  • Patent number: 6259277
    Abstract: The present invention is a design paradigm for molecular scale electronic systems wherein electronic information is transmitted and processed, and electronic logic is obtained by changing the electrostatic potential of a molecule. The signal may be restored using an external potential through the underlying substrate. Several convergent synthetic routes are shown to conjugated molecules with various potential electronic device applications including a two-terminal molecular wire with a transport barrier, a molecular wire with two transport barriers, three-terminal junctions, three-terminal structures with switch-like possibilities, and four-terminal systems that could serve as logical gates without the use of multiple transistors.

  • Patent number: 6219726
    Abstract: A method and system for limiting access to a media storage device such as a tape drive unit. In accordance with the inventive method, a set of control parameters is generated for the device for a given application program. A tape control unit uses the parameters to process commands from the application program and thereby control access to the tape. In an illustrative application, an extent is defined on the tape and controls are defined which govern the type of access permitted within the extent. The system rejects any commands which attempt to access medium outside of the defined extent. Write and formatting commands within the extent are limited and partition changes, loads and unloads are prohibited.

  • Patent number: 6159473
    Abstract: A novel throat spray composition is provided that is useful for topical application to sore throats. The throat spray composition contains Piper methysticum (Kava Kava) as its main active ingredient, and is a suitable alternative to phenol-based over-the-counter throat sprays. Piper methysticum is used for its little known or utilized analgesic property, which provides a soothing and numbing effect to the throat. Additional ingredients include Echinacea angustifolia, Eucalyptus globulus, Thymus vulgaris, Lycopodium clavatum, Phytolacca decandra, Capsicum annum, Mentha piperita, and Phosphorus, which, together with Piper methysticum, offer temporary relief of sore throat pain, irritation, difficulty swallowing, and symptoms of hoarseness or laryngitis.

  • Patent number: 6160267
    Abstract: A sandwich device was prepared by electrodeposition of an insoluble layer of oligomerized tris(4-(2-thienyl)phenyl)amine onto conducting indium-tin oxide coated glass, spin coating the stacked platinum compound, tetrakis(p-decylphenylisocyano)platinum tetranitroplatinate, from toluene onto the oligomer layer, and then coating the platinum complex with aluminum by vapor deposition. This device showed rectification of current and gave electroluminescence. The electroluminescence spectrum (.lambda..sub.max =545 nm) corresponded to the photoluminescence spectrum of the platinum complex. Exposure of the device to acetone vapor caused the electroemission to shift to 575 nm. Exposure to toluene vapor caused a return to the original spectrum. These results demonstrate a new type of sensor that reports the arrival of organic vapors with an electroluminescent signal.

  • Patent number: 6155932
    Abstract: In the field of golf equipment, a new shaft design incorporates passive damping to suppress the vibrations excited in the shaft before and after impact. The design comprises a viscoelastic material sandwiched between multiple layers of composite plies which induce large shear strains in the viscoelastic when the shaft is subjected to bending, extension, or twist, thus increasing damping losses over conventional golf shafts. In one embodiment, the sandwiching layers are of opposing orientation. In another embodiment, the layers are oriented in an opposing V-shape laminate.

  • Patent number: 6137118
    Abstract: A sandwich-type, organic p-n junction photodiode is prepared by electrode-position of an insoluble layer of oligomerized tris(4-(2-thienyl)phenyl)amine onto conducting indium-tin oxide coated glass, spin-coating the stacked platinum compound, bis(cyanide)-bis(para-dodecylphenylisocyanide)platinum (II), from chloroform onto the oligomer layer, and then coating the platinum complex with a micro-array of aluminum electrodes by vapor deposition. This device shows rectification of current and gives a measurable photocurrent. The photocurrent action spectrum follows the absorption spectrum of the platinum complex; changes in the action spectrum with layer thickness point to a p-n junction formed at the interface of the molecular layers as the site of rectification. Exposure of the device to acetone vapor causes the action spectrum to shift dramatically to longer wavelength. Exposure to chloroform vapor causes a return to the original spectrum.

  • Patent number: 6124963
    Abstract: A procedure is disclosed for assembly of novel two-sided monolayer or multilayer device architectures out of self-assembly or self-organizing amphiphilic compounds derived from molecules that undergo a type of valence tautomerization known as asymmetric narcissistic reactions. The two-sided monolayer architectures are constructed by Langmuir-Blodgett (LB) transfer or self-assembly (SA) techniques while the multilayer architectures are formed by Y-type LB depositions, where the two layers or bilayers of the assemblies are alternate depositions of mirror-image forms of the amphiphiles. The resulting three-dimensional supramolecular assemblies described herein are uniquely capable of commutation between two non-centrosymmetric states which have, on a macroscopic scale, an optically antipodal relationship and a third central symmetric state which is, accordingly, optically racemic.

  • Patent number: 6075252
    Abstract: A method and apparatus for detecting the presence of a specific concentration of gaseous species within a calibrated range in a gas sample are disclosed. The ILS gas detection system of the present invention simply comprises an ILS laser and an optical detector. However, the spectral bandwidth of the ILS laser is preferably entirely included within one of the absorption bands or regions assigned to the intracavity gaseous species being monitored. Thus, within the calibrated range, the presence of the gaseous species changes the temporal characteristics of the ILS laser. Consequently, only a temporal characteristic of the output of the ILS laser need be monitored in order to quantitatively determine the concentration of the absorbing gaseous species when using the ILS method of the present invention.
