Alternatively, instead of using indicia, the implantable medical device is located in a predetermined position within the container so that the external antenna may be place with respect to the predetermined position in order to charge the implantable medical device without disturbing the container.

Abstract: In general, the disclosure is directed to an implantable neurostimulator and system capable of providing adaptive neurostimulation therapy to alleviate incontinence. The neurostimulator operates according to a set of stimulation parameters stored in memory. During operation, information is obtained from the patient, the implanted neurostimulator, one or more implanted sensors, or some combination thereof. A processor analyzes the information to automatically generate proposed adjustments to the stimulation parameters applied by the neurostimulator. The adjustments provide an adaptive neurostimulation therapy that supports or enhances therapeutic efficacy based on the information.

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: A mechanism for steering a photoconductor belt in an electrophotographic imaging system is disclosed. The photoconductor belt is moved about a support roller system of the imaging system to form a continuous transport path. The photoconductor belt tends to deviate from this continuous transport path in a direction substantially perpendicular to the path. The belt steering mechanism includes a support carriage, a steering carriage, a support roller and a belt steering drive assembly. The steering roller is mounted to the steering carriage, and the steering carriage is connected to the support carriage so as to be pivotable about a steering axis. The belt steering drive assembly is operably coupled to the steering carriage to pivotally move the steering carriage about the steering axis.

Abstract: A system for registration of one or more color separation images on a photoconductor belt prevents misregistration that otherwise can occur between different scan lines and between different latent images due to side-to-side movement of the photoconductor belt. The registration system operates to detect movement of the photoconductor belt. Based on the detected movement, the system operates to control modulation of laser beams used to form the latent images to ensure precise registration of the color separation images. As one advantage, the movement of the photoconductor belt can be detected precisely and inexpensively by a photodetector scanned with the same laser beam used for imaging.

Abstract: Characterizing a color imaging system involves generating color values representing colors of output samples of the color imaging system.

The white reference vector is calculated using the black reference vector. Color values can be transformed between color imaging systems using the device-independent color coordinate system.

Abstract: Disclosed is a protective cover package for an endless, organic photoreceptor belt of an electrophotographic printer. The protective cover package is a flexible, closed loop sheet member which extends about an outer, photoreceptor coated surface of the endless belt. The photoreceptor coated surface of the endless belt is releasably secured to an inner surface of the sheet member, such that the sheet member supports the belt, and protects the photoreceptor surface from damage that would adversely affect the image reproduction quality of the belt. The sheet member has a belt loading configuration, that substantially duplicates the configuration of the endless belt when the belt is mounted onto support rollers of the electrophotographic printer. By replicating the configuration of the support rollers, loading of the belt onto the rollers is facilitated using the protective cover package. The sheet member also has a compact configuration that requires less volume than the belt loading configuration.

Abstract: A method for characterizing a halftone printer uses a reduced number of test patches to simulate the printing characteristics over the printer's full range of realizable color combinations. The method involves obtaining a set of color values from each of a limited number of test patches. Substantially fewer test patches are used than are necessary to adequately sample a full range of realizable color combinations. The method also involves constructing a halftone printer model using at least one device spot size parameter, the sets of color values, and a set of addressable units corresponding to device spot locations on a medium. Each addressable unit is smaller than a device spot. A set of color separations representing a page of color samples spanning the full range is generated.

Abstract: An electrophotographic imaging system including a combination erase and belt position detection system which may be employed for belt registration or image registration. In one embodiment, the system includes an erase bar having a pattern of light extending longitudinally across a photoconductor belt being moved in a first direction forming a transport path, wherein the erase bar is substantially perpendicular to the first direction. A photodetector is disposed adjacent the photoconductor belt, wherein the photodetector is responsive to light from the erase bar and provides a belt position signal representative of the position of the photoconductor belt relative to the continuous transport path, in a direction substantially perpendicular to the first direction. The belt position signal may be employed for belt steering or modulation of a laser beam representative of latent images to be scanned on the photoconductor belt.

Abstract: Disclosed is a cartridge device for packaging an endless, organic photoreceptor belt of an electrophotographic printer. The cartridge device includes a substantially rigid, closed loop support structure and a resilient mechanism. The resilient mechanism engages the endless belt and releasably holds the belt against an inner surface of the support structure. The resilient mechanism holds the endless belt so that the belt substantially conforms to the shape of the support structure. The shape of the support structure essentially duplicates the configuration of the endless belt when the belt is mounted onto support rollers of the electrophotographic printer. By replicating the configuration of the support rollers, loading of a replacement photoreceptor belt onto the rollers is facilitated using the cartridge device. The cartridge device substantially protects the photoreceptor belt from inadvertent damage that would adversely affect the image reproduction quality of the replacement belt.

Abstract: Method and apparatus of coating a plurality of wet layers on an flexible elongated web, which is economical to build and easy to operate at high speeds, and an apparatus which can be used to manufacture multi-layer magnetic recording media of the highest quality. Such apparatus can employ a gravure coater while an extrusion die both smoothes the wet gravure layer to eliminate its pattern and simultaneously extrudes a second dispersion. That smoothing is provided by a face of the upstream lip, which face has a convex shape that allows the wet gravure layer to remain in contact with the upstream lip over a wrap angle .gamma. of at least two degrees, thus ensuring that the tensioned carrier web neither buckles in the cross-web direction nor experiences instabilities such as fluttering. The extruded layer is contacted by a smooth face of the downstream lip, and the coated carrier web exits the smooth face substantially tangentially at a sharp trailing corner.

Abstract: An apparatus and method for recalibrating a multi-color imaging system are provided. The multi-color imaging system is capable of applying different colorants to a substrate based on a plurality of input color values. The input color values control amounts of the colorants to be applied to the substrate by the imaging system. A subset of the input color values is selected and used to control the imaging system to apply one or more of the different colorants to the substrate, thereby forming a plurality of different color patches on the substrate. The subset of input color values is selected such that one or more of the different color patches is formed by application of a combination of at least two of the different colorants to the substrate. Color values are measured for each of the different color patches, and compared to reference color values, representing a calibrated condition of the imaging system. An error value is calculated.
