摘要： A circuit board mounting support for supporting a first electronic circuit integration includes a bearing member. The first electronic circuit integration includes a circuit board, an electronic component engaged with a first surface of the circuit board, and multiple legs for engaging with the bearing member. The circuit board has a mounting area for mounting the electronic component and a second surface opposite to the first surface. The bearing member includes a groove and an engaging portion connected to a peripheral edge of the groove. A corresponding area is defined on the bearing member and corresponds to the mounting area of the circuit board. When the bearing member is engaged with the circuit board, an opening of the groove and the engaging portion face the second surface. A junction that each of the legs is engaged with the bearing member is located out of the corresponding area.

摘要： A wireless communication device includes a casing having a wireless signal penetrating area, an antenna sending a wireless signal through the wireless signal penetrating area, and an electromagnetic lens assembly including a lens barrel and a lens. The lens barrel has a first end and a second end. The first end is closer to the wireless signal penetrating area than the second end. The lens disposed in the lens barrel has an incident surface and an emission surface on an axis of the lens. The incident surface is a flat surface facing the first end. The emission surface is a convex surface and has a curvature, which is not equal to 0, from a perspective of a first axis perpendicular to the axis of the lens, and has a curvature of 0 from a perspective of a second axis perpendicular to the axis of the lens and the first axis.

摘要： A network switch can include a precision time protocol (PTP) module and a circuit board. The PTP module can provide a first clock signal and include a predetermined interface. The circuit board can include a socket, an oscillator and a selection unit. The socket can be inserted by the predetermined interface to receive the first clock signal. The oscillator can provide a second clock signal. The selection unit can include a first terminal, a second terminal, an output terminal and a selection terminal. The first terminal can receive the first clock signal when the predetermined interface is inserted into the socket. The second terminal can receive the second clock signal. The output terminal can output one of the first clock signal and the second clock signal. The selection terminal can receive a selection signal to control the output terminal to output the first clock signal or the second clock signal.

摘要： A time synchronization device performs a time synchronization process with a device that provides first and second time values. The time synchronization device includes a packet processing circuit, a time counting circuit, and a processor. The packet processing circuit includes a timestamp counter having an N-bit length, and the packet processing circuit provides first to third time counting values. The processor calculates the first offset value based on the first and second time values and the first and second time counting values; calculates the first adjustment value based on the first offset value and the reciprocal of the frequency of the time counting circuit; calculates a second quotient value and a second remainder value based on the first adjustment value and the N-bit length; and calculates the receiving time of the second synchronization packet based on the N-bit length, the second quotient value, and the third time counting value.

摘要： A wireless access point device includes a main frame, a transmission assembly, an antenna module and a fixing assembly. The main frame includes a casing and a first connection portion connected to the casing. The transmission assembly is disposed in an internal space of the casing and provided with a signal transceiving element. The antenna module includes a waveguide, a second connection portion and a positioning recess. The second connection portion is disposed on the waveguide and detachably connected to the first connection portion to be coupled to the signal transceiving element. The positioning recess is formed on the second connection portion. The fixing assembly is movably disposed on the first connection portion. The antenna module is thereby fixed on the casing, when the second connection portion and the first connection portion are fixed through the fixing assembly removably inserting into the positioning recess.

The plate is provided on the circuit board and near a front edge of the circuit board, wherein the plate has a plurality of openings. The integrated circuits are provided on the circuit board, including a first processor and a second processor, which consume the most power. The first processor and the second processor are arranged in a staggered way. Each of the heat sinks abuts against the first processor and the second processor, respectively. An area of each of the heat sinks is greater than an area of each one of the first processor and the second processor. Whereby, effective heat dissipation could be achieved.
