Abstract: An In-Flight Entertainment system is provided with a server unit and a display unit. The server unit is configured to maintain digital content. The display unit is configured to connect to the server unit through a wired network for receiving and presenting the digital content. The display unit further includes a wireless module for wirelessly transmitting the digital content received from the server unit to be presented by a first portable device.

Abstract: An assembly of a low-noise block converter and a filter for a satellite antenna includes a low-noise block converter, a filter, and a connecting component. The low-noise block converter includes an output circuit, and the filter includes a filtering circuit. The connecting component includes a sleeve part for engaging threadedly the low-noise block converter and the filter, and a core extending through the sleeve part and interconnecting electrically the output circuit and the filtering circuit. By virtue of the sleeve part of the connecting component, connection between the low-noise block converter and the filter can be reinforced to reduce interference. The sleeve part can also serve as a ground circuit between the low-noise block converter and the filter so as to shorten a ground path, thereby reducing signal loss.

Abstract: A band rejection filter capable of reducing harmonics includes a first signal end, a second signal end, a high pass filter coupled between the first signal end and the second signal end for performing high pass filtering on signals transmitted between the first signal end and the second signal end, and a low pass filter coupled between the first signal end and the second signal end for performing low pass filtering on signals transmitted between the first signal end and the second signal end. The low pass filter includes a plurality of non-magnetic-core inductors coupled in a sequence between the first signal end and the second signal end, and a plurality of capacitors respectively coupled between an intersection of adjacent non-magnetic-core inductors of the plurality of non-magnetic-core inductors and a ground end.
