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.

The RGB image includes a plurality of pixels. The dark channel matrix includes, for each pixel of the plurality of pixels, a minimum color component intensity for a respective pixel area centered at the respective pixel. The atmospheric light matrix includes an atmospheric light component value for each of the plurality of pixels.

Abstract: The present disclosure provides a method for determining an ore-forming environment of a porphyry deposit based on a tourmaline component, including the following steps: collecting a tourmaline-containing rock in the porphyry deposit to obtain a rock sample; performing pretreatment on the rock sample to obtain a treated sample; performing an in-situ tourmaline trace element test on the treated sample to obtain a test result; performing data processing and interpretation on the test result to obtain tourmaline trace element data; establishing a discrimination factor based on the tourmaline trace element data; and determining the ore-forming environment based on the discrimination factor. The present disclosure can quickly recognize a forming environment of a newly discovered porphyry deposit, thereby summarizing a rule and quickly giving guidance for a next prospecting direction.

Abstract: A remote software debugging method for embedded terminals makes it possible to reduce additional hardware dependencies and storage space occupation based on a CoreSight debugging framework and a dynamic command system. Series communication is used as a lead study to reduce the pre-exploration difficulty of complex communication modules and facilitate subsequent extraction of the commonalities of the communication modules. An FPB (flash patch and breakpoint) unit in CoreSight debugging framework provides a basis for setting and responding to breakpoints, debugging information for the breakpoints can be extracted and output by debug monitoring exceptions, and dynamic commands are used as carriers of overall functions to fulfill rich debugging functions such as starting and exiting of a debugging mode, setting and cancelling of breakpoints and control over program running state.

Abstract: An embedded terminals remote online development system is divided into three parts: an embedded terminal, a cloud forwarding platform and an IDE. Under remote online development, the cloud forwarding platform establishes a communication connection with the IDE through the Internet and establishes a connection with a communication module of the embedded terminal through a communication base station, so that the communication between the IDE and the embedded terminal is completed. To be compatible with a local development mode, it is also possible to establish a connection between the IDE and the embedded terminal in a wired manner such as serial communication, to realize local online development.
