snap-in pivot articulations that allow the folding of the wings in a space minimizing nesting configuration. Various springs, latches, triggers and stopping mechanisms ensure that the folded wings deploy in a spring-loaded fashion, with minimal user effort. The pivot articulations can release the wings in a non-destructive manner when exposed to high mechanical stress loads, thus preventing destructive wing breakage.
