Abstract: A tiled display device includes two panels and two cover layers respectively disposed on the two panels. The two cover layers include a contact region. A top portion and a bottom portion of the contact region have a height H. One of the two cover layers has a thickness Tn. One of the two panels has a distance Xn between an upper surface of the one of the two panels and the bottom portion of the contact region. The one of the two panels is corresponding to the one of the two cover layers. The height H, the thickness Tn and the distance Xn satisfy the equation: 0<H/(Xn+Tn)<0.8.

Abstract: An image sensing device and a control device of an illumination device thereof are provided. The control device includes a control circuit, an operation circuit, and multiple driving signal generators. The control circuit generates multiple control signals. The operation circuit performs a logical operation on the control signals and an image capturing signal to generate multiple operation results. The driving signal generator respectively provides multiple driving signals to the illumination device according to the operation results, and the driving signals respectively have multiple different output powers.

Abstract: An apparatus and a method for automatically establishing a new wireless link when the original wireless link between the apparatus and a commercially available FM radio receiver is interfered by other signal sources and reception conditions become poor, thereby eliminating the need to manually configure both the target FM radio receiver and the apparatus to a suitable FM frequency. The apparatus receives an audio signal, modulates and transmits the audio signal to the target FM radio receiver over a selected frequency, scans an FM spectrum for an alternative frequency, transmits an Radio Data System compatible command and a forcible switching signal to configure the target FM radio receiver to tune to the alternative frequency when signal quality of the received signal deteriorate sufficiently.
