  • Publication number: 20190229755
    Abstract: An antenna apparatus, an electronic apparatus and an antenna modification method are provided. The electronic apparatus includes a multiplexer and the antenna apparatus. The multiplexer combines a control signal and a first radio frequency (RF) signal to form a combination signal. The antenna apparatus includes a feeding portion, a de-multiplexer, a modification circuit and a radiation portion. The feeding portion receives the combination signal. The de-multiplexer separates the combination signal into the control signal and the first RF signal. The modification circuit receives the control signal and the first RF signal, and modifies an impedance. The first RF signal is influenced by the impedance to form a second RF signal. The radiation portion receives the second RF signal. Accordingly, merely single cable would be needed for feeding signals into the antenna apparatus.

  • Patent number: 9368900
    Abstract: A power socket structure for outdoor electric extension line is disclosed, comprising one or more power sockets, a socket body including a first pivotal axis and a second pivotal axis, a fixation case and a cone, wherein the cone is fixedly combined with at least a sidewall of the fixation case, and the socket body is pivotally connected onto the fixation case such that the socket body can rotate within the fixation case. Upon inserting a power plug of an electric product into the power socket, the power plug can bring the socket body to rotate within the fixation case so that the power socket of the socket body always faces towards the electric product thereby preventing the product power line of the power plug from wrapping around the socket body which may otherwise cause troublesome power line entanglements.

  • Patent number: 9219339
    Abstract: A computer host power management system having extension cord sockets is disclosed, comprising a socket body providing alternative current (AC) power to a computer host, in which the socket body includes AC power output plugholes, an AC power input plug, a control device and a power supply device. Herein the control device is configured with Universal Serial Bus (USB) ports and capable of determining whether the computer host signal transferred from the USB port is normal. In case of abnormal conditions, a second microprocessor in the power supply device is driven to cause a power automatic switch to turn off the AC power such that the computer host enters into the shutdown status. Later, after a lapse of preset time, the second microprocessor drives once again the power automatic switch to turn on AC power thereby rebooting the computer host.

  • Patent number: 9059529
    Abstract: A power outlet having a base, a top cover, a safety shutter, and an elastic member is disclosed. The base may include a support platform having a first electrode and a second electrode. The top cover may include a first receptacle and a second receptacle and overlaying the base. When in a first position, the safety shutter may be placed at a fulcrum of the support platform with equilibrium and mask the first electrode and the second electrode. The safety shutter may include a first incline and a second incline. When a foreign object invades either the first receptacle or the second receptacle, the safety shutter may lose its equilibrium despite still masking the first electrode and the second electrode. Only after the corresponding plug pins have been inserted into the receptacles before the safety shutter may be pushed away from the first position.
