Abstract: An imaging apparatus and method in which the focus of the imaging apparatus can be adjusted.

Abstract: A method and apparatus that allows the adjustment of the intensity of the illumination source in a barcode reader, using the barcode reader as the measuring device, to give a predetermined amount of light from a known target. The adjustment of the intensity of the illumination source in the barcode reader compensates for the manufacturing tolerances of the barcode reader.

Abstract: An electrical system for measuring humidity which is capable of measurements accurate to +/−6 percent from board to board. The accuracy provided by this electrical system makes it possible to correlate errors in data on backup magnetic tapes to variations in humidity. The electrical system consists of an oscillator whose frequency is dependent on the capacitance of a capacitor used in the circuit. The capacitance value of the capacitor is dependent on the relative humidity. The frequency of the oscillator is translated to a humidity value by an electronic counter and a microprocessor.

Abstract: An apparatus and method for detecting a data cartridge in a cartridge engaging assembly. A signal emitter may be positioned adjacent the cartridge engaging assembly to emit a signal. A signal detector mounted to the cartridge engaging assembly may detect the signal. The signal detector generates output to indicate whether the data cartridge is present in the cartridge engaging assembly based on the detected signal.

Abstract: An alignment system for an imaging apparatus is disclosed. The alignment system aligns the image beam associated with the imaging apparatus relative to predetermined reference points, such as the vertex and base of a right triangle. The base of the right triangle may be normal to the image beam and the vertex of the right triangle may be located at a fixed and predetermined location relative to the imaging apparatus. The image beam may intersect a hypotenuse point on the hypotenuse of the right triangle and the image beam may intersect a base point on the base of the right triangle. The alignment system measures the distance between the base point and the hypotenuse point. The distance between the base point and the hypotenuse point corresponds to a single location on the base relative to the vertex. The alignment systems, thus, references the transverse position of the image beam relative to the vertex.

Abstract: Disclosed are compositions and/or paints containing hydrolytic enzyme(s), microorganism(s), or mixtures of the hydrolytic enzyme(s) and microorganism(s), wherein the microorganism or hydrolytic enzyme remove undesired growth from a surface. Such compositions and/or paints may contain a catalytically effective amount of an inorganic salt. Also disclosed are articles coated with the composition and/or paint. Finally, methods are disclosed for reducing fouling of a marine surface, for reducing marine corrosion, for limiting absorption of water by a marine surface, for reducing the coefficient of drag of a marine surface, removing marine growth from a marine surface, and for reducing mildew fungus on a marine surface.

Abstract: A system to guide a media handler used by an automated media exchanger is disclosed. The automated media exchanger is of the type that uses an imaging apparatus to identify media located in the automated media exchanger. The imaging apparatus images a guidance target that is affixed to a predetermined location relative to media within the automated media exchanger. The guidance target comprises a first edge and a second edge, wherein the first edge and the second edge define boundaries of reflective difference. A first axis intersects the first edge at a first point and the second edge at a second point. The distance between the first point and the second point corresponds to a location on a second axis. The system measures the distance between the two points to correlate the location, relative to the second axis, where the target was imaged. The location of the imaging apparatus and, thus, the media handler, may, be readily determined relative to the media.

Abstract: Methods and apparatus for quantifying the amount of backlash in drive trains. Using two optical transducers techniques are disclosed that lend themselves to self diagnosis of backlash in drive train systems. The techniques are useful in autochanger drive systems, but are also applicable to all systems involving the driven motion of devices.

Abstract: An automated object detection system and method is disclosed. The automated detection system uses an imaging apparatus, such as a bar code reader, to determine if an object is located at a predetermined location. The automated object detection system has a reference surface with a target located on the reference surface. The imaging apparatus is positioned relative to the reference surface so as to image the target. The automated object detection system is adapted to have objects located in a light path between the target and the imaging apparatus so as to block the target from being imaged. If the imaging apparatus is able to image the target, the automated optical detection system may determine that no object is located between the target and the imaging apparatus. If the imaging apparatus is unable to image the target, the automated optical detection system may determine that an object is located between the target and the imaging apparatus.

Abstract: Disclosed are marine antifouling compositions and/or paints containing, microorganism(s), or mixtures of hydrolytic enzyme(s) and microorganism(s), wherein the microorganism or hydrolytic enzyme reduce fouling of a surface coated by the marine antifouling composition and/or paint. Such compositions and/or paints may contain a catalytically effective amount of an inorganic salt. Also disclosed are articles coated with the composition and/or paint. Finally, methods are disclosed for reducing fouling of a marine surface, for reducing marine corrosion, for limiting absorption of water by a marine surface, for reducing the coefficient of drag of a marine surface, removing marine growth from a marine surface, and for reducing mildew fungus on a marine surface.

Abstract: A coexecutor for executing functions offloaded from central processors (CPs) in a data processing system, as requested by one or more executing control programs, which include a host operating system (host OS), and subsystem programs and applications executing under the host OS. The offloaded functions are embodied in code modules. Code modules execute in the coexecutor in parallel with non-offloaded functions being executed by the CPs. Thus, the CPs do not need to execute functions which can be executed by the coexecutor. CP requests to the coexecutor specify the code modules which are accessed by the coexecutor from host shared storage under the same constraints and access limitations as the control programs. The coexecutor may emulate host dynamic address translation, and may use a provided host storage key in accessing host storage. The restricted access operating state for the coexecutor maintains data integrity.

Abstract: Water-soluble polymers that thicken reversibly in aqueous solution on alteration of the degree of alkalinity are manufactured by treating an aqueous suspension of protein with the enzymes elaborated extracellularly by a species of the genus Pseudomonas. The water soluble polymers resulting therefrom are biodegradable. They are useful for stabilizing emulsions, as flow-control agents in water base paint, and as anti-redeposition agents in laundry detergents. They are particularly useful as coagulants for colloidal suspensions of solids such as the phosphate slimes byproduct of the large scale hydraulic mining of phosphate deposits. They are also particularly useful as flow control agents in the water flooding process for the recovery of petroleum.
