    摘要: This invention uses variables sets, that are called up according to a file a into a Programmable Finite Impulse Transform (FIT) algorithm, which then sends a command to a Programmable Finite Impulse Response (FIR) filter (a brick wall filter) that makes multiple passbands. The digital passbands edit a spectral range from 200 nm to 1500 nm into multiple snippets thus generating an edited-down variation on the spectral range coming from fluorescent taggants. The full-wide peaks profile from a zone containing side-by-side fluorescent taggants is uniform on all the value documents or items in a series, but the Programmable FIT algorithm and the Programmable FIR multiple bandpass filter turn that single peaks profile signature into millions of distinct and specific variations, so each value document or item has its own unique key in a database. The full-wide emissions profile, as edited by a digital multiple bandpass filter into snippets, constitutes the product of the digital signal processing aspect of the present invention. This product can be compared on a one-to-one basis with a similarly made product on file in a database. A match of 95% to 100% causes a rating of authentic.

    摘要: A composite speaker system includes a tweeter or high frequency transducer attached to an adjustable flexible arm or arms which is mounted directly to the pole piece or adapter member connected to the pole piece of a woofer or low frequency transducer. The tweeter can be adjusted in any direction to improve the sound quality because the listener can actually aim the tweeter at himself or herself and the composite speaker system can be mounted anywhere in an automobile or room.

    摘要: A composite speaker system including a high frequency transducer and a low frequency transducer. An adjustable rod is attached to a pole piece of the low frequency transducer and a back side of the high frequency transducer. The high frequency transducer can be adjusted in any direction to improve the sound quality because the listener can actually aim the high frequency transducer at himself or herself and the composite speaker system can be mounted anywhere in a vehicle or room.
