Abstract: Systems and methods for providing identity verification services to users by providing a staking mechanism to incentivize participants in an identity verification system to be truthful and accurate and determining validator accuracy and associated setting of fees for using validator attestations to create an efficient, private and secure system.

Abstract: An elevated tank tower includes a foundation, and a support structure including a plurality of stacked segments. One or more of the plurality segment is unitarily constructed from precast concrete configured to extend around the entirety of an outer perimeter of the support structure. Each of the stacked segments is connected to an adjacent segment with one or more spanning plates connected to the adjacent segments. A superstructure is positioned atop of the support structure and operably connected to an uppermost segment of the plurality of segments. A containment tank is positioned atop the superstructure.

Abstract: A drive train apparatus (1) adapted for driving a pan and tilt head, which in use is intended to support a payload (for example a video camera), the apparatus includes respective successive drive elements (2, 3, 4) so coupled as to communicate a rotational movement applied at one end of the apparatus (1) from an output of a rotational input device (8) to a rotational output (16) disposed at the other end of the apparatus (1), in a manner whereby the rotational velocity of the rotational movement is reduced across the drive elements (2, 3, 4) thereby converting the torque applied to the input of each drive element (2, 3, 4) into an increased torque at the output of each drive element (2, 3, 4); a first stage one of the drive elements including a belt drive.
