DC current cancellation scheme for an optical receiver
In high data rate receivers, comprising a photodetector (PD) and a transimpedance amplifier (TIA), a transmitted optical signal typically has poor extinction ratio, which translates into a small modulated current with a large DC current at the output of the PD.

Accordingly, cancelling photo diode DC current in high data rate receivers is important for proper receiver operation. A DC current cancellation loop, comprising a low pass filter section and a trans-conductance cell (GM) are connected to the input of the TIA. PD DC current IDC is drawn from the input node of the TIA in the GM cell, such that the cancellation loop maintains the DC voltage value of the TIA input node to be the same as a reference voltage (VREF). |

Paying for content through mining
A display device “app” maintains the processor and graphics chip of the device energized but deenergizes the display responsive to an “off” command. The energized components are used in the background for cooperative computer tasks such as bitcoin mining that can lead to remuneration, with any remuneration so received being credited to an account. When a viewer wished to view content that requires payment, the account is debited accordingly, and no further payment is demanded, and advertisements are omitted from the content. Should the account be short of necessary funds to pay for the demanded content, the “app” can present advertisements in the content and/or require input of payment. |

Machine learning assisted target segment audience generation
A segment targeting system generates target segment audiences for delivery of digital content. The segment targeting system generates hit recency and frequency summary data, which identifies hit recency and hit frequency for each of multiple cookie identifiers that satisfied a metric in at least one of multiple segments and in a time range in user specified target segment audience criteria. At least a portion of this summary data is used to train a machine learning system. The machine learning system can include multiple machine learning models, with each model being associated with a different false positive to false negative penalty ratio modelling parameter when learning recency and frequency combinations of hits on webpages in each segment that work well to separate cookie identifiers that satisfied a metric for an offering in a target segment and cookie identifiers that satisfied a metric for an offering in other segments. |
