  • Publication number: 20170127003
    Abstract: An imaging system includes an image sensor and a row-period compensator. The image sensor includes an array of photosensitive pixels and electrical circuitry for controlling the array of photosensitive pixels and for reading accumulated electrical charge therefrom. The electrical circuitry is at least partially powered from a positive power rail and a negative power rail. The row-period compensator is for compensating for a change in current drawn by the electrical circuitry during at least part of a row-period of the image sensor, and the row-period compensator is electrically coupled between the positive and negative power rails. A method for compensating for a change in current drawn by electrical circuitry of an image sensor includes controlling a magnitude of compensation current drawn by a row-period compensator, to compensate for a change in current drawn by the electrical circuitry of the image sensor.

  • Publication number: 20170063763
    Abstract: In various example embodiments, a system and method for generating a proxy email address for routing messages are presented. An email directed to a user with a proxy email address assigned by the system and with no registered email address is received at a proxy email address. Whether or not the email contains an action message identifier is ascertained. Based on the email containing an action message identifier, a forward email is identified. Text content from the forward email is extracted. A short message based on the extracted text content is generated. At least one communication channel to send the short message is selected based on an engagement level associated with the at least one communication channel. The short message may be caused to be presented at a mobile device associated with the user via the selected communication channel.
