摘要:
An optical interference coating for reflecting infra-red radiation and transmitting visible light. The coating comprises alternating layers of high index of refraction material and low index of refraction material. As the total number of layers increases, the ratio of high index of refraction material to low index of refraction material must also increase.
摘要:
A light source comprising a light generating element and a reflector, said reflector comprised of a generally parabolic shaped body including an at least substantially closed end and an open end, the light source disposed generally adjacent said closed end, said reflector including a light reflecting coating on both an internal and an external surface of said body, wherein a portion of said external surface of said body adjacent the closed end of the reflector is substantially devoid of said coating.
摘要:
A shroud (26) for a light producing element (46). The shroud having an elongated reflecting portion (20) with a curved cross-section and an elongated light-transmissive portion (24) with a curved cross-section. A cavity in which the light producing element is disposed is formed between the reflecting portion and the light-transmissive portion. A lamp (40) having a shroud (26) according to the invention is also disclosed as is a method of fabricating a shroud according to the invention.
摘要:
A verification method and system including a verifier which can both interpret policies and determine if they are satisfied, and request and obtain relevant certificates. This new architecture includes a verifier which itself can both direct a retrieval mechanism and use a local database of information. Users and applications can obtain and supply certificates to the verifier and the local database. The verifier may invoke a retrieval mechanism to obtain necessary certificates from other authenticated data servers and store them in a secondary database. The flexibility to allow for both on-line and off-line authenticated data server responses for verification is encompassed, as is an enhanced system for security including revocation of certificates using a polarity discipline, which allows data used for revocation to be handled with the same system used for other verification data without imperiling security.
摘要:
An electronic form routing system that includes a front-end server accessible to the users over a network via an encrypted link and a secure back-end database for storing the electronic forms and the data input by users into the form.
摘要:
A method and system automatically generate a list of participants physically present at a meeting and distribute permission to the participants. Identity and key information is collected from the participants during the meeting using at least one personal area network. The identity and key information is stored on a delegation device. Permission to access the services is distributed to the participants over at least one personal area network using the delegation device. The delegation device may include an access control matrix or moveable icons for organizing and distributing participant and permission information.
