Abstract: An article inventory tracking and control system tracks and controls removal of articles from a secured facility. Exemplary facilities in which the system may be useful include libraries, rental stores and retail stores. Each article is marked with an EAS marker to prevent unauthorized removal. In the system, each user of a facility and each article in the facility is uniquely identifiable. Upon receiving the user and article information, the system queries a central database to ensure that the user is a valid user and that the desired transaction is authorized. A receiving compartment is specifically designed to receive a particular type of article, such as a video or audio cassette. Sensors in the receiving compartment ensure that the article is properly placed within the receiving compartment. Proper placement of the article within the receiving compartment ensures that the marker is properly re/desensitized, and also ensures that only one transaction on one article can be performed at a time.

Abstract: An article comprises a containment means comprising pressurized gas-filled microbubbles, the gas being controllably releasable on demand by fracturing the microbubbles.

Abstract: A reflector for reflecting light from an elongate light source into the input end of a light guide having a diameter “D”. The light source is inserted through the narrow end of a collimating reflector which has a wide end with a diameter exceeding “D” through which light is emitted into the guide. The wide end of an output reflector circumferentially surrounds the collimating reflector's wide end. The output reflector's narrow end circumferentially surrounds the light guide's input end. The wide end of an input reflector circumferentially surrounds the collimating reflector's narrow end. The reflectors are cylindrically symmetrical about a common axis. Light passing from the light source to the collimating reflector is reflected, producing an output beam whose width varies as a function of distance along the axis. The light guide's input end is positioned along the axis to minimize the width of the output light beam.

Abstract: Conformable pressure-sensitive adhesive tapes which comprise a layer of polymeric foam in the backing and may be adhered firmly to a substrate and thereafter removed therefrom after only being stretched at an angle no greater than about 35° from the surface of the substrate. Articles for mounting an object such as a picture to a surface such as a wall comprising a pressure-sensitive adhesive tape of the invention are also described.

Abstract: 1H,lH-perfluorocyclohexylmethyl 2-fluoroacrylate, and homopolymers thereof.

Abstract: Embossed oriented thermoplastic films and a method of making same are described. The embossed oriented thermoplastic films have substantially the same mechanical properties as unembossed oriented thermoplastic films. The method includes providing an oriented thermoplastic film having first and second major surfaces, softening at least one of the first and second major surfaces to produce a softened surface, embossing the softened surface to produce an embossed oriented thermoplastic film, and cooling the embossed oriented thermoplastic film.

Abstract: A color mapping method is used in transforming colors between color imaging systems. The method includes using forward transformation profiles that characterize the color imaging systems to generate respective sets of device-independent color values for the color imaging systems. Color conversions are calculated by reducing differences between the respective sets of device-independent color values. Based on these color conversions, a color map is constructed that describes a relationship between the color imaging systems.

Abstract: This invention pertains to an abrasive article comprising precisely shaped particles. The abrasive article may be a coated abrasive article, a bonded abrasive or a nonwoven abrasive article. The precisely shaped particles may further comprise abrasive grits, fillers, grinding aids and lubricants.

Abstract: A filtering face mask that covers at least the nose and mouth of a wearer and that includes an exhalation valve. The exhalation valve opens in response to increased pressure when the wearer exhales to allow the exhaled air to be rapidly purged from the mask interior. An exhale filter element is placed in one of several locations in the exhale flow stream to remove contaminants from the exhaled air. The face mask is beneficial in that it provides comfort to the wearer by allowing warm, moist, high-CO2-content air to be rapidly evacuated from the mask interior through the valve and also protects the wearer from splash fluids and polluted air while at the same time protecting other persons or things from being exposed to contaminants in the exhale flow stream.
