A method of surface sealing a porous fibrous substrate is provided. According to the method, a porous fibrous substrate possessing a moisture content and a surface with pores is provided. A sealant composition is applied to a surface of the porous fibrous substrate and permitted to penetrate the surface pores of the porous fibrous substrate and undergo cure while participating in a foaming reaction with the moisture content to establish a water-resistant polymeric foam sealant impregnated into the porous fibrous substrate. The water-resistant polymeric foam sealant contains a polyurethane and/or polyurea.

A method for managing data traffic in a multi-user multiple-simultaneous-access (MUMSA) environment, for example in a code reuse multiple access (CRMA) environment or other physical environment having true random access with more than one transmission present at the same time, the method including estimating channel load for multiple users, then using the estimate of channel load to calculate a congestion threshold on an ongoing basis, at each terminal performing an experiment using that congestion threshold value and a random number generator to determine if a packet is eligible to be transmitted, transferring downstream virtual channel traffic and redistributing user terminals to affiliate with the proper downstream virtual channel.

A xerographic printer or copier includes a replaceable cartridge having a cleaning blade and carrier particle pickoff member associated with a rotating charge receptor. As the cartridge is being used, carrier particles removed from the photoreceptor by the cleaning blade are magnetically retained on the pickoff member, where the remain for the balance of the lifetime of the cartridge. When a useable lifetime of the cartridge is spent, the carrier particles are removed from the pickoff blade.

A method and apparatus provides the capability for a single function to safely use multiple register windows within the same function, with minimal additional support from the operating system, by specifying a new window pointer, the “Effective Current Window Pointer” (ECWP), to be used in conjunction with the prior art window pointer. According to the present invention, the new window pointer ECWP can be used to override the prior art window pointer in dictating from which register window the operands stipulated by the instructions to be executed are sourced/sinked. Consequently, using the method and apparatus of the invention, the number of spills to memory is reduced, the number of instructions required is decreased, resources are used more efficiently, and costly dependency problems and RAW (read-after-write) stalls are prevented.

Methods, systems, and devices are described for intelligently routing network data in satellite communication networks based on parametric sensitivities. Some embodiments of the invention provide methods, systems, and devices for routing data based on the latency-sensitivity of the data and multiple networks in a network environment. Some of these embodiments also provide for voice-over-internet-protocol capabilities to provide a network environment which allows for high throughput and low physical latency, without tying up a phone line. Other embodiments of the invention provide methods, systems, and devices for routing data based on the parametric-sensitivity of the data and multiple networks in a network environment.
摘要:
An interface antenna is positioned between a tag antenna associated with a tag and a reader antenna associated with a reader. The interface antenna receives an electromagnetic carrier signal transmitted by the reader antenna and causes an increase in intensity of the electromagnetic carrier signal at the location of the tag antenna, thereby increasing the distance over which the tag can communicate with the reader. Where the tag is attached to a packaged object, the interface antenna may be included in the package to allow wireless data communication between the tag and a reader external to the package. For example, the interface antenna may be attached to a label on the package. At least a portion of the interface antenna may be formed from a conductive ink applied to the label and/or the container. The object may be a module, also known as a customer replaceable unit (CRU), and the tag may be configured as a customer replaceable unit monitor (CRUM).
摘要:
A development subsystem is used to develop developer having semiconductive carrier particles and toner particles. The development subsystem includes a developer housing, for retaining a quantity of developer having semiconductive carrier particles and toner particles, a first magnetic roll having a stationary core with at least one magnet and a sleeve that rotates about the stationary core of the first magnetic roll, a second magnetic roll having a stationary core with at least one magnet and a sleeve that rotates about the stationary core of the second magnetic roll, and a motor coupled to the first and the second magnetic rolls to drive the rotating sleeves of the first and the second magnetic rolls in a direction that is against the direction of a photoreceptor that rotates in proximity to the first and the second magnetic rolls. The first and the second magnetic rolls carry semiconductive carrier particles and toner particles through a development zone formed by the first and the second magnetic rolls.
