Cryptographic methods, apparatus and systems for storage media electronic rights management in closed and connected appliances

A rights management arrangement for storage media such as optical digital video disks (DVDs, also called digital versatile disks) provides adequate copy protection in a limited, inexpensive mass-produceable, low-capability platform such as a dedicated home consumer disk player and also provides enhanced, more flexible security techniques and methods when the same media are used with platforms having higher security capabilities. A control object (or set) defines plural rights management rules for instance, price for performance or rules governing redistribution. Low capability platforms may enable only a subset of the control rules such as controls on copying or marking of played material. Higher capability platforms may enable all (or different subsets) of the rules. Cryptographically strong security is provided by encrypting at least some of the information carried by the media and enabling decryption based on the control set and / or other limitations. A secure "software container" can be used to protectively encapsulate (e.g., by cryptographic techniques) various digital property content (e.g., audio, video, game, etc.) and control object (i.e., set of rules) information. A standardized container format is provided for general use on / with various mediums and platforms. In addition, a special purpose container may be provided for DVD medium and appliances (e.g., recorders, players, etc.) that contains DVD program content (digital property) and DVD medium specific rules. The techniques, systems and methods disclosed herein are capable of achieving compatibility with other protection standards, such as for example, CGMA and Matsushita data protection standards adopted for DVDs. Cooperative rights management may also be provided, where plural networked rights management arrangements collectively control a rights management event on one or more of such arrangements.

Hard surface cleaning compositions, premoistened wipes, methods of use, and articles comprising said compositions or wipes and instructions for use resulting in easier cleaning and maintenance, improved surface appearance and/or hygiene under stress conditions such as no-rinse

The present invention provides preferred, preferably liquid, hard surface cleaning compositions, compositions with cleaning liquid composition on a substrate, compositions used with absorbent pads and implements and devices for making the process of cleaning hard surfaces and / or maintaining their appearance and hygiene easier and more effective. These compositions, along with specific instructions for use are advantageous for removal of and / or prevention of buildup of soils commonly encountered on floors, glass surfaces, counters, walls, showers and / or tubs, said compositions comprising hydrophilic polymers to render the cleaned surface hydrophilic and to improve the appearance when the surface is either not rinsed, or when the composition is incompletely removed, specific surfactant, preferably surfactant selected to minimize spotting / filming, optionally specific organic cleaning solvents to provide cleaning and wetting particularly in applications where levels of non-volatiles need to be minimized, and, optionally, anti-bacterial agents for preserving or surface activity and optionally perfumes for aesthetics.

Nonwoven highloft flame barrier

The invention relates to a nonwoven highloft flame barrier well suited for use in mattress, upholstered furniture and other end use applications where a highloft nonwoven material is desired for flame barrier purposes. A preferred nonwoven highloft flame barrier of the invention comprises a blend of fibers, that are inherently fire resistant and essentially nonshrinking to direct flame, with melamine fibers being preferred either alone or in conjunction with, for example, viscose rayon based fibers, fibers extruded from polymers made with halogenated monomers and preferably low-melt binder fibers, which are thermally activated in a highloft manufacturing process to provide low bulk density, resiliency and insulation properties in the end use application. The preferred fiber blends are designed to withstand extended periods of time exposed to open flame with minimal shrinkage of the char barrier; thereby preventing a flames from “breaking through” the char barrier and igniting underlying materials. Other component fibers can also, optionally, be included such as: natural fibers, to improve product economics in the end use application. The highloft flame barrier of this invention also allows for the manufacture of open flame resistant composite articles, while also permitting the continued use of conventional non-flame retardant dress cover fabrics, conventional non-flame retardant fiberfills and conventional non-flame retardant polyurethane foams.

Internal short detection apparatus for secondary-battery, internal short detection method for secondary-battery, battery-pack, and electronic equipment

A secondary-battery internal short detection apparatus is provided which is capable of precisely detecting an internal short being generated in a secondary-battery. In this apparatus: an electricity-quantity storage circuit stores in advance a reference electricity-quantity necessary for charging the secondary-battery from a first voltage to a second voltage; an electricity-quantity accumulation circuit measures an accumulative electricity-quantity necessary for charging the secondary-battery from the first voltage to the second voltage; and an internal short detection circuit compares the accumulative electricity-quantity measured by the electricity-quantity accumulation circuit and the reference electricity-quantity stored in the electricity-quantity storage circuit, if the accumulative electricity-quantity is larger than the reference electricity-quantity, then decides that an internal short is generated, and if the accumulative electricity-quantity is equal to, or smaller than, the reference electricity-quantity, then without deciding that an internal short is generated, rewrites the reference electricity-quantity stored in the electricity-quantity storage circuit into the accumulative electricity-quantity.
