  • Patent number: 10886420
    Abstract: The wafer-level manufacturing method makes possible to manufacture ultrathin optical devices such as opto-electronic modules. A clear encapsulation is applied to an initial wafer including active optical components and a wafer-size substrate. Thereon, a photostructurable spectral filter layer is produced which defines apertures. Then, trenches are produced which extend through the clear encapsulation and establish sidewalls of intermediate products. Then, an opaque encapsulation is applied to the intermediate products, thus filling the trenches and producing aperture stops. Cutting through the opaque encapsulation material present in the trenches, singulated optical modules are produced, wherein side walls of the intermediate products are covered by the opaque encapsulation material. The wafer-size substrate can be attached to a rigid carrier wafer during most process steps.

    Abstract: Power control in new radio (NR)-to-NR dual connectivity communications is disclosed. A UE, compatible for NR-to-NR dual connectivity, may receive a transmit power configuration and a power allocation configuration. The transmit power configuration identifies the designated reserved power for each of the cell groups participating in the dual connectivity communication. The power allocation configuration identifies to the UE whether to operate access to excess transmission power by either mode 1 rules, which may introduce phase discontinuity into ongoing transmissions, or mode 2 rules, which use a look-ahead functionality to trigger joint determination and allocation of transmission power among known uplink transmissions over a given transmission duration. After the determined transmission power allocation has been made, the UE transmits the dual connectivity transmissions according to the determined power.

  • Patent number: 10850349
    Abstract: Provided is a method for machining micro-holes in a metal or alloy product which relates to the field of micro-hole machining. The method reduces the duration of ejection of primary plasma and the residuals produced during the ejection of the primary plasma, improves the smoothness of the hole wall of the micro-hole, and increases the depth limit of the micro-hole. Injecting energy by a low-energy pulse laser in two attempts further facilitates the reduction of the diameter of the micro-hole and reduces the possibility of cracks, compared with injection of the same energy by a single high-energy pulse laser. Moreover, a ratio between the diameter of the central ring of the ring spot formed by the focused second laser beam and the diameter of the central ring of the Gaussian spot formed by the focused first laser beam is greater than 1, which can improve the injection efficiency of laser energy.
