  • 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.

  • Publication number: 20190188500
    Abstract: An apparatus for monitoring an object in a low light environment includes an image capturing unit, a vehicle speed unit, an image recognizing unit, and an object determining unit. The image capturing unit continuously captures and outputs time-sliced images. The vehicle speed unit detects and outputs current vehicle speed information. The image recognizing unit recognizes a region having pixel brightness higher than a threshold in each of the time-sliced images and marks the region as a high brightness block. The object determining unit selects at least two successive time-sliced images having high brightness blocks in a continuous corresponding variation relationship from the time-sliced images, generates and outputs estimated speed information, and when the estimated speed information is different from the current vehicle speed information, determines that the high brightness block is a moving object block and monitors the moving object block.

  • Publication number: 20180334068
    Abstract: A car safety seat is disclosed in the invention, including a main body and a flexible layer. Multiple air vents are formed on the main body and penetrate through the main body along a front-to-rear direction. The flexible layer is formed on a surface of the main body and in the air vents. The multiple air vents enable vapor to pass through the main body without being blocked by the main body during a foaming process, which thereby allows foaming particles to fully contact with the vapor to ensure an enhanced foaming effect. Also, the flexible layer is not only formed on the surface of the main body but also formed in the air vents to fill the air vents, and thereby the flexible layer is more tightly combined with the main body to reduce a risk of detachment from the main body.
