摘要： A microwave broadside coupled balun integral in a multi-layer printed wiring board formed by broadside coupled conductors embedded in the multi-layer printed wiring board. The balun may be used to form components which are integrated into the multi-layer printed wiring board, such as a microwave mixer formed by two of said broadside coupled baluns embedded in a multi-layer printed wiring board and connected to a diode ring quad.

摘要： A UV sterilization device for a container includes a housing, a base, a receiving room formed between the housing and the base, a transmission member symmetrically and rotatably mounted on the base and including a clamp for clamping the container, an extension rod symmetrically mounted on the base and inserting into the container to stretch out and draw back relative to the container along the axial direction of the extension member, a UV sterilization member mounted on the extension member to move with the extension member, and a driving member fixed with the base and including a motor therein. The motor is fixed with the transmission member and the extension member. The motor can drive the transmission member and the container to rotate, and drive the extension member to stretch out and draw back relative to the container along the axial direction of the extension member to further drive the UV sterilization member to disinfect the container.

摘要： A printed circuit board (PCB) including a notch filter, or other suitable filter, is implemented in a communication device for attenuating RFI in transmissions sent from the communication device. The filter includes filter line that runs between at least two conductor layers on the PCB, in a substantially repeating pattern, which maximizes the space available on each conductor layer for additional uses.

摘要： Method embodiments for achieving hyperframe symbol synchronization are disclosed, along with device and system embodiments for implementing such methods. In one embodiment, the method comprises: receiving a pilot signal having at least two phase states; measuring the pilot signal as a sequence of measured symbols; and determining an alignment offset upon detecting between adjacent measure symbols a phase difference greater than a predetermined threshold. The alignment offset determination may include: forming a data field of four measured symbols around the detected phase difference; searching for the position of a two-symbol window in the data field that maximizes a phase difference; and calculating the alignment offset from this position.
