Abstract: Adaptive control of exposure. A proportional exposure cap is a maximum fraction applicable to a recipient's total viewable attention in a time window. The total viewable attention represents all viewable advertising content which will be provided to the recipient. A notification of availability of an opportunity to expose a specified recipient to advertising content is received during the time window. The specified recipient's consumed viewable attention is detected. The specified recipient's total viewable attention for the time window is predicted. Responsive to the maximum fraction of the specified recipient's predicted total viewable attention for the time window being greater than the consumed viewable attention of the specified recipient, content is sent to the specified recipient and the consumed viewable attention is updated.

Abstract: Adaptive control of exposure. A proportional exposure cap is a maximum fraction applicable to a recipient's total viewable attention in a time window. The total viewable attention represents viewable area and exposure duration of all viewable advertising content which will be provided to the recipient. A notification of availability of an opportunity to expose a specified recipient to advertising content is received during the time window. The specified recipient's consumed viewable attention (representing viewable area and exposure duration of the advertising campaign's advertising content) is detected. The specified recipient's total viewable attention for the time window is predicted. Responsive to the maximum fraction of the specified recipient's predicted total viewable attention for the time window being greater than the consumed viewable attention of the specified recipient, the advertising campaign's advertising content is sent to the specified recipient and the consumed viewable attention is updated.

Abstract: The invention relates to a liner-free label activator, adapted to be joined to another piece of equipment, such as a thermal printer. The activator has a housing including a reservoir for containing a solvent and a pump connected to the reservoir. The activator also has an applicator connected to the pump for applying solvent to a liner-free label passing thereby, an activator control system to connect to a control system of the printer, and structure for connecting the housing to the printer.
