Abstract: This invention improves upon existing pay-per-click arrangements periodically generating a code associated with the search-engine users. This code, preferably in the form of a serial number, is compared to the user of the website, such that by observing a metric like the number of clicks for a given period of time, be it a short time or a longer period, such as a day or a week, the system can automatically determine if certain clicks are illegitimate. This allows the pay-per-click company to more fairly invoice the merchants, thereby preventing fraudulent over use.

Abstract: A blood pressure cuff including an inflatable bladder disposed between an elastic, resilient inner layer of material and at least one outer layer of material. The bladder is secured to these layers along the elongate ends but not along the elongate edges. The bladder is not laterally constrained during inflation. The cuff is formed into a cylindrical shape having a fixed outer diameter and includes a backing layer and apparatus for securing the bladder to a layer of the cuff to hold the bladder in place during donning of the cuff. Because the bladder is not constrained along its contact-width edges, the shape of the bladder automatically adjusts to provide a longer contact surface for larger arms and a shorter contact surface for smaller arms. The cuff is especially suited for use as a closed cuff in an automated blood pressure measurement machine or in stand-alone measurement use.
