Patent CA-2066715-C (CA)
Title: Challenge-and-response user authentication protocol
Inventor: KUNG KENNETH C
IPC: G06F21/34
Filed: 1991-08-22
Granted: 1995-03-21
Abstract: A distributed authentication system that prevents unauthorized access to any computer system (10) in a distributed environment. Authentication using the present invention involves three distinct phases. In the first phase, user passwords are gener-ated by the computer system (10) and encrypted on a coded card (27) together with a message authentication code to prevent alterations prior to any access attempts. These are complex and impersonal enough not to be easily guessed. This coded card (27)must be used whenever requesting access to the system (10). Second, in addition to supplying a password, the user is required to correctly respond to a set of randomly selected authentication challenges (28) when requesting access. The correct responses (29) may vary between the right response, a wrong response or no response depending on some predetermined variable, e.g., the day of the week or hour of the day. The dual randomness thus introduced significantly reduces the usefulness of observed lo-gon information. Third, at random times during the session, the user is required again to respond to selected authentication challenges (28). This detects piggybacking at-tempts. Since authentication depends on the correctness of the entire set of responses (29) rather than on the response to a single question, the present invention provides a significant increase in the probability of detecting and preventing unauthorized com-puter access.

Title: Expandable bale carrier and feeder
Inventor: KUHNS ABE B
IPC: A01D90/12
Filed: 1992-05-08
Granted: 2003-08-12
Abstract: An expandable hay bale carrier and feeder and flexible vehicle for feeding livestock include a wheeled chassis with a bed thereon for supporting the bales, a pair of spaced end walls and a pair of spaced side walls. The side walls are mounted by a telescopically slidable assembly to move transversely of the bed between a first maximum width position spaced from the end walls and a second minimum width position adjacent the end walls. As the livestock feed and reach for more hay the force which they exert against the side walls automatically moves the side walls toward the minimum width position as the hay is consumed, and the respective ends of the side walls may move independently of each other to compensate for unequal consumption of the hay. The side walls may be opened to permit the loading and unloading of the hay bales and the livestock may feed from all sides of the feeder. The chassis is flexible to permit it to twist about a longitudinal axis if one of the wheels encounters a change in elevation in the terrain as the carrier and feeder is being moved in the field and permits the carrier and feeder to assume a low center of gravity.

Title: Clapet a bille
Inventor: KLYDE INGOLF
IPC: B62M23/00
Filed: 1991-01-30
Granted: 1999-01-05
Abstract: La soupape à bille décrite, qui est du type à tourillon, comprend un logement de soupape (1) présentant des ouvertures d'entrée et de sortie (4, 5) de préférence concentriques et dirigées dans des sens opposés (4, 5), pourvues chacune d'un siège interne (12, 12'), ainsi qu'un corps de soupape en forme de bille réversible, constituant la bille de soupape (2), qui comporte un passage traversant central (3) destiné à être sensiblement aligné sur l'entrée et la sortie (4, 5), la soupape étant en position ouverte, et qui sert à fermer le passage traversant le logement de la soupape, celle-ci étant en position fermée, tout en maintenant un état d'étanchéité au niveau des sièges (12, 12') du logement de soupape. Pour produire une soupape à bille de ce type, dans laquelle la bille est amenée mécaniquement, sans force élastique ni pression différentielle, à effectuer un mouvement de rotation dans la position fermée, maintenant ainsi une étanchéité optimale au niveau des deux sièges (12, 12') du logement de soupape, la bille de soupape (2) est pourvue de deux joints étanches diamétralement opposés (15, 15') qui, la soupape étant en position fermée, sont destinés à coopérer simultanément et hermétiquement chacun avec l'un des sièges (12, 12') du logement de soupape (1), les surfaces d'étanchéité (17, 17', 16, 16') des sièges de soupape et des joints étanches de la bille s'étendant excentriquement par rapport au point de rotation de la bille constitué par son centre géométrique. Comme les surfaces d'étanchéité des sièges et des joints étanches sont excentriques, l'effet d'étanchéité est optimisé avec une force de serrage mécanique croissante et, la soupape étant en position ouverte, au niveau de chacun des sièges (12, 12') du logement de soupape, est prévue une fente ayant une superficie d'écoulement plutôt importante vers l'intérieur du logment de soupape, ce qui permet un rinçage efficace des composants internes de la soupape au moyen d'un petit écoulement partiel du fluide passant à travers elle.

Title: Window cleaning device
Inventor: MALLORY GEORGE T
IPC: A47L1/06
Filed: 1993-02-05
Granted: 1996-04-30
Abstract: A window cleaning device of the type having a handle, a head attached to the handle and a sponge mounted in a longitudinal channel in the head of the washer is provided.   A  net-like  web  envelops  the  sponge.    The cleaning device includes an improved stiffener having an elongate body provided with a pair of shoulders extending along the body on both sides thereof.   A plurality of protrusions are integrally formed with and extend outwardly from the shoulders on both sides of the elongate body.  The stiffener has a pair of flanges one located at each end of the elongate body for locating the body in the channel and preventing movement  of  the  body  in  the channel.   The protrusions act to compress multiple portions of the sponge between the ends of protrusions and the channel walls which creates a plurality of highly compressed areas at these points adjacent less compressed areas between the highly compressed areas into which excess sponge can flow.  The action  of  the  protrusions  to  grip  the  sponge  on  the interior thereof provides a firm anchor so that the sponge cannot be removed except by dislodging the stiffener from the channel.  At the highly compressed areas portions of the sponge are forced through the perforations in the web thereby creating a locking effect between the sponge and web,  similar  to  a peg  through a  hole,  which provides increased gripping strength.   The stiffener is injected moulded from plastic.

Abstract: A power control system for a cellular mobile telephone system in which system users communicate information sig-nals between one another via at least one cell-site using code division multiple access spread spectrum communication sig-nals. The power control system controls transmission signal power for each cellular mobile telephone (16, 18) in the cellu-lar mobile telephone system wherein each cellular mobile telephone (16, 18) has an antenna, transmitter and receiver and each cell-site (12, 14) also has an antenna, transmitter and receiver. Cell-site transmitted signal power is measured as received at the mobile unit. Transmitter power is adjusted at the mobile unit in an opposite manner with respect to in-creases and decreases in received signal power. A power con-trol feedback scheme may also be utilized. At the cell-site communicating with the mobile unit, the mobile unit trans-mitted power is measured as received at the cell-site. A com-mand signal is generated at the cell-site and transmitted to the mobile unit for further adjusting mobile unit transmitter power corresponding to deviations in the cell-site received signal power. The feedback scheme is used to further adjust the mobile unit transmitter power corresponding to devia-tions in the cell-site received signal power. The feedback scheme is used to further adjust the mobile unit transmitter power so that mobile unit transmitted signals arrive at the cell-site at a desired power level. In a cell diversity situation, the mobile units transmitter power is adjusted to prevent un-necessary increases in mobile unit transmitter power level.
