Abstract: Systems and methods are disclosed for tracking user access to an advertisement and user transactions with an electronic commerce computer associated with the advertisement. In accordance with one aspect of the disclosed technology, a transaction tracking computer associates an identifier with each access (e.g., click) of an advertisement. Transactions that occur at the electronic commerce computer that are related to the advertisement will be reported to the transaction tracking server together with the identifier. In one embodiment, if the reported transaction is a duplicate of a previously reported transaction, then the reported transaction is determined to be invalid. In one embodiment, if the reported transaction occurs more than a predetermined amount of time after the time the identifier was initially generated, then the reported transaction will also be determined to be invalid.

Abstract: A ligature for affixing a reed to the mouthpiece of a woodwind instrument, primarily saxophones and clarinets. A spiral of non-stretching cord, with a mechanism for defining the spiral's shape and for providing a way of tightening it, extends around the reed and the mouthpiece. The mechanism is suspended and tightened by a vertical bridge and an integral puller assembly. The spiral cord passes through holes in the puller. The puller is raised by way of a tightening nut through a non-resonant bridge all of which tightens the spiral cord to firmly hold the reed to the mouthpiece. The bridge bears down against the mouthpiece which applies force to the bridge's contact points. The tension of each wrap of the spiral is equalized by the forces upon the bridge and the puller's design. The spiral cord is damped from extraneous vibration by use of spacing combs and by way of this self equalizing design.

Abstract: A film spool storage case includes a main housing having a base and a side wall, the base and the side wall defining a cavity for receiving a plurality of film spools therein, the side wall having a height at least as great as the heights of the spools and the side wall defining an opening at an upper end thereof; a cover releasably securable to the housing in covering relation to the opening; and a plurality of positioning projections secured to the base for positioning the film spools in the cavity in spaced relation.
