Abstract: The present invention provides a control method of a receiver. The control method includes the steps of: when the receiver enters a sleep/standby mode, continually detecting an auxiliary signal from an auxiliary channel to generate a detection result; and if the detection result indicates that the auxiliary signal has a preamble or a specific pattern, generating a wake-up control signal to wake up the receiver before successfully receiving the auxiliary signal having a wake-up command.

Abstract: A net structure includes a plurality of metal rightwards inclined wires including, in sequence, a first rightwards inclined wire, a second rightwards inclined wire, and an N-th rightwards inclined wire. The net structure further includes a plurality of metal leftwards inclined wires including, in sequence, a first leftwards inclined wire, a second leftwards inclined wire, and an N-th leftwards inclined wire. The first rightwards inclined wires intersects, in sequence, from the first rightwards inclined wire through the N-th rightwards inclined wire at an intersection at which a twine portion is formed. The second rightwards inclined wires intersects, in sequence, from the second rightwards inclined wire through the N-th rightwards inclined wire at an intersection at which a twine portion is formed. The N-th leftwards inclined wire intersects the N-th rightwards inclined wire at an intersection at which a twine portion is formed, thereby forming a net structure with a plurality of hexagonal meshes.
