Abstract: The disclosure provides an electromagnetic wave adjustment apparatus includes a control circuit, a transistor circuit die and an electronic assembly. The transistor circuit die receives a control signal from the control circuit and drives the electronic assembly.

Abstract: In a method of manufacturing a photo mask, a resist layer is formed over a mask blank, which includes a mask substrate, a phase shift layer disposed on the mask substrate and a light blocking layer disposed on the phase shift layer. A resist pattern is formed by using a lithographic operation. The light blocking layer is patterned by using the resist pattern as an etching mask. The phase shift layer is patterned by using the patterned light blocking layer as an etching mask. A border region of the mask substrate is covered with an etching hard cover, while a pattern region of the mask substrate is opened. The patterned light blocking layer in the pattern region is patterned through the opening of the etching hard cover. A photo-etching operation is performed on the pattern region to remove residues of the light blocking layer.

Abstract: An antenna module includes a first metal plate and a frame body. The frame body surrounds the first metal plate. The frame body includes a first antenna radiator, a second antenna radiator, a third antenna radiator, a first breakpoint and a second breakpoint. The first antenna radiator includes a first feeding end and excites a first frequency band. The second antenna radiator includes a second feeding end and excites a second frequency band. The third antenna radiator includes a third feeding end and excites a third frequency band. The first breakpoint is located between the first antenna radiator and the second antenna radiator. The second breakpoint is located between the second antenna radiator and the third antenna radiator. An electronic device including the above-mentioned antenna module is also provided.

The third portion is located on the third surface and is connected to the second section and the fourth section. The fourth portion is located on the fourth surface and is connected to the fifth section, the sixth section, and the third portion. The radiator is adapted to resonate at a low frequency band and a first high frequency band.

Abstract: A method is disclosed for locating a plurality of tire condition sensing apparatuses mounted on a vehicle. At first, all of the antennas in the vehicle are maintained at an activation status for receiving and decoding a signal transmitted from one of tire condition sensing apparatuses of the tired, and a signal intensity is obtained. When a tire condition sensing apparatus is assured to continuously emit the signal, the antennas are alternatively turned on an off so as to obtain a plurality of signal intensity changes, and the tire condition sensing apparatus is located on the tire to which the antenna producing the maximum value of the signal intensity changes is corresponding.
