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 grille for an electroacoustic transducer. The grille has a frame defining a length, a width, and a depth, the frame configured to cover at least a portion of the electroacoustic transducer, and the frame configured as substantially acoustically transparent relative to the electroacoustic transducer. The frame has an energy absorption capacity such that for a mass of 6.8 kg impacting the frame at a speed of 24.1 km/h, the 3 ms deceleration is no more than 80 gs.

Abstract: To allow a manufacturer to minimize the distance between the electroacoustic transducers, arrangements of the innovation relate to a substantially flexible grille for an electroacoustic transducer. In one arrangement, the grille is manufactured from a material that substantially simulates the foam headrest material and provides a degree of rigidity to the fabric covering over the headrest. Accordingly, with the grille being manufactured from a relatively flexible material, the manufacturer can mount the electroacoustic transducers at a relatively close distance (e.g., within a 140 mm central area) while adequately supporting the perforated or acoustically transparent headrest covering material and complying with automotive safety regulations.
