The present disclosure relates to a mirrored serial interface (MSI) for accessing peripherals through four wire serial interface. More particularly, the present disclosure is related to serial peripheral protocol with looped back mechanism in which contents of source data line are looped back onto the destination line and compared at every clock edge to ensure data sanity and to assert presence of slave and master device during and between cycles.

Method and a mirrored serial interface (MSI) for transferring data

Methods and systems for selecting a communication channel from a plurality of available channels in an infrastructure basic service set network having a plurality of access points APs comprising: monitoring the available channels for a scan time by a co-located radio station to capture signal level from APs at each channel; calculating weighted channel power level of each channel to determine the channel with minimum power and free channels from the available channels; receiving the signal level of each channel from co-located radio station to processor and calculating weighted channel power level of each channel to select the communication channel, selecting communication channels comprises: identifying free channels; where only one free channel, select the free channel, where plurality, select the free channel with minimum interference less than a predefined value and with lower weighted channel power level, where no free channels, select the channel with minimum weighted channel power level.

Embodiments herein relate to a method and an information appliance device having a unique access card for preventing security breach in the information appliance device. A multimedia content server transmits a one-time access key to both the information appliance device and a user of the information appliance device. The user must input the access key to the information appliance device. The information appliance device verifies the access key and provides access to the user for the multimedia services, by activating a periodic activation key upon successful verification of the access key. Therefore, even if unauthorized user tries to skip the access key verification process through modification of access cards used in information appliance device, the unauthorized user cannot access the multimedia service due to lack of the periodic activation key required for activating multimedia service. Hence, security breach such as, cloning or duplication of the access cards will be minimized.

Aspects of the present disclosure aim at configuring an optical time domain reflectometry (OTDR) in a central office such that the OTDR is configured to be operatively coupled with and also configured to periodically poll each fiber at defined intervals and compute/store a reflection signature that can be used to compare with future signatures received from subsequent polls of the fiber to determine a fault (e.g., a fiber cut or breakage) between the central office (CO) and one or more optical network unit (ONU) over GIS.

Aspects of the present disclosure generally relate to a RF high power amplifier designed for resonance mitigation. A method for resonance mitigation in RF high power amplifier enclosure and an enclosure for RF high power amplifier designed to mitigate resonance is provided. In an aspect, the enclosure can be configured with a metallic post or a grounded metallic post positioned at a suitable location with RF high power amplifier circuit to dampen and shift out resonance. In an aspect, the metallic post can be placed between printed circuit board (PCB) substrate and enclosure lid. Proposed metallic post solution eliminates the need of RF absorber in the design.
