Methods and systems for detecting alignment of a substrate during a printing process are described. In an embodiment, a printing apparatus may comprise an apparatus polarization area. A substrate may be configured with a substrate polarization area. The substrate may be arranged on the printing apparatus during printing such that the substrate polarization area overlaps the apparatus polarization area to form an alignment area. During printing, light may be radiated onto the alignment area to generate polarized light. The polarized light may be received by a polarized light receiving device. Characteristics of the light received by the polarized light receiving device may be monitored for variations. The variations may indicate that the substrate is not properly aligned for printing on the printing apparatus.

Technologies are provided for filtering user's actions based on user's mood. User's actions may include online actions. To prevent 'in the heat of the moment' actions, which a user may regret later, a mood based filter may identify a user action such as posting a message to a social network, a professional network, an email network, a blog, or an instant message network. An automatic system action may then be taken based on the detected user's mood. In some examples, the user's mood may be assigned to a numeric or alphanumeric category. Various system actions such as blocking or delaying the user action may be tied or associated to the user's mood category through one or more predefined, customizable rules. In other examples, a user confirmation of the user action may also be included in addition to the automatic system action.
