Abstract: A system and method for selectively transmitting cryptographically signed information to a limited number of parties of an agreement using one or more processors. For each party affected by a decision of a first party, the processors generate a token according to a function of both (i) a cryptographic key of the given party and (ii) a cryptographic key of a second party, and transmit to respective private data stores of each party (a) the first party's decision, (b) the generated token, and (c) an identity of the second party. The decision of the first party and the generated tokens are transmitted to the private data stores of only the parties that are affected by the decision of the first party.

Abstract: The system allows for the allocation of email addresses to almost every possible person within a country, and allows for easy lookup and/or addressing of messages whether by email, telephone, mail or fax to those subscribers. It makes use of a combination of the subscriber's telephone number and an alphabetical component chosen from their name, for individuals, or an alphabetical description of a department within a business, together with a database server that stores information about each subscriber, and their preferred mode of delivery. The system requires users to create or modify their primary account by a telephone interface, as the system allows for delivery of email messages to subscribers by telephone, mail or fax, to those subscribers who do not have access to a computer and thus access to software to read their emails.

Abstract: A keyboard mechanism for musical instruments which includes a key return spring made from resilient wire bent to form a pair of flexure spring arms connected by a bight. The arms have elbow bends. The ends of the arms have wrist bends, and are trapped in apertures formed in the frame of the instrument. The bight is trapped in one of a plurality of notches on the outer surface of the key. The spring is located close to the fulcrum of the key, in order to reduce the moment arm and spring deflection, both of which contribute to undesirable force build-up.

Abstract: This is an electrical switch mechanism actuated by a piano-style key of a musical instrument. The switch consists of a pair of cross-bar contacts, at least one of which is resiliently flexible. This resilience permits a moveable contact member to be driven into engagement with a fixed contact member, and also keeps it firmly biased against the fixed contact member for electrical communication therewith whenever the key is in its actuated position. When the key is released, an actuator member on the key captures the moveable contact and moves it away from the fixed contact. Upon actuation, the key over-travels beyond the point of contact engagement, but the actuator decouples from the contact so as to avoid any increase in contact pressure and prevent double-keying. Various techniques for minimizing impact noise during contact recapture, and for mounting the contacts upon a circuit board, are also disclosed.
