Benefits of technology

The patent describes a system that helps reduce interference between two applications running on a computing device. The system detects potential interference and adjusts the settings of one of the applications to minimize the impact on the other application. This allows for better performance and reduced degradation of the impacted application. The system can be used in a mobile device with an aggressor camera and a victim receiver, helping to mitigate the interference and keep the camera operating at its best. The technical effect of this system is improved performance and reduced interference between applications on a computing device.

Problems solved by technology

This increase in electromagnetic emissions causes electromagnetic interference (EMI) that degrades the performance of other circuitry within the mobile computing device.
Additionally, continued miniaturization of mobile computing devices, combined with increased frequencies, further exacerbates the effects of EMI.

Embodiment Construction

[0017]With reference now to the drawing figures, several exemplary aspects of the present disclosure are described. The word “exemplary” is used herein to mean “serving as an example, instance, or illustration.” Any aspect described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other aspects.

[0018]Aspects disclosed in the detailed description include adjusting application parameters for interference mitigation. In one aspect, a computing device is provided that employs a control system configured to detect and mitigate electromagnetic interference (EMI) generated within the computing device. More specifically, the control system is configured to detect possible EMI conditions and adjust parameters within the computing device to mitigate such EMI. In this manner, the computing device includes an aggressor application and a victim receiver. The control system is configured to analyze performance tradeoffs based on an acceptable performance ...

Abstract

Aspects of adjusting application parameters for interference mitigation are disclosed. In one aspect, a computing device is provided that employs a control system configured to detect and mitigate electromagnetic interference (EMI) generated within the computing device. More specifically, the control system is configured to detect possible EMI conditions and adjust parameters within the computing device to mitigate such EMI. In this manner, the computing device includes an aggressor application and a victim receiver. The control system is configured to analyze performance tradeoffs based on an acceptable performance level of the aggressor application and the performance degradation experienced by the victim receiver. Based on such analysis, the control system is configured to adjust parameters associated with the aggressor application to mitigate the EMI. Thus, the control system provides designers with an additional tool that may reduce the performance degradation of the victim receiver attributable to the EMI.

Description

BACKGROUND[0001]I. Field of the Disclosure[0002]The technology of the disclosure relates generally to electromagnetic interference (EMI) of receivers, and particularly to mitigating effects of such EMI.[0003]II. Background[0004]Mobile computing devices, such as mobile phones and computer tablets, have become increasingly prevalent in contemporary society. These mobile computing devices are commonly used for a multitude of everyday functions. For example, a mobile computing device may be used to make phone calls or send e-mail messages via a wireless modem. The same mobile computing device may also perform other functions using function-specific hardware applications, such as taking pictures with an integrated camera or viewing a video on an integrated display.[0005]In this regard, each hardware application communicates with a central processor configured to execute instructions related to such functions. More specifically, data and clock signals are exchanged between each hardware a...
