Abstract: One aspect of the disclosure relates to a system configured for analyzing transactions between two or more parties and creating a digital token (also referred to as a hash), which can include processed and summarized information related to the transaction, to represent the evidence (or other information) associated with the transaction and store the token in a distributed ledger.

Abstract: ServiceClub provides an efficient and economic way to connect sellers of services with potential buyers of their services. Discounts, coupons, and special promotions can be provided potential customers based on geographic considerations, so a potential customer can receive services of a specific type either around where he lives or works, or currently is located. Since the system provides geographic filtering, a national or international system can provide discounts and promotions local to a user. Customers benefit because of the national system, and service providers benefit through highly focused advertising.

Abstract: An interconnection system for high density I/O sites on an I.C. Interconnection substrate allowing field replacement thereof has a socket body with an array of contact springs adapted to be removably biased into engagement with conductive pads on the bottom surface of the substrate. The contact springs have a tail portion depending from the socket body which are affixed to a printed board. The substrate is locked into place on the socket body by removable latches.

Abstract: A low insertion force connector has conductors blanked and formed from metal strip materials and disposed in openings in an insulating connector body. A receptacle portion of each conductor has a bridge formed to extend around the perimeter of a square and disposed inside a body opening and has integral leaf springs extending from the bridge at the respective sides of the square toward a terminal entry end of the opening so that two pairs of the springs are disposed in facing relation around a common axis for receiving a terminal therebetween. The contact surfaces of one pair of springs is relatively closer to the entry end of the body opening than the contact surfaces of the other pair of springs so that a terminal being inserted moves the pairs of springs separately in establishing said spring forces, thereby requiring lesser terminal insertion forces.

Abstract: A low insertion force connector has metal conductors disposed in respective openings in an insulating connector body. Each conductor has a bridge portion extending in a square inside its respective body opening and has integral leaf springs extending from respective sides of the square toward a terminal entry end of the body opening. Two pairs of the springs are disposed so that the springs in each pair face each other around a common axis for receiving a terminal therebetween. Each leaf spring has an obliquely disposed surface to intercept and be moved by a terminal as the terminal is inserted and a contact surface for engaging the terminal said surfaces of one pair of springs being relatively closer to the entry end of the body opening than said surfaces of the other pair of springs, thereby requiring lesser terminal insertion forces.
