Abstract: Techniques to reduce signal interference between wired signals communicated within an electronic device and wireless signals transmitted to or received from antennas of the electronic device are disclosed. The electronic device includes an interposer with an inner fence and an outer fence having offset gaps to prevent a pathway otherwise formed by overlapping tabs, where the pathway allows noise leakage from the wired signals. In some embodiments, the electronic device (e.g., in a main logic board package) includes a ground fencing of ground vias to prevent the noise leakage from harmonics associated with signal vias communicating the wired signals. The spacing between the ground vias is based on frequencies of signals that the ground vias are intended to block.

Abstract: A method of manufacturing circuits of a substrate of a display device is provided. The method includes aligning and attaching a mask with multiple slots to a circuit area of the substrate; printing a printing material in the slots of the mask using an inkjet printing technology, so that the printing material is attached to the circuit area; removing the mask from the substrate; and curing the printing material on the circuit area to form a plurality of the circuits.

Abstract: A pneumatic conveying system for conveying bulk material, the system comprising: an adjustable pneumatic gas flow connected to a pipeline, the pipeline being suitable for conveying bulk material; a measurement device for measuring the variability of particle velocity of a bulk material being conveyed through the pipeline; and a control apparatus, operatively connected to the adjustable pneumatic gas flow and the measurement device; wherein in use, the measurement device outputs the variability of velocity data to the control apparatus. The control apparatus analyses the variability of velocity data, and regulates the rate of the pneumatic gas flow based on the analysis of the variability of velocity data.

Abstract: A surface coloring method of a magnesium alloy article includes: performing an anodizing treatment on the magnesium alloy article to form an anodized layer having a plurality of pores on an outer surface of the magnesium alloy article; performing an etching treatment on the anodized layer to form a plurality of pits on a surface of the anodized layer that is distant from the magnesium alloy article, in which each of the plurality of pits is in spatial communication with at least one of the plurality of pores; and performing a sealing treatment on the anodized layer after the etching treatment, so that a sealing layer is formed to seal the plurality of pores on the anodized layer. By using the surface coloring method, a surface-colored magnesium alloy article is also provided.

Abstract: A production method of a backlight plate, a backlight plate and a backlight module are provided. The method includes providing a light-transmitting substrate which comprises a first area and a second area, forming a pad on the light-transmitting underlay substrate corresponding to the first area, coating a layer of photosensitive material on the light-transmitting substrate and the pad to form a reflective layer, exposing a position of the second area at opposite sides of the light-transmitting substrate that the reflective layer corresponds to, and developing the reflective layer to form a groove for exposing the pad on the first area that the reflective layer corresponds to. The present disclosure ensures the stability of the reflective layer and enhances the overall reflectance of the backlight plate.

Abstract: A palm rest with a detachable assembly mechanism attaches to a keyboard via the detachable assembly mechanism. The palm rest has a shell and at least one assembly mechanism. The shell forms a concave portion. The assembly mechanism has a base and a joint arm. The base is disposed in the concave portion of the shell. One end of the joint arm is pivotally mounted on the base so that the joint arm is rotatable and retractable in order to be received in the concave portion. The other end of the joint arm can extend outside the shell for assembly with the keyboard.
