    摘要： A fully integrated key fob wherein its base portion and extending tab are injection molded together, to form an integral structure. The extending tab has an aperture also molded therethrough, and into which and through the key ring may be inserted, for retention of other miscellaneous items to the key ring, during usage. Also disclosed is an apparatus and method for making the key fob.

    摘要： A multi layer interference coating comprising at least one multi layer stack deposited on a reflective layer (9), wherein each multi layer stack comprises a first dielectric layer (11), a layer of asbsorbing material (10) and a second layer of dielectric material (11) arranged in series and having a reflectance spectrum in the infrared region comprising at least one maximum. The dielectric layers are of equal optical thickness and typically are of the same material. The multi layer structure of the coating is such that incident electromagnetic radition, for which odd multiples of half wavelengths correspond to the optical thickness of the multi layer coating at the incident wavelength do not propagate within the coating and reflection at these wavelengths, is suppressed. Coatings may therefore be designed to have a near satured color in the visible wavelength spectrum. The reflective layer may be a metal or a conducting oxide, a conducting nitride, a conducting silicide or a conducting sulphide. The absorbing layers may be Cr, V, Pd, Ni, Pt, conducting oxides, or substoichiometric metal oxides, such as TiOx. In one form of the coating, where a non-metal absorber is used, the second dielectric layer may be removed in at least one of the multi layer stacks. The coating may be incorporated in a system for verifying the authenticity of an article.

    摘要： Inexpensive wideband transducers convert low frequency components (i.e., approximately 50 Hz through 800 Hz) of an audio signal to mechanical vibrations at the same frequencies so that the vibrations may be perceived at the user's skin, typically at a hand or finger. The transducer may be a small permanent magnet moving coil loudspeaker with most of the diaphragm cone removed to minimize soundwave generation, or it may be a small d.c. or stepping motor arranged to have its drive shaft rotated in alternate directions through small angles corresponding to signal amplitude. Vibrations may be applied to the user's hand through a hand-held case vibrating with the motor, or to a finger via a contactor extending outside the case from the motor or loudspeaker. The transducer has particular utility in conjunction with closed captioned in television programs to enhance appreciation of speech therein while also training the user in utilizing the transducer. One or more fixed frequency transducers may additionally be employed vibrations at a single frequency representing all of the higher frequency components in the audio signal.
