Patent number: 8683549Abstract: A computer related security mechanism requires that a human participate in an access verification sequence. Upon a request to access secure data, a puzzle is provided to the requester. Proper solution of the puzzle requires human participation. The puzzle is chosen such that its solution is within the capabilities of a human, but beyond the current state of the art for computer systems. The puzzled can be visually and/or audibly rendered to the user. In one configuration, the puzzle is obtained via a library of pluggable puzzle generators. Puzzle generators in the library can be replaced as the state of the art of computing technology improves.Type: GrantFiled: March 23, 2007Date of Patent: March 25, 2014Assignee: Microsoft CorporationInventors: Arthur H.

Patent number: 8272098Abstract: A vacuum cleaner has a hose and wand assembly onto which a floor tool may be attached. The wand includes a plurality of telescoping tubes which can slide between retracted and extended positions. In order to be able to transmit power and signals from the vacuum cleaner to the end of the wand assembly, conductors are provided in a channel in the hose. The hose is connected to the interior of the wand, just beyond the last telescoping joint, with the conductors extending beyond the end of the hose to a connector at the far end of the wand. This arrangement automatically provides a reliable electrical connection down the wand. Previously, electrical conductors were not employed with this type of wand as it was not straightforward to provide electrical connections across the telescoping parts.Type: GrantFiled: November 29, 2007Date of Patent: September 25, 2012Assignee: Dyson Technology LimitedInventor: Neil Andrew Stewart
