A tube or pipette-type element, such as a capillary tube or other tube element carries a drug identification system for a number of hypnotic-inducing drugs or anesthetic drugs. The drug identification system provides a visual indication of at least two or more drugs present in a liquid sample. The liquid sample is drawn into one end of the tube, moves along the tube, and functional materials and/or structure in the interior of the tube provide a visual indication of the presence of targeted contaminants (e.g., drugs) in the fluid sample. The design also minimizes or prevents any reflux of materials in the tube element back into the liquid or beverage from which the sample has been taken. An additional benefit of the system is safe disposal and moderate unit cost to the public.

A wagering terminal that also allows for account set-up has a display, a reader to accept account wagering applications, a user interface to capture user input and user identification, and a processor to process the identification, user input and account set-up. The terminal may communicate directly with wagering pools for entry into the pools and facilitates wagering on race events by providing and even analyzing race event information. A rotating slot-type image format can supply information on actual race contestants wagered upon and symbols can be used to identify multiple contestant wagering events.

A method and apparatus allows playing a wagering game. After placing a wager, the system provides multiple paylines and symbols appear on various paylines. Predetermined symbol events on paylines determine winning events and losing events. A wager is placed on more than one payline; at least one payline is designated a loss-determining payline; at least one payline is designated an influenced payline; symbols are provided to both the loss-determining payline and the influenced payline; and when the loss-determining payline has a losing event, a winning event on the influenced payline is increased.

An apparel or material which may be placed anywhere or worn about the neck or other parts of the body of a human. The apparel/material has a structure that, when repositioned from about the wearer, will retain a position about a mouth and nose of the human, as by elasticity or taughtness of a wrapping about the face. The apparel is sufficiently porous as to allow a human to breath comfortably through the fabric when placed over the mouth and nose of the human. The fabric has as a coating is created with on at least the outer surface and through at least 25% of the thickness of the fabric a moisture-sensitive antimicrobial composition, wherein the antimicrobial moisture-sensitive composition comprises an antimicrobially active compound and a carrier, the carrier by hydrophilic and able to absorb sufficient moisture from exhaled breath from the human as to maintain a wet surface on the carrier to which viral particles will adhere more strongly than to a dry surface of the same carrier.

Transactional items such as currency, credit cards, identification cards and the like can be provided with enhanced difficulty to forge or counterfeit by the inclusion of magnetic elements within the transactional item. The signal strength, period, amplitude and/or alignment of the magnetic field may be read as coded information by a magnetic reading head. The encoding of this information can be made increasingly difficult to imitate or forge by varying parameters within these (and other) mechanically readable inscriptions. Filaments coated with magnetic particles are particularly useful magnetic elements for inclusion in transactional items because of their ability to be physically aligned, extend across significant dimensions of the transactional item, and their ready inclusion into manufacturing processes for the transactional items.

Security can be enhanced for any circular casino chip, betting chip or token by a magnetically readable system that may be applied to circular casino chip, betting chip or token. A circular casino chip, betting chip or token could be constructed and having at least a first, second and third set of magnetic readable information permanently attached to the circular casino chip, betting chip or token to form a source of magnetically readable information. Each set of magnetic information may have magnetic elements comprising a fiber, magnetic material filled binder, filament or strip, said first magnetic element having at least one magnetic property along the length of said fiber, magnetic filled binder, filament or strip, or physical spacing between said first magnetic element and said second magnetic element which can be mechanically read as different from the magnetic property or position of the second magnetic element. The information can be read from the side of the chip, so that stacks of chips may be read.
