Abstract: A multi-user access control device provides controlled access to a sensitive system by enabling/disabling an input/output port in communication with said sensitive system. Tokens are held by users and provide for confirmation of group membership and authentication. Upon authentication of the users, an enable signal is provided to a relay providing power to an external port. The external port may provide power to an input/output device allowing the user to interact with the sensitive system. The external port may provide power to a network port of the access control device allowing for management of the access control device or allowing for auditing of the access control device.

Abstract: Devices, systems, and methods securely authenticate a user, article, and/or device using an online platform or application use a multi-part cryptographic keying system and an imaging platform/device. A peer-to-peer information sharing/privacy system includes controls in a content sharing network. Devices, systems, and processes bias the purchasing power of organization or enterprise within a controlled/moderated venue to favor those more closely aligned with the interests and goals of the venue. Devices, systems, and processes are used for gaining or restricting access to an online network, environment, or communications channel, by requiring the transfer or exchange of a physical device, token, or data element. Devices, systems, and methods also integrate some or all of the forgoing together.

Abstract: The present invention is a system that offers a capability to concentrate light from a large focal point onto a small spot on a detector. The system also offers off-axis capability should the system be moved, poorly pointed, off axis or jostled while in use. As designed, the present invention includes a half-ball lens having a front end and a back end, a compound parabolic concentrator (CPC) having a front end and a back end, wherein the front end of said CPC is adjacent to the back end of the half-ball lens such that the CPC is centered against the back end of the half-ball lens, and a detector, wherein the detector is adjacent to the back end of the CPC.
