Abstract: The invention relates to a tube pump comprising an at least partly flexible tube and a pump element inserted in the tube, where the pump element comprises no more than one non-return valve member and a flow blocking member positioned a distance apart on a rod element. The non-return valve member is oriented on the rod element so as to allow for a fluid flow in the tube through the valve member along the rod element in the direction towards the flow blocking member. The flow blocking member is in a closed configuration placed to block the tube by engaging with the tube walls, and is in an open configuration configured to deform by a deformation of the tube such as to allow for fluid passage. The flow blocking member further is configured to attain its closed configuration when not opened by the tube deformation. The tube comprises an at least partly flexible tube portion between the valve member and the flow blocking member, such that a repeated deformation of the flexible tube portion acts to alternately close and open the valve member and the flow blocking device thereby generating a fluid flow through the tube. The invention further relates to an infusion pump comprising such tube pump as mentioned above.

Title: Fixed-pricing for guaranteed delivery of online advertisements
Inventor: SIMO FIDJI NAHEMA
IPC: G06Q30/02
Filed: 2014-05-21
Abstract: An online system sells fixed-price advertising guaranteeing a number of impressions or a number of actions associated with an advertisement by users of the online system. The price for an advertisement associated with a guaranteed number of impressions or actions is based on a target bid amount for selecting the advertisement from a group of advertisements using a conventional pricing scheme and a predicted likelihood that the guaranteed number of impressions or actions occur. The price may be further adjusted by a premium that accounts for a risk of revenue lost by the online system for displaying an advertisement associated with a guaranteed number of impressions or a number of actions rather than conventionally-priced advertisements.
