Abstract: A screw having stacked screw heads includes a screw shank portion with a thread and a screw head portion rigidly connected to each other. The screw head portion is driven to bring the screw shank portion to rotate. The screw head portion includes a first screw head and a second screw head. The first screw head has a first shaped groove on its top plane to receive an operating torque. A neck portion is connected to a bottom plane of the first screw head and a top plane of the second screw head. The second screw head has a second shaped groove on its top plane. The neck portion or the connection between the neck portion and the first screw head or the second screw head has lower torsional endurance than each of the first screw head and the second screw head.

Abstract: A smart temperature control system of a network equipment includes a motherboard disposed on a plate of a case, wherein a cooling chip is disposed between the plate and a portion of the motherboard where a temperature-controlled member is disposed on. A system CPU controlling circuit on the motherboard receives an information of a real-time temperature and a model of the temperature-controlled member, and obtains an operating temperature range of the temperature-controlled member by comparing the information of the model of the temperature-controlled member received with different models of the temperature-controlled member in a memory. When the real-time temperature of the temperature-controlled member falls out of the operating temperature range of the temperature-controlled member, the system CPU controlling circuit controls a power-driving circuit to drive the cooling chip via voltages with opposite polarities to cool or heat the motherboard and the temperature-controlled member disposed on the motherboard.

Abstract: A multi-input multi-output antenna system capable of being disposed in an electronic device and the electronic device including the antenna system have a low-frequency antenna assembly and a high-frequency antenna assembly. The low-frequency antenna assembly includes multiple low-frequency antennas that are spaced apart from each other by a distance. The high-frequency antenna assembly includes multiple high-frequency antennas that are spaced apart from each other by a distance. One of the high-frequency antennas is structured as a low-profile dish antenna and is located between the low-frequency antennas, so that the antenna system has smaller volume and height, and better isolation and radiation patterns.

Abstract: A routing information management method adapted for a layer-3 switch is proposed. For each ARP entry in an ARP table, a processor assigns to the ARP entry an aging reference parameter that is identical to a quantity of those routing entries in an IP routing table whose next hop IP addresses are identical to the IP address of the ARP entry, and removes those ARP entries whose aging reference parameters are zero. For each routing entry in the IP routing table, when the next hop IP address of the routing entry is absent from the ARP table, the processor makes the routing entry serve as an inactive routing entry, proactively sends an ARP request for the inactive routing entry, and updates the ARP table based on a piece of ARP information received externally.

Abstract: A vehicle radar system includes an antenna module, an RF module, and a signal processor. The antenna module includes at least one transmitting antenna and multiple receiving antennas. The RF module includes a transmitting segment that generates and transmits transmitting waves each carrying a transmitting signal, and a receiving segment that receives reflected waves and incorporates received signal carried by the reflected waves with the transmitting signal into a beat signal. The signal processor performs 2D-FFT on the beat signals to obtain estimated position information of the target object, determines whether a distance value of the estimated position information is greater than a preset distance threshold, and when it is determined that the distance value is greater than the preset distance threshold, perform two-dimensional Multiple Signal Classification (2D-MUSIC) on the estimated position information, so as to obtain an exact distance value and an exact angle value of the target object.

Abstract: A floating electrical connector includes a housing with a tubular portion. An axis is defined in a center of the tubular portion. Several floating terminals are arranged around the axis and are partially connected. Each floating terminal has an inner terminal sheet on an inner side and a spring structure on an outer side. Each spring structure is connected to one of the inner terminal sheets. A portion of the inner terminal sheet is inserted into the tubular portion and arranged along an inner peripheral surface of the tubular portion. The portion of each inner terminal sheet located in the tubular portion has an electronic contact bulging inward. Several external pins are electrically connected around the floating terminals. When a conductive pin is inserted into the tubular portion, the spring structures could elastically deform, allowing the tubular portion to adapt to a horizontal deviation or a skew deviation of the conductive pin, providing a greater tolerance for alignment deviations.

Abstract: A supporting structure includes a seat, a suction cup, a rotary plate, and a support, wherein the suction cup is located at a cavity of the seat. The rotary plate is disposed between the seat and a bottom portion of the support. The support drives the suction cup to act together. By rotating the rotary plate clockwise or counter-clockwise, a distance between the bottom portion of the support and the seat could be changed to make the suction cup be attached to or removed from a smooth surface of an object. The supporting structure of the present invention facilitates the convenience of use.
