Abstract: A connection assembly (100) includes a base structure (110); a backplane (120) coupled to the base structure (110), the backplane (120) including a first circuit board (122); and a tray module (140) configured to couple to the backplane (120). The tray module (140) includes a tray body (160) including a second circuit board (162); and a bridge member (150) to which the tray body (160) is moveably coupled.

Abstract: A method for inspecting contact between mating gears that includes applying a mixture to teeth of a first gear, teeth of a second gear, or the teeth of both the first and second gears. The mixture includes a lubricating oil and a fluorescing dye. The first gear is rotated to drive the second gear. While the second gear is being driven by the first gear, electromagnetic radiation, such as ultra-violet radiation, is applied to the teeth of at least one of the first and second gears to cause the teeth to fluoresce. The fluorescing teeth of the second gear are inspected to identify a tooth inspection zone that approximates a zone of contact between the teeth of the first and second gears.

Abstract: A computer implemented method comprising receiving a list of one or more contact points from a sender and comparing the list of one or more contact points to a satellite server's do-not-contact list. Any contact point on the list of one or more contact points that appears on the satellite server's do-not-contact list is reported to the sender. The satellite server's do-not-contact list is generated from a do-not-contact list distributed by a master server. A registrant registers with the master server to provide a registrant contact point to be on the do-not-contact list to be distributed by the master server. The contact points in the registry may be organized in a hierarchy with preferences at one or more levels.

Abstract: A payment system that utilises the Internet to gain access to an Internet banking system enabling a user to purchase merchandise bought through an online merchant or merchant who has Internet access in their store is disclosed. The payment system may also be utilised to provide a means for a user to retrieve and view balances and account transaction information for their bank accounts and to transfer funds between accounts. The system uses a “virtual pin-pad” which provides a web-based, stand-alone method of payment that is independent of banks and capable of performing real-time currency conversions.
