  • Publication number: 20220221731
    Abstract: A method for collimating light using a film including elongated chambers of bistable electrophoretic fluids. The light-collimating films are suitable to control the amount and/or direction of light incident to a transmissive substrate. Such films may be integrated into devices, such as LCD displays, to provide a zone of privacy for a user viewing the LCD display. Because the light-collimating film is switchable, it allows a user to alter the collimation of the emitted light on demand. Because the films are bistable, they do not require additional power after they have been switched to a display state.

  • Publication number: 20220190396
    Abstract: Articles and methods including layers for protection of electrodes in electrochemical cells are provided. As described herein, a layer, such as a protective layer for an electrode, may comprise a plurality of particles (e.g., crystalline inorganic particles, amorphous inorganic particles). In some embodiments, at least a portion of the plurality of particles (e.g., inorganic particles) are fused to one another. For instance, in some embodiments, the layer may be formed by aerosol deposition or another suitable process that involves subjecting the particles to a relatively high velocity such that fusion of particles occurs during deposition. In some embodiments, the layer (e.g., the layer comprising a plurality of particles) is an ion-conducting layer.

    Abstract: The present invention provides a method for detecting motor initial phase and phase sequence and a system for controlling a permanent-magnet synchronous motor. The method is applied to the system and comprises sequentially acquiring, through an encoder, first displacement data which register the encoder's reading when a rotor spins to a Q-axis, second displacement data which register the encoder's reading when the rotor spins from the Q-axis to a D-axis, third displacement data which register the encoder's reading when the rotor spins from the D-axis to a negative Q-axis and fourth displacement data which register the encoder's reading when the rotor spins from the negative Q-axis to the D-axis; obtaining an initial phase of the motor to be detected according to the second displacement data, the fourth displacement data and the encoder's CPR; and determining the phase sequence of the motor based on the first displacement data, the second displacement data and the encoder's CPR.

  • Patent number: 11286425
    Abstract: A method for preparing needle coke for ultra-high power (UHP) electrodes from heavy oil is provided. In this method, heavy oil is used as a raw material. The size exclusion chromatography (SEC) is conducted with polystyrene (PS) as a packing material to separate out specific components with a relative molecular weight of 400 to 1,000. The ion-exchange chromatography (IEC) is conducted to remove acidic and alkaline components to obtain a neutral raw material. The neutral raw material is subjected to two-stage consecutive carbonization to obtain green coke, and the green coke is subjected to high-temperature calcination to obtain the needle coke for UHP electrodes. The needle coke has a true density of more than 2.13 g/cm3 and a coefficient of thermal expansion (CTE) of ?1.15×10?6/° C. at 25° C. to 600° C.
