Title: Method of token verification in a key management system
Inventor: BRAUN JOHN F
IPC: G07B17/00
Filed: 1996-03-28
Granted: 2000-05-16
Abstract: A method of token verification in a Key Management System provides a logical device identifier and a master key created in a logical security domain to a transaction evidencing device, such as a digital postage meter.   The method creates a master key record in a key verification box,  securely  stores  the master  key  record  in  a  Key Management   System   archive,   and   produces   in   the transaction  evidencing  device  evidence  in  the  logical security  domain  of  transaction  information  integrity. The  method  inputs  the  evidence  of  the  transaction information integrity to a token verification box,  and inputs  in  the  token  verification  box  the  master  key record  from the  Key Management  System  archive.    The method determines in the token verification box that the master key is valid in logical security domain, uses in the token verification box the master key to verify the evidence  of  transaction  information  integrity,   and outputs from the token verification box an indication of the  result  of  the  verification  of  the  evidence  of transaction information integrity.  The master key record includes the logical device identifier,  the master key and a digital signature associating the logical device identifier and the master key.   The method checks the digital  signature  to  verify  the  association  of  the logical device identifier and the master key within the logical security domain.

Abstract: A shroud seal having an annular ring portion and an annular lip portion. The annular ring portion is installed on the shroud of an electrical connector such that the annular lip portion is axially compressed on the shroud by a mating shrouded electrical connector. The annular ring portion has a frustoconical inner sealing surface which is sized to be twisted from its original molded frustoconical form to a cylindrical form when installed around the shroud of the electrical connector.      This twisting of the shroud seal produces a concentrated hoop stress in the seal at its points of contact with the shroud. The annular ring portion and the lip portion are compliant to allow for large axial tolerance variations between the mating electrical connectors, and provides for low insertion force between the mating electrical connector. In one embodiment, the electrical connector is in the form of a plug having a tubular portion or seal guard for encircling the shroud seal to protect the seal.      In other embodiment, the electrical connector is in the form of an inlet having a mounting flange to mount the electrical connector to a wiring enclosure.

Abstract: La présente invention concerne un procédé de dosage d'aglycanes normaux et une trousse de dosage appropriée. Le procédé consiste à séparer, dans un échantillon, les aglycanes normaux présentant une avidité par rapport à l'acide hyaluronique et les protéoglycanes ne présentant pas cette avidité, et à ne détecter que les aglycanes normaux. Les aglycanes normaux séparés sont détectés par recherche des protéoglycanes. L'échantillon est de préférence un fluide articulaire prélevé dans l'articulation examinée. Un procédé d'évaluation des informations relatives aux articulations utilisant ce procédé et cette trousse consiste à déterminer la quantité totale de protéoglycanes dans la quantité d'aglycanes normaux d'un échantillon, à comparer les informations obtenues avec celles de même nature obtenues à l'avance à propos des quantités des composés précités dans un fluide prélevé dans une articulation de référence, et à déterminer si les informations sont caractéristiques d'articulations pathologiques ou d'articulations normales, suivant qu'il y a ou non une différence notable entre elles. Les informations caractéristiques des articulations pathologiques conduisent soit à un diagnostic de polyarthrite rhumatoïde, soit à un diagnostic d'arthrite d'origine traumatique, soit à un diagnostic d'arthrite goutteuse. En médecine orthopédique, cette trousse et ce procédé sont particulièrement adaptés au diagnostic des affections articulaires car ils permettent notamment de distinguer entre articulations normales et articulations pathologiques, de déterminer la morbidité par types et pronostics d'affections articulaires et de déterminer les effets curatifs grâce à une connaissance du dosage d'aglycane normal et de la concentration d'aglycanes normaux dans les protéoglycanes totaux.

Title: Method and instrument for selecting personal compatible colors
Inventor: MACFARLANE DARBY S
IPC: G01J3/52
Filed: 1994-05-09
Granted: 2001-10-30
Abstract: Skin coloration categories are identified based upon opponent color undertones of the skin. For example, using a color measuring device (10), Hunter b value is developed from measures of blue, yellow and lightness. That value alone then determines which of several categories of skin coloration a subject's skin exhibits. Category selection is made by comparison of measured Hunter b with ranges of Hunter b values of skin color categories. Instrumentation includes the color measuring device (10), a central processing unit (15), memory (17), and an output device. The skin color Hunter b is calculated and compared to stored ranges to assign a category which is then displayed on the output device. Colors compatible with skin color categories are identified or formulated based upon broad color family designation, yellow, brown, red, etc., and a comparison of measured and stored ranges of known or specifically developed color characteristics for the particular family.
