A mobile terminal, comprises: a case including a conductive metal part; a main board mounted inside the case and having a power supply part and a ground surface; a first antenna radiator disposed so as to be spaced from the power supply part to the first antenna radiator; a power supply line for electrically connecting the power supply part to the first antenna radiator and ground line for electrically connecting the ground surface to the metal part and the first antenna radiator, thereby preventing a decrease in the performance of an antenna since the formation of an electromagnetic field between the case of a metallic material and the main board can be minimized even if the metallic material is used for the case.

A device, method, and computer-readable medium are provided for mitigating signal interference at a base station. Signal interference can be generated from subcomponent levels at a base station (e.g., electronic antenna motors) due to non-optimal designs or electric ground interferences. Generally, when power is provided to such subcomponent(s), a noise or harmonic can be inadvertently generated, falling into one of the operating bands of the base station, and negatively impacting system performance. As such, embodiments can be configured to dynamically ascertain a noise baseline associated with the base station, determine that one or more of the subcomponents are at fault for interfering with the base station operating band(s), and mitigate the interfering signal for a period that least impacts system performance.

The present invention is generally a movable barrier system that employs a movable barrier operator with a signal translation module, which enhances the quality of communications between wired components of a movable barrier system, including long distance wired communications between controllers and position sensors.

A surface acoustic wave (SAW) filter that receives an aggregate circuit and outputs two or more sub-signals on outputs each of a different frequency band. The sub-signals are amplified by low noise amplifiers and, in one implementation, the amplified sub-signals can be summed. The outputs are connected via a switched passive network so that portions of the sub-signals on the outputs that are not in the selected frequency band are at least partially terminated.

A method, including receiving an input analog signal containing noise at a specific noise frequency and digitizing the input analog signal to form a digitized signal. The method also includes recovering a first amplitude and a first phase of the noise from the digitized signal, and generating an analog correction signal at the specific noise frequency.
