  • Patent number: 5372387
    Abstract: The document or substrate containing the information to be protected is covered with a liquid crystal or other such material capable of being made transparent using a process such as heating it to a higher temperature than ambient room temperature. In this manner the information on the substrate is normally invisible and thus not accessible to individuals without special equipment. For copying, the coated substrate is then placed on a copier machine in which the transparent glass plate of the copier is heated, for instance by electrical resistance heating, to a temperature matching the temperature-transparency window of the coating on the document. The information on the substrate may also be made visible for viewing by covering the coating with a transparent plate heated to the proper temperature. A second coating of different color but substantially the same temperature transparency may be selectively applied to the first coating to provide normally visible information.

  • Patent number: 5365589
    Abstract: A method and apparatus provide encryption, decryption and authentication of messages using dynamical systems. The method and apparatus preferably operate on an information stream which may comprise message information, authentication information, and random or pseudo-random information. The initial secret keys of the system are a collection of dynamical systems, at least one of which is irreversible. These keys operate on states of the dynamical systems into which the message has been encoded. To initialize the encryption, a subset of the secret keys are selected to be current keys, and the desired message is encoded into the initial states. Encryption continues over a plurality of cycles. During each cycle the current keys are applied either backward or forward in time to their current states, over a plurality of sub-cycles.

  • Patent number: 5290304
    Abstract: A trocar system comprises a trocar housing, a pointed stylet arranged so that the pointed tip can be selectively extended outwardly (distally) from the trocar housing, a return spring in the trocar housing for retracting the stylet into the housing and a piston and piston latch system disposed within the trocar housing for restraining the stylet from retracting. The piston includes a cam element for de-latching the piston from its latched position to allow the return spring to retract the piston into the housing. The stylet engages the piston in a slot to permit limited longitudinal movement of the stylet into the housing. A distally-biased element which carries an engaging pin and is forced to move proximally by the tissue resistance experienced as the trocar is forced to puncture a body cavity wall, automatically moves to its original distal location after the tip of the trocar has completely passed through the wall.
