Abstract: Systems and methods are provided for managing votes associated with elections. One exemplary method includes receiving, at a computing device, from a voting device, a selection of a voting option by a user in an election provided by an election host and generating, by the computing device, a two-part token based on the selection of the voting option where the token includes a first part indicative of an identity of the user and a second part indicative of the voting option selected by the user. The method also includes transmitting only the second part of the token to the election host to be counted in the election, thereby maintaining anonymity of the user to the election host with regard to the voting option selected by the user.

Abstract: Methods and systems for validating an interaction between a user and a service provider system are disclosed. Electronically-stored credential data for the user are retrieved (100), and a communication link (252, 223, 207) is established (102) between a user device and a service provider system. Via the communication link the retrieved user credential data is transferred (104) from the user device to the provider system, and the transferred user credential data is used (106) to validate that the user can access a service provided by the service provider system. The validation of the interaction, following receipt of the user credential data, may include processing the interaction.

Abstract: A seal support system, for use in combination with a mechanical seal installed on a piece of rotating equipment, includes a pressure vessel, one or more fluid inlets and connecting pipework between the one or more fluid inlets and the mechanical seal. A device is included to alter the fluid flow, so that a portion of the seal support system may be isolated for various purposes, such as, for example, cleaning or repurposing.
